Nuts have held an important place in daily life for centuries as a highly nutritious and easily consumable snack. With the rise of healthy eating trends in recent years, the health benefits of nut consumption have become increasingly prominent. While these natural foods offer a range of positive effects, they may also have certain potential drawbacks.
What are the benefits of nuts?
Nuts, rich in omega-3 and unsaturated fatty acids, play a significant role in supporting cardiovascular health. Powerful antioxidants such as vitamin E, zinc, and selenium strengthen the immune system, protecting the body against the harmful effects of free radicals.
Vitamin B and magnesium contribute to improved brain function, enhancing cognitive performance. Their high fiber content aids in the proper functioning of the digestive system and supports glycemic control by helping regulate blood sugar levels. Minerals such as magnesium and potassium provide natural energy, while calcium and phosphorus help maintain strong bones. Nuts also have a positive impact on skin and hair health.

What are the harms of nuts?
Although nuts are generally considered healthy foods, excessive consumption can lead to certain health concerns. Certain varieties, such as peanuts and hazelnuts, are among the most potent allergens and may cause allergic reactions. Due to their high calorie content, they may contribute to weight gain if portion control is not maintained.
Salted nuts, with their high sodium content, may increase the risk of hypertension. Products containing additives may carry harmful chemicals. Roasted nuts left exposed for long periods can develop oxidized fats, which may negatively impact heart health. In some shell varieties, environmental contamination may result in the presence of heavy metal residues.

Recommended Daily Nut Consumption
The American Heart Association, in its lifestyle management guidelines for reducing cardiovascular risk, recommends that a diet averaging 2,000 kcal/day should include 4–5 servings of nuts per week, with each serving containing 28.3–42.4 grams of seeds or nuts. Similarly, the Academy of Nutrition and Dietetics emphasizes that incorporating a daily handful of unsalted raw nuts into the diet can significantly contribute to lowering the risk of cardiovascular diseases.
A single serving, equivalent to approximately 30 grams, may correspond to 4–5 large walnuts, 27–30 peanuts, 24–26 almonds, 28–30 hazelnuts, 1 cup (60 g) sunflower seeds, or ½ cup (40 g) pumpkin seeds.Additionally, these portion sizes are also considered ideal measurements for various nut consumption areas, ranging from desserts and salads to breakfast blends and energy bars.
