Oats

Oats are high in soluble fiber, which means that it is the perfect breakfast option. This is because soluble fiber has been shown to reduce blood sugar levels. A review of 16 different studies revealed that consuming oats significantly reduced fasting blood sugar levels and HbA1c compared to control meals. Another study found that drinking water mixed with oat bran before consuming white bread reduced blood sugar after meals. This was when compared with just drinking water on its own.
