Recently, the Zhejiang Provincial Center for Disease Control and Prevention issued a report on the “Intake of Natrium and Potassium in the Diet of Zhejiang Provinceâ€. It was pointed out that there were too many sodium intakes in Zhejiang and too little potassium intake. Any of Jiguo, the director of the Department of Nutrition and Security at the Food College of China Agricultural University, points out that this situation also exists in Beijing. To change the status of more sodium and potassium, it is necessary to strengthen the intake of vegetables and fruits.
He Jiguo pointed out that the imbalance in sodium and potassium intake has become a nutritional problem. The Chinese Nutrition Society recommends a daily sodium requirement of 2,200 milligrams per person. However, modern people's sodium intake has exceeded the standard. In addition to the well known salt rich in sodium (thus salt-reducing can reduce sodium intake), animal foods also contain higher sodium than plant foods.
A diet low in sodium and potassium may significantly increase the risk of hypertension. And people over 50 years of age and people with familial hypertension are more sensitive to changes in salt intake. If dietary salt increases or decreases, blood pressure will rise or fall. The effect of potassium on blood pressure is opposite to that of sodium. Potassium can dilate blood vessels and reduce vascular resistance, so it can lower blood pressure. It can also increase the sodium content in urine to adjust the sodium-potassium ratio, and it can also lower blood pressure.
So what foods are rich in potassium? According to experts, foods containing more potassium in people's foods are vegetables, fruits and beans. He pointed out that in daily life, people must eat more fruits and vegetables and eat less high-salt foods.
