HOW MISSING NUTRIENTS AFFECT YOUR BODY

HOW MISSING NUTRIENTS AFFECT YOUR BODY

Nutrition not only affects your body’s ability to maintain itself but also helps you manage your risk for developing a disease. An occasional lapse in eating foods of high nutritional quality is unlikely to cause problems, but consuming low-quality foods, especially when practiced over time, can impact both your short-term and long-term well-being.

HERE IS A SUMMARY HOW MISSING NUTRIENTS AFFECT YOUR BODY

Getting those missing nutrients through diet

Experts agree that the best way to get the nutrients we need is through food. A balanced diet — one containing plenty of fruits, vegetables, and whole grains — offers a mix of vitamins, minerals, and other nutrients (some yet to be identified) that collectively meet the body's needs. Maybe what counts is the synergistic interactions of these nutrients — which might also help explain why trials of single nutrients often don't pan out.

Still, there are some reasons for certain people to take vitamins.

Women should take 400 micrograms of folic acid a day during their childbearing years. This is the amount in standard multiple vitamins. Taking in enough folic acid helps prevent pregnant women from having a baby born with spina bifida.

Also, people that aren't exposed to sunlight too often — which can cause a lack of vitamin D — may benefit from a multivitamin. We need sunlight to change the inactive form of vitamin D in our skin to the active form. Most people in the upper half of the northern hemisphere don't get enough sunlight during winter and most of spring and fall as well. Also, we have been told to avoid sunlight because it ages our skin and causes some types of skin cancers.

Here's another reason to take multivitamins: it may help slow down macular degeneration. This eye disease is seen mainly in older people. But it's not clear whether vitamins actually prevent the disease.

Strict vegetarians should take vitamin B₁₂. They may also need an iron supplement.

The doses in standard multivitamins are safe. If your diet has too little of any vitamin or mineral, multivitamins are still a very low-cost way to protect yourself against vitamin deficiencies.
