Omega-3 and the nervous system, benefits for development and old age are real
Brain: great benefits in old age thanks to Omega 3 supplements
The action of Omega 3 on the nervous system is fundamental for its development and the maintenance of cognitive abilities during old age. Confirmation comes from the pages of Nutritional Neuroscience, which published a global analysis of results obtained from various studies, conducted by psychologists at Western Oregon University in Monmouth (United States). According to the authors, further studies will clarify the role played by these fatty acids also during childhood, youth, and adulthood.
The importance of proper nutrition for the brain
For the brain to function at its best, it is important to feed it properly. This organ consumes 20% of the calories introduced daily with food. The most important nutrient is glucose, which guarantees the maintenance of vital functions, such as breathing, 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 not all fats are equal is a truth that concerns the entire body, including the brain. Fast food foods, for example, contain fats that are extremely harmful to health. Saturated fats, instead, take a long time to be metabolized. On the other hand, the so-called unsaturated fatty acids can exert significant benefits on the body, including nervous tissue. Omega-3 belong precisely to this class of fats. Several studies have shown that those who consume large amounts of saturated fats run a higher risk of developing cognitive deficits and suffering a stroke. Omega-3s, on the other hand, can counteract disorders such as depression and schizophrenia, and are also important for the development of the fetal brain.
Omega-3, different effects depending on age
The analysis carried out by the American psychologists clarified the different role of Omega-3s at various stages of life. In particular, by comparing the results of different studies in the scientific literature, the researchers concluded that taking Omega-3 during pregnancy positively influences the development of the nervous system. This effect seems to weaken after birth, and although some studies indicate a positive action on cognitive abilities during childhood, youth, and middle age, the data collected do not allow definitive conclusions on this. Many studies have instead shown that taking Omega-3 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 central phases of life.
