People also tend to believe what they hear repeatedly, even if it has no scientific basis. This is particularly true of stories related to obesity, cancer, vitamins, minerals and food safety. The blood group theory for weight loss seems to be one such example.

The important thing to remember is that when one study becomes a headline or a 30-second sound byte, it may be oversimplified, distorted or overstated. Try and get to the original scientific article whenever possible and you may discuss it with your counselor to evaluate its relevance for yourself. One study does not provide all the answers to our questions, and if it sounds too good to be true, it probably is.

Nutrition is a young science and research evidence must be adopted with common sense in the backdrop of traditional wisdom. Keep an open mind, but also think critically. Nutritional science says there is no best diet, no ‘good’ and ‘bad’ foods. Variety, moderation and balance are the keys to healthy eating. Remember that food is more than the nutrients it provides. It is a part of the way we enjoy and celebrate life.
