High-carbohydrate foods to avoid include candy, desserts and sugary drinks, according to Mayo Clinic. Avoid foods with refined grains and added sugars whenever possible. Eating low-fat dairy products instead of standard dairy products is a healthier choice.
Avoid processed and refined white foods, such as cereal; pasta; flour and related foods, such as crackers and bread; and sugar, including high-fructose corn syrup, recommends WebMD. Substitute white bread and white rice with whole-grain bread and brown rice. Although potatoes, onions, cauliflower and white beans are white, they are still healthy choices because they are not processed.
Ideal high-carbohydrate foods contain significant amounts of fiber, notes WebMD. These include fruits, vegetables, beans and whole grains. These fiber-rich carbohydrates help to regulate blood sugar levels because the body absorbs them slowly. Not eating enough fiber places you at an increased risk of heart disease. Add beans and legumes, such as peas and lentils, to your diet for fiber, minerals and protein.
Although added sugar may not be harmful when consumed in moderation, it does not offer any health benefits, states Mayo Clinic. Eating too much sugar can cause health problems, such as weight gain, tooth decay and poor nutrition, so avoid it whenever possible.
