Vitamins and minerals are substances in your diet that are essential for good health. Taking vitamins and minerals as supplements, however, are a different matter. Here are the facts behind some of the myths.
Myth (1) – Just as good as food
While they’re manufactured to the exact same chemical structure, supplements don’t work as well for your body as naturally-occurring vitamins and minerals in food.
Food is a source of not just vitamins and minerals, but also other substances such as phytochemicals in plants, which all work together, whereas supplements tend to work in isolation.
Myth (2) – Compensate for a poor diet
Certain people may need supplements for medical reasons, such as folate for pregnant women to prevent abnormalities in the foetus. However a vitamin and mineral supplement should not be seen as a way to compensate if you have a poor diet. A healthy, balanced diet is more nutritious for the reasons explained above.
Myth (3) – Cure and prevent medical conditions
The research shows that you only need a small amount of vitamins and minerals to help maintain good health and large amounts usually don’t act like a medicine to cure or prevent medical conditions.
For example, vitamin C doesn’t reduce the chances of catching the common cold, though it may shorten how long it lasts and the severity of your symptoms. Similarly, vitamin E doesn’t prevent you from developing heart disease.
Myth (4) – Harmless
Taking very high dosages of vitamins such as A, B6, D, E and K can be toxic. Unhealthy interactions can also occur such as large amounts of zinc can reduce the absorption of iron and copper.
