Doctors examined whether "health food products" are truly beneficial.

According to previous studies, the Mediterranean diet, which is primarily based on fish and fresh vegetables, is considered optimal. One recent study revealed that a vegan diet may be even more beneficial, although it is not suitable for some individuals. Medical professionals recommend consuming sugars from natural sources (fruits, honey, dairy products, but not confectionery and granulated sugar), and obtaining micronutrients from food rather than dietary supplements.

Researchers from the University of Tokyo conducted a study to determine whether nutrient deficiencies can be mitigated by foods rich in protein, vitamins, and minerals. The scientists also compared the effects of "healthy food" on its own and in conjunction with dietary supplements. The findings were published in the scientific journal BMC Nutrition.

The study involved 392 healthy Japanese adults aged between 20 and 69 years. Among them, 122 individuals were categorized as consuming fortified foods or dietary supplements, as at least one of these components appeared in their diet at least once during a four-day dietary assessment period. Dietary data for all participants were collected from February to March in 2013.

Analysis showed that the nutrient levels in the bodies of individuals who periodically consumed proteins, vitamins, and minerals from specialized foods or supplements were closer to the norm than those whose diets consisted solely of regular foods without supplements. However, it is important to remember that enriched products should not be overconsumed, and many dietary supplements can pose health risks when used without a doctor's prescription.

The authors of the study also emphasized that while nutrient-dense foods and supplements can help reduce deficiencies of essential elements in the body, they may lead to excessive intake of vitamin B6. This risk was identified in 2% of participants whose diets included "healthy eating products" or supplements.
