Although red meat is rich in protein, iron, and other nutrients, a recent research has increased it to the risk of dementia, but some doctors have doubted this statement.
According to a press release, researchers at Harvard University Chen Zengxi School of Public Health and MIT Birgm School found that eating a certain amount of machining red meat daily increased the risk of dementia by 13%.
It is also related to the decline in subjective cognitive capabilities and the risk of accelerated brain aging by 14%.
Studies have found that eating a specific diet can enhance the brain and memory
"This discovery did not really surprise us," Yuhan Li, the main author of the research, and Chen Zengxi University of Public Health, Harvard University in Boston, told Fox News Digital Channel.

"As a result, it is in line with our assumptions, indicating that the intake of red meat is high, especially to process red meat, which is related to the increase in the risk of poor dementia and cognitive ability."
Study articles stated that at least a quarter of people who eat at least one -quarter of unprocessed meat increased. This is equivalent to about one hot dog, two bacon or a half of Bologna.
Nutritionists responded to the ban on red edible dye: "It took too long"
Researchers also suggested that using a nut and beans per day to replace a copy of red meat to reduce the risk of dementia by 19%, and replacement with fish can reduce the risk of 28%.
The study included 133,771 people, of which 11,173 were diagnosed with dementia in four years. These data come from Nurse Health Studies (NHS) and follow -up research (HPFS), which follows the diet and health status of participants.

The research was funded by the National Institute of Health and published on January 15 in the "Neurology" magazine.
The research results were first announced at the International Conference (AAIC) of the Alzheimer Disease Association in early 2024.
"There are many reasons to believe that excessive red meat is related to dementia," "Dr. Mark Siger, a senior medical analyst of the Lamggi Health Center of New York University of New York, told Fox News Digital Media.
"For processed meat such as bacon and ham, the addition of chemicals may also cause dementia through inflammation and neuritis," Stergel added that he did not participate in this new study.

The doctor also warned that red meat may lead to gain and obesity, which causes inflammation, and then increases the risk of dementia.
"Red meat may also cause heart disease, which increases the risk of dementia," Siegel pointed out.
The New York Nutrition and Food Institute, Nutritionist and spokesman, pointed out that previous studies have found that there is a correlation between the risk of red meat (especially red meat) and the risk of type 2 diabetes and cardiovascular disease. Both are related to the damage to cognitive health.
"No food or ingredients ... It has proven to cause, increase risk, prevent, treat, or cure Alzheimer's disease or other dementia."
"This is a long -term large -scale study and adjusted the mixed factors. As a result, it is found that in the three different groups, eating more red meat than eating less red meat and less cognitive ability decreased. Related, "Jentel said that he had no job about the study and told Fox Digital News.
Some experts believe that this risk is more related to ordinary super -processing foods, not related to specific meat.

Dr. Hinem M. Stanard, senior vice president of Medical and Scientific Relationships in the Alzheimer Society of Chicago, pointed out that many studies have shown that more super -processed foods in diet are not good for brain health.
"For example, a report from AAIC 2022 found that people who consume a large amount of super -processed food have fallen faster," Stanard, who has not participated in this new study, told Fox News Digital Channel.
Diabetes and heart disease cases surge -scientists have proposed a key cause
"Daily intake of more than 20% of ultra -processed foods will lead to a decrease of 28% of the overall cognitive score, including memory and language fluency."
Stanard said that a food "unlikely" has a significant beneficial or harmful effect on "Alzheimer's disease like Alzheimer's disease."
"Through strict scientific research, no food or ingredients are proven to cause, increase risks, prevent, treat, or cure Alzheimer's disease or other dementia," she said.
Siger pointed out that this study is observed, which means "unable to conclude."
"We still need double -blind and random trials to get more clear conclusions," he said.

The main study author Yuhan also acknowledged potential limitations.
"Nurse Health Research recruited female registered nurses, and health professionals followed up to recruit American male health professionals," she told Fox News Digital Channel.
Early studies have shown that edible oil is related to colon cancer and inflammation
"These participants often have a high level of education and income level, so the universality of the study may be limited. In addition, because this research is a observation study, there is still a possibility of residual mixed mixed."
Dr. Ken Belry, a family doctor and diabetic expert in Tennessee, did not participate in the study, but shared his views on "healthy user prejudice" that may distort results.
A doctor pointed out in this study: "In these studies, people who eat at least the meat and the least red meat -they also exercise every day." (Istock)
He stated in a video released on the YouTube channel last week: "In these studies, people with the least processing meat and red meat are also exercising every day."
"They never smoke. They don't drink excessive drinking. They are trying their best to live a healthy life."
"We still need double -blind and random trials to get more clear conclusions."
Berry pointed out that research shows that regular exercise and eating natural foods that have not been processed can reduce the risk of dementia.
"I don't think any nutritional experts will oppose this," he said, but added that "no evidence" indicates that red meat is related to higher dementia risks.
Gentile recommends that the amount of red meat such as bacon, sausages, hot dogs, and cooked meat is limited to less than a quarter of the daily, and considers the use of healthier protein substitutes, such as fish, nuts, beans and chicken.

"Balanced diet, appropriate amount of protein sources and portions are the key," Jandiel said. "If your diet contains a large amount of red meat, try to replace one of the foods with beans, fish or chicken."

Nutritionists also recommend foods that promote brain health every day, such as fruits, vegetables, whole grains and healthy fats.
Snead pointed out that the Alzheimer's Club has been encouraging a balanced diet for a long time to help prevent Alzheimer's disease and all other dementia.

"This includes less processed foods to ensure that our body obtains the nutritional nutrition because they are related to the low risk of cognitive ability," she told Fox News Digital Channel.
"As research continues, we may find other diet models that increase or reduce risks."
Berry pointed out that although he claims to be "carnivores", he is not completely "anti -plant".
"I am a supporter of the correct human diet. Its scope ranges from low carbohydrates containing vegetables, berries and nuts to ketones containing some berries, vegetables and nuts, and then to the 'ketone diet of only a little vegetable flavoring and decorative. Until the carnivore, he said in the video.

He said that the best diet of any individual should depend on many factors, including their overall metabolic health, age, weight, genetic and intestinal microbiological group.
Berry added, "This is the correct human diet."
