Why are our senses important and how does a good nutrition affects them please respond in a paragraph
Brums [2.3K]

Answer: Your senses are important because they work together to let your brain know what is going on around you. And they help to keep you safe by warning you of any danger. The way food looks not only entices you it actually affects they way you fell & act. For example diets high in refined sugars, for example, are harmful to the brain. In addition to worsening your body’s regulation of insulin, they also promote inflammation and oxidative stress. Multiple studies have found a correlation between a diet high in refined sugars and impaired brain function — and even a worsening of symptoms of mood disorders, such as depression.
