Clearly in a survey over 22 years that high-protein diet increases the risk of heart disease in both meat and dairy products, what is a protein not related to heart disease risk?

"High-protein diet" has attracted attention from people with high health consciousness, but on the other hand, taking a large amount of proteins, especially animal protein, from past studies has the risk of raising the risk of type 2 diabetes and death Was shown. So the research team headed by Associate Professor Jyrki Virtanen who studies nutritional epidemiology at the University of Eastern Finland, does the high protein diet really benefit people's health? We conducted research to investigate the fact. As a result, it has been shown that the risk of heart failure increases if vegetarian ingest more vegetable protein.

In the research, an average 22-year follow-up survey was conducted for 2441 men aged 42 to 60.In 1984When I started the research, the subject answered the questionnaire "What did you eat on the 4th day before the start of the study?", And from there it was divided into 4 groups for each protein intake. There are 334 cases diagnosed as heart failure during the study, researchers are related to which group and heart failure, and whether there is a relation between protein type and heart failure I examined.

When group taking the average of 109 g of protein per day is classified as "group with the most protein intake", group taking on average of 78 g of protein per day is defined as "group with the least protein intake" It was found that the risk of heart failure is 33% higher in the group with more protein than in the less group. Furthermore, looking closely at the comparison of these two groups, it was said that the risk of heart failure was high in 43% of the group taking a lot of animal protein and 49% of the group taking protein from dairy products. Although the group taking a lot of vegetable protein also had a high risk of heart failure, the difference is 17% and Forbes pointed out that it is not statistically significant difference.

Also, the relationship between heart failure and the group ingesting proteins from fish and eggs has not been confirmed. In a study conducted by Chinese research team on 400,000 adults on May 21, 2018 "One egg per day may reduce the risk of cardiovascular disease"This research also supported this result. Also included in fishω-3 fatty acidThere is also a report to lower the risk of ischemic heart disease.

However, it is pointed out that this study focuses on the subjects being limited to men, the fact that only one visit was made on dietary habits, and the conclusion is limited due to the small scale of the research It has been.

There is also a difference in the amount of protein ingested by country, region and gender, and the amount of protein intake per day for Finnish inhabitants who are subjects of this study is 107 g per person, in the case of Japan it is 114 g, in the case of Japan It is said that it is 92 g.

Daily Protein Intake Per Capita

ProteinRecommended dietary allowanceIs0.8 g per kg body weight, That is, 40 g for a person weighing 50 kg and 48 g for a person with 60 kg. In other words, the state that it is ingesting nearly 100 g is taking protein twice the recommended amount. However, since the amount of protein per egg is about 7.4 g, the amount of protein per 100 g of wagyu thigh meat is 21.3 g, etc., depending on the style of eating habitsWe have not reached the required protein amount per dayThere should be people, too.

The amount of protein contained in food can be examined from the following website.
