VITAMINS are nature’s health ingredients in food and drinks. You may remember your primary school teacher telling you about the importance of vitamins and what they do for your body.
When you make food choices during a meal, do you actually give any thought about what vitamins the food contains?
Like most people, it’s probably the furthest from your mind. Sadly, most adults make food choices based on taste.
Being a mindful eater is about being clued in on what food gives your body the proper nourishment.
WHAT ARE VITAMINS
Vitamins are organic compounds that are complex in structure and is part of the physiological processes in your body. The only way we get vitamins is by eating something.
We must eat a variety of food to ensure we get sufficient vitamins as the body cannot make enough vitamins to maintain proper health.
When the body lacks vitamins, the resulting deficiency will manifest in various symptoms and lead to poor health. Once the deficiency is addressed and the person gets sufficient amounts of the vitamin they are lacking, good health will be restored again.
Deficiencies are usually treated by making sure the person eats enough servings of foods that are rich in a particular nutrient, or by giving a standard dosage of supplements. Vitamin supplements are synthetic versions of natural vitamins.
WATER- AND FAT-SOLUBLE VITAMINS
Vitamins are either water-soluble or fat-soluble. Vitamins A, D, E and K are fat-soluble. They are present in the lipids or the fatty part of a particular food. All other types of vitamins are water soluble. This means they dissolve in water.
Fat-soluble vitamins are harder for the body to get rid-off. If you consume extremely high doses of fat-soluble vitamins, such as vitamin A, it can cause toxicity in the body. This is because the body stores it in fat and the liver.
Excess water soluble vitamins, on the other hand, are excreted in urine as the body only stores what it needs. So the chances of toxicity from water soluble vitamins is rare.
VITAMIN SOURCES
You can get your daily vitamin needs from the five food groups - meat, grain, vegetable, fruit, dairy and even good bacteria.
That’s why you often hear health professionals encouraging you to eat a variety of food or follow a well-balanced diet as no one food group gives you all the vitamins you’ll need. But by eating a variety of different foods, you’ll be in a better position to get a more complete spectrum of all the vitamins you need. See the table below for good food sources.
VITAMIN ABSORPTION
Nutrients from food, vitamins included, are absorbed in your body by your small intestines. It does not absorb 100 per cent of the vitamins present from food. Usually, it will only absorb what the body needs.
So when the body is undergoing a growth spurt or is under stress or recovering from illness, for example, the small intestines will absorb more vitamins as needed.
Gastrointestinal disorders can affect the absorption of vitamins. Depending on the severity, this lack of absorption can cause vitamin deficiencies. In instances such as these, vitamin supplements can be of great use.
The large doses in the vitamin supplement will help the body absorb a small amount that it requires. Therefore, for general health where you don’t have a deficiency, there’s no real need to buy mega doses of vitamin supplements. And remember, mega doses of fat-soluble vitamins can be toxic as the body can’t get rid of the excess.
In special cases where a person cannot absorb vitamins and nutrients due to gastrointestinal issues, doctors will administer injections of vitamins intravenously.
PRESERVING VITAMIN CONTENT
A significant amount of vitamins is lost from fruit and vegetables that are not handled properly or have been stored for an extended period of time.
Not all vitamins are the same, though. Vitamin D can withstand prolonged storage and food preparation. Other vitamins such as vitamin C, thiamine and folate are not as resilient. They are easily destroyed by improper storage and cooking.
Water soluble vitamins can dissolve in cooking water. When you steam vegetables or blanch them in boiling water, don’t throw the liquid. Instead, use it to cook other dishes as the vitamins are present in the water.
Fast cooking methods are recommended to better preserve vitamins. These include steaming, blanching and stir frying.
The next time you’re choosing something to eat, make sure you consider the vitamins the food gives your body. Being mindful about nutrition will put you on the right path to eating well.
