Consuming a high-fat diet in the 1920s and 1930s increases the risk of poor health later – not just because of weight gain.
According to researchers from Qingdao University, China fatty foods cause the reduction and mutation of so-called "good" bacteria in the gut.
In particular, the unhealthy diet alters microbes – which break down food into the stomach – and causes an increase in inflammatory markers throughout the body.
Data published online in the Gut magazine raise concerns that it may sow the seeds of metabolic disorders such as diabetes, heart disease and stroke in the long run.
to-taste: Researchers from Qingdao University, China, have studied 217 healthy 18-35 year olds
Researchers set out to see whether different levels of fats in food change intestinal bacteria in healthy young people from China
Dietary habits in the Asian country moving from a low fat content high content of carbohydrates to a relatively high fat content and a low carbohydrate content.
Researchers divide 217 healthy 18 to 35-year-old children with normal weight into three dietary groups.
The participants then receive different ratios of carbohydrates – white rice and wheat – and fats – mostly soybean oil
The fiber and protein intake is the same among all participants
The three extreme diets are either low in fat where lipids are formed 20% of the energy of the participants int
Moderate fat – equal to 30% of the energy intake – or high in fat – where the lipids account for 40% of the energy intake.
Each participant sticks to his specific diet for six months. the impact on their intestinal bacteria and markers of inflammation was evaluated in blood and feces samples taken at the beginning and end of the experiment. the most. However, some changes, with potential long-term health effects, are only evident in samples from the high-fat group.
Warning: Data published online in the Gut magazine fear that it may sow the seeds of metabolic disorders such as diabetes , long-term illnesses and strokes
Although there have been no major changes in the total intestinal bacteria volume between the three groups, the number of beneficial bacteria that produce short-chain fatty acids, including butyrate, increases only in the low- fat.
On the other hand, the number of these beneficial bacteria fell into the high fat group.
And the number of "bad" bacteria found in the gut of people with type 2 diabetes, for example, has increased. Statins should be given over 100,000 more in middle age

Health officials demand statins prescribed to 100,000 more middle-aged people to reduce the risk of heart attacks and strokes. 19659002] New targets are being launched by a coalition of organizations to improve the detection and treatment of atrial fibrillation, high blood pressure and high cholesterol – three conditions that are among the major causes of cardiovascular disease and cause one quarter of early deaths in the United Kingdom
Led by NHS England and Public Health England, the goals suggest the number of people believed to be at high risk of cardiovascular disease and treated with statins – which reduce the levels of harmful cholesterol with inf arthritis and strokes – should increase from 35 to 45% – from 400,000 to 500,000 – by 2029.
Duncan Selby, CEO of PHE, said: "Prevention is always better than cure" . Health bosses said they would encourage local authorities to promote the NHS Health Review, a national program offered to all children aged 40 to 74 every five years. The check includes assessment of cardiovascular risk factors such as blood pressure, blood sugar and cholesterol.
The new coalition consists of more than 40 organizations, including the British Heart Foundation, the Association for Stroke and several universities. Some bacteria, such as Blautia – associated with lower cholesterol levels – have been plentiful among low-fat people.
Types of Bacteroides that are associated with elevated cholesterol levels are more common among people with high fat content.
Moreover, the diet with higher fat content is associated with significant and potentially harmful changes in long-chain fatty acids. This leads to higher levels of chemicals believed to cause inflammation. The opposite is true for the low-fat diet
Researchers stress that sampling was done only at the beginning and end of the test.
A more complete picture of microbial changes would appear more frequent.
Since all three groups have lost weight, it's also not clear whether weight loss causes the observed changes or vice versa.
And since participants were young, healthy and of normal weight, the findings
But the conclusions seem to indicate the need to limit the dietary fat, the researchers suggest.
"Compared to a lower-fat diet, the long-term consumption of a higher fat diet seems undesirable …. for young healthy adults whose diet is in a transition from a traditionally consumed diet with a lower fat content, with a higher carbohydrate, to one that is characterized by a significantly higher fat content, "they concluded," consequences for other countries. "
" These findings can also be of importance in developed countries, where fat intake is already high, "researchers said
