The heat produced by food is calculated in calories, and the heat used for nutrition is kilocalories, which is the heat needed to raise the temperature of one kilogram of water by one degree Celsius.
1g protein generates 4 kilocalories after absorption and oxidation in vivo, and 1g sugar generates 4. After in vivo absorption and oxidation, 1kcal, 1g lipogenesis 9. It is 3kcal after absorption and oxidation in vivo.
The calories of food can be calculated from the above figures. For example, every two slices of bread contain 1 1. 1g carbohydrate, 0.6g fat and 3. 1g protein, so the heat generated by 1g bread is as follows:
Carbohydrate16×11.2× 716.8 kcal
Fat 16×0。 6×9=86.4 calories.
Protein16× 3.1× 4 =198.4 kcal.
Total 100 1. Six calories.
Many office workers take bread out of the refrigerator in the morning and send it to their mouths without baking it. Huaxin nutritionist said that bread slices, steamed bread slices and other staple foods are carbohydrates, which will stimulate gastric acid secretion and aggravate pantothenic acid; However, if you eat toast and steamed bread slices before, you can play the role of "nourishing the stomach".
This is because a gelatinized layer will be formed on the burnt bread slices and steamed bread slices, which can neutralize gastric acid, inhibit gastric acid secretion and protect gastric mucosa. "This is an ancient diet therapy method, which is mainly suitable for patients with chronic superficial gastritis and most people with poor gastrointestinal tract."
In addition, Huaxin reminds everyone that we should first pay attention to the baking temperature, and bake it until it is orange or golden yellow. Don't burn it, or it won't pay off. Secondly, people with poor gastrointestinal tract should not eat too much toast and baked steamed bread slices, only 1-2 slices each time;
Thirdly, toast and baked steamed bread slices don't have to be eaten hot, but can be dried a little; Finally, this diet therapy is only suitable for minor stomach diseases, such as chronic superficial gastritis. If you reach the point of atrophic gastritis, you have to go to the hospital, not by this method.
