The low sugar diet is primarily aimed at those suffering from diabetes, heart disease, and obesity. However, lowering sugar intake can benefit anyone trying to create more balance in their diet and a healthier lifestyle overall.
The low-sugar approach is seen in many of the diets recommended by dieticians, such as the Mediterranean diet, and the DASH diet. Simply, a low sugar diet has eliminated all foods with added and artificial sugars along with carbohydrates that are quickly broken down into sugar in the body.
Some foods, like fruit (citrus fruits and berries in particular), whole grains, and sweet potatoes are acceptable, in moderation, by dieticians, but some wanting to go to extremes will try to also eliminate those from their diets.
Obviously any fruits high on the glycemic index scale, white bread, even whole wheat with added sugar, most drinks, packaged snack foods, and alcohol would not be in the diet.
