Because dairy products have relatively high energy and also contain a certain amount of carbohydrate , many diabetics dare not eat dairy products. So can it be eaten? The answer is yes, it is good for health. Recently, researchers found in a large study that eating at least two servings of dairy products per day can reduce the risk of developing diabetes , hypertension and metabolic syndrome (metabolic syndrome is a collective name for multiple homologous diseases and increases the risk of cardiovascular disease). The study, titled “The Relationship of Dairy Consumption and Metabolic Syndrome, Hypertension and Diabetes in 147,812 People from 21 Countries,” was published in the latest issue of the journal BMJ Open Diabetes Research & Care.

Purpose of the study
There are several studies examining the risks of metabolic syndrome, hypertension and diabetes among people who consume dairy products. These studies have been reported mainly from North America and Europe, while there is little evidence in India, China, Africa and South America.
Metabolic syndrome includes characteristics of hypertension, abdominal obesity, elevated triglycerides, high-density lipoprotein (HDL) cholesterol and abnormal blood sugar, which increases the risk of heart disease, diabetes, related diseases and death. Studies have shown that dairy products, including whole-fat foods and fermented dairy products, including yogurt and cheese, have beneficial effects on metabolism and can reduce the risk of metabolic syndrome and hypertension.

This study is part of a prospective urban rural epidemiological (PURE) study, aiming to observe the effects of dairy intake and the prevalence of metabolic syndrome, diabetes and hypertension after an average 9.1 year follow-up.
Study Content
This is part of a prospective urban rural epidemiology (PURE) study, which includes people aged 35 to 70 who live in 21 different countries on five continents. These countries are: " Argentina , Bangladesh , Brazil , Canada, Chile , China, Colombia, India, Iran , Malaysia , occupied Palestinian territory, Pakistan , Philippines , Poland , South Africa, Saudi Arabia , Sweden , Tanzania , turkey, United Arab Emirates and Zimbabwe ." Participants were followed up on average for 9.1 years and tested in 112,922 participants. At follow-up, a total of 57,547 people who did not have hypertension at the beginning of the study were diagnosed with hypertension, and 131,481 people underwent blood sugar test with followed. The study observed that dairy intake and its components were correlated with the prevalence of metabolic syndrome.
provided participants with a questionnaire for food (Food Frequency Questionnaire-FFQ), and dairy products consumed in one day include "milk, yogurt, yogurt drinks, cheese and mixed dishes prepared with dairy products." Foods are also classified according to ingredients, including " whole milk , whole fat yogurt, whole fat cheese, whole fat yogurt drinks and mixed dishes prepared with whole fat dairy products" as well as low-fat dairy products such as people with milk content of 1-2% "skimmed milk, low fat yogurt , low fat cheese and low fat yogurt drinks".

other parameters, such as age, gender, smoking status, education level, weight, height, waist and hip circumference, waist and hip ratio and blood pressure. Blood glucose, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDLC), triglycerides, apolipoprotein A1 and apolipoprotein B were analyzed in blood samples.
Baseline cutoff value is:
Blood pressure 130/85mm Hg waist circumference above 80 cm HDL less than 1-1.3 mmol/l triglyceride greater than 1.7 mmol/dl Fasting blood sugar exceeds 5.5 mmol/l

From the questionnaire, the average daily consumption of dairy products is 179 grams, of which 124.5 grams of whole fat and 65 grams of low fat.
study found that the main finding of this study is that high consumption of whole fat (non-low-fat) dairy products reduces the risk of hypertension and diabetes. High-consumption dairy products are defined as at least two servings per day compared to non-intake dairy products. Those who consume more whole-fat dairy and low-fat dairy products also have a lower risk of metabolic syndrome. Those who consume only low-fat dairy products have no alteration in the risk of developing metabolic syndrome. Those who eat at least two servings of dairy daily have a 11% to 12% lower risk of hypertension and diabetes, and those who take three servings have a 13% to 14% lower risk of those who take three servings.

At the beginning of the study, 13,640 and 5,351 participants without hypertension and diabetes, respectively, experienced this during the follow-up process.
Conclusion: Eating more dairy products in moderation is good for health
Researchers concluded that "intake of more whole fat (rather than low fat) dairy products is associated with reducing the prevalence of MetS and most of its constituent factors and reducing the incidence of hypertension and diabetes." They called for a broader randomized controlled trial to observe the effects of whole fat dairy products and the developmental risks of hypertension, diabetes and metabolic syndrome. They said: "If our results are confirmed in long-term trials large enough, increasing dairy consumption may be a feasible and low-cost way to reduce global MetS, hypertension, diabetes and ultimate cardiovascular disease events."

Therefore, diabetics can eat dairy appropriately, and whole-fat dairy products are more healthy. #Health Knowledge Popular Science#
