Benefits of Nuts: 8 Varieties to Include in Your Daily Menu
Nuts are among the most nutrient-dense foods nature has to offer. A single handful packs healthy fats, vitamins, minerals, antioxidants, and plant-based protein. The benefits of nuts go far beyond simple snacking — consumed in moderation, around 30 grams a day, they support heart health, brain function, skin vitality, immune defense, and metabolism.
They keep you full for longer, stabilize blood sugar, and are an invaluable ally during fasting. Vary your daily intake, because each type of nut champions a different nutritional category. Add them to yogurt, cereal, salads, or smoothies. Here are 8 nuts and the unique power each one brings.
1. Almonds — The Vitamin E Champion
Almonds are the richest nut source of vitamin E — a powerful antioxidant that protects cells from oxidative stress. A 30-gram serving contains approximately 7.3 mg of vitamin E, covering nearly half of the daily requirement. They also provide magnesium, calcium, fiber, and plant protein. Vitamin E shields cell membranes and slows skin aging, promoting a natural glow.
Magnesium helps regulate blood sugar, making almonds one of the healthiest nuts for people with insulin resistance. Their high fiber content supports digestion and prolongs the feeling of fullness.
Tip: Soak almonds in water for 10–12 hours before eating. This neutralizes phytic acid and enzyme inhibitors, improves nutrient absorption, and makes them easier to digest.
2. Walnuts — The Brain Nut with Omega-3
Among the many benefits of nuts for the brain, walnuts stand out as the only nut with a truly high content of alpha-linolenic acid (ALA) — a plant-based omega-3 fatty acid. It is no coincidence that the shape of the kernel resembles the brain’s hemispheres — nature seems to hint at their purpose. Learn more about this remarkable nut in our detailed article on the benefits of walnuts.
Omega-3 fatty acids support cognitive function, improve memory and concentration, and have proven neuroprotective effects. Walnuts also contain polyphenols with potent anti-inflammatory properties, reducing the risk of cardiovascular disease. Studies show that regular walnut consumption can improve vascular elasticity and lower LDL (bad) cholesterol levels.
Tip: 3–5 walnuts a day are enough for a full dose of omega-3 from a plant source.
3. Hazelnuts — Rich in B Vitamins
Hazelnuts stand out for their high content of vitamin B6, folic acid (B9), and vitamin E. They are also an excellent source of manganese and copper — minerals we rarely get in sufficient amounts.
B vitamins are essential for the nervous system, energy metabolism, and red blood cell production. Hazelnuts also contain proanthocyanidins — antioxidants that strengthen blood vessel walls. Thanks to their low glycemic index, they are an excellent choice for people with diabetes.
Tip: Hazelnuts grow abundantly across European latitudes and can be soaked like almonds for better nutrient absorption.
4. Cashews — A Mineral Powerhouse of Iron and Zinc
Cashews are remarkably rich in iron, zinc, magnesium, and copper. A 30-gram serving provides approximately 1.9 mg of iron and 1.6 mg of zinc, making them one of the most valuable nuts for people at risk of anemia. Iron is essential for oxygen transport in the blood and for preventing fatigue.
Zinc supports the immune system, aids wound healing, and is critical for reproductive health. Magnesium relaxes muscles, promotes sleep quality, and regulates blood pressure. Cashews also contain tryptophan — an amino acid and precursor to serotonin — making them a natural mood booster.
5. Pistachios — The Protein Nut with Antioxidants
Pistachios are one of the most protein-rich nut varieties — about 6 grams of protein per 30-gram serving. They are also an exceptional source of lutein, zeaxanthin, and vitamin B6. Lutein and zeaxanthin are carotenoids that accumulate in the retina and protect the eyes from blue light damage and age-related macular degeneration. Vitamin B6 is involved in over 100 enzymatic reactions in the body, including the production of neurotransmitters.
Pistachios also have the lowest calorie content among nuts, making them ideal for maintaining a healthy weight. Their high fiber content supports the gut microbiome.
Tip: Choose unsalted pistachios in their shells — the shelling process slows down eating and helps with portion control.
6. Macadamia — The Queen of Monounsaturated Fats
Macadamia earns its title as the “queen of nuts” — it contains the highest percentage of monounsaturated fatty acids among all nuts, about 75% of total fat. It is also a rare dietary source of palmitoleic acid (omega-7). Monounsaturated fats lower LDL cholesterol without affecting HDL (good) cholesterol, significantly reducing the risk of atherosclerosis. Omega-7, rarely found in foods, strengthens blood vessel walls and improves insulin sensitivity.
Macadamia also contains flavonoids with antioxidant properties that support brain function and protect neurons from oxidative stress. Its high manganese content supports bone tissue formation.
7. Brazil Nuts — The Ultimate Selenium Source
Brazil nuts are the richest natural source of selenium on the planet. Just one Brazil nut provides 70–90 micrograms of selenium — more than the entire daily recommended intake of 55 mcg for adults. Selenium is critically important for proper thyroid function — it participates in the conversion of thyroxine (T4) into the active hormone triiodothyronine (T3).
It is also a powerful antioxidant that protects cells from oxidative damage. Selenium supports immune response and has been linked to a reduced risk of certain cancers. Brazil nuts also contain ellagic acid — a polyphenol with anti-inflammatory and cardioprotective properties.
Tip: Due to their extremely high selenium content, 1–2 Brazil nuts per day are perfectly sufficient. Excessive consumption can lead to selenosis.
8. Apricot Kernels — The Traditional Source of Vitamin B17
Apricot kernels are less commonly used but hold a special place in folk medicine. They contain vitamins B15 and B17 (amygdalin), vitamin E, iron, and phosphorus. Amygdalin, also known as vitamin B17, is used in alternative medicine for its immune-stimulating properties.
Apricot kernels also have a cleansing effect, supporting the liver and toxin elimination. Vitamin E and the antioxidants they contain contribute to skin health.
Important: Apricot kernels contain amygdalin, which breaks down into cyanide in the body. In large quantities, this can be dangerous. Consume no more than 1–2 kernels per day. Children and pregnant women should avoid consumption without medical advice.
Nut Allergies — Alternatives with Similar Benefits
People with nut allergies can usually safely consume seeds that deliver many of the same nutritional benefits of nuts: chia seeds for omega-3, flaxseeds for fiber and lignans, hemp seeds for complete plant protein, pumpkin seeds for zinc and magnesium, and sunflower seeds for vitamin E and selenium. If you have an allergy, consult your doctor before introducing new foods.
How Many Nuts Should You Eat Per Day?
One handful — approximately 30 grams — is the widely recommended daily amount. This is enough to enjoy the full benefits of nuts without excessive calorie intake. Eat them raw or lightly roasted, without added salt or coatings. Avoid heavily processed nuts — extra salt and sugar glazes can negate their health properties and increase the risk of chronic disease. Variety is key: rotate different types throughout the week so your body benefits from each nut’s unique nutritional profile.
