Your body needs essential nutrients to function properly and stay healthy. These nutrients must be obtained from the food you eat; your body cannot produce them on its own. The six essential nutrients are vitamins, minerals, proteins, fats, water and carbohydrates. Micronutrients are made up of vitamins and minerals, and although the body only needs small amounts of them, a deficiency can cause health problems.
In general, a person who follows a diet rich in vegetables, fruits, and lean proteins can get all the vitamins they need in their food. However, people who eat less fruit and vegetables and people with digestive problems may need to take a vitamin supplement to reduce or avoid a deficiency. Vitamins are essential to human health and each of the 13 vitamins has its own benefits. Examples of simple sugars include sucrose, the type of sugar you would have in a bowl at the breakfast table, and glucose, the type of sugar that circulates in your blood.
Whole grains and fruits are full of fiber, which reduces the risk of coronary heart disease and helps maintain normal blood glucose levels. Water is essential to life and the body needs it to perform a number of functions, such as digestion, absorption, maintaining electrolyte balance and eliminating unused nutrients and toxins from the body through urination and perspiration. Potassium maintains the volume of fluid in and out of cells and prevents excessive increases in blood pressure with increased sodium intake.These six essential nutrients are necessary for the body to function properly. They help maintain fluid balance, build bone tissue, synthesize hormones, transmit nerve impulses, contract and relax muscles, and protect against harmful free radicals in the body that can cause health problems such as cancer.
