Replacing processed carbohydrates (high GI/GL grains, potatoes, added sugars) with unprocessed carbohydrates (whole grains, legumes, whole fruits) or healthy fats reduces the risk of obesity, type 2 diabetes, and cardiovascular disease.

Focus on the quality of your carbohydrates rather than just cutting them out. Swap refined grains, potatoes, and sugary drinks for whole grains, legumes, and whole fruits. This shift is strongly linked to better metabolic health and lower disease risk.
