Red meat, consumed mainly for its iron content, can be equally harmful. New research presented at the Alzheimer’s Association International Conference in the US revealed that consuming processed red meats like bacon, hot dogs, sausage, and salami may raise the risk of developing <a href="https://www.healthandme.com/health/dementia">dementia</a>. The study tracked over 130,000 people for up to 43 years and found that more than 8% of participants developed dementia. Those who consumed around two servings of processed red meat per week had a 14% higher risk of dementia compared to those who ate fewer than three servings per month.

Dementia is a term for a range of symptoms affecting memory, thinking, and social abilities to the extent that it disrupts daily life. It is commonly caused by Alzheimer's disease and other neurological disorders. While this disorder is generally associated with older age, there is a new trend of younger onset dementia affecting people as early as 30 years old.

Meanwhile, the research also highlighted that substituting processed red meat with nuts and legumes, such as beans and peas, could lower dementia risk. Replacing a daily serving of processed red meat with nuts, beans, or tofu was associated with a 20% reduction in dementia risk. "We discovered that long-term consumption of processed red meat could significantly increase dementia risk," said Yuhan Li, the study’s lead author and a research assistant at Brigham and Women’s Hospital. Processed red meats are considered ultra-processed foods, which include additives like high-fructose corn syrup and artificial substances. These types of foods, along with chips, ice cream, and instant soups, are linked to various health issues, including type 2 diabetes, heart disease, and obesity.

The study found that the saturated fat, sodium, iron, and nitrites in processed red meat contribute to higher risks of stroke, chronic inflammation, high blood pressure, and neurological disorders. Additionally, processed red meats are known to increase the risk of cancer, heart disease, and diabetes due to harmful substances like nitrites and sodium.

For the study, participants' diets were assessed every two to four years using questionnaires. Among the 130,000 participants, over 11,000 developed dementia. The study noted that higher daily consumption of processed red meat was associated with cognitive decline, while eating nuts and legumes was linked to less cognitive decline as people age. Interestingly, no significant link was found between unprocessed red meat, such as hamburgers and steak, and dementia. Notably, previous research in the UK and Brazil had similarly associated ultra-processed foods with dementia and rapid cognitive deterioration.
