Long-term studies: Vegetable proteins are much healthier than animal ones
People who want to lose weight are often advised to eat protein-rich foods. Eventually, protein will melt the pounds. But protein is not all protein: two long-term studies have now shown that a high proportion of animal proteins increases the risk of death. Those who eat vegetable protein are therefore significantly healthier.

Vegetarian diet is healthy
Meat-free diet is healthy: Only recently did scientists report in the journal The Journal of the American Osteopathic Association that life expectancy of vegetarians has increased. They live almost four years longer than meat consumers. US researchers have now also found that plant-based foods are healthier. According to her, the consumption of animal proteins increases the risk of death.

Intake of animal proteins increases the risk of death
According to the scientists led by Mingyang Song from the Harvard Medical School in Boston, Massachusetts, USA, two long-term studies showed that the intake of animal proteins was associated with a higher risk of death than that of vegetable proteins. The researchers have now published their results in the specialist journal "JAMA Internal Medicine". Song, a research associate at the Massachusetts General Hospital (MGH), said in a clinic announcement, "While previous studies have primarily focused on total protein intake," our results also have "public health implications."

Recommendations for protein intake
They can help “refine current recommendations for protein intake, especially considering that not only the amount of protein is important, but also the specific food sources that are critical to long-term health.”

Earlier studies had shown that replacing carbohydrates with proteins was healthy. In the current study, the main sources of animal protein were processed and unprocessed beef and pork, chicken, dairy, fish and eggs. The vegetable protein came mainly from bread, cereals, pasta, nuts, beans and legumes.

Data from two long-term studies evaluated
To arrive at their results, the researchers used data from two long-term studies that recorded the health and eating habits of healthcare professionals. A total of 85,013 women and 46,329 men were evaluated. The data came from 1980 to 2012.

Every two years, the test subjects had to use a questionnaire to report on their lifestyle and health, and every four years they had to report in detail on the foods they ate on average. During the investigation period, 36,115 of the participants died, 8,851 from cardiovascular diseases, 13,159 from cancer and 14,105 from other causes.

Pronounced relationship among overweight people and alcohol users
During the evaluation, the scientists found a relationship between the amount of animal protein consumed and the risk of death. According to the information, the connection was particularly pronounced among overweight people and people who drank a lot of alcohol. The experts also calculated how the increase and decrease in animal and vegetable proteins in the diet affects the risk of death. After adjusting the lifestyle risk factors such as smoking, alcohol consumption and obesity, it was found that the risk of death increases by two percent if the proportion of animal protein increases by ten percent in relation to the total calorie intake.

The risk of dying from cardiovascular disease increases by as much as eight percent. In contrast, the risk of death is reduced by ten percent if three percent more vegetable protein is included in the diet.

Fish and chicken are better choices
The relationship became even clearer when animal proteins were partially replaced by plant proteins. The conversion of processed beef and pork such as sausages and eggs to vegetable proteins was particularly worthwhile. "Our results suggest that people should consider eating more vegetable protein, and if you choose from animal protein sources, fish and chicken are probably better choices," Song said.

"Health risk when eating meat"
According to a report by the APA news agency, the study result for Heiner Boeing from the German Institute for Nutritional Research in Potsdam-Rehbrücke is not surprising. This confirms the research with long-term data in which his institute is involved.

"Two well-known long-term studies represent the basics and the statistical analysis and evaluation have been carried out very carefully," said Boeing. "The study shows that plants are a very good source of protein and that there is also a health risk in meat consumption in addition to the ecological problems of meat production."

High protein intake for weight loss
Bernhard Watzl from the Max Rubner Institute, Federal Research Institute for Nutrition and Food in Karlsruhe also considers the underlying surveys to be “scientifically very well done”, but it is questionable whether the results are transferable to the general population, since all subjects in the medical environment are employed. “At the moment, some experts recommend a high protein intake, among other things as a measure for weight loss. However, the long-term effects of such a diet are not known. ”The study now gives important indications of health differences between the different protein sources.

More and more vegetarian foods on offer
The market share of meatless foods continues to increase: vegan or vegetarian foods are taking up more and more space on the shelves of German supermarkets. "The market is booming and there is no end in sight," says the Cologne Institute for Trade Research (IFH). But not only vegetarians and vegans buy the meatless products. "The real bearers of the veggie boom in Germany" are the so-called flexitarians, according to the Gesellschaft für Konsumforschung (GfK). Years ago, around ten percent of Germans were classified as flexitarians.

The last generation that has meat on the table every day
Meat consumption has generally decreased among many consumers in recent years. The health aspect is often in the foreground. A meat-rich diet, for example, leads to an increase in the formation of uric acid in the body, which in the long term can lead to kidney stones or gout in some people. In addition, studies indicated that excessive consumption of red meat increases the risk of developing colon cancer or heart attack.

Meanwhile, more and more sausage and meat products producers are discovering the market for themselves and expanding their product range with meatless variations. According to APA, the owner of the sausage manufacturer Rügenwalder, Christian Rauffuss, said: "We will probably be the first and last generation to have meat on our plates every day." (Ad)
