BMJ: How useful are dairy products? Two servings a day can significantly reduce the risk of diabetes and high blood pressure

Introduction: With the improvement of living conditions, more and more people suffer from lifestyle diseases, of which metabolic syndrome is one of themMetabolic syndrome (MetS) refers to the metabolic disorders that occur in the body's protein, fat, carbohydrate, etc., of which the five most common metabolic abnormalities include elevated blood pressure, abdominal obesity, elevated triglycerides, low-density lipoprotein (HDL) cholesterol and elevated blood sugarResearchers have been studying and analyzing the correlations between dietary and metabolic syndrome risks, seeking to reduce the risk of metabolic syndromeNow, the more dairy products you consume, the lower the risk of diabetes, high blood pressure and cardiovascular disease, according to an international prospective studya large international study of the relationship between dairy intake and the prevalence of metabolic syndrome, and found that eating at least two servings of dairy products a day has a good metabolic effect on the body and reduces the risk of diabetes, high blood pressure and cardiovascular diseaseThe results showed that full-fat dairy products and fermented dairy products were among the most highly reduced rates in the studyThe findings were published May 18 in BMJ Open Diabetes Research and CareParticipants in the project ranged in age 35 to 70 and came from 21 countries: Argentina, Bangladesh, Brazil, Canada, Chile, China, Colombia, India, Iran, Malaysia, Palestine, Pakistan, Philippines, Poland, South Africa, Saudi Arabia, Sweden, Tanzania, Turkey, United Arab Emirates and Zimbabweassess ed'etre in daily diet over the past 12 months using the Food Frequency QuestionnaireDairy products, including milk, yogurt, yogurt drinks, cheese, and dairy products, are classified as full or low-fat (1-2%)Butter and cream are evaluated separately, as butter and cream are not usually consumed in some countries studiedthe study also collected measurements of an individual's medical history, prescription drug use, education, smoking, weight, height, waist circumference, blood pressure, and fasting blood sugarFive indicators of metabolic syndrome were collected for about 113,000 people: blood pressure of more than 130/85 mmHg; waist circumference of more than 80 cm; low (beneficial) high-density cholesterol (less than 1-1.3 mmol /l); blood fat (triglycerides) greater than 1.7 mmol /dl; and fasting blood sugar of 5.5 mmol/l or higherThe total daily average daily consumption of dairy products of the subjects was 179 grams, of which full fat accounted for twice the low fat amount: 124.5 plus 65 gramsAs long as three of the five factors that met the above metabolic syndrome were classified as metabolic syndrome, the data resulted in about 46,667 people suffering from metabolic syndromeresearchers found that whole and full-fat dairy products, rather than low-fat dairy products, were associated with lower rates of metabolic syndrome, with the highest correlation in those countries where dairy intake was usually low At least 2 servings of dairy products per day reduce the risk of metabolic syndrome by 24% compared to non-intake of dairy products per day, and full-fat dairy products alone reduce the risk by 28% researchers tracked the health of nearly 190,000 participants for an average of nine years, during which time 13,640 people developed high blood pressure and 5,351 had diabetes But eating at least two servings of dairy products a day reduces the risk of both cases by 11-12%, while three servings per day reduces the risk by 13-14% It can be seen that the performance of reduced metabolic syndrome in full-fat dairy products is stronger than that of low-fat dairy products but this is an observational study, so the cause cannot be determined The food frequency questionnaire is also subject to recall, and changes in metabolic syndrome are not measured over time, all of which may affect the results of the survey however, the researchers suggest: "If our findings are confirmed in large and long-term trials, then increasing dairy consumption may be a viable and low-cost way to reduce metabolic syndrome: high blood pressure, diabetes and even cardiovascular disease worldwide."
