Patients only feel coldness in the skin temperature of the affected limb, or mild numbness, and are easily fatigued after activity. The atherosclerotic plaque forms on the inner wall of the arterial vessels, and as the plaque increases and the lumen narrows, the patency of the pipeline is affected, and the blood flow to the lower limbs is reduced, and when the narrowing reaches a certain level or even completely blocked, the blood flow supplying the lower limbs cannot meet the needs, and the symptoms of lower limb ischemia appear. The diet of patients prone to tinea pedis infections that are not easily controlled at the extremities needs to be, first of all, a low-salt, low-fat diet. The sodium in salt increases plasma osmolality, prompting an increase in blood pressure, and high blood pressure can have a detrimental effect on both atherosclerosis and coronary heart disease. It is appropriate to eat vegetable oils, such as soybean oil, vegetable oil, peanut oil, sesame oil, etc. You should eat more foods rich in vitamin C, because vitamin C can promote the hydroxylation of cholesterol, thus reducing the accumulation of cholesterol in the blood and tissues. It is advisable to eat more foods with high fiber, because food fiber is not easily digested by the human gastrointestinal tract, and the intake of high fiber foods can improve the stool habit and increase the amount of bowel movements, so that the cholesterol in the stool can be discharged in time, thus playing a role in reducing the serum cholesterol level. It is better to eat more vegetable protein (such as soy products) and complex carbohydrates (such as starch, etc.), and less simple carbohydrates (such as sugar, sucrose, honey and lactose, etc.). Eat more aquatic sea food, such as kelp, jellyfish, tamari, nori, lamb’s quarters, seaweed and so on, these seafood are good sources of protein and unsaturated fatty acids, as well as various inorganic salts, which have the effect of hindering the absorption of cholesterol in the intestinal tract in the human body. Chinese medicine believes that such foods have the effect of softening and dispersing, so they are often consumed to soften blood vessels. Regular consumption of red pepper, milk and fish is also beneficial for atherosclerosis occlusive disease. In particular, people with high cholesterol are advised to eat red pepper, milk and fish regularly.
