Less known buck food recommendations

Blood pressure depends on drugs, but it cannot be denied that some foods have also been proven to have the effect of assisting blood pressure reduction. Starting from eating, learning to protect blood vessels may be a required course for you.

It is generally believed that celery has the effect of protecting blood vessels; small onions mixed with tofu can reduce the accumulation of cholesterol on the blood vessel wall and have a synergistic effect in lowering blood pressure; onions can lower blood fat, prevent thrombosis, and achieve an auxiliary antihypertensive effect; vinegar can reduce blood circulation The obstruction improves the symptoms of hypertensive patients; an active ingredient rich in watermelon regulates vascular tone and assists blood pressure depressurization; flavonoids in grapes also lower blood pressure. In addition to the above foods, the latest overseas research has found some lesser-known "hypertensive foods."

1. Eggs.

According to a report in the British "Daily Mail" on April 9, a new study completed by Dr. Yu Zhipeng and his research team at Jilin University in China found that eating egg white can lower blood pressure. Dr. Lili Li from the Department of Food and Nutrition of the Academy of Military Medical Sciences told Life Times that as early as 2009, a study at the University of Alberta in Canada found that certain proteins in eggs can mimic the effects of antihypertensive drugs. This new study gives a more accurate explanation. Li Li suggested that patients with hypertension can eat boiled eggs properly, but not more than two per day. High temperature heating of fried eggs can cause protein denaturation and excessive oil intake, so it is not suitable for high blood pressure patients. It should be reminded that hypertensive patients must not blindly add egg whites, because eating too much of an egg can increase cholesterol, but it is harmful to the body; not to arbitrarily stop the drug, so as not to affect the condition.

2. Orange juice.

Orange juice is rich in vitamin C and has the effect of improving human immunity. A new study by the University of Avignon in France in 2010 found that drinking two glasses of orange juice each day can also lower blood pressure. Scientists have found that middle-aged men drink half a litre of orange juice (about 2 cups) a day for a month and their blood pressure levels drop significantly. The active ingredient in orange juice is mainly hesperidin, which is also rich in tea, fruit, soybeans and cocoa, and has a variety of health effects. In addition to the hesperidin found in the study, antioxidants such as vitamin C, which are rich in oranges, help to slow the damage of free radicals to blood vessels. The abundant potassium helps reduce blood pressure. However, scientists cautioned that patients taking antihypertensive drugs must consult doctors before drinking orange juice, grapefruit juice and apple juice to prevent juice from reducing the efficacy of certain drugs. Liliao reminded that orange juice must be freshly squeezed, because the finished product sold in the supermarket has a high sugar content, which is not conducive to stable blood sugar.

3. Black tea.

In the British “Nutrition Counseling” magazine published in 2012, a study by the University of Western Australia found that drinking 3 cups of black tea a day can significantly reduce high blood pressure. Professor Jonathan Hodgson and colleagues conducted a comparative study of the antihypertensive effects of black tea, coffee, and placebo. The results showed that drinking 3 cups of black tea a day, after 6 months, the participants' systolic and diastolic blood pressure decreased by 2 mm Hg and 3 mm Hg, respectively, which is equivalent to a 10% reduction in the risk of hypertension and heart disease. Lili Li believes that drinking black tea in the morning is better, it can promote blood circulation in the body. It should be noted that drinking tea in the morning must be done after breakfast. Because tea contains caffeine, drinking too much can cause caffeine to be absorbed too much in the stomach and stomach, causing symptoms such as palpitation and frequent urination. In addition, people with neurasthenia are susceptible to alkaloids and should not drink black tea.

4. Purple sweet potato.

A study done by scientists at the University of Pennsylvania, Stanton, USA, found that eating sweet potatoes twice a day can lower blood pressure, which is as good as eating oats, and it does not cause body weight gain. It is suitable for hypertensive patients who are overweight. The new research head Professor Joe Vinson pointed out that purple sweet potatoes can be eaten with skin. French fries or potato chips are unhealthy because many nutrients are destroyed during high-temperature frying. Lilia reminded that although purple sweet potato is good but lacks protein and fat, it should be eaten together with vegetables, fruits and protein foods. Moreover, the best way to eat purple sweet potatoes is to cook and eat with skin. Try not to use microwave ovens to bake, because the high temperature of microwave ovens will destroy the effective substances. In addition, purple potatoes with black spots are inedible and can cause poisoning.

5. Seaweed.

In 2011, the United States "Journal of Agriculture and Food Chemistry" said that the Irish Food Research Center of the Ministry of Agriculture through data analysis of 100 related research found that eating seaweed helps reduce high blood pressure and prevent heart disease. Because seaweed contains key bioactive peptides that help to reduce blood pressure, it acts like a common antihypertensive drug. Seaweed foods mainly include: wakame, kelp and seaweed. In addition, milk also contains a large number of biologically active peptides. Lili Li suggested that hypertensive patients can stew tofu with kelp, which has an auxiliary effect on blood pressure. She also reminded that since seaweed contains more salt, it should not be eaten too much. It is better not to exceed twice a week.

6. Pepper.

Dr. Chen Zhenyu, a professor of life sciences at the Chinese University of Hong Kong, found in a 2012 study that capsaicin in pepper helps lower blood pressure and blood lipids, which in turn reduces the risk of heart disease, the “world’s number one killer.” Ding Rongjing, a professor of cardiology at the Peking University People's Hospital, said that as early as 2010, China’s Third Military Medical University found that capsaicin in capsicum can cause significant relaxation in blood vessels and achieve antihypertensive effects. However, how many chili peppers a day can be “distant from the cardiologist” is still a problem that needs further study. Liliao reminded that capsaicin can promote gastric peristalsis, blood flow, and mucus secretion, and has a stimulating effect on the stomach. Therefore, people suffering from gastritis and gastric ulcers are not suitable to eat chili.

7. Kiwifruit.

In 2011, a new study by the University Hospital of Oslo, Norway, declared that eating three kiwifruits a day can reduce high blood pressure, which is more significant than eating apples. In the new study, scientists studied 50 male participants with an average age of 55 and 68 female participants. As a result, it was found that eating 3 kiwifruits a day is more effective than taking one apple a day. Experts such as Dr. Susanna Steinbach, a New York-based preventive cardiologist, agreed that kiwifruit should be included in the heart-healthy “five servings of fruits and vegetables” diet. According to Dr. M. Svendson, head of the new research, the antihypertensive efficacy of kiwifruit comes mainly from its rich antioxidant lutein. However, two Chinese experts have warned that this study does not mean that kiwifruit is a miraculous fruit and patients should not blindly add lutein for this new study.

8. Alcohol-free red wine

The United States “Fox News” published a new study in 2012 at the University of Barcelona in Spain. It was found for the first time that high-risk men with heart disease drink 2 cups of alcohol-free red wine per day. After 4 weeks, systolic and diastolic blood pressures were reduced by 6 mmHg and 2 mm, respectively. Hg, equivalent to a 14% and 20% reduction in the risk of heart disease and stroke, respectively. Scientists pointed out that the alcohol in ordinary red wine will hinder the antihypertensive effect. Therefore, only alcohol-free wine with an alcohol content of no more than 0.5% can play a certain antihypertensive effect. In fact, many previous studies have shown that drinking one or two glasses of red wine a day is good for the heart and blood pressure, but a 2011 study by the University of Rotterdam School of Medicine in the Netherlands showed that red wine does not lower blood pressure. Lili Li believes that the Spanish study is likely to explain the results of the Dutch study that a certain concentration of alcohol affects the red wine's antihypertensive effect.

9. Beetroot juice.

British "Daily Mail" reported on April 15, the American Heart Association magazine "hypertension" published a new study in the United Kingdom found that drinking beetroot juice helps reduce high blood pressure. The new study found that drinking a cup of 8 ounces (about 227 grams) of beetroot juice a day can reduce blood pressure by approximately 7% in hypertensive patients. After 3-4 hours of drinking beetroot juice, the antihypertensive effect is best, and the effect is sustainable for 24 hours. Ding JINGJING pointed out that beetroot juice is rich in vitamin C, vitamin K, dietary fiber and polyphenols that are beneficial to heart health, and it has an effect on lipid lowering and potassium lowering. According to Lili Li, beetroot is common in southern China and is traditionally used to make sucrose. This study gives a new way of eating. Beetroot also contains a large number of anthocyanins, which have anti-oxidant effects and remove oxidized free radicals in the blood, which is beneficial to cardiovascular health. But Liliao pointed out that sugar beetroot is very high, and drinking too much can raise blood sugar, so it is appropriate.
