### Processed Foods and Health Risks### Processed Foods and Health Risks Excessive consumption of processed foods poses significant health concerns, according to immunologist Professor Luke O’Neill. Studies indicate that highly altered foods increase the risk of certain diseases. Ultra-Processed Foods: Ultra-processed foods contain added oils, flavorings, and colorings, and their convenience comes at a cost. For example, microwave meals and fast food can harm intestinal health. Impact on the Gut Microbiome: Highly processed foods disrupt the balance of bacteria in the gut, damaging the microbiome. Beneficial bacteria produce natural chemicals that protect the gut and suppress inflammation. They also reduce the risk of colon cancer. Altering the microbiome through excessive processed food intake can lead to health problems. Immune System Effects: Processed foods can also impair the immune system. High salt intake, common in processed foods, stimulates immune cells, triggering autoimmune reactions that attack the body’s own tissues. Additionally, too much salt hinders the production of short-chain fatty acids, which suppress inflammation and weaken the immune response. Conclusion: Professor O’Neill emphasizes the importance of reducing processed food consumption to maintain overall health. He advises considering alternative diets and opting for less manipulated foods to minimize the potential health risks associated with excessive processed food intake.
People who eat too many processed foods should consider a new diet, as processed foods can cause cancer and autoimmune diseases.
That’s according to immunologist Professor Luke O’Neill, who said studies suggest the more ‘manipulated’ food is, the greater the health risk.
While most foods are processed to preserve or improve them, ultra-processed foods have more oil, flavorings or colorings added than normal.
Prof O’Neill said Show me the science This food has become more popular because of its convenience – but too much convenience comes with a price.
For example, he explained that a study in France showed that eating too many microwave meals or fast food can be harmful to your intestines.
“These ultra-processed foods and the chemicals they contain are harmful to the gut and in particular to the microbiome,” he said.
“There are trillions of bacteria living in your gut, in your colon, in your intestines, and they are very important to our health. If they get disrupted, it can damage the gut.”
Highly processed foods can damage the microbiome and change the composition of the gut.
According to Prof. O’Neill, these changes in the composition of bacteria in the gut could have consequences for all aspects of health.
“The beneficial effects of these bacteria are that they produce natural chemicals that protect the gut,” he said.
“They prevent your intestines from leaking and no longer leaking into your blood, they suppress inflammation.
“They can also reduce the risk of colon cancer and tumors that grow there. So if you eat too many ultra-processed foods and you change the microbiome, you can get into trouble.”
Processed Foods in the Immune System
According to Prof. O’Neill, too much processed food can also be harmful to the immune system.
A study by Professor Vijay Kuchroo in the US has shown that increased salt intake – a major component of processed foods – stimulates cells in the immune system.
“It turns out that the salt can give them a kick,” he said. “You trigger T-cells to become too active, and your own T-cells start turning on your own body and triggering autoimmune reactions.”
According to Prof. O’Neill, too much salt is also harmful to your gut because short-chain fatty acids can ‘switch off’ the inflammatory part of an immune response, limiting its strength.
