Adhering to the DASH diet, it helps to control the night blood pressure and reduce the risk of fatty liver

A healthy diet model not only helps prevent the occurrence of diseases, but also the basis of disease treatment. Termid high blood pressure diet (DASH diet) emphasizes eating more vegetables and fruits, low -fat milk, whole grains, reducing the intake of red meat, oil, refined sugar and sugar -containing beans, and eat nuts and beans properly. In the 2022 best diet list selected by the American News and World Report, the DASH diet stood out, not only ranked second in the best diet and the best healthy diet, but also in the best heart diet and the best diabetes diet The top 5 in the middle name. Studies have pointed out that adherence to DASH diet can reduce the incidence of metabolic obesity and the probability of Chinese adults suffering from hyperuricemia.

Recently, Gao Xiang, a professor at the School of Public Health University of Fudan University, and Namiko Nakiko, a professor at the School of Health and Human Development of Pennsylvania State University, Wang Li, a researcher at the Basic College of Beijing Union Medical College, Wu Shouling, Professor of Kaizhen General Hospital, and his team. The Journal of Nutrition and "Liver International" have published important research results, adding evidence to the benefits of the Chinese population. Based on the large -scale forward -looking queue research (opening research) data carried out among the Chinese population, the researchers discussed the effects of DASH diet on 24 -hour dynamic blood pressure and non -alcoholic fatty liver disease (commonly known as fatty liver). The results show that insisting on the DASH diet model is not only related to the decrease in the blood pressure fluctuation at night, but also related to the reduction of the risk of fatty liver.

In the study of "Adhering to the DASH Diet to Control the Elderly Emperor's Blood pressure fluctuations of the elderly in China", the elderly who were included in 324, age ≥60 years, and did not take antihypertensive drugs. These participants need to wear instruments to monitor for 24 hours Dynamic blood pressure, fill in the food frequency questionnaire (including 40 kinds of food categories) to review the diet of the past year.

The researchers calculate the DASH diet score of the participants based on the average daily intake and nutritional density of various foods; through the 24 -hour dynamic blood pressure, the participants have calculated during the day (06: 00-21: 59) and the night at night (22: 00-05: 59) The variable range of systolic blood pressure (SBP) and diastolic blood pressure (DBP). On this basis, build a multi -variable linear model to evaluate the connection between the DASH diet mode and the blood pressure results. After adjusting the participants' lifestyle, weight index, hypertension (SBP ≥ 140mmHg or DBP ≥ 90mmHg), and sleep parameters, the researchers found that the DASH score increased by 0.18 units per unit and night SBP volatility increased by 0.18 units at night. At night DBP fluctuations decreased by 0.22 units.

The paper concludes that the following DASH diet model is related to the reduction of the split blood pressure fluctuation among the elderly. This relationship has nothing to do with other factors such as sleep parameters.

"Adhering to the risk of DASH diet can reduce the risk of Chinese fatty liver", a total of about 12,000 Chinese people with an average age of 51.1 years. There are 21.3%(2529) participants in the history of drinking.

Based on a detailed diet assessment and the results of the empty blood samples of the subject at the beginning of the study, the researchers evaluated the correlation between DASH diet scores and fatty liver through multiple logical regression models. After correcting a variety of potential mixed factors such as age, gender, total energy intake, obesity, physical activity, education, smoking, etc., the researchers found that compared with participants with low dash diet scores, the DASH diet scores have a high diet score. The risk of fatty liver is low.

Specifically, compared with participants with low dash diet, people with the highest scores (1/5) have a decrease in the probability of suffering from fatty liver by 18%. Laying analysis shows that among multiple segmented groups with high DASH diet scores, this association has been observed: women's risk of fatty liver is reduced by 33%; overweight/obese patients have a decrease in fatty liver risk by 21%; C. C People with reaction protein (CRP) ≥2.0mg/L, the risk decreases by 44%.

In the DASH diet, different food composition categories have different degrees of influence on fatty liver risk. The intake of vegetables, fruits, beans, whole valleys, and dairy products is more related to the reduction of fatty liver risk; and high -risk of meat, sugar -containing beverages, and high salt intake are related to increased risk.

The paper pointed out that adhering to the DASH diet is related to the reduction of fatty liver risk of Chinese people. It is highly recommended to use a DASH diet, especially women, overweight/obesity, and higher CRP levels. In addition, the relationship between diet and fatty liver is complicated, which is not only related to the calories of food, but also the quality of food.

Gao Xiang said, "In the past, research was concentrated on daytime blood pressure, and at night's blood pressure was ignored for a long time. Although the night blood pressure at night was closely related to the day's blood pressure, it was an indicator with unique clinical significance. Therefore, we studied Dash The potential impact of diet on the blood pressure at night, and found that it may affect its fluctuation level. And fatty liver is a common metabolic disease, which is strongly related to blood pressure, blood sugar, blood lipids and obesity. There is also a lack of evidence of large epidemiological diseases. What needs to be emphasized is that because the DASH diet is mainly based on the Western diet structure, whether it is applicable to the Chinese population, it also needs to be verified by large people. "In addition, Gao Xiang said There is still a certain gap between the recommendation of the habit and the DASH diet. On the one hand, it is necessary to increase the intake of whole grain foods, that is, coarse grains. At present, many people use refined carbohydrates such as refined rice and white noodles as the staple food. It is recommended to match thickness. On the other hand, it is necessary to increase the intake of fruits and vegetables, especially the darker fruits and vegetables, which is conducive to ingesting more plant compounds.
