Carbohydrates are one of the three main macronutrients, along with protein and fat. They are an essential source of energy for the body and are found in a wide variety of foods, including grains, fruits, vegetables, and dairy products. The recommended daily intake of carbohydrates varies depending on an individual's activity level, weight, and health goals, but it typically ranges from 45% to 65% of total daily calorie intake.
For individuals on a low-carb diet, such as the keto diet, the number of net carbs in a food item is an important consideration. Net carbs provide a more accurate representation of the carbohydrates that will impact blood sugar levels and insulin response. By subtracting fibre and sugar alcohols, which have minimal effects on blood sugar, individuals can better manage their carbohydrate intake to align with their specific dietary goals. In the context of a keto diet, which typically restricts net carb intake to 20-50 grams per day, the 38.5 grams of net carbs in the Tesco Cheese and Onion Sandwich may be considered a significant portion of the daily allowance.
