The brain is like a computer that controls the functions of the body and the nervous system, a network that sends messages to the parts of the body, according to the educational portal KidsHealth.
In addition, the US National Library of Medicine MedlinePlus explained that the brain is made up of more than a billion neurons. Some specific groups of them work together to give the ability to reason, experience feelings and understand the world. They also help remember varying amounts of information.
For its part, the immune system is the body’s defense against infectious organisms and other invaders, according to Rady Children’s Hospital-San Diego.
The immune system defends the body against substances it considers harmful or foreign, known as antigens. These can be germs like bacteria and viruses, chemicals or toxins, cells damaged by cancer, or sunburn.
The immune system then remembers the antigen. If it recognizes it again, it can quickly identify it and send the correct antibodies. Thanks to this, in most cases people do not get sick. This protection against a certain disease is known as immunity.
Having said the above, both the brain and the immune system must be protected and to do so you must have a balanced and healthy diet which contains fats, proteins, carbohydrates, fruits and vegetables and also nuts such as walnuts, because according to The Vanguard this is a super food that is “rich in vitamins, minerals and antioxidants”.
In addition, the media cited a study by Dr. Marta Guasch that states that “many scientific studies, including observational and intervention studies, have shown that consuming walnuts, and also other nuts, can help prevent heart disease through mechanisms such as improvement of the lipid profile, that is cholesterol, and for its antioxidant and anti-inflammatory properties”.
Additionally, according to the portal Very interesting, Research conducted by neuroscientists at Boston University in the United States has shown that adding walnuts to the daily diet improves the performance of activities that require motor or behavioral skills in the elderlysince the connection between neurons is facilitated because they are fruits rich in polyphenols and other antioxidants.
Similarly, shares the portal, a study published in the journal Neurochemical Research affirms that the walnut extract, that is, when the fiber is eliminated, helps to mitigate the effects of oxidative stress and cell death that are generated in the brain of people with Alzheimer’s. This agrees with an investigation carried out by Rush University Medical Center in Chicago, cited by Business Insider, which indicates that the vitamin E present in nuts helps prevent Alzheimer’s disease.
What is the right amount of nuts per day?
Although they have several good properties for health, it should not be forgotten that 80% of walnuts are fat and therefore their consumption must be measured. Experts recommend eating a handful of nuts or, failing that, one or two tablespoons of walnut paste to replace other saturated fats, such as those found in eggs, dairy products, and meats.
Also, according to the American Heart Association (AHA), advises eating four servings of unsalted nuts during the week. A trick is to choose the most raw or roasted and avoid nuts cooked in oil.
Without a doubt, walnuts are an excellent complement to a balanced diet. However, its intake must always be accompanied by other healthy practices to maintain the good condition of the body, and according to the World Health Organization (WHO), the exact composition of a varied, balanced and healthy diet will be determined by the characteristics of each person (age, sex, life habits and degree of physical activity), the cultural context, the food available in the place and eating habits.
