Research indicates that a proper diet can significantly lower the risk of dementia, cancer, and heart diseases.
MIND Diet Reduces Dementia Risk by 35 Percent
A long-term study conducted by the University of Ljubljana provides new evidence of the protective effects of the MIND diet. Published in July 2026 in the journal JAMA Network Open, the study followed over 1,800 adults aged 60 and older for more than 15 years.
The findings revealed that individuals who consistently adhered to the MIND diet lowered their dementia risk by up to 35 percent. General anti-inflammatory dietary strategies were associated with a risk reduction of 21 to 29 percent. This effect was particularly pronounced in individuals with elevated pTau217 biomarkers in their blood.
Diagnostic techniques have also progressed significantly. As of July 2026, pTau217 blood tests are clinically available in the EU, provided by manufacturers like Roche, Fujirebio, and Beckman Coulter. These tests can detect dementia with over 90 percent accuracy and cost between €100 and €150.
Kimchi, Kefir, and Yogurt: Natural GLP-1 Boosters
Fermented foods are gaining increasing attention in research. Kimchi, kefir, and yogurt stimulate the production of endogenous GLP-1, the same signaling molecule used by modern weight-loss injections. A review published in the Journal of Food Science in 2025 confirmed the potential of these foods in addressing obesity and inflammation.

More specifically regarding colon cancer, data from the NHANES study, published in 2026 in the journal Nutrition & Diabetes, shows a clear connection. Regular consumption of yogurt and prebiotics halved the likelihood of having a history of colon cancer among over 9,000 adults studied.
In Germany, the incidence of colon cancer among young adults aged 20 to 29 is increasing by more than three percent annually, a trend that has been rising since 2003. Thus, preventive dietary approaches are becoming increasingly significant.
Oxalic Acid: An Overlooked Inflammation Trigger
Not all foods are equally beneficial. A study in Cardiovascular Research identified oxalic acid in 2026 as a potential trigger for systemic inflammation. Oxalate activates the cytokine IL-17A, which is particularly dangerous for patients with chronic kidney diseases, leading to cardiorenal damage.
The German Nutrition Society has recommended at least 30 grams of fiber daily since early 2026. The European Food Safety Authority has recommended 250 mg of the Omega-3 fatty acids EPA and DHA per day since 2010.
Creatine Against Cancer: Focus on Immune Cells
Researchers at UCLA discovered an astonishing effect in July 2026: creatine improves the energy supply of dendritic immune cells. In mouse models, this slowed the growth of specific tumors, such as melanomas. However, clinical studies on humans are still pending.

Fatty Liver and Crohn’s Disease: New Genetic Insights
Over 20 million people in Germany have fatty liver disease. Therefore, the German Society for Gastroenterology advocates for the integration of structured liver diagnostics, such as FIB-4 screening, into regular health check-ups.
In the case of Crohn’s disease, researchers at the Wellcome Sanger Institute identified a gene variant (HLA-DRB1*01:03) associated with particularly severe forms of the condition after analyzing over 43,000 patients. Personalized nutrition involving at least 30 different plants per week lowered hospitalization rates by 31 percent in this context.
Sugar Tax by 2028: €170 Million in Savings
Alongside medical insights, health policy measures are coming into focus. The sugar tax announced for 2028 in Germany could save health insurers up to €170 million per year, by reducing diet-related inflammatory diseases.
