The term 'NO-NOS IN SOME DIETS' can be summarized as foods that are not recommended for certain diets. The crossword solution for this term is CARBS, which stands for carbohydrates. Carbohydrates are a type of macronutrient found in many foods, such as grains, fruits, and vegetables, and are an important source of energy for the body. However, some diets, such as low-carb or ketogenic diets, restrict the intake of carbohydrates to promote weight loss. Therefore, CARBS are considered a 'no-no' in these diets.
