Vitaminas

What are vitamins and how do they work?

Vitamins are organic compounds that are needed in small amounts to maintain life. Most vitamins must come from food.

This is because the human body either doesn't make enough or doesn't make any.

Each body has different needs for vitamins. For example, humans need to consume vitamin C or ascorbic acid, but dogs do not. Dogs can produce, or synthesize, enough vitamin C for their own needs, but humans cannot.

People need to get most of their vitamin D from exposure to sunlight, because it is not available in large enough amounts in food. However, the human body can synthesize it when exposed to sunlight.

Different vitamins have different functions and are needed in different amounts.

Can vitamins and minerals compensate for a poor diet?

Healthy foods provide us with nutrients in a balanced and complete way so that our body can absorb them. Nutritional needs must be met primarily with food. People should try to meet their nutrient needs through healthy eating patterns that include nutrient-dense foods that contain vitamins, minerals, dietary fiber, and other natural substances that have positive health effects.

Food supplements such as vitamins can provide excessive or insufficient amounts of some nutrients. The reality is that a pill can never replace the benefits of a diet that includes some fruit and lots of fresh vegetables and some high-quality meat, eggs, fish, dairy, and fat. For more information on healthy eating, you should consult your doctor.

Who needs to take vitamins in supplement form?

Most of us can get everything we need from diet; however, there are specific situations in which a supplement may be beneficial:

During the childbearing years, it is recommended that women who are or may become pregnant take a folic acid supplement, eat foods fortified with folic acid, or both. This is important to reduce the risk of certain birth defects, which often occur before a woman knows she is pregnant. Prenatal vitamins contain folic acid. Look for brands with methyl folate, a more absorbable form of folate.

Pregnant women and teenage girls are at a higher risk of iron deficiency anemia. A simple blood test can diagnose this condition, which is reversible with dietary changes or an iron supplement.

Older people, nursing babies, and people with dark skin may need vitamin D supplements. People with liver disease, cystic fibrosis, celiac disease, and Crohn's disease may also need it. Finally, those who are obese or who have undergone gastric bypass surgery may need additional vitamin D. Since the northern countries lack sunlight during the winter it can be difficult to obtain adequate amounts of vitamin D, many doctors perform a blood test to help determine if a vitamin D supplement is necessary.

People with multiple food allergies or a vegan diet may benefit from a multivitamin / multimineral. For example, vegans should supplement with vitamin B12 because animal foods are the main dietary source of this essential nutrient.

Older people can benefit from taking vitamin B12 and vitamin D, which become more difficult to obtain in adequate amounts from food as we age.

People who consume very restrictive, low-calorie diets due to poor appetite, drug and alcohol use, or an eating disorder may need supplements to reduce the risk of nutrient deficiencies and malnutrition.

Bariatric surgery can affect your ability to absorb some nutrients, increasing the risk of malnutrition. Your doctor will work with you to ensure good nutritional status after surgery.
