3. Garlic
Garlic could very well be considered THE spice of life. It is very tasty yet has no carbohydrates, so it doesn’t feature on the glycemic index at all. You can use as much garlic as you’d like to flavor your meals without worrying about a bump in blood sugar.
In fact, garlic has been found to lower fasting blood glucose. Studies have shown that onions have a similar effect on blood sugar, probably because both garlic and onions contain a compound called allicin that gives them their distinctive taste and smell.
