If you happen to be one of those people that love the taste of seafood, especially tuna or salmon, consider yourself lucky. Fatty fishes such as these are incredibly rich in nutritious omega-3s. If you recall from the previous chapter, fats—like protein and fiber —are an excellent way to slow the spike in insulin levels that carbohydrates induce .

Experts recommend eating fish at least twice a week. Because of the omega-3 content of these meals, they are also a great opportunity to indulge in high-GI foods that you just can’t live without. The fatty acids will help balance your insulin levels despite the surge of blood sugar the “indulgence” foods will trigger.

It’s worth noting here that the low-GI diet recognizes your need to indulge once in a while. Diets that don’t take into account the need to “break the rules” are far more likely to fail you than ones that allow the occasional “forbidden fruit.”
