A low-salt diet is good for preventing atherosclerosis, cardiovascular disease, and hypertension. Middle-aged and elderly people who eat heavier salt and usually like salty food, and even young people, can develop higher blood pressure. As they get older, if they do not eat a light diet and often prefer a high-salt diet, the risk of high blood pressure appearing will be greater than a normal low-salt diet. Northerners have a heavier taste and put more salt in their cooking, and some families are not able to eat in when there is no salt, so generally this family will suffer from high blood pressure, and even cardiovascular atherosclerosis. If hypertension appears during the hospital examination, and atherosclerosis is found during the cardiac ultrasound and neck vascular ultrasound, it is important to consider whether it is related to the dietary habits at home, and this condition will appear if you often like to eat salty and greasy food. Therefore, it is important to actively control the diet and to have a low-salt diet, which is good for health.
