Animal protein is not associated with increased risk of death

A new study that follows nearly 16,000 American adults found that animal protein consumption is not associated with increasing the risk of death from any cause, including heart or cancer.

Unlike previous research, the study discovered a modest protective effect against cancer deaths from animal protein, with a high consumption associated with a dose -dependent decrease in the risk of cancer death.

The researchers attribute the contradictory results to a tougher methodology, using advanced statistical modeling on the same government data to provide a more accurate picture of long -term protein.

The study did not find any connection between the IGF-1 (which increases with protein intake) and the risk of death, undermining a long-term biological theory of how the animal protein is harmful.

The analysis provides an accurate vision, noting that it does not study comprehensive nutritional patterns or distinguish between treated and non -equipped meat, but it concludes that mild consumption of animal protein is not dangerous and may be part of a balanced diet.

A new new study concluded Animal protein consumption is not associated with an increase in the risk of death from cancer, heart disease, or any other cause.

The research, which follows nearly 16,000 American adults for up to 18 years, discovered a sudden and humble realistic effect against cancer deaths from animal protein. This analysis, published in the magazine Applied physiology, nutrition and metabolismShe directly challenges the 2014 study, which has been greatly announced and controversial, which helped fuel the global movement based on the plant by claiming that meat consumption has greatly increased the risk of cancer.

The study was led by researchers from McMaster UniversityWho analyzed data from a representative group at the national level of 15,937 adults between 19 years and over. The researchers follow nearly 4000 deaths between 1988 and 2006. The methodology was a major force; Unlike many nutrition studies that depend on the memories of the participants sometimes on their diet, this analysis used advanced statistical modeling to estimate the usual protein intake in the long term, providing a more accurate picture of consumption habits.

The basic results were clear and reassuring for those who include meat, dairy and eggs in their diet. The data did not show any evidence that people who consumed animal protein were more likely to die from any reason. This is a contract for public deaths and l Specified deaths to cardiovascular disease. The amount of vegetable protein has shown a similar neutral pattern, not providing any clear benefit to survival but also no harm to this data set.

The most interesting result appeared when the researchers isolated cancer deaths. Unlike the prevailing wisdom, a higher amount of animal protein is associated with a decrease in the risk of death from cancer. The preventive effect depended on the dose, which means that the benefit grew with increased consumption. The analysis found that individuals who consumed only half an ounce of an animal protein per day witnessed a decrease of approximately 20 percent for the death of cancer. Those who consumed an ounce showed more than 40 percent decrease in risk. The plant protein did not show any statistically significant effect on cancer death rates in either direction.

The methodology explains different conclusions

The direct contradiction of this study of the 2014 worrying research asks the question: Why are such different results? The answer lies in design and analysis. The previous study often divides the participants into wide groups such as “LOW” against “high protein food”, an approach that can distort results. Check this new analysis the full spectrum of eating protein continuously and uses advanced modeling techniques to calculate common errors in food measurement. It is worth noting that this has re -analyzed the basic government data set – the third survey of the National Exponation of Health and Nutrition (NHANES III) – But with strict statistical methods.

The 2014 study claimed that people between the ages of 50 and 65 were eating protein four times more It is likely to die from cancer. This new investigation did not find any danger in that age group. In fact, the same modest preventive effect is observed in all age groups of adults.

The researchers have also investigated a biological mechanism that is often blamed at the risk of alleged protein: IGF-1. This hormone, which is increasing in response to protein consumption, was essential for the hypothesis that it works as a meal of cancer. However, this study did not find any relationship between IGF-1 levels and the risk of death from cancer, heart disease or any other cause. This lack of a more link Lose a long -term theory on how animal protein damage.

Context and restrictions: an accurate point of view

Despite its strong results, this study is not a recommendation to consume unlimited amounts of meat. The research examined protein sources in isolation, not comprehensive food patterns. Vegetable diets are rich in fiber, Other useful antioxidants and compounds This study was not measured. Moreover, the analysis did not distinguish between different types of animal protein, such as processed meat such as bacon and sausage – which other strong studies have been associated with negative health results – and not equipped meat such as chicken breast or a steak.

“A balanced diet for optimal health includes a variety of foods from all the main food groups: fruits, vegetables, whole grains, and healthy proteins free of fat and healthy fat,” Brighton of artificial intelligence ENOC said. It focuses on consuming the sizes of the appropriate parts to meet your body’s needs and reject them while reducing processed foods, added sugars and unhealthy fats. This approach guarantees you obtaining essential vitamins, minerals and other nutrients required for your body to work effectively and maintain well -being.

This large -term study provides fundamental evidence that for the general population, Consuming typical amounts of animal protein does not shorten the average life expectancy It has provided a degree of protection against cancer deaths. It is a strong corresponding point for previous anxious addresses and confirms that nutrition science is rarely black and white. The results indicate that the balanced diet that includes a variety of protein sourcesand Without fear or doctrine, the most rational approach to eating in the long run may be. The research confirms that when it comes to protein, the source may be much lower than the quality of the general diet and lifestyle.
