People with low blood pressure should be careful not to eat raw and cold foods in their diet. Instead, they should consume more warming, nourishing foods with high nutritional value and avoid foods that affect blood pressure, such as celery. Celery has a blood pressure-lowering effect, and regular consumption can decrease blood pressure. Those with low blood pressure should pay attention to adjusting their dietary structure, replenishing the calories needed by the body, and raising blood pressure. Regular consumption of lean meat, eggs, fish, shrimp, high-quality protein or some soy products, as well as fruits high in vitamins, can help increase blood pressure, improve overall blood supply, and protect vital organs.
