It is generally believed that celery has the effect of protecting blood vessels; scallions mixed with tofu can reduce the accumulation of cholesterol on the blood vessel wall, and have the effect of synergistically lowering blood pressure; onion can lower blood fat, prevent thrombosis, and achieve 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 aids in blood pressure reduction; flavonoids in grapes also lower blood pressure. In addition to the above foods, the latest foreign research has found some little-known “hypotension food.”
1, egg white.
According to the British “Daily Mail” reported on April 9, a new study by Dr. Yu Zhipeng and his research team at Jilin University in China found that eating egg white can lower blood pressure. Dr. Li Lili from the Department of Food and Nutrition of the Academy of Military Medical Sciences told the Life Times reporter that as early as 2009, a study by the University of Alberta in Canada found that certain proteins in eggs can mimic the effects of antihypertensive drugs, only This new study gives a more accurate explanation. Li Lili suggested that patients with hypertension can eat boiled eggs properly, but not more than two per day. Frying eggs heated by high temperature will cause protein denaturation, and the intake of oil exceeds the standard, so it is not suitable for patients with hypertension. Need to be reminded that hypertensive patients must not blindly add egg white, because eating too much eggs will raise cholesterol, but it is harmful to the body; not to stop the drug without authorization, so as not to affect the condition.
2, orange juice
Orange juice is rich in vitamin C, which has the effect of improving human immunity. A new study from the University of Auvergne in France in 2010 found that drinking two glasses of orange juice a day can also lower blood pressure. Scientists have found that middle-aged men drink half a liter 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 various health effects. In addition to the hesperidin found in the study, oranges are rich in vitamin C and other antioxidants, which help to slow down the damage of free radicals to blood vessels; the rich potassium helps lower blood pressure. However, scientists caution that patients taking antihypertensive drugs must seek medical advice before drinking orange juice, grapefruit juice and apple juice to prevent juice from lowering the efficacy of certain drugs. Li Lili 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
A 2012 study by the University of Western Australia in Nutrition Consulting 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. It was found that drinking 3 cups of black tea per day, after 6 months, the systolic and diastolic blood pressure of the participants 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. Li Lili believes that drinking black tea in the morning is better, which can promote blood circulation in the body. It should be noted that in the morning, after drinking tea, it is necessary to have caffeine in the tea. Drinking on an empty stomach will cause excessive caffeine absorption in the stomach, which may cause symptoms such as palpitation and frequent urination. In addition, people with neurasthenia are susceptible to alkaloids and should not drink more black tea.
4, purple potato
A study done by scientists at Scranton University in Pennsylvania found that eating purple potatoes twice a day can lower blood pressure, which is as good as eating oatmeal and does not cause the body to gain weight. It is suitable for hypertensive patients who are overweight. Professor Joe Vinson, the head of the new research, pointed out that purple sweet potato can be cooked with skin. French fries or chips are unhealthy because many nutrients are destroyed during high-temperature frying. Lily reminds that purple potatoes are good but lack protein and fat, so they should be eaten with vegetables, fruits and protein foods. Moreover, the best way to eat purple potatoes is to cook them with skin and try not to use microwave ovens, because the high temperature of the microwave oven will destroy the effective substances. In addition, purple potato skin with black spots is inedible and can cause poisoning.
In 2011, the American Journal of Agriculture and Food Chemistry said that the Food Research Center of the Irish Ministry of Agriculture, through data analysis of 100 related studies, found that eating seaweed often helps to reduce high blood pressure and prevent heart disease. Because seaweed contains bioactive peptides, which are key ingredients that help 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 amount of bioactive peptides. Li Lili suggested that patients with hypertension can use kelp to stew tofu, which has an auxiliary effect on blood pressure reduction. She also reminded that due to the high salt content of seaweed, it is not advisable to eat more, preferably no more than twice a week.
Dr. Chen Zhenyu, a professor at the Chinese University of Hong Kong School of Life Sciences, found in a 2012 study that capsaicin in peppers helps lower blood pressure and blood lipids, thereby reducing the risk of heart disease in the world’s number one killer. Ding Rongjing, a professor of cardiology at Peking University People’s Hospital, said that as early as 2010, China’s Third Military Medical University found that capsaicin in peppers can cause significant relaxation of blood vessels and achieve antihypertensive effect. However, how many peppers you eat each day can be “away from the heart doctor”, which is still a problem that needs further study. Lily reminds 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 ulcer are not suitable for eating more pepper.
In 2011, a new study from the University Hospital of Oslo, Norway, claimed that eating three kiwis a day can lower high blood pressure, which is more effective than eating apples. In the new study, scientists studied 50 male participants and 68 female participants with an average age of 55 years. It was found that eating 3 kiwis per day is better than taking an apple every day. Experts such as Dr. Susanna Steinbam, a New York-based preventive cardiologist, agree that kiwi should be included in the “five servings of fruits and vegetables” diet that is good for heart health. The new research director Dr. Mitt Svendsen believes that the antihypertensive effect of kiwifruit is mainly due to its rich antioxidant lutein. However, two Chinese experts cautioned that this study does not indicate that kiwifruit is a magical fruit, and patients cannot blindly supplement lutein because of this new study.
8, alcohol-free red wine
The US “Fox News” published a new study from the University of Barcelona in Spain for the first time. Men with high risk of heart disease drink 2 cups of alcohol-free red wine per day. After 4 weeks, systolic and diastolic blood pressures are reduced by 6 mm Hg and 2 mm, respectively. Mercury, which is equivalent to a 14% and 20% reduction in heart disease and stroke risk, respectively. Scientists have pointed out that alcohol in ordinary red wines can hinder the antihypertensive effect. Therefore, only alcohol-free wines with an alcohol content of less than 0.5% can exert 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 heart and blood pressure, but a study by the University of Rotterdam School of Medicine in the Netherlands in 2011 showed that red wine does not lower blood pressure. Li Lili believes that this Spanish study is likely to explain the results of the Dutch study, that is, a certain concentration of alcohol affects the antihypertensive effect of red wine.
9, beetroot juice
The British “Daily Mail” reported on April 15 that the American Heart Association magazine “Hypertension” published a new study in the UK found that drinking beetroot juice often helps to reduce high blood pressure. The new study found that drinking 8 ounces (about 227 grams) of beetroot juice a day in hypertensive patients can lower blood pressure by about 7%. After drinking the beetroot juice for 3-4 hours, the antihypertensive effect is optimal and the effect lasts for 24 hours. Ding Rongjing pointed out that beetroot juice is rich in vitamin C, vitamin K, dietary fiber and polyphenols, which are good for heart health, and has a role in lowering fat and lowering potassium. According to Li Lili, beetroot is more common in southern China and is traditionally used to make sucrose. This study gives a completely new way of eating. Beetroot also contains a large amount of anthocyanins, which have anti-oxidation effect and remove oxidative free radicals in the blood, which is beneficial to cardiovascular health. But Li Lili pointed out that the sugar in the beetroot is very high, and drinking too much will raise blood sugar, so it is appropriate.
