ACER: Diets and Vitamin Intake Do Not Help Reduce Cancer Risk

Taking vitamins and following specific diets does not help reduce the risk of developing cancer or improve the effectiveness of cancer treatment. This conclusion was reached by scientists from Italy. The results of their study were published in the journal Aging Clinical and Experimental Research (ACER).

The researchers conducted a meta-analysis of dozens of clinical and preclinical studies published on scientific platforms such as PubMed and ClinicalTrials. Their analysis confirmed that the unregulated use of dietary supplements can be harmful. Hypervitaminosis, which disrupts the balance of micronutrients, can not only worsen overall health but also stimulate tumor growth. At the same time, there is no solid evidence supporting the benefits of multivitamins in cancer treatment.

The researchers also expressed skepticism about the effectiveness of popular diets — such as keto (high fat, low carbohydrate intake), intermittent fasting, and veganism. While promising results have been observed in animal models, these approaches have not shown convincing outcomes in clinical practice.

The most balanced and safest nutritional strategy, according to the experts, is the Mediterranean diet. The authors believe it provides the body with essential antioxidants, vitamins, and healthy fats. The scientists also emphasize the importance of a comprehensive approach to health — including physical activity and avoiding harmful habits.
