New study Chinese is one egg a day prone to diabetes? It's not that simple!

Over the past two days, a new study Chinese the risk of eating eggs and diabetes in groups has received a lot of attention.
that "eating one egg a day increases the risk of diabetes by 60 percent."
eggs can eat, how much to eat, and for a while became a public problem.
this study is true, but the conclusions are not so simple.
we understand the health effects of eggs? Let's take a look at the main points and related information of this study.
It's too long not to look at the version: a 60 percent increase in risk is rough data, and when other diabetes risk factors are adjusted, the correlation is significantly reduced and not significant≠
1. The data on how eating eggs increases the risk of diabetes is the result of a recent study published in the British Journal of Nutrition, conducted in collaboration with researchers from the Chinese Medical University, the University of South Australia and the University of Qatar.
Screenshot Source: The British Journal of Nutrition study data is derived from the China Health and Nutrition Survey (CHNS), a well-known large-scale nutrition study in China that continues in nine provinces in China and randomly covers samples from urban and rural areas.
the analysis included data on 8,545 ≥18-year-old adults who participated in CHNS between 1991 and 2009, during which seven dietary surveys were conducted in which participants were asked to record their egg consumption through 3-day, 24-hour dietary memories and food weighing.
subjects were 50.9 years old on average and their diet was followed up for an average of 11 years.
2009, researchers diagnosed diabetes based on their peresacose blood sugar and found that 11 percent of the subjects had diabetes.
basis of this, Chinese the association between eating eggs and diabetes was analyzed.
2. How do you understand the results of the study? According to the paper, 25 percent of those who ate the least eggs (≤9g per day) had a 60 per cent increased risk of diabetes and 25 per cent who ate the most eggs (≥37.6g per day) had a 65 per cent increased risk of diabetes.
data are the source of what at first glance is a startled "eat one more egg a day and increase the risk of diabetes by 60%."
this interpretation is not accurate.
the first thing to note is that this is not adjusted for other underlying diabetes factors under the statistical results.
After adjusting demographic characteristics such as age, gender, urban and rural areas, income level, and educational level, as well as personal habits and underlying health conditions such as smoking, alcohol consumption, physical activity, eating habits, overweight/obesity, hypertension, serum cholesterol and energy intake, this correlation is significantly reduced and is not statistically significant.
other words, these "other" factors have a small impact on diabetes risk, and together they may even exceed the effects of eggs.
average egg consumption and diabetes risk from 1991 to 2009 in the CHNS study. Model
1 adjusted age, gender, urban and rural areas, income level, education level, model 2 on the basis of model 1, continued to adjust smoking, alcohol consumption, physical exercise, eating habits, overweight/obesity, hypertension, model 3 on the basis of model 2, continue to adjust serum cholesterol and energy intake.
sensitivity analysis was conducted among 2,425 subjects who participated in all seven dietary surveys.
(Source: Resources; Translation: Medical New Perspectives) And, when adjusted for these factors, the risk of diabetes increased by 25 per cent for those who ate the most eggs compared to those who ate the least eggs, compared with a higher average risk for those who ate the median level than those who ate the most eggs.
look at another set of relatively convincing data -- a less significant association among the 2,425 subjects who took part in all seven dietary surveys, although people who ate more eggs had a higher risk of diabetes.
two groups of adjusted data, the overall did not fully conform to the "more eggs eaten, the higher the risk of diabetes" trend.
, correlation is not the same as causation.
, and other large nutrition studies around the world have yet to reach consensus on egg and diabetes risk.
team of authors also suggest that differences observed in different studies suggest that different diets also play a role, not just in the amount of eggs eaten.
the study period, Chinese groups grew more and more abundant, moving from vegetable grains to large fish, oily, high-calorie diets.
In this study, the vast majority (92.9%) of the subjects also increased their overall egg consumption, and the average egg consumption of all subjects nearly doubled from 1991 to 2009 (16 g/day-31 g/day), which is not difficult to speculate that this increase is accompanied by changes in other dietary factors.
addition, data sources, while authoritative, have certain limitations. the
study only tested blood samples in 2009 to assess diabetes status and lacked family history information on diabetes; CHNS subjects reported very low rates and high overall follow-up failure rates between 1997 and 2006; and egg consumption was recorded only seven times using inaccurate methods, and lacked other cooking data.
So, while the study sheds new information through Chinese large-scale data, it is not enough to upend existing perceptions in everyday practice, let synth of understanding that "eating one more egg increases the risk of diabetes by 60 percent."
authors also suggest that a controlled study of egg eating and diabetes risk is still necessary.
other dietary factors that affect diabetes, however, diet does have a small impact on diabetes.
, rather than worrying about the lack of a conclusion and "from the conclusions of a study", it would be better to have clear risk management first.
China's Type 2 Diabetes Prevention and Control Guidelines recommend that the general population should pay attention to a reasonable diet, weight control, moderate exercise, salt restriction, tobacco control, alcohol restriction, psychological balance of a healthy lifestyle.
If you are already in prediabetes, dietary control and exercise should be used to reduce the risk of developing diabetes, with specific targets for risk interventions: (1) overweight or obese people with a BMI of 24 or close to 24, or weight loss of at least 7% ;( (2) Reduce the total daily dietary calories by at least 400 to 500 calories; (3) saturated fatty acid intake accounts for less than 30% of total fatty acid intake; and (4) maintain moderate-intensity physical activity for at least 150 minutes/week.
In addition, attention should be paid to low-sugar, low-salt: control the intake of added sugars, do not drink sugary beverages, salt intake is limited to 6 grams per day, daily sodium intake does not exceed 2000 mg, eat less sodium-containing condiments or foods, such as MSG, soy sauce, seasonings, pickled products, salt immersion and other processed foods.
. How much do you eat with eggs? Diabetes risk aside, cholesterol is one of many people's concerns about eggs.
but similar, and it's a subject that's constantly being studied to provide new evidence, but it's still controversial.
year, the American Heart Association (AHA) published scientific recommendations on dietary cholesterol and cardiovascular risk, noting that, looking back at available evidence, there was no significant correlation between egg intake and cardiovascular risk overall.
considering the high levels of egg yolk cholesterol, it is still recommended that healthy people eat up to one whole egg a day, and patients with abnormal blood lipids should be cautious about eating cholesterol-rich foods.
Chinese Nutrition Society's Dietary Guidelines for Chinese Residents (2016) provide scientific evidence and guidance in line with China's national conditions.
, the guidelines point out that eggs have a wide range of nutrients and high nutritional value, but considering that cholesterol levels are also high, intake should not be excessive.
recommend eating 280g to 350g of eggs per week (about one egg per day) and not discarding egg yolks.
