My Story
I always thought I was making the right choice. As a busy mom in my 40s, juggling work, kids, and life, I was always on the lookout for quick, healthy snacks. That’s how I fell in love with roasted hazelnuts. They were crunchy, delicious, and packed with nutrients. Instead of reaching for chips or candy, I’d grab a handful of hazelnuts and feel good about my decision.
At first, I didn’t notice any changes. I enjoyed them daily—sometimes a small bowl while working, other times a quick handful on the go. They were so satisfying that I never felt deprived, which I thought was a win.
But after a few months, I realized something: my jeans were getting tighter. At first, I blamed stress, hormones, or lack of exercise. But when I stepped on the scale, the numbers didn’t lie—I had gained weight.
Confused, I took a closer look at my diet. I wasn’t eating more junk food, and my meals were still relatively balanced. That’s when it hit me—hazelnuts. Those innocent little nuts were calorie-dense, and my “healthy snack” was adding hundreds of extra calories to my day.
Just one ounce of hazelnuts has around 180 calories, and I was easily eating two or three times that without realizing it.
Cutting back was hard. I had grown so accustomed to snacking on them that I had to retrain myself. I switched to smaller portions and added other lower-calorie snacks like fruit and veggies.
Slowly, my weight stabilized, and I felt back in control. I still enjoy hazelnuts, but now I treat them for what they are—an energy-dense food that’s best in moderation.
Lesson learned: even the healthiest foods can lead to weight gain if you overdo them. It’s all about balance.
History
Hazelnuts have been a part of the human diet for thousands of years. Archaeological evidence suggests that hazelnuts were consumed as early as 7,000 BCE in Mesolithic Europe.[1,2]
In some parts of Britain and Scandinavia, large-scale hazelnut shell remains have been found, indicating that they were an important food source for early hunter-gatherer societies. These nuts provided essential fats, proteins, and calories, making them a valuable resource for survival.
People in the ancient Mediterranean region did eat hazelnuts as well. The Greeks and Romans were familiar with hazelnuts, and they were cultivated and consumed throughout the region.[3]
The Greek philosopher Theophrastus (circa 371–287 BCE) mentioned hazelnuts in his writings on plants.
The Romans also valued hazelnuts, not only for food but also for medicinal and symbolic purposes. They believed hazelnuts could bring good luck and used them in herbal remedies for various ailments.
The nuts were likely consumed in a variety of ways—raw, roasted, or ground into pastes. They were probably included in meals and desserts, and even mixed with honey or wine, common practices in ancient Mediterranean cuisine.
Hazelnut oil may have also been extracted for cooking or medicinal use, though olive oil remained the dominant oil source in the region.
During the Middle Ages, hazelnuts remained a staple food in many European and Mediterranean diets. They were particularly important in monastic communities, where they were cultivated in gardens and used as a source of protein during fasting periods.
Hazelnut trees were also planted in hedgerows and small farms, contributing to agroforestry systems that provided both food and wood resources.
By the Renaissance period, hazelnuts were well-integrated into European agriculture. They were used in cooking, confectionery, and even cosmetics. Historical records show that hazelnut oil was used as an alternative to olive oil, especially in regions where olives did not thrive.
Today, hazelnuts are a commercially important crop, with Turkey being the largest producer, accounting for around 70% of global production. Italy, the United States (particularly Oregon), and Spain are also significant producers.
The global demand for hazelnuts has increased due to their use in confectionery products such as Nutella, chocolate spreads, and pralines.
Myths and Folklore about Hazelnuts
Throughout history, hazelnuts have been surrounded by myths and beliefs, from granting wisdom in Irish legends to protecting against witches in Germanic folklore. Whether seen as magical tools, symbols of love, or sources of divine knowledge, hazelnuts have played a significant role in the folklore of many cultures.
Even today, some of these traditions persist in rural areas, keeping the ancient mystique of the humble hazelnut alive.
Celtic and Druidic Legends: The Nuts of Wisdom
One of the most famous myths surrounding hazelnuts comes from Celtic folklore. In ancient Ireland, hazelnuts were associated with wisdom and inspiration.
The story of the Salmon of Knowledge is one of the best-known legends. According to the tale, nine hazel trees grew around a sacred well, and their nuts contained all the wisdom of the world. As the nuts fell into the water, they were eaten by a salmon, which then absorbed their knowledge.[4]
A druid named Finegas spent years trying to catch this salmon, believing that whoever ate it would gain infinite wisdom.
However, when he finally caught the fish, his young apprentice, Fionn mac Cumhaill, accidentally tasted it while cooking. As a result, Fionn became one of the greatest warriors and leaders in Irish mythology, possessing immense wisdom and foresight.
Norse Mythology: Hazelnuts as Symbols of Protection
In Norse mythology, hazel trees were associated with protection and magic. They were considered sacred to Thor, the god of thunder, and were believed to ward off lightning strikes.
People planted hazel trees near homes and carried hazel wands to protect themselves from evil spirits.
Additionally, in some Scandinavian folktales, hazelnuts were used in fertility rituals, as they were thought to enhance love and ensure a strong lineage.
Germanic and Slavic Traditions: Divination and Witches
Hazelnuts also appear in Central and Eastern European folklore, often linked to magic and divination.
In German and Slavic traditions, young women used hazelnuts for fortune-telling, particularly in love-related matters. On special nights, such as Halloween or Christmas Eve, they would place hazelnuts near a fire and interpret their movement to predict their future husband’s faithfulness or identify rivals in love.
On the darker side of folklore, hazelnuts were sometimes linked to witches. In some regions, people believed that witches could use hazelnut branches to cast spells or locate buried treasure.
However, in contrast, hazel wood was also used to make protective charms to ward off witches and evil spirits. Some even believed that carrying a hazelnut in their pocket could prevent bewitchment.
Italian Folklore: Hazelnuts and Fairies
In parts of Italy, especially in rural areas, hazelnuts were associated with fairies and hidden forest creatures. Some believed that offering hazelnuts to the spirits of the forest could bring good luck, while others thought that hazelnut trees were inhabited by magical beings who protected nature.
Farmers sometimes planted hazel trees near their homes, hoping that the spirits would bless their land with fertility and prosperity.
Health Benefits
Packed with vitamins, minerals, healthy fats, antioxidants, and plant compounds, they offer a range of benefits, including heart health support, weight management, improved brain function, and reduced inflammation.
Rich in Heart-Healthy Monounsaturated Fats
Hazelnuts are an excellent source of monounsaturated fats (MUFAs), particularly oleic acid, which is also found in olive oil. These healthy fats help lower LDL (bad) cholesterol and increase HDL (good) cholesterol, reducing the risk of cardiovascular disease.
Research suggests that a diet rich in monounsaturated fats can help regulate blood pressure, reduce inflammation, and improve artery function, all of which are crucial for heart health.
High in Antioxidants for Cellular Protection
Hazelnuts contain a variety of antioxidants, which help neutralize harmful free radicals that cause cellular damage and contribute to aging and chronic diseases.
One of the most potent antioxidants in hazelnuts is vitamin E, which plays a crucial role in protecting cell membranes from oxidative stress. Studies show that vitamin E may reduce the risk of heart disease, Alzheimer’s, and some cancers.
Other antioxidants found in hazelnuts include polyphenols, which have anti-inflammatory properties and support cardiovascular health. The proanthocyanidins in hazelnuts are particularly effective at fighting oxidative stress and improving blood vessel function.
Excellent Source of Essential Vitamins and Minerals
Hazelnuts provide a wide array of vitamins and minerals that are essential for health:
- Vitamin E: A powerful antioxidant that supports skin health, immune function, and brain protection.
- Vitamin B6: Important for brain health, neurotransmitter function, and energy production.

Supports Brain Health and Cognitive Function
Hazelnuts are rich in brain-boosting nutrients such as vitamin E, magnesium, and folate, all of which support cognitive function and protect against neurodegenerative diseases.
The polyphenols in hazelnuts help improve blood flow to the brain, while their healthy fats support nerve cell membranes and reduce inflammation in the brain.
Studies have linked higher intake of nuts, including hazelnuts, to improved memory, reduced risk of Alzheimer’s disease, and better overall mental performance.[6,7,8]
Promotes Digestive Health with Fiber
Hazelnuts are a good source of dietary fiber, which is essential for a healthy digestive system. One serving (about 28 grams) provides 2.7 grams of fiber, which supports bowel regularity, prevents constipation, and feeds beneficial gut bacteria.
A high-fiber diet has also been linked to a lower risk of colon cancer, improved weight management, and better blood sugar control.
May Aid in Weight Management
Although hazelnuts are calorie-dense, their combination of fiber, protein, and healthy fats can promote satiety and reduce hunger cravings. Studies suggest that nuts like hazelnuts help regulate appetite by increasing leptin, the hormone that signals fullness.
The monounsaturated fats in hazelnuts may also enhance fat oxidation, making them beneficial for weight loss when consumed in moderation.
Additionally, hazelnuts have a low glycemic index (GI), meaning they don’t cause significant blood sugar spikes, making them a good snack option for those managing diabetes or looking to control their weight.
Also, research indicates that hazelnuts have a lower effective calorie count than their total fat content suggests, due to reduced fat absorption.
Anti-Inflammatory Effects
Hazelnuts are rich in phytochemicals such as phytosterols, flavonoids, and carotenoids, which have strong anti-inflammatory and immune-boosting effects:
- Phytosterols: These plant compounds help lower cholesterol levels and support heart health.
- Flavonoids: Powerful antioxidants that reduce inflammation and improve circulation.
- Carotenoids (lutein and zeaxanthin): Essential for eye health, helping to prevent age-related macular degeneration.
The combination of these bioactive compounds makes hazelnuts a functional food that may help prevent chronic diseases like diabetes, heart disease, and certain cancers.
Supports Bone Health
Thanks to their high content of magnesium, manganese, and calcium, hazelnuts contribute to bone strength and density. Magnesium helps regulate calcium absorption, while manganese plays a role in collagen formation and bone mineralization.
Regular consumption of magnesium-rich foods like hazelnuts has been associated with a lower risk of osteoporosis.
Benefits Skin and Hair Health
The high levels of vitamin E and healthy fats in hazelnuts make them excellent for skin elasticity, hydration, and protection against UV damage. Vitamin E helps reduce signs of aging by neutralizing free radicals and supporting collagen production. The healthy fats in hazelnuts also nourish the scalp, promoting stronger and shinier hair.
Don’t eat Hazelnuts
If you want to maximize the health benefits of hazelnuts while maintaining weight loss, the best choice is to eat them raw, unsalted, and with the skin intact.
Blanched Hazelnuts: Nutrient Loss
Blanching involves removing the skin of the hazelnut by soaking them in hot water or exposing them to high temperatures.
While this improves texture and taste, it removes a significant portion of antioxidants, fiber, and polyphenols, which are concentrated in the skin. These compounds are essential for reducing inflammation, protecting against oxidative stress, and promoting gut health.
Choosing raw hazelnuts with the skin intact ensures you get the full antioxidant and fiber benefits.
Roasted Hazelnuts: Oxidation and Acrylamide Risks
Roasting enhances the flavor and crunch of hazelnuts, making them more appealing.
However, the process destroys some heat-sensitive vitamins like Vitamin E and B vitamins, which play a crucial role in skin health and metabolism.
Additionally, high temperatures can cause the healthy monounsaturated fats in hazelnuts to oxidize, creating potentially harmful compounds that may contribute to inflammation and heart disease.
Another concern is acrylamide, a chemical that forms when nuts are roasted at high temperatures. Studies suggest that acrylamide may be carcinogenic in high amounts and could pose a health risk over time.[7,8]
While occasional consumption of roasted hazelnuts is unlikely to be harmful, making them a daily snack could expose you to unnecessary toxins.
Hazelnut Butter: Added Fats and Sugar
Hazelnut butter can be a nutritious alternative if made from 100% hazelnuts, but many commercial brands add oils, sugars, and salt to enhance flavor and texture. These additions can increase calorie content significantly and promote weight gain if consumed in excess.
Additionally, some oils used in nut butters, such as palm oil, are highly processed and may contain trans fats, which are harmful to heart health.
If you enjoy hazelnut butter, opt for a pure version with no added ingredients or make your own at home to control the quality.[BUY HERE]
Hazelnut Spreads Like Nutella: A Sugar Bomb
Nutella and similar hazelnut spreads are far from a healthy choice. While they contain some hazelnuts, they are loaded with sugar, palm oil, and artificial additives.
A 2-tablespoon serving of Nutella has around 21 grams of sugar, which is more than half of the daily recommended limit for women. High sugar intake can contribute to weight gain, insulin resistance, and an increased risk of metabolic diseases like diabetes.
Additionally, palm oil, commonly used in these spreads, has been linked to inflammation and poor heart health when consumed in large amounts. It also raises environmental concerns, as palm oil production contributes to deforestation and habitat destruction.
How Many
Eating too many can lead to weight gain, especially if you are not mindful of your overall calorie intake. However, the right amount of hazelnuts varies depending on age, lifestyle, and specific health needs.
A standard serving size of hazelnuts is 1 ounce (28 grams), roughly 20 whole nuts. This portion provides a healthy dose of fiber, protein, healthy fats, and essential nutrients without excessive calories. However, if you’re trying to lose weight, 5–10 hazelnuts may be a better daily portion to enjoy the health benefits while controlling calorie intake.
According to a study, participants who ate 40 gram of hazelnuts every day for 6 weeks, didn’t gain any weight. Researchers believe that hazelnuts prevent weight gain by increasing the antioxidant capacity of the body![9]
Be cautious with whole nuts for kids under 5 due to choking hazards—crushing or blending them into meals is safer.
| Group | Recommended Portion (Hazelnuts per Day) | Notes |
|---|---|---|
| General Adults & Middle-Aged | 10–20 nuts (about 1 oz) | Balanced intake for overall health. Limit to 10 if aiming for weight loss. |
| Kids (4–12 years old) | 5–10 nuts | Supports brain development and growth. Crush or blend for younger kids. |
| Seniors | 10–15 nuts | Helps heart health, brain function, and bone strength. Be mindful of metabolism slowdown. |
| Pregnant Women | 10–15 nuts | Provides folate, iron, and healthy fats for fetal development. Avoid excessive intake. |
| Athletes & Highly Active People | 20–30 nuts | Great for muscle recovery and sustained energy. Higher energy needs allow for more. |
General Daily Portion: 10–20 Hazelnuts
How to Avoid Overconsumption
Here are some practical tips to prevent overconsumption:
- Measure Your Portion: Pre-portion 10–20 nuts instead of eating straight from a bag.
- Combine with Other Foods: Pair hazelnuts with fruit, yogurt, or whole grains to make them more filling.
- Eat Mindfully: Hazelnuts are easy to overeat, so avoid snacking on them mindlessly while watching TV.
- Avoid Salted or Sugar-Coated Hazelnuts: These can lead to excess sodium and sugar intake.
Raw hazelnuts are the best choice as they retain more nutrients, especially antioxidants, polyphenols, and fiber from the skin. However, roasted hazelnuts can still be healthy if they are dry-roasted without added oils or salt.
Since roasting reduces some heat-sensitive vitamins (like Vitamin E) and may oxidize healthy fats, it’s best to eat slightly fewer roasted hazelnuts than raw ones. If you normally eat 20 raw hazelnuts, limit roasted ones to 15–18 nuts to reduce the risk of consuming damaged fats or oxidized compounds.
How to eat hazelnuts smartly:
- Eat them as a Pre-Meal Snack: A few hazelnuts before meals can reduce hunger and prevent overeating.
- Pair with Protein: Combine them with Greek yogurt, cottage cheese, or eggs to enhance satiety.
- Add to Salads or Oatmeal: Instead of eating them alone, mix them into meals for controlled portions.
- Avoid Nut Butters & Nutella: These are calorie-dense and often have added sugars and oils, making them easy to overconsume.
10–20 raw hazelnuts daily is a great range for most people, while those aiming for weight loss should stick to 5–10 nuts. Roasted hazelnuts are fine in moderation, but raw ones provide the best nutrient retention.
Best Time to Eat Hazelnuts
Morning
Eating hazelnuts in the morning, especially as part of breakfast, helps provide steady energy throughout the day. Their combination of healthy fats, fiber, and protein keeps you full for longer, preventing cravings and overeating later.
Pairing them with Greek yogurt, oats, or a smoothie can boost metabolism and promote weight management.
Since hazelnuts are rich in B vitamins and magnesium, they also support brain function and productivity, making them a great choice for work or study.
Pre-Workout
For those engaging in physical activity, hazelnuts can be an excellent pre-workout snack. Their healthy fats and slow-digesting carbohydrates provide sustained energy, while their magnesium content supports muscle function.
Eating half a handful at least 60 minutes before a workout can help prevent fatigue and enhance endurance.
Afternoon
Many people experience an afternoon energy slump due to a drop in blood sugar levels. Instead of turning to sugary snacks, a small handful of hazelnuts with fruit or dark chocolate can keep energy stable and prevent cravings for unhealthy foods.
Their protein and fiber content also helps with satiety, reducing the risk of overeating at dinner.
Nighttime
Hazelnuts contain magnesium, tryptophan, and vitamin E, which support relaxation and sleep. Magnesium helps regulate melatonin, the sleep hormone, making hazelnuts a great addition to an evening snack.
When to Avoid Eating Hazelnuts
While hazelnuts contain sleep-supporting nutrients, eating too many at night can cause digestive discomfort, making it harder to sleep. Stick to a small portion if consumed before bedtime.
Some people find that eating nuts first thing in the morning on an empty stomach can cause bloating or stomach upset. If this happens, pair them with other foods like yogurt or fruit.
Hazelnuts digest slowly due to their fat content, which can cause discomfort if eaten right before a high-intensity workout like running. Instead, opt for a lighter carb-based snack before cardio and save hazelnuts for post-workout recovery.
Dangers
While hazelnuts offer many health benefits, they are not suitable for everyone. Overconsumption or individual sensitivities can lead to adverse effects, ranging from mild digestive discomfort to severe allergic reactions.
Allergic Reactions – A Serious Concern
Hazelnuts are one of the most common tree nut allergens, and reactions can range from mild to life-threatening. People with nut allergies, particularly those allergic to birch pollen (oral allergy syndrome) or other tree nuts like walnuts, should avoid hazelnuts altogether.
Symptoms of hazelnut allergy may include:
- Itching or swelling of the mouth, lips, or throat
- Skin reactions such as hives or eczema
- Digestive issues like nausea, vomiting, or diarrhea
- Anaphylaxis (severe cases), which can cause difficulty breathing and requires immediate medical attention
Even if you don’t have a diagnosed allergy, if you experience any itching, swelling, or discomfort after eating hazelnuts, consult an allergist before continuing consumption.
Digestive Problems from Overconsumption
Hazelnuts are high in fiber (about 2.7g per ounce), which can be beneficial in moderate amounts but problematic in excess. Eating too many hazelnuts in one sitting may cause:
- Bloating and gas – Due to their fiber and fat content, they take longer to digest.
- Diarrhea or constipation – Overconsumption can upset gut balance, especially in those with sensitive digestion.
- Stomach pain – Some people experience discomfort due to the slow digestion of nuts.
Who should be cautious?
- People with irritable bowel syndrome (IBS) or sensitive digestion should start with small amounts to see how their body reacts.
- Those who are not used to a high-fiber diet should gradually increase nut consumption to avoid digestive discomfort.
Oxalates and Kidney Stone Risk
Hazelnuts contain moderate amounts of oxalates, which in excess can contribute to kidney stone formation in susceptible individuals. People prone to calcium oxalate kidney stones should be cautious about consuming large quantities of nuts, including hazelnuts.
Who should limit hazelnut intake?
- Those with a history of kidney stones should consult a doctor before eating nuts regularly.
- Individuals on a low-oxalate diet should consume nuts in moderation and drink plenty of water.
May Affect Nutrient Absorption
Hazelnuts contain phytic acid, an anti-nutrient that can reduce the absorption of iron, zinc, and calcium. While this is generally not a concern for those with a varied diet, it may be an issue for:
- People with iron deficiency or anemia
- Individuals on a plant-based diet who already consume high-phytate foods
Soaking or roasting hazelnuts can reduce phytic acid content, improving nutrient availability. However, roasting may slightly reduce heat-sensitive nutrients like vitamin E.
Risk of Weight Gain
Hazelnuts are nutrient-dense but calorie-rich, with one ounce (28g) providing around 180 calories. If eaten in large portions without adjusting for overall calorie intake, they can lead to weight gain rather than weight loss.
Potential for Aflatoxin Contamination
Like other nuts, hazelnuts can be contaminated with aflatoxins, toxic compounds produced by certain molds. Aflatoxin exposure is linked to liver damage and an increased risk of liver cancer.
How to minimize risk?
- Buy high-quality, fresh hazelnuts from trusted sources.
- Store them in a cool, dry place to prevent mold growth.
- Avoid nuts that taste bitter or rancid, as they may be spoiled.
Medication Interactions
Hazelnuts have a cholesterol-lowering and blood sugar-regulating effect, which is usually beneficial. However, in some cases, they may enhance the effects of certain medications, such as:
- Blood-thinning medications (Warfarin, aspirin) – Due to hazelnuts’ vitamin K content.
- Diabetes medications (Metformin, insulin) – As hazelnuts may lower blood sugar, combining them with medication may lead to hypoglycemia (low blood sugar levels).
Always consult your doctor before making dietary changes.
| Group | Recommendation |
|---|---|
| People with nut allergies | Avoid completely due to risk of severe reactions. |
| Those prone to digestive issues (IBS, bloating) | Start with small amounts to test tolerance. |
| People with kidney stones | Limit intake due to oxalate content. |
| Individuals trying to lose weight | Stick to measured portions (10–15 nuts). |
| People taking blood sugar or blood-thinning medication | Consult a doctor for possible interactions. |
| Pregnant women | Generally safe, but stick to moderate portions. |
Do Hazelnuts Damage the Environment?
Hazelnut farming, like any agricultural practice, has an environmental footprint. While hazelnuts themselves are not as resource-intensive as other crops, they still pose several environmental concerns, particularly with regard to land use, water consumption, and pesticide use.
In some regions, hazelnut cultivation has contributed to deforestation, especially in parts of the Mediterranean and Eastern Europe. The expansion of hazelnut orchards can sometimes lead to habitat destruction and a reduction in biodiversity. When forests are cleared for new farmland, this disrupts local ecosystems and wildlife habitats.
Hazelnuts require significant amounts of water, especially in drier areas where irrigation is necessary. In places where water resources are already scarce, intensive hazelnut farming could exacerbate water scarcity issues.
While hazelnut trees tend to be more resilient than other crops, pesticide use still occurs in conventional farming. This can affect the surrounding environment, harming local pollinators, soil health, and water quality.
Sustainable Hazelnut Farming
Sustainable hazelnut farming focuses on minimizing environmental impact, conserving water, using fewer pesticides, and protecting local ecosystems. There are various sustainable farming practices that can be employed:
- Agroforestry Practices: Integrating hazelnut cultivation with other types of crops or trees in a multi-layered system can help improve soil health, promote biodiversity, and prevent soil erosion. Agroforestry also reduces the need for chemical fertilizers and pesticides.
- Water Conservation: Efficient water use practices like drip irrigation and rainwater harvesting can minimize water consumption, making hazelnut farming more water-efficient and reducing its environmental impact.
- Organic Farming: Organic hazelnut farming avoids synthetic pesticides and fertilizers, focusing instead on natural fertilizers, crop rotation, and pest management techniques. This helps preserve soil health and reduces pollution from chemicals.
- Certification Programs: Look for certifications like Fair Trade or Rainforest Alliance for hazelnuts, as these programs encourage sustainable farming practices and ensure that farmers adhere to environmentally friendly standards.
Do Other Nuts Have a Lower Environmental Impact?
While all nuts have some environmental impact, some are considered more sustainable than others:
- Almonds: Almond farming has a high environmental cost, primarily due to the massive water usage. It takes about 1.1 gallons of water to produce a single almond, which has led to criticism, especially in regions like California where water scarcity is an issue.
- Cashews: Cashew farming can contribute to deforestation in tropical areas, and like hazelnuts, the labor conditions in cashew processing have raised concerns. However, sustainable cashew farming exists, particularly through Fair Trade and organic certifications.
- Walnuts: Walnuts, like hazelnuts, also require a fair amount of water, but the environmental impact is generally lower compared to almonds. Sustainable walnut farming practices can include conservation tillage and better water management techniques.
- Pecans: Pecans generally have a lower environmental impact than almonds and hazelnuts because they are often grown in regions with natural irrigation. However, their production can still involve pesticide use and monoculture farming practices.
In terms of overall environmental sustainability, hazelnuts tend to be somewhat more environmentally friendly than almonds but less so than some of the more water-efficient nuts, like peanuts or macadamia nuts.
What Can You Do to Support Sustainable Hazelnut Farming?
As a consumer, there are several steps you can take to minimize the environmental impact of hazelnuts:
- Buy Certified Organic or Fair Trade Hazelnuts: Look for hazelnuts with certifications like Rainforest Alliance, Fair Trade, or Organic. These certifications ensure that the hazelnuts are grown using sustainable practices, including no synthetic pesticides, water conservation, and fair wages for workers.
- Support Local or Small-Scale Farmers: If possible, buy hazelnuts from local farmers or cooperatives that focus on agroecology and sustainable practices. By buying locally, you reduce the carbon footprint associated with transportation and support small-scale, more eco-friendly farms.
- Minimize Waste: Hazelnuts are often sold in bulk bins or recyclable packaging. Try to minimize the environmental impact by buying in bulk or selecting brands that prioritize sustainable packaging. Also, avoid hazelnut products that use excessive amounts of plastic.
- Diversify Your Nut Consumption: While hazelnuts are great, it’s beneficial to diversify your nut intake. Supporting a variety of nuts (like almonds, walnuts, and pecans) grown in sustainable farming systems will help balance out environmental costs.
Hazelnuts vs. Other Nuts
