There are many reasons why we ought to eat healthy food. The main reason is so our cells can absorb the nutrients they need to carry out their functions. Vitamin C, which is found in several types of fruit and vegetables, is needed for a strong immune system, cell regrowth and resiliency, for eliminating free-radicals. Protein, found in animal products and legumes, is needed for energy and muscle regrowth. Vitamin A, found certain fruits and vegetables, is needed for cell regeneration. B vitamins, found in legumes and certain fruits, are responsible for regulating metabolism and the nervous system. Vitamin D, found in certain fish and eggs, is responsible for calcium absorption. These are just a few examples of nutrients you get from your diet. If you do not eat foods that contain these nutrients, you are at risk of having a deficiency. Vitamin deficiencies lead to serious health problems such as severe joint pain, digestion problems, rickets, scurvy, osteoporosis, cancer, and heart disease.
The other major reason we need to eat healthy foods is to maintain a healthy weight. Processed foods, such as fast food or pre-packaged food, lack nutrients. Processed food does not provide the amount of nutrients that healthy food contains. It is more difficult for a person to feel full after eating processed food. This leads to overeating and poor nutrition. If a person continually eats nothing but processed food, they could easily develop a nutrient deficiency. Fast food and manufactured food is created with ingredients that have nutrients taken out. For example, if the whole part of a wheat kernel is used in a recipe, it will contain a high amount of fibre. Processed food is normally created with wheat without the parts that contain fibre. Nutrients that would normally exist in the ingredients are literally depleted when processed food and fast food is made.
