Omega-3 and nervous system, benefits for development and old age are real

Brain: great benefits in old age thanks to Omega 3 supplements

The action carried out by Omega 3 on the nervous system is crucial for its development and maintenance of cognitive abilities during old age. The confirmation comes from the pages of Nutritional Neuroscience, which published a comprehensive analysis of the results obtained in the course of various researches, carried out by psychologists at Western Oregon University in Monmouth (United States). According to the authors, further studies will allow clarifying the role played by these fatty acids also during childhood, youth and adult life.

The importance of proper nutrition for the brain

For the brain to function to the best of its ability, it is important to feed it properly. In fact, this organ consumes 20 percent of the calories introduced with food each day. The most important nutrient is glucose, which ensures the maintenance of vital functions, such as respiration, and cognitive activities. However, it is important that all macronutrients, i.e., sugars, fats, and proteins, are introduced in adequate amounts.

Fats yes, but which ones?

That one fat is not worth the other is a truth that affects the whole organism, including the brain. For example, fast food foods containing fats are extremely harmful to health. Saturated fats, on the other hand, take a long time to be metabolized. In contrast, so-called unsaturated fatty acids can exert significant benefits on the body, including nerve tissue. Omega-3s belong precisely to this class of fats. Several studies have shown that those who consume large amounts of saturated fats run a greater risk of developing cognitive deficits and incurring a stroke. Omega-3s, on the other hand, can counteract disorders such as depression and schizophrenia, and are also important for fetal brain development.

Omega-3, different effects according to age

The analysis carried out by U.S. psychologists clarified the different role of Omega-3 at different stages of life. In particular, comparing the results of different research in the scientific literature, the scholars concluded that taking Omega-3 in gestation positively influences the development of the nervous system. This effect seems to diminish after birth, and although some studies indicate a positive effect on cognitive abilities during childhood, youth and middle age, the data collected do not allow for definitive conclusions in this regard. Instead, much research has shown that Omega-3 intake in later life protects against neurodegeneration and may reduce the likelihood of developing cognitive disorders. Further research will verify the benefits exerted by these fatty acids on cognitive abilities in the middle stages of life.
