Nutritional Value of English Walnuts.[3]

We don’t absorb all Calories of Walnuts

Walnuts are high in calories. They have 654 calories per 100g. One ounce (about 7 whole walnuts or 14 halves) has 185 calories! That’s 9% of the energy intake for a 2,000-calorie diet.

The calorie content can significantly vary among walnut varieties:

  • English Walnut (Persian Walnut): This is the most widely available and commercially grown variety. They have a smooth, light brown shell and a plump, flavorful kernel. (Calories: 654 per 100g)
  • Black Walnut: Native to North America, black walnuts have a darker, rounder shell with a more textured surface. Their kernels are slightly smaller than English walnuts and have a richer, nuttier flavor. (Calories: 619 per 100g)
  • Japanese Walnut: These walnuts have a distinctive elongated shape and a lighter-colored shell compared to black walnuts. The kernels are known for their sweetness and mild flavor. (Calories: 673 per 100g)

Calories in walnuts.

About 85% of calories of walnuts come from fat. English walnuts have more calories because they have a higher fat content. They have almost 10% more fat than black walnuts. The other calories come mainly from protein. Walnuts have low amounts of carbs and sugar.

All walnut products have many calories:

  • Walnut butter is also particularly high in calories. It contains 625 calories per 100g or 200 calories per serving (2 tbsp). [BUY here]
  • Walnut flour has 667 calories per 100g or 100 calories per 3 tbsp. [BUY here]
  • Walnut oil has 884 calories per 100g or 120 calories per tbsp! [BUY here]

Calories of popular walnut-based foods.

Most walnut varieties contain a similar calorie content per 100g, ranging from around 610 to 700 calories.

Although walnuts are high in calories, we absorb only a small percentage of them. Many calories of walnuts are burnt during digestion or lost due to incomplete chewing.[4,5]

Walnuts, like many nuts and seeds, have a tough outer cell wall made of cellulose and lignin. Our digestive system cannot break down these complex fibers completely. As a consequence, some of the fat and other nutrients trapped within these cells pass through our digestive system undigested and are eventually excreted. This reduces the total number of calories our bodies actually absorb from the walnuts.

This means a 1-ounce serving of walnuts (around 185 calories based on the label) might actually translate to 140-150 calories absorbed by your body.

The calorie count on food labels is still a valuable guideline. While we might not absorb all the listed calories, walnuts remain a concentrated source of energy due to their high fat content. It’s important to factor them into your daily calorie intake for weight management.

We absorb only 79% of calories of walnuts.[6]

Glucose Control

Walnuts, particularly when consumed with a carbohydrate-rich meal, can help slow down the absorption of glucose into the bloodstream.

They don’t spike blood sugar levels, as they have a very low glycemic index of 15. Foods with a glycemic index lower than 55 cause a slow and gradual rise in blood sugar levels.

Moreover, walnuts might improve insulin sensitivity, which helps your body utilize glucose more effectively. This could lead to better blood sugar control after a meal.

Walnuts support Weight LossPin

Stable blood sugar levels can help reduce cravings for high-calorie, sugary snacks between meals, supporting overall calorie control and weight management. They promote feelings of fullness and satisfaction after meals, reducing the likelihood of overeating and aiding in portion control.

People with diabetes could regularly consume walnuts. In fact, they seem to reduce cardiovascular risk indices in diabetes.[7]

People on keto can also eat walnuts. They typically can consume between 20–50 grams of net carbs per day depending on your individual needs and goals. One ounce of walnuts has less than 1 gram of sugar.

Walnuts promote satiety

A handful of walnuts provides 1.9 grams of fiber or almost 7% of the Daily Value. 5 walnuts have 1.36 grams of fiber or almost 5% DV.

Actually, all walnut products are rich in fiber:

ProductFiber per 100g% DV
(serving)
Walnut Flour6.7 grams4%
Walnut Butter6.3 grams6%
Walnut Bread2-4 grams3-6%
Fiber content of walnut products.

Walnuts are a good source of both soluble and insoluble fiber. They’re about 80% insoluble fiber and only 20% soluble fiber.

Soluble fiber absorbs water in your digestive system, forming a gel-like substance that slows down the passage of food through your gut. This delays stomach emptying and keeps you feeling fuller for longer.

Insoluble fiber, on the other hand, adds bulk to your stool, promoting regularity and helping you feel satisfied after a meal.

Research suggests that both soluble and insoluble fiber play a role in satiety, and including a variety of fiber sources in your diet is beneficial for overall gut health and digestion.

Healthy fats, like those abundant in walnuts (monounsaturated and polyunsaturated), can promote satiety by triggering the release of hormones like cholecystokinin and peptide YY that signal fullness to the brain.

The combination of fiber and healthy fats in walnuts can help regulate blood sugar levels. Stable blood sugar is associated with reduced hunger pangs and cravings, potentially aiding weight management efforts.

Healthy fats

The Dietary Guidelines for Americans 2020-2025 recommend a range of 20-35% of your daily calories from fat.

Aim for at least 20% of calories from fat. Fat plays a crucial role in hormone production, nutrient absorption, and satiety.

35% is considered the upper limit for most healthy adults. Exceeding this can contribute to weight gain and other health problems.

Focus on consuming healthy fats like polyunsaturated fats (found in fatty fish, walnuts, flaxseeds) and monounsaturated fats (found in avocados, olive oil).

Limit unhealthy fats like saturated fats (found in red meat, full-fat dairy) and trans fats (found in processed foods).

There’s some limited evidence suggesting that monounsaturated fats might increase fat burning and decrease abdominal fat, although more research is needed.

Ensure a balanced diet that incorporates other macronutrients like carbs and protein alongside healthy fats.

Antioxidants

Walnuts are considered a good source of various antioxidants, including polyphenols like ellagic acid and tannins. Among the most potent constituents of walnuts are the ellagitannins, primarily pedunculagin.[8]

Walnuts contain more than 20 mmol antioxidants per 100g, mostly in the walnut pellicles.[9]

Consuming walnuts every day helps maintain a high antioxidant status in the body.[10]

These compounds support gut health and immune responses and have anti-inflammatory properties. They can help scavenge harmful free radicals in the body.

Chronic inflammation is linked to various health issues, including obesity. Antioxidants can help reduce inflammation throughout the body, potentially creating a more favorable environment for weight management.

Certain antioxidants might influence hormones associated with appetite control, potentially reducing cravings and aiding weight management efforts.

Additionally, antioxidants might enhance metabolic function to a small degree.

Gut health

Walnut consumption contributes in a positive way to the gut microbiota. They have a prebiotic potential and promote the growth of beneficial bacteria.

A healthy gut microbiome can be a significant factor in your weight management journey.

Nutrient Absorption and Metabolism: The gut bacteria help break down and absorb nutrients from your food. Different types of bacteria have varying metabolic efficiencies, and some might be more adept at extracting energy from food, potentially contributing to weight gain. A balanced gut microbiome with a higher abundance of beneficial bacteria is believed to promote more efficient nutrient utilization and potentially reduce the storage of excess calories as fat.

Short-Chain Fatty Acids (SCFAs): Beneficial gut bacteria ferment dietary fiber, producing SCFAs like acetate, butyrate, and propionate. These SCFAs can stimulate the release of hormones like GLP-1 that signal satiety to the brain, potentially reducing calorie intake. SCFAs might influence metabolism and gene expression, potentially promoting fat burning and reducing fat storage.

Omega-3s

Most noteworthy, walnuts are among the richest foods in omega-3s. Omega-3s are beneficial for weight loss and improved body composition. For instance, they’re involved in the synthesis of leptin. This hormone regulates appetite and energy balance. Also, omega-3s may help obese people on a weight-loss diet burn more belly fat.[11]

Copper

Walnuts are packed with copper with just a handful providing 50% of the recommended daily intake.

Adequate intakes support weight loss, as it’s a cofactor for enzymes involved in carbohydrate and fat metabolism. It influences how efficiently your body processes energy from food.

Moreover, copper might improve insulin sensitivity, which helps your body utilize glucose more effectively. This could lead to better blood sugar control and potentially less fat storage.

Manganese

The second mineral found abundant in walnuts is manganese with a handful providing 42% DV.

Manganese acts as a cofactor for various enzymes involved in metabolism, including those involved in processing carbs, fats, and amino acids. Adequate manganese intake could ensure these metabolic processes function optimally, potentially influencing weight management.

Manganese plays a role in the production of thyroxine, a thyroid hormone that regulates metabolism. Deficiency can lead to hypothyroidism, which can contribute to weight gain and sluggish metabolism.

If manganese deficiency is present, correcting it might lead to improved metabolic function and potentially aid weight loss efforts. However, manganese deficiency is rare in developed countries with balanced diets.

Phosphorus

Walnuts are among the best dietary sources of phosphorus with 14% DV per serving.

Phosphorus is a vital mineral involved in numerous bodily processes, including energy metabolism, bone health, and cell function.

High phosphorus intake might influence appetite hormones in overweight and obese adults, leading to a temporary decrease in hunger.

High doses of phosphorus might improve diet-induced thermogenesis, the increase in calorie burning after eating.[12]

Iron

Walnuts contain decent amounts of iron. A handful provides 0.83 mg of iron which is 4.6% DV.

Iron is a vital component of hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout your body. Oxygen is essential for various bodily functions, including energy production.

Severe iron deficiency can lead to fatigue and reduced energy levels, which might indirectly hinder physical activity and potentially contribute to weight gain. Addressing iron deficiency through dietary changes or supplements, if necessary, can improve energy levels and indirectly support weight management efforts by allowing you to be more active.

Iron content of walnut products.

Magnesium

Magnesium plays a role in insulin sensitivity, which helps your body use glucose for energy effectively. This can lead to more stable blood sugar levels, potentially reducing cravings and overeating.

Also, it might have a slight thermogenic effect, meaning it helps your body burn a small amount of extra calories.

Chronic stress can contribute to weight gain by promoting unhealthy eating habits. Magnesium has calming properties and may help manage stress levels, leading to more mindful eating choices.

Additionally, magnesium is involved in protein synthesis, the process by which your body builds and repairs muscle tissue. Adequate magnesium intake can support muscle growth and recovery, which is crucial for building and maintaining a lean physique.

Walnuts with almost 11% DV per serving contribute to the daily intake.

B Vitamins

Vitamin B6 (Pyridoxine) is involved in protein and fat metabolism, aiding the body’s ability to convert these nutrients into energy. This can potentially help ensure your body uses energy efficiently and doesn’t store excess calories as fat. It might play a role in regulating appetite hormones, potentially reducing hunger and cravings.

Pantothenic Acid is a component of Coenzyme A (CoA), a crucial molecule involved in converting food into energy. Adequate pantothenic acid intake ensures your body efficiently utilizes calories from food, potentially reducing fat storage.

Riboflavin (Vitamin B2) plays a role in energy production from carbs, fats, and proteins. Efficient energy metabolism can help prevent excess calorie storage as fat.

Niacin (Vitamin B3) is involved in breaking down fatty acids for energy production. This can potentially increase calorie burning and contribute to weight management, although the effects might be modest.

Folate (Vitamin B9) is essential for metabolizing various nutrients, including fats. Adequate folate intake can ensure your body efficiently uses dietary fats for energy, potentially reducing fat storage. Folate deficiency has been linked to increased inflammation, which can contribute to weight gain. Maintaining healthy folate levels might create a more favorable environment for weight management.

Folate protects your heart

Homocysteine is an amino acid produced during protein breakdown. High levels of homocysteine in the blood are a potential risk factor for heart disease. Folate is involved in the breakdown and processing of homocysteine, converting it back into beneficial molecules.

Restrictive diets, especially those lacking fruits, vegetables, and whole grains, can increase the risk of folate deficiency.

Stimulate Collagen synthesis

Collagen can be a source of protein, which is important for satiety and muscle support during dieting.

During weight loss, especially with calorie restriction, some muscle loss can occur. Collagen is a major component of muscle tissue. It might help preserve muscle mass during dieting. Muscle tissue burns more calories at rest than fat tissue, so preserving muscle mass can contribute to a higher metabolic rate.

Collagen is the most abundant protein in the skin. It provides structure, strength, and elasticity, keeping skin firm and youthful-looking. Rapid weight loss can put stress on the body, potentially leading to a decrease in collagen production. This can contribute to looser, sagging skin.

Omega-3s, copper, iron, and protein in walnuts stimulate collagen synthesis.

Aim for gradual and sustainable weight loss through a healthy diet and exercise. This can help minimize the stress on your body and potentially support collagen production.

The role of Crunchiness in Weight Loss

When you chew food thoroughly, your body receives more signals from stretch receptors in your stomach and gut, which can contribute to feelings of fullness. This can help you feel satisfied with a smaller portion of food, potentially reducing overall calorie intake.

Crunchy foods naturally take longer to chew compared to soft foods. This can slow down your eating pace, allowing your body more time to register satiety signals and potentially preventing overeating.

The act of mindful eating, focusing on the experience of chewing and savoring your food, can be enhanced by crunchy textures. This can lead to a more conscious approach to eating and potentially better portion control.

Chewing crunchy walnuts can promote satiety and potentially reduce calorie intake.

Are Walnuts fattening?

Walnut consumption won’t make you fat if you consume fewer calories than you burn. Portion control is necessary. We should avoid consuming high amounts of calorie-dense foods like nuts.[13]

Walnut consumption can slightly increase body weight and fat mass. But only if you consume more calories than you burn. If you eat walnuts without increasing energy intake, you can actually lose weight and even preserve lean mass.[14,15]

What happens if you eat a lot of walnuts?

Eating a lot of walnuts, despite their health benefits, can lead to weight gain if you’re not mindful of portion sizes. Walnuts are delicious and can be easy to overeat, especially due to their small size and satisfying crunch.

Should I avoid using walnuts in recipes?

No, you don’t necessarily need to avoid walnuts in recipes while dieting for weight loss. Walnuts offer essential nutrients like vitamins, minerals, and antioxidants that support overall health.

Be aware of how much you’re using in recipes and avoid using excessive amounts. Consider measuring out a pre-portioned amount of walnuts before incorporating them into your dish.

Use chopped walnuts to replace unhealthy fats like butter or cheese in some recipes. This can add flavor and healthy fats while potentially reducing overall calorie content.

How to prevent overeating Walnuts?

Walnuts are a delicious and nutritious food, but with their high calorie content, it’s easy to go overboard. Here are some tips to help you enjoy walnuts in moderation and avoid overeating:

Portion Control:

  • Measure It Out: Pre-portion your walnuts using a measuring cup or scale (around 1 ounce or 28 grams). This helps avoid mindless snacking directly from the bag.
  • Single Serving Containers: Divide walnuts into individual containers or snack bags for on-the-go convenience and portion control.
  • Pair Wisely: Combine walnuts with other healthy snacks like fruits, yogurt, or vegetables to create a balanced and more filling option.
  • Top it Off: Sprinkle a small amount of chopped walnuts on salads, oatmeal, or yogurt for added flavor and texture without adding a large portion.
  • Read Food Labels: Be mindful of added walnuts in processed foods like trail mix or granola bars. Factor these in when calculating your daily nut intake.
Benefits of Walnuts for Weight LossPin

Mindful Eating:

  • Slow Down: Savor the taste and texture of each walnut by eating them slowly and mindfully. This allows your body time to register satiety signals.
  • Distraction-Free Eating: Avoid eating walnuts while watching TV, working on your computer, or driving. This can lead to mindless munching.
  • Listen to Your Body: Pay attention to your hunger cues. Eat walnuts when you’re truly hungry and stop when you’re comfortably full.
  • Plan Your Snacks: Schedule your walnut snacks in advance and stick to pre-portioned servings. Avoid unplanned snacking.

Alternatives and Strategies:

  • Substitute Other Nuts: Rotate walnuts with other healthy nuts like almonds or pistachios, offering variety and potentially helping manage portion control.
  • Freeze Portions: Freeze pre-portioned walnuts for a quick and satisfying snack when cravings strike. Frozen walnuts require more chewing, potentially promoting satiety.
  • Crush or Chop: Crushing or chopping walnuts before adding them to your food can enhance flavor and make them feel more voluminous, potentially leading to using less.
  • Spice it Up: Experiment with different spices and herbs to add flavor variety to walnuts, making you less likely to overeat for the sake of taste.

Remember, consistency is key. By incorporating these tips into your routine, you can enjoy the benefits of walnuts without overdoing it and maintain your weight loss or healthy eating goals.

Kitchen Hack

Store walnuts in an opaque container or pantry, out of sight and out of mind to reduce temptation throughout the day.

How many Walnuts can I eat a day for Weight Loss?

A typical serving recommendation is around 1 ounce (28 grams) of walnuts, which offers a good balance of nutrients and healthy fats without exceeding calorie needs. This portion is equivalent to 7 whole walnuts or 14 halves. It has 185 calories.

This serving size as part of a balanced diet is rather unlikely to make you gain weight. According to a study, even 2 ounces (56 grams) a day, being the equivalent to ≈15% of daily energy requirements didn’t increase the waist circumference and waist-to-hip ratio of participants.[16]

According to another study, the daily consumption of 10 whole walnuts (43 grams) improved the lipid profile of participants.[17]

Can I eat 20 walnuts a day?

As walnuts are high-energy foods, we should be cautious with portion sizes. As a rule of thumb, most people who follow a sedentary life and want to lose weight could eat up a a handful of walnuts a day as part of a well-balanced, energy-restricted diet.

Only active people or athletes could eat higher amounts. Long-distance endurance athletes or bodybuilding athletes in the bulking phase could eat more than 20 walnuts a day and still maintain a lean physique.

What happens if we eat 10 walnuts daily?

As part of a balanced, calorie-controlled diet for weight loss, eating 10 walnuts daily (around 265 calories) can be beneficial for losing body weight, reducing waist circumference, and improving body composition. But be mindful of exceeding your daily calorie needs. For most people, lower amounts of 4-7 walnuts a day are preferred.

Can Seniors & Kids eat 7 walnuts every day?

Yes, 7 walnuts is a safe amount for most seniors and kids to consume every day, assuming no allergies.

Digestion might slow down with age. Start with a smaller amount and see how they tolerate it.

Ensure proper chewing to avoid choking hazards. Consider chopping walnuts for younger children. Factor the walnuts into their overall calorie needs. 7 walnuts might be a higher proportion of a child’s daily intake compared to an adult.

How to eat Walnuts for Weight Loss?

With Protein sources

Protein is known for its satiating effects, helping you feel fuller for longer and potentially reducing cravings. It plays a crucial role in building and maintaining muscle mass. Muscle tissue burns more calories at rest, even when you’re not actively exercising, contributing to fat burning.

Moreover, consuming protein can slightly increase your metabolic rate, helping you burn more calories throughout the day.

The combination of healthy fats, fiber, and protein can significantly boost feelings of fullness, potentially leading to a reduced calorie intake overall.[18]

These are estimations, and actual protein content can vary depending on ingredients and portion sizes.

With Iron-rich foods

Iron deficiency is the most prevalent single micronutrient deficiency worldwide and it has been assossiated with obesity.[19]

Walnuts contain some iron (~5% DV per serving) but this isn’t enough. We absorb only a small percentage of iron of walnuts. Phytates and polyphenols in plant-based foods inhibit its absorption. The bioavailability of iron from vegetarian diets is between 5% and 12%.[20,21]

On the contrary, the bioavailability of iron from mixed diets is up to 18%. Thus, vegans, vegetarians, or people who follow a plant-based diet should consume 1.8 times more iron than people who eat meat and other animal-derived foods.

Improve Iron absorption
Vitamin CVitamin C can increase nonheme iron absorption up to 270%.
There is no need to take vitamin C supplements.

Improve Iron absorption.

Common foods high in iron are meat, poultry, fisheggs, whole grains, nuts, seeds, legumes, beans, potatoes, chocolate, and certain vegetables and fruits (e.g. avocado).

Actually, the regular consumption of beans is an easy way to significantly increase your iron intake. For instance, a serving of green peas, soy, lentils, and chickpeas provides between 25 and 50% of the DV!

Dried fruits, such as goji berries, dates, raisins, and prunes are great dietary sources of iron as well.

Furthermore, you could consume fortified foods to boost your daily iron intake. Iron in fortified foods is highly bioavailable. Many cereals are enriched with iron.

  • Yogurt Parfait with Granola, Walnuts, and Berries (5 mg iron): Layer yogurt, granola with chopped walnuts, and a variety of berries (strawberries, raspberries) in a glass for a protein-packed and iron-rich snack. Raspberries contain a unique antioxidant compound that stimulates fat burn!

With Calcium sources

Some studies suggest calcium might play a role in increasing lipolysis, the process of breaking down fat stores in the body, potentially leading to increased fat burning.

Calcium may enhance feelings of fullness, potentially reducing calorie intake throughout the day.

Don’t forget that maintaining adequate calcium intake is crucial for strong bones which is important for overall health and mobility, which can indirectly support weight management activities.

Walnuts contain between 61 and 98 mg of calcium per 100g, depending on the variety. A handful provides almost 3% DV.

English walnuts have the highest calcium content than other walnut varieties

Due to their high phytic acid content (up to 6.7 grams per 100g of dry weight), walnuts have a low calcium bioavailability. Phytic acid binds to minerals, including calcium, making them unavailable to the body.[22]

High amounts of caffeine, phosphorus, and oxalates (found mainly in spinach, collard greens, sweet potatoes, rhubarb, and beans) can decrease calcium absorption as well. That’s another reason why you should avoid drinking tea, coffee, energy drinks, or other caffeinated beverages with walnuts.

With other Omega-3-rich foods

Although walnuts are packed with omega-3s, their consumption with seafood (also rich in high-quality omega-3s: DHA & EPA) has more health benefits.

According to a study, eating walnuts with fish is more effective on blood pressure levels, fasting blood glucose, inflammatory markers, and serum lipids than consuming only fish or walnuts. Eating 18 walnuts per week along with 300 grams of fish could significantly improve these factors.[23]

Alternatively, you could take omega-3 fish oil supplements.

What’s the best time of the day to eat Walnuts for weight loss?

As a Snack

Walnuts can be a satisfying and nutrient-rich snack option, especially when cravings hit between meals. The healthy fats and protein in walnuts can help you feel fuller for longer, reducing your overall calorie intake and preventing you from reaching for unhealthy snacks that are often lower in nutrients and higher in calories. This can be especially helpful in the afternoon when energy levels tend to dip and cravings can be stronger.

At dinner

Moreover, a great time to eat walnuts is before bed. Walnuts promote a good night’s sleep. After all, people who sleep better at night have a lower risk of obesity.

At breakfast

Walnuts can be a smart addition to a balanced breakfast. The healthy fats and protein in walnuts can help you feel satisfied and energized throughout the morning, curbing cravings and preventing you from reaching for sugary or processed snacks before lunch.

This can be especially helpful if you tend to feel hungry soon after waking up. Including walnuts in your breakfast can also help regulate your blood sugar levels, promoting sustained energy and focus throughout the mid-morning hours.

Furthermore, most people can consume them on an empty stomach.

In addition, as walnuts greatly increase the antioxidant capacity of the body, they could help the body fight oxidative stress due to air pollution, sunlight radiation, or smoking.[24,25,26]

Around Exercise

Also, a great time to eat walnuts is after exercise. They’re rich in antioxidant phytochemicals, which have a beneficial effect on recovery from exercise-induced muscle damage.[27]

Strenuous workouts may lead to muscle damage, oxidative stress, and inflammation, which may be accompanied by muscle weakness and muscle soreness. Antioxidants in walnuts may attenuate these side effects.

In addition, walnut consumption may naturally increase steroid hormones, like testosterone. Even a small dose of 15 grams of walnuts (4 walnuts) a day can be beneficial for athletes. These benefits are mainly due to the high amounts of omega-3s in walnuts. Omega-3s play a significant role in muscle synthesis and recovery.[28]

On the contrary, the worst time of the day to eat walnuts is right before exercise. Walnuts are high in fiber which takes a lot of time to be digested. It may cause stomach discomfort, bloating, gas, or other adverse effects, impairing sports performance.

Dangers of eating Walnuts

While walnuts are a generally healthy nut, there are some potential downsides and dangers to consider.

Allergy: Walnuts are a common tree nut allergy. Symptoms of a walnut allergy can range from mild (itching, hives, swelling) to severe (anaphylaxis, a life-threatening reaction). If you suspect a walnut allergy, avoid them and consult a healthcare professional.

Digestive Issues: Walnuts are high in fiber, which can cause bloating, gas, or diarrhea, especially for those not accustomed to consuming them regularly. Start with a smaller amount and gradually increase intake to allow your digestive system to adjust.

Choking Hazard: Whole walnuts pose a choking hazard, especially for young children. If giving walnuts to children, chop or grind them first.

Medication Interactions: Walnuts may interact with certain medications, such as blood thinners. If you take any medications, consult your doctor before significantly increasing your walnut intake.

Oxalates: Walnuts contain oxalates, which can contribute to kidney stones in susceptible individuals. If you have a history of kidney stones, speak to your doctor about walnut consumption.

Check for signs of mold before consuming. Be wary of pre-packaged walnuts that might have been sitting for a while.

Are they worth the cost?

Walnuts can be a valuable addition to a weight loss plan, but they aren’t a magic solution. If budget is a major concern, consider alternative nuts or prioritize portion control with walnuts. Focus on a calorie deficit and combine walnuts with other healthy foods for sustainable weight loss.

Ultimately, the best choice depends on your individual circumstances. Walnuts can be a healthy and convenient option, but explore all factors before deciding if they fit your weight loss goals and budget.

Tips for buying & storing Walnuts

What’s the healthiest Variety?

There isn’t a single “healthiest” walnut variety, as all common varieties offer similar nutritional benefits.

English Walnuts (Juglans regia): Most widely available variety. Good source of healthy fats, protein, fiber, vitamins, and minerals. Considered a good all-rounder for nutrition.

Black Walnuts (Juglans nigra): Higher in antioxidants and polyunsaturated fats compared to English walnuts. Richer, earthier flavor. More challenging to crack and have a smaller edible nut compared to English walnuts.

Chandler Walnuts: Commercially popular due to their large size, light color, and ease of shelling. Similar nutritional profile to English walnuts. May be preferred by some for their milder flavor.

Heartnut Walnuts: Less common variety with a slightly elongated shape. Similar nutritional profile to English walnuts. Known for their sweeter flavor.

Ultimately, the “healthiest” walnut variety depends on your preferences.

How to choose the freshest nuts?

Here are some tips on how to choose the freshest walnuts:

Visual Inspection: Look for walnuts with whole, unblemished shells. Avoid walnuts with cracks, holes, or soft spots, as these can indicate age, spoilage, or insect infestation. Fresh walnuts have a light brown or tan shell color. Avoid walnuts with darker shells, as this might indicate they’ve been sitting for a while.

Touch Test: Pick up a walnut and give it a gentle squeeze. Fresh walnuts will feel firm and solid. Avoid walnuts that feel soft or mushy, which can be a sign of age or moisture damage.

Sound Test: Gently shake a container of walnuts. Fresh walnuts will have a minimal rattling sound. Avoid walnuts with an excessive rattling sound, as this might indicate dried-out or old nuts.

Other Tips

  • Packaging: Opt for walnuts packaged in sealed containers to maintain freshness. Avoid pre-packaged walnuts that have been sitting on shelves for a long time. Look for packaging with a “harvest date” or “packaged on” date to gauge freshness.
  • Store-bought vs. Bulk: While buying in bulk can be cost-effective, it’s harder to assess freshness. If buying in bulk, ensure the store has a high turnover rate and prioritize smaller quantities for quicker consumption.
  • Smell: Fresh walnuts have a mild, nutty aroma. Avoid walnuts with a strong, rancid odor, as this indicates spoilage.

Seasonal Availability

Walnuts are harvested in the fall (September-November) in the Northern Hemisphere. Walnuts purchased during or shortly after harvest are likely to be fresher.

How to store Walnuts to last for longer?

Transfer walnuts from their original packaging (if not resealable) to an airtight container. This minimizes exposure to air and moisture, which can accelerate spoilage. Glass jars with lids or airtight plastic containers work well.

Store walnuts in a cool, dry place away from direct sunlight and heat sources like stoves or ovens. Heat can accelerate spoilage and nut oils can become rancid. Pantries or cabinets are suitable locations.

For extended storage (up to a year), refrigerate walnuts. The colder temperature further slows down the spoilage process and preserves freshness.

Walnuts can be stored in the freezer for up to two years for maximum shelf life. Freezing is a great option if you buy walnuts in bulk.

Additional Tips

Don’t Pre-shell: Unless you plan to use them immediately, it’s best to store walnuts in their shells. The shell provides a natural barrier that protects the nut from oxidation and drying out.

Blanch for Freezing: If freezing shelled walnuts, consider blanching them first. Blanching involves briefly boiling the nuts and then submerging them in cold water to stop the cooking process. This can help preserve their texture and flavor for longer.

Portion Control: If storing walnuts in the refrigerator or freezer, consider portioning them into smaller bags or containers. This minimizes the number of times you open the main container, reducing exposure to air and moisture.

Freshness Check: Before consuming stored walnuts, do a quick freshness check. Look for any signs of mold growth, discoloration, or rancid odor. Discard walnuts if you notice any of these signs.

Are Organic Walnuts more nutrient-dense than conventional ones?

Organically grown walnuts are less likely to contain pesticide residues compared to conventionally grown ones. Furthermore, organic walnuts might have slightly higher levels of certain antioxidants compared to conventional walnuts.

However, the evidence for a significant difference in core nutrients is limited.

Both organic and conventional walnuts are a healthy choice. Choose the option that best fits your budget, priorities, and availability.

Tips to cut down the cost

Walnuts can be a delicious and nutritious addition to your diet, but they can also be pricey. Here are some tips to help you cut down on the cost of walnuts:

Buying Strategies

  • Buy in Bulk: If you use walnuts frequently, buying in bulk can be cost-effective. However, this requires good storage practices to ensure freshness. Opt for stores with high turnover to minimize the risk of buying old nuts.
  • Shop Around and Compare Prices: Prices can vary between stores. Check grocery stores, warehouse clubs (if you have a membership), and online retailers for the best deals.
  • Look for Sales and Coupons: Keep an eye out for sales and promotions on walnuts. Many stores offer discounts throughout the year. Stock up when prices are lower.
  • Consider Store Brands: Store brand walnuts can often be significantly cheaper than name brands and offer similar quality.

Alternative Purchasing Options

  • Farmer’s Markets: If you have access to farmer’s markets, you might find walnuts directly from local growers at potentially lower prices.
  • Ethnic Grocery Stores: Ethnic grocery stores might offer walnuts at a lower cost, especially if they cater to regions where walnuts are a common ingredient.

Consumption Strategies

  • Buy Shelled Walnuts: While pre-shelled walnuts are generally more expensive per weight, they can save you time and effort. This can be a good option if shelling discourages you from using walnuts regularly. However, factor in the convenience premium when comparing prices.
  • Substitute with Other Nuts: While walnuts offer unique benefits, other nuts like almonds or pecans can be used for similar purposes in some recipes. Consider incorporating these alternatives when walnuts are expensive.
  • Grow Your Own (long-term strategy): If you have the space and climate suitable for walnut trees, consider planting your own. However, this is a long-term strategy as it takes several years for walnut trees to mature and produce nuts.

Does Cooking destroy nutrients in walnuts?

Cooking can affect the nutrients in walnuts to some degree. It can degrade some heat-sensitive vitamins.

On the other hand, it might slightly improve protein digestibility in walnuts. This can be beneficial for your body to absorb the protein more efficiently.

The healthy fats and fiber in walnuts are relatively stable and aren’t significantly affected by most cooking methods.

Cooking Methods and Nutrient Impact:

  • Roasting: A common method for walnuts. It might cause some loss of vitamin E but offers the benefit of enhanced flavor and texture. Roasting has little effect on either free or total polyphenols. Raw and roasted walnuts have the highest total polyphenols.[29]
  • Baking: Similar to roasting in terms of nutrient impact.
  • Frying: High-heat frying can have a more significant impact on nutrient content, potentially affecting healthy fats and reducing some vitamins.

Opt for gentler cooking methods like roasting or baking to minimize nutrient loss.

Are Walnuts better for Weight Loss than other Nuts?

Walnuts have the highest free and total polyphenols among 9 common nuts. Raw and roasted.[29]

However, all nuts have great nutritional value. They’re particularly rich in fiber, protein, healthy fats, and minerals. You can consume them in moderation every day.

According to studies, eating a serving of nuts each day can help you maintain a lean body year-round. Nuts might help prevent gradual weight gain and even lower your risk of obesity in the long run. The trick? Swap out some less healthy snacks for nuts throughout the day. It’s a simple change that can make a big difference![30]

Small portions of nuts, as part of a well-balanced diet, can improve Body Mass Index (BMI), help control body weight, and decrease the risk of obesity.[31,32]

Each nut has a different nutritional value. For instance, almonds are particularly rich in vitamin E, Brazil nuts in selenium, and walnuts in omega-3s. Consuming a variety of nuts ensures you get a wider range of beneficial nutrients.
