The resistance encountered by the blood as it flows through the blood vessels is known as resistance to blood flow. As the blood flows, it consumes energy due to friction, generally in the form of heat energy. This thermal energy cannot be converted into potential or kinetic energy of the blood, so the pressure of the blood gradually decreases as it flows through the blood vessels. In the case of turbulent flow, the individual mass points in the blood constantly change the direction of flow, so the energy consumed is more than in laminar flow, and the resistance to blood flow is greater. Dietary considerations for increased resistance to blood flow: 1, choose foods that can dilute blood: these foods are inhibit platelet aggregation, prevent thrombosis of hawthorn, black fungus, garlic, onions, green onions, persimmon peppers, mushrooms, strawberries, pineapples, lemons, etc.; anticoagulant foods similar to the effect of aspirin are hawthorn, tomatoes, red grapes, oranges, ginger; with the effect of regulating lipids have hawthorn, spirulina, celery, Carrot, konjac, nori, kelp, amaranth, walnuts, corn, sesame, apples, kiwi and so on. 2.Reasonable diet: eat less animal offal and animal fat, eat less fried food, dinner should not eat more meat and fish thick food, eat less sweets. Usually eat light food, vegetarian-based, coarse and fine food with. 3, eat more food rich in lecithin: eat more soybeans and soy products, eggs, fish. Favorable to improve blood viscosity, is not easy to form blood clots. 4, eat more fruits and vegetables containing vitamin C: vitamin C has the role of regulating blood lipids; vegetables in the intestinal fiber can prevent the absorption of cholesterol can reduce blood viscosity.
