The low GI diet

The low-GI (glycaemic-index) diet isn’t just the one that helps us lose weight—it’s also the healthiest.

After poring over 20 studies, David Ludwig, from the Children’s Hospital in Boston, MA, says that every doctor should advise his patients to adopt the GI diet, especially as a lifestyle choice to prevent diabetes, heart disease and obesity.

The key is that it differentiates between ‘good’ and ‘bad’ carbohy-drates. Instead of banning all sugars and starches, it rules out only those carbs that increase blood-glucose levels too rapidly. This includes most processed foods such as breakfast cereals, white bread and white rice, cakes and biscuits.

Low-GI foods include fruits, vege-tables, pulses and grains, such as brown rice, that have not been overly processed (Lancet, 2007; 369: 890–2).
