[메디컬투데이=이승재 기자] Research results have shown that the ketogenic diet is effective in preventing lung cancer.
The results of a study investigating whether the keto diet has an effect on suppressing lung nodule formation in mice were published in “Scientific Reports.”
Recently, the keto diet has become popular as a type of healthy diet. The keto diet is a low-carb, high-fat diet and aims to cause “ketosis,” a metabolic state that uses fat rather than glucose for energy.
Previous studies have shown that the keto diet is helpful in managing epilepsy, diabetes, and obesity. Recently, as it has become known that carbohydrate restriction can inhibit the growth of cancer cells, active research is being conducted to test whether the keto diet can prevent various cancers.
Researchers studied the effect of the keto diet on inhibiting tumor cell growth in mice that developed lung cancer through a specific process.
They caused lung nodules to form in mice with nicotine-derived nitrosamine ketone (NNK). Next, the effects of the keto diet were studied by having participants follow seven different diets, including the keto diet, for five months.
The study results showed that regardless of the type of fat, the keto diet was more effective at suppressing lung nodule formation than a Western diet or a diet containing 15 percent carbohydrates. Among keto diets, the fish oil-based keto diet, rich in omega-3 fatty acids, was particularly effective at suppressing the formation of lung nodules.
The researchers reported that omega-3 fatty acids such as EPA, DPA, and DHA were effective in preventing lung cancer nodules. However, since the findings were conducted in mice, further research is needed to determine whether they can be applied to humans.
