A Danish study showed that the risk of myocardial infarction was reduced by 22 % for a replacement of saturated fatty acids by low GI carbohydrates (most fresh fruit and green vegetables, legumes, cereals...) but increased by 33 % for a replacement by high GI carbohydrates (white bread, white rice, chips, crisps or baked potato, confectionery, chocolate bars, watermelon).
