Nuts as nutrient-rich snacks
Nuts, which are considered a quick and tasty snack, are gaining popularity among various social groups. Interest in nuts has grown not only because of their taste but also due to their high nutritional value. Nuts are rich in B vitamins, vitamin E, and mineral ingredients. The composition of nuts includes calcium, which plays a significant role in bone formation and proper functioning of the nervous system; iron, a component of hemoglobin, and essential for the transport of oxygen to all body cells; phosphorus, a constituent of ATP molecules and nucleic acid; and magnesium, which performs various functions in the human body, including participation in protein synthesis, involvement in nerve conduction, and muscle contraction. The content of valuable nutrients in nuts largely depends on the variety of nuts and the form in which we consume them. Unfortunately, nuts are often subjected to caramelization or salting, which limits their nutritional value.
Required level of unsaturated fatty acids
Cardiovascular diseases, including lipid disorders, are frequently occurring conditions, especially in countries with a high level of development. If left untreated, they can be fatal. The development of cardiovascular diseases is influenced by factors such as high cholesterol and triglyceride levels, oxidative stress, and inflammation. However, consuming nuts, which are a source of unsaturated fatty acids, is beneficial for the lipid profile and lowers the total cholesterol, LDL cholesterol, and triglyceride levels. Additionally, it reduces blood pressure, decreases blood clotting, and prevents the formation of blood clots and heart attacks. Particularly, according to scientific research, walnuts are notable in the prevention of cardiovascular diseases, which everyone should consume, but in appropriate amounts.
Diverse selection
An abundant assortment of nuts includes almonds, kidney nuts, walnuts, plums, pistachios, peanuts, pecans, macadamia nuts, Brazil nuts, pine nuts, and coconuts. Each of these varieties is valuable in its composition and worth trying to diversify our diet.
Nuts in a reduction diet
If we are battling with excess weight and are reducing our calorie intake, then we should refrain from excluding nuts from our diet. Indeed, they provide a substantial amount of energy, averaging 553-718 kcal per 100 grams of nuts, they are also rich in fats, however, we must not forget that these are mainly unsaturated fatty acids that we should not give up. The carbohydrate content in nuts is usually low, although in kidney or pistachio, this significantly increases and amounts to about 30%. Additionally, the consumption of nuts due to the content of NNKT exerts a positive impact on our metabolism. Nuts also contain fiber, which is particularly important for those looking to shed excess weight, as it induces a desire for a filling meal. Especially on a reduction diet, we should pay attention to how much we consume of these nuts, despite their beneficial effects, they are high-energy products, therefore, we cannot eat them without restrictions, we must control their amount in our diet.
A source of protein and antioxidant compounds
Nuts are predominantly a source of fat in our diet, but it's worth remembering that they're also an excellent source of protein and antioxidant compounds. It's worth noting that the protein content of nuts is around 20%. The highest protein content is found in almonds, pistachios, and peanuts. Comparatively, walnuts and hazelnuts have a relatively lower protein content. Due to their protein content, nuts can be a very advantageous alternative in the daily diet for vegans and vegetarians. Foods rich in antioxidant compounds play a crucial role in preventing many diseases. Research has shown that walnuts contain the highest amount of antioxidant compounds, particularly tannins. Therefore, walnuts with a high content of tannins have the best antioxidant effect among nuts.
