Patients with hypertension can eat raisins. The main nutrients of raisins are glucose and amino acids, which have no effect on blood pressure. Raisins do not affect blood pressure and do not cause high or low blood pressure. They also do not conflict with the antihypertensive medications that are commonly taken, nor do they increase or decrease the effectiveness of conventional antihypertensive medications. Patients with hypertension should try to control the amount of raisins they eat and not eat too much of them, because patients with hypertension often have combined diabetes, and if they have combined diabetes, they should try not to eat raisins. However, if a hypertensive patient has neither diabetes nor other diseases that cause cardiovascular disease, eating raisins has no effect. But try to eat raisins after meals, if you eat raisins on an empty stomach, it is more stimulating to the stomach.
