Walnuts have more Magnesium than other nuts

Walnuts are among the richest nuts in magnesium. They have up to 201 mg of magnesium per 100g, while a serving provides up to 13.5% of the required daily dose! Only almonds and cashews have a much higher magnesium content.

How much magnesium is in walnuts?

Walnuts are excellent dietary sources of magnesium. They contain 158-201 mg of magnesium per 100g, depending on the variety. This amount is up to 48% of the Daily Value (DV).

For instance, English walnuts have the lowest magnesium content as compared to other walnut varieties. They have 158 mg of magnesium per 100g. A chopped cup has 185 mg of magnesium while 1/4 cup has 39 mg of magnesium or 9% of the DV. Furthermore, a handful of English walnuts provides 44.8 mg of magnesium or almost 11% of the DV.

Do we absorb the Magnesium of Walnuts?

It’s estimated that we absorb 30-50% of the magnesium in food. The absorption rate depends on the consumed dose. Higher doses of magnesium are associated with lower absorption rates.[2]

How to increase the Absorption Rates of magnesium in walnuts?

Above all, we should have normal vitamin D levels for optimal absorption of magnesium. Vitamin D at normal levels may enhance magnesium absorption. However, as vitamin D deficiency is pretty common, many people would benefit from taking high amounts of vitamin D from dietary supplements.[3]

Opt for raw walnuts over roasted or processed varieties. Some processing methods may alter the nutrient content. Raw walnuts retain their natural state.

Moreover, soaking or sprouting nuts, including walnuts, may reduce the presence of compounds known as phytates, which can inhibit mineral absorption. However, the impact on magnesium absorption may not be as significant.

Mixing walnuts into Greek yogurt or kefir may improve magnesium absorption rates as well. Yogurt and kefir are the richest common foods in probiotics that may positively influence mineral absorption. As kefir is the richest food in probiotics, it has huge benefits for weight loss and gut health.

What inhibits the absorption of magnesium in Walnuts?

We may absorb less magnesium from walnuts if we:

  • consume too many foods high in phytate, such as beans, whole grains, and nuts.
  • get high doses of zinc or vitamin D. Also, too much zinc may interfere with the absorption of calcium. Walnuts have decent amounts of calcium as well.
  • smoke
  • drink too much alcohol
  • take certain drugs

What’s the recommended daily intake?

The recommended daily intake of magnesium is approximately 420 mg for adult men and 320 mg for adult women. Teenagers and pregnant women have high magnesium needs (360-410 mg) as well. Children require lower dosages.

Do walnuts help us meet our daily needs for magnesium?

Actually, walnuts and most nuts help us meet our daily needs for magnesium. A serving provides up to 18% of the DV.

However, we should be very cautious with portion sizes. Overconsumption of walnuts can make you gain weight. Walnuts have many calories! However, reasonable amounts support weight loss.

Always consult your physician before changing your diet.

Health benefits of magnesium

Magnesium is vital for good health. It’s the 4th most abundant mineral in the body. It acts as a cofactor for more than 300 enzymes and plays a key role in DNA synthesis! 

Magnesium is involved in energy production, glycemic control, protein synthesis, myocardial contraction, blood pressure regulation, nerve transmission, muscle contraction, and muscular relaxation.

Also, magnesium plays a key role in bone development and mineralization. It’s essential for the metabolism and activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. Thus, adequate magnesium intake decreases the risk of osteoporosis.[4]

Furthermore, magnesium is necessary for the synthesis of glutathione, which is a powerful antioxidant. Thus, it helps the body fight oxidative stress.
