Nuts can sometimes be classified as unhealthy food if they are processed: fried, salted, or soaked in chocolate. However, when consumed raw and unprocessed, they are a garden of health. A study published in the American Journal of Clinical Nutrition proved that the intake of nuts must not be limited.
Namely, people who consume nuts on a daily basis or as a replacement for another food can lose more weight and have a smaller waist. Even though this is not a significant loss of weight and decrease of the waist circumference, results have shown that nuts do not add to weight gain and are excellent for a healthy blood system. Moreover, nuts are rich in alpha-linolenic acid so they protect the heart in times of great stress which can lead to weakened immunity. By consuming almonds rich in vitamin E, group B vitamins, and magnesium, your immunity will not weaken.
Almonds, peanuts, hazelnuts, cashew nuts, and Brazil nuts play an important role in decreasing the risk of developing cardiovascular diseases, according to a study conducted at Harvard. This is due to the fact that nuts can lower the LDL cholesterol and they have healthy monounsaturated and polyunsaturated fats, i.e. fibers which protect the heart. Nuts are rich in arginine- an amino acid which relaxes the blood vessels. A diet rich in pistachios can prevent the occurrence of lung cancer to some extent, according to a preliminary research presented at Cancer Prevention Research Conference. Scientists consider that the key role is played by the Gamma E Tocopherol.
A study from 2010, published in the Archives of Internal Medicine showed that everyday consumption of one cup of nuts lowers bad LDL cholesterol for 7, 4%. Additionally, triglycerides concentration is decreased for more than 10%. Brazil nuts are rich in selenium and can help with advanced prostate cancer, according to a study conducted in Netherlands. Namely, men who had high levels of selenium in their blood had 60% lesser chance of developing advanced prostate cancer stage 17 years later.
Since nuts have a healthy amount of vitamin E in them, they are considered as food for the brain because they prevent the cognitive impairment that comes with age. The most recommended nuts are peanuts since they contain an abundance of group B vitamins. Two handfuls of nuts per day also improve the semen quality- the vitality, mobility, and morphology, according to a UCLA study.
