Fast-carb foods are foods containing carbohydrates that the body breaks down quickly, converting the food into glucose. Researchers have connected fast-carb foods with a higher risk of heart disease, type 2 diabetes and colorectal cancer. Eating fast-carb foods leads to a spike in blood sugar, an unhealthy trend over time.
Common fast-carb foods include sugary sodas, white bread, chips, steamed rice and potatoes. Rather than contribute nutritionally to the body, these foods simply boost blood sugar and spark an insulin response from the body, setting off a chain that, if taken to extremes and made part of a habit, leads to the development of type 2 diabetes.
Some sweet vegetables and fruits are also fast-carb foods, but they also have enough fiber, if eaten raw, to counteract the harmful effects of the fructose that they contribute to the body. The slow-carb foods, also known as "good carbs," give the body a higher level of fiber and nutrition in addition to the sugar. Fiber is crucial for good digestive health, and it reduces the "bad" LDL cholesterol, cutting the risk of heart disease. Slow-carb foods also create a full feeling more quickly, helping people eat smaller meals and control weight more effectively. Fiber-rich vegetables and beans are slow-carb foods.
