As we spoke, spring was nearing its end and summer was about to enter. In addition to the daily rise in temperature, various seasonal fruits are also on the market one after another. The hottest months of the year are coming soon, are you ready to welcome them? However, it should be noted that although fruits are sweet, for hypertensive patients with poor blood pressure control, some fruits can only be observed. If you don't shut up and eat too much, it may lead to a surge in blood pressure!
Yes, for patients with hypertension, a light diet with low sodium and limited salt is the basic principle. Many people think that eating some fruits should be okay. Are there any salts in fruits? Moreover, fruits are rich in various vitamins and minerals, which are also beneficial for improving the body's immunity. Fruits rich in dietary fiber can also promote gastrointestinal peristalsis, help digestion, and prevent constipation! If you really think so, congratulations first, you still have some health knowledge. However, when it comes to fruits, we cannot know either one or two, because there are also "alternative" fruits that are not welcomed by blood pressure.
That's too sweet fruit, high sugar fruit. For patients with hypertension, we will not elaborate on salt restriction here, but focus on sugar. The World Health Organization also has regulations on the daily intake of sugar for ordinary people, which is 25 grams. Note that it is considered added sugar (sucrose) and does not include the sugar content in a normal diet. We know that sugar can stimulate the secretion of insulin. Therefore, for people with pancreatic islet dysfunction, insulin cannot be secreted well to process sugar in the blood, which will lead to the rise of blood sugar and induce diabetes.
What is the relationship between insulin and blood pressure? Research has found that insulin not only helps glucose enter cells, but also has a certain anti sodium excretion effect, mainly by increasing the reabsorption of sodium by renal tubules and increasing the responsiveness of aldosterone (a hormone) to angiotensin, thereby increasing blood pressure. Therefore, many patients with diabetes are easy to have hypertension if their blood sugar is not well controlled.
Regarding this discovery, the American Journal of Cardiology has also published a research report questioning whether the trigger for hypertension may not be salt but sugar. They found that if you drink sugary drinks more than three times a day, the risk of developing hypertension directly increases by 87%! We can also try to understand this research viewpoint as follows: a high sugar diet promotes the occurrence of obesity, which is already one of the important causes of hypertension.
Therefore, whether it is the anti sodium excretion of insulin or excessive sugar promoting obesity and increasing the risk of hypertension. Doctors suggest that for patients with hypertension, if blood pressure control is not ideal enough, it is better to eat less sweet foods, especially fruits.
What are high sugar fruits? Is watermelon the tallest?
Summer is the world of watermelons. Many people think that sweet and juicy watermelons must be high in sugar, but in fact, kiwifruit and grapefruit are far superior to watermelons! Like dragon fruit, it doesn't taste sweet, but it is indeed a high sugar fruit with a sugar content of about 15%, while watermelon is only 4.2% and kiwifruit is only about 10%!
Is dragon fruit the highest sugar content? Of course not, hawthorn tastes sour, but its sugar content can reach 22%, and sour dates can even reach 78%! For people who are losing weight, it is also necessary to remember this.
Therefore, it is not enough to judge the sugar content of fruits solely based on their taste and sweetness. Of course, we are not against everyone eating fruits, we just want to say that although fruits are good, do not be greedy. Just like eating, eating small and multiple meals with diverse diets can ensure comprehensive intake of dietary nutrients and avoid skyrocketing blood pressure, right?
