For carbohydrates, a good rule of thumb is to opt for the least processed state of the carbohydrate possible. This means taking whole kernel bread over white bread, brown rice over white rice, whole barley over pre-processed barley, and more. Traditionally processed food like steel-cut oats, natural granola and muesli, and stone-ground bread could make for good low glycemic index food alternatives.
In the same way, staying away from food with high GI ratings like white potatoes and refined grain products like bread, cereal, and pasta would help your diet.
A low glycemic index diet would mean limiting concentrated sweets and sugary treats. This includes high-calorie foods, regardless of their GI content, like ice cream and other sweetened snacks.
Though fruit juice is often good for you in vitamins and fiber content, it is recommended that you keep it to at most a half cup a day. You are also recommended to go for fresh, unsweetened fruit juice. Drinks that are sweetened by sugar should generally be avoided. This includes soft drinks, artificially flavored shakes, and sweetened tea.
