Vitamins assist the enzymes that release energy from carbohydrates, proteins and fats, but they do not provide energy themselves, unlike protein, carbohydrates and fats, vitamins do not yield usable energy when broken down.
Vitamins are natural organic substances essential for the proper regulation of reproduction, growth, health, and energy production. Humans are unable to manufacture most of the necessary vitamins and these must be obtained from dietary sources, either as whole foods or supplements.Though its essential to get vitamins from food. Supplements should be taken in addition to meals and with meals for their essential and proper absorption.
There are 13 vitamins, 16 minerals, and one additional dietary component that your body needs but cannot manufacture in sufficient amounts. Acting in concert, these essential vitamins and minerals help keep billions of cells healthy and encourage them to grow and reproduce. Some supply the keys to unlocking the energy in the carbohydrate, fat, and protein in the foods you eat. These essentials are often called micronutrients because your body needs only tiny amounts of them. Yet failing to get even those small quantities virtually guarantees disease. Old-time sailors learned that living for months without fresh fruits or vegetables the main sources of vitamin C causes the bleeding gums and listlessness of scurvy. In some developing countries, people still become blind from vitamin A deficiency. And even in the United States, some children develop the soft, deformed bones of rickets because they don’t get enough vitamin D.
While the absence of key micronutrients hampers good health, their presence in sufficient quantities promotes it. Getting a full complement of iron helps proteins in your blood and muscles pick up and release the oxygen that’s vital to all of your cells. It also fends off the absorption of lead, a heavy metal that can cause widespread damage. The B vitamin folic acid can be a powerful agent in protecting against birth defects and may help ward off heart disease and some forms of cancer. And a combination of calcium, vitamin D, vitamin K, magnesium, and phosphorus protects your bones against fractures.
Many of these micronutrients interact with one another. Vitamin D enables your body to pluck calcium from food sources passing through your digestive tract. Vitamin C helps you absorb iron. Vitamins and minerals differ in basic ways. Vitamins can be broken down by heat, air, or acid. Minerals are chemical elements that do not change. That means the minerals in soil and water easily find their way into your body through the plants, fish, animals, and fluids you consume. But it’s tougher to shuttle vitamins from food and other sources into your body because cooking, storage, and simple exposure to air can inactivate these more fragile nutrients.
Vitamins and minerals are widely available from the natural foods we eat. So, before you reach for the vitamin jar, try eating your vitamins from natural foods. Here are some of the best sources for each:
