In diet, you'd better pay attention to the following points: eat more foods with high calorie, high protein and rich vitamin content, such as milk, sea fish and various fresh fruits. Try to eat less spicy food, and don't eat anything that is phlegm-producing or hot. Such as pepper, ginger, onion, leek, mutton, dog meat, pig head meat, rooster, shrimp and crab, etc. The most important thing for people with AB blood type is to control their daily salt intake. Because the blood of AB blood type is inherently viscous, this situation will be aggravated if the salt intake is excessive. It is best for people with AB blood type to consume less than 6 grams of salt every day. Kidney beans, green beans, corn, buckwheat or sesame will all affect the insulin secretion of people with AB blood type, so it is best to eat less. Because if the production of insulin is restricted, it will lead to too little blood sugar, and the blood sugar will drop after meals, which will not effectively metabolize food and cause fat accumulation. For people with AB blood type, the key to slimming is to choose the right food. If you want a healthy and slim figure, you'd better not choose seeds, buckwheat, wheat and corn.
