Friends who love to eat fried food must have encountered this situation: after frying food is still left a lot of oil, so much oil directly thrown away will feel very wasteful, so many people choose to store it to save for later cooking and then use. This method sounds quite good, not only to prevent waste but also can not because frying food once and consuming a lot of oil. However, this method is more economical, but it is likely to be bad for your health.

Recently, there was an interesting study that found that rats that ate food fried in second-hand oil every day, and their babies, seemed to become less intelligent! This is just like how we humans eat fried food from street stalls every day, and we find that not only do we become slow, but even the next generation is affected. Why is that? It turns out that it has something to do with the kind of oil that is used over and over again.

Did you know that this kind of oil interferes with the "communication" between our liver, intestines and brain? It's like when we make a phone call and the signal is bad and we can't hear what the other person is saying, and the same goes for all these organs in the body, if they don't communicate well, something will go wrong. To figure this out, scientists experimented. They divided the mom rats into groups, some were given just normal food, some had a bit of fresh oil added to their food, and some had the kind of oil that you fry things in over and over again. After 30 days of this, it was found that the moms and their babies who ate the "second-hand oil" became more prone to brain problems.

So how should we actively learn to protect ourselves in this situation or what can fried lovers do to stay healthy? Researchers have recently found that omega-3 fatty acids, curcumin, and ghrelin in nutritional supplements may have a positive effect on reducing inflammation and neurodegenerative changes in the liver. omega-3 fatty acids act as our body's "peacemakers," helping to calm inflammatory storms in the liver and maintain harmony and balance in our bodies. harmony and balance in our bodies. Curcumin and ghrelin, on the other hand, act as "guardians" that silently protect our nervous system from degenerative changes that lead to ageing. However, the researchers also emphasized that these findings are still mainly at the experimental stage, especially in rats. For humans, more clinical studies are needed to verify whether these nutraceuticals can combat the adverse effects of fried foods.

After all, those aromatic fried foods, especially those made with repeatedly used oils, may be quietly causing harm to our bodies. And nutraceuticals, while they may have some protective effects, cannot completely replace the importance of a healthy diet and lifestyle.

Future researchers will be embarking on a new journey of discovery about the repeated use of oil, as they want to unravel the mystery of the link between refried oil and several diseases and to see what effects this common cooking method has on our brains. They'll also be looking at whether deep-frying oil can make us anxious, depressed, or exacerbate neuroinflammation. On top of that, they have the bold idea of delving into the delicate relationship between the gut microbiome and the brain. After all, there are so many tiny "gremlins" in the gut that could be inextricably linked to the human brain. Through this research, researchers hope to find new ways to prevent or treat neurodegenerative diseases and neuroinflammation, so that we can live healthier, happier lives.
