Vitamins are Needed for a Healthy Body
Vitamins are known as a micro-nutrient as we only need little amounts in our diet. In order to consume enough vitamins and minerals it is crucial that you eat a wide variety of foods like fuits, vegetables, grains, and meats every day.
Here is a list of several vitamins on what they do for our bodies.
Vitamin A: (Beta carotene) Essential for good vision, healthy skin, hair, teeth and bones; can also boost immune function and help protect against cancer. Recommended amount: 10,000 IU per day.
B Vitamins, including Folic Acid: Folic Acid, B6 and B12 work together to prevent anemia, manufacture red blood cells and build genetic material. Folic Acid also has been proven to reduce the risk of birth defects. The latest research also shows that these B vitamins may improve memory and reduce levels of homocysteine (a chemical found in the blood that may help predict heart attack and stroke risk), thereby lowering your risk of heart disease and stroke. Folic Acid is also being studied as a means to ward off colon and breast cancers. Recommended amount: Folic Acid 0.4 mg. per day, B6 (pyridoxine) 50 mg. per day; B12 300mcg. Per day (micrograms).
Vitamin C: Helps prevent heart disease and cancer. Contributes to wound healing, immune functions, the production of collagen (connective tissue) and healthy gums. It also helps the body absorb iron. Recommended amount: 500 mg. per day
Vitamin D: Maintains healthy bones (by helping your body to absorb calcium) and promotes immune function; may help protect against the loss of lean muscle mass associated with aging. New research suggests it may also protect against breast and colon cancers. Recommended amount: 400 IU per day
Vitamin E: Helps form red blood cells, muscle and other tissues. In large quantities, it may protect against cancer causing cell changes, reduce your risk of heart disease and enhance immune function. New research indicates that E also may slow the progression of Alzheimer’s disease and be a useful therapy for diabetes (it improves glucose control) and arthritis (it reduces inflammation). Recommended amount: 400 IU per day. Do not exceed 400 IU per day without the advice of your doctor.
Folic Acid: Take 0.4 mg daily when trying to get pregnant as this prevents some birth defects.
Important Minerals for Everyone
As with vitamins, it can be difficult, to get the amounts of minerals needed for optimum health through diet alone. Mineral supplements can help you make sure you are getting all the minerals your body requires. Below is a list of essential minerals we recommend.
Calcium: Calcium is vital for the formation of strong bones and teeth and for the maintenance of healthy gums. It is also important in the maintenance of a regular heartbeat and the transmission of nerve impulses. Calcium lowers cholesterol levels and helps prevent cardiovascular disease. It may increase the rate of bone growth and bone mineral density and children. It may lower blood pressure and prevent bone loss associated with osteoporosis as well. RDA: 1000 mg. per day, 1500 mg. per day after menopause.
Magnesium: Magnesium assists in calcium and potassium uptake. Supplementing the diet with magnesium can help prevent depression, dizziness, muscle weakness and twitching, and premenstrual syndrome, and also aids in maintaining the body’s proper pH balance. Recommended amount: 750 mg. per day. Potassium Role: This mineral is important for a healthy nervous system and a regular heart rhythm. It helps prevent stroke, aids in proper muscle contraction and works with sodium to control the body’s water balance.
Selenium: Selenium’s primary function is to prohibit the oxidation of lipids (fats). A vital antioxidant, especially when combined with vitamin E. It protects the immune system by preventing the formation of free radicals, which can damage the body. It has also been found to function as a preventive against the formation of certain types of tumors. Selenium and vitamin E act synergistically to aid in the production of antibodies and to help maintain a healthy heart and liver. This trace element is needed for pancreatic function and tissue elasticity. Recommended amount: 200 mcg. (micrograms) per day
Potassium: Important for chemical reactions within the cells and aids in maintaining stable blood pressure. Recommended amount: 50 mg. per day
Iron: Perhaps the most important of irons functions in the body is the production of hemoglobin and myoglobin and the oxygenation of red blood cells. Iron is the mineral found in the largest amounts of the blood. It is essential for many enzymes, including catalase, and is important for growth. Iron is also required for a healthy immune system and for energy production. Recommended amount: 30 mg. per day (if you take a supplement, this can cause black-looking feces and constipation).
Minerals play several roles in our bodies
Here is a list of some of the most important minerals we need in our diet and what they do for us.
Calcium: Important for healthy bones and teeth. Found in dairy produce, leafy green vegetables, bread, tap water in hard water areas, nuts and seeds (especially sesame seeds), dried fruits, cheese. Vitamin D helps calcium to be absorbed.
Iron: Needed for red blood cells. Found in leafy green vegetables, whole meal bread, molasses, eggs, dried fruits (especially apricots and figs), lentils and pulses. Vegetable sources of iron are not as easily absorbed as animal sources, but a good intake of vitamin C will enhance absorption.
Zinc: Plays a major role in many enzyme reactions and the immune system. Found in green vegetables, cheese, sesame and pumpkin seeds, lentils and wholegrain cereals.
Iodine: Present in vegetables, but the quantity depends on how rich the soil is in iodine. Dairy products also have plenty of iodine. Sea vegetables are a good source of iodine for vegans.
Vitamins for Weight loss
The body’s weight-control or weight-related functions - like appetite, hunger, metabolic rate, metabolism of fats and sugars, calorie-burning, and so on - operate more efficiently with an optimum intake of vitamins. All of them play a part in maintaining optimum health and weight, and many operate together, so it’s not really accurate to single out certain vitamins as being “best” for weight loss. That said, certain vitamins are worth a special mention.
The most important vitamins and minerals for weight loss are: Vitamin B2, Vitamin B3, Vitamin B5, Vitamin B6, Choline (part of B-complex), Inositol (part of B-complex), and Vitamin C.
It is very important to remember that cooking foods at high temperatures may reduce the vitamin and mineral content in the foods.
Vitamins and minerals play a very important role with a balance diet, healthy living, and weight loss. Make sure you take it into consideration the amount of these micro-nutrients you consume as they can make healthy living more enjoyable than ever.
