Why You Should Eat More Nuts

Why You Should Eat More Nuts

If you are among those who avoid nuts because of their high fat content, it's time to change your mind. During the last 10 years, scientific studies have debunked the popular belief that nuts raise cholesterol and lead to obesity. Now, they are highly recommended due to their amount of unsaturated fats and multiple essential nutrients. One important thing about nuts is that they make you feel satisfied with small portions, and eating them as a snack will keep you away from other much more caloric temptations.

1. Pecans

Pecans are among the most nourishing nuts, outshined only by macadamia nuts. They have more than 19 vitamins and minerals, such as vitamin A, vitamin E, calcium, magnesium, phosphorus, potassium, several B vitamins, and zinc. Pecans help lower cholesterol levels, but they also have an important neurological impact, delaying neurodegeneration and improving motor function, which makes them an ideal antioxidant, anti-aging food, great in the prevention of diseases like amyotrophic lateral sclerosis (ALS), Alzheimer's, and Parkinson's disease.

2. Walnuts

Walnuts are the only type of nut that offers large doses of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid. One single ounce of walnuts a day delivers more than 100% of the suggested dose for an adult. According to scientific research, a diet high in ALA effectively protects your bones. Thanks to their ALA content and phenols, walnuts may have more anti-inflammatory qualities than other nuts. In addition, they have zero saturated fat or sodium, which makes them a great option to regulate cholesterol levels.

Additionally, walnuts' elevated content of polyunsaturated fatty acids (PUFAs) may help in preventing arterial obstruction. A study has shown that adding walnuts to a healthy diet improves vasodilatation in type 2 diabetic patients, suggesting a potential reduction in overall cardiac risk.

3. Brazil Nuts

Brazil nuts are among the most caloric nuts. However, they have plenty of nutrients and offer important health benefits. In spite of a low content of protein and vitamins (mainly folic acid and choline), Brazil nuts are especially charged with selenium, a trace mineral that isn't produced by the body and needs to be ingested in small doses through food.

Selenium influences hormonal activity and neurotransmitters in the brain, affecting moods in humans and behavior in animals. Moderate consumption of selenium not only defuses the neurotoxicity of metals, but also helps prevent loss of brain function caused by aging. A study concluded that the daily intake of two Brazil nuts is enough to increase selenium levels.

4. Almonds

Almonds are among the less caloric nuts and show high levels of protein as well as antioxidants, especially vitamin E. Because of their unique composition, almonds are likely to significantly reduce cardiovascular and diabetes risks, such as being overweight, glucose homeostasis, inflammation, and oxidative stress. Eating almonds will also increase your levels of magnesium, a mineral that plays a key role in producing energy, controlling muscle contractions, and building stronger bones.

5. Cashews

Cashews are highly nutritious and provide a substantial amount of energy. These delicious nuts have a high content of unsaturated fats, dietary fiber, and plant-based proteins. They also have vitamins that are essential for the body. Cashews' mono- and polyunsaturated fats significantly decrease cholesterol levels, as well as reduce the risk of cardiovascular disease, stroke, metabolic syndrome, and diabetes.

Most nuts are easy to find and can be eaten raw as a snack or as an addition to salads, main courses, and desserts. As a part of a healthy diet, nuts can provide lots of energy. Munch on some nuts during the day and you will see an overall improvement in no time at all.
