Hong Kong experts answer common questions about healthy eating

In recent years, many people have become highly conscious of their health and diet. We have an idea of what's good for us and what's not, and we've progressed way beyond "an apple a day keeps the doctor away".

There are now thousands of nutritional guides and diet books available. Some say we should eat like a caveman; others swear by supplements. It can be confusing. Here are some of the most common questions we're asked.

Some believe that a gluten-free diet will help ward off disease, but, in reality, unless you have celiac disease or are gluten sensitive, gluten-free food is not necessarily healthier. For example, soda is gluten-free but certainly not healthy.

Processed gluten-free foods can be high in calories, fat, artificial colourings and chemicals. So instead of focusing on "gluten-free", focus on incorporating whole foods, hearty grains, and fruits and vegetables into your diet.
