Carbohydrates
Source: Grains, fruits, vegetables, and beans.
Health: Carbohydrates are an important part of a healthy diet. They are a major source of energy that the body acquires through glycolysis glucose, a basis unit of carbohydrates. Carbohydrates range from complex starches to simple sugars.
Illness: Insufficient carbohydrate consumption leads to general weakness and can affect multiple systems. Excess simple carbohydrates in the diet can lead to glucose intolerance, insulin insensitivity, and eventually diabetes.
Death: If left untreated or mis-managed diabetes can increase the risk of death from complications such as cardiovascular diseases, infection of slow healing wounds, insulin-induced comas, diabetic shock etc.
