The difference between whole wheat toast and ordinary toast is that it uses refined flour instead of whole wheat flour to remove bran and wheat germ. Whole wheat toast is characterized by brown color, and many bran particles can be seen with the naked eye. It has a rough texture, but it smells good.
Whole-wheat toast is relatively high in calories, with 230 calories per100g of whole-wheat toast. It is mainly made of some wheat flour. Whole-wheat toast is very popular abroad, especially rich in vitamin B and especially liked by microorganisms, so it is more prone to mildew than ordinary toast. Whole wheat toast is characterized by brown color, and many bran particles can be seen with the naked eye. It has a rough texture, but it smells good.
In order to reduce costs, some bakeries usually make fake whole wheat toast. One is "coloring agent", in which caramel or syrup is added to white flour, and the "carbonization" phenomenon caused by high baking temperature is used to make toast bake naturally light brown and look like "whole wheat toast".
It should be noted that this kind of toast is cut tightly and tastes flawed. Second, adding germ and bran to white flour, the processed toast looks and tastes like whole wheat toast. Although it tastes rough, I feel that the bran is in my mouth and the wheat is not full enough.
Physiological function of heat
Just as computers consume electricity and trucks consume oil, so do human daily activities. Heat not only provides energy for people's exercise, daily work and life, but also provides energy for human life activities, blood circulation, breathing, digestion and absorption. People who lose weight can burn fat through exercise, which can accelerate calorie consumption and achieve the goal of healthy weight loss.
Generally speaking, adults need at least 65,438+0,500-2,000 calories a day to maintain body function, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption varies with individual height, weight, age and gender.
Human survival needs energy, which is obtained from food. The calorie content in food is a measure of how much potential energy food produces. 4000 calories because carbohydrate heat production =4 calories/gram, protein heat production =4 calories/gram, fat heat production =9 calories/gram. Food is generally composed of these three substances. Therefore, as long as we know the contents of these three substances in food, we can know how much heat or energy food contains.
