So between the sugar and the alcohol, an average person he is now getting approximately half of their daily calorie quota from sources that are hardly but nutritious. Even more calories in a typical modern diet come from processed fats –cooking fats, salad oils as well as oils added to baked goods. Such fats –which they contain a minimum amount of vitamins –may produce another 15 to 30 percent of our daily calories.
