Health risks of dietary beverage and supplement consumption

Medical experts have issued warnings regarding the potential health impacts of various dietary habits and substances. Nephrology specialists, including Prof. Dr. Aydın Türkmen of the Turkish Kidney Foundation, have highlighted risks associated with unregulated herbal teas and dietary supplements. These products, such as green tea, hibiscus, licorice, and senna, may affect blood pressure, potassium levels, and fluid balance. There are also concerns regarding contamination from heavy metals, pesticides, or undeclared pharmaceutical ingredients.

Research has also linked certain artificial sweeteners, such as aspartame, saccharin, and erythritol, to an increased rate of cognitive decline. Additionally, experts warn that consuming tea at excessively high temperatures may irritate the esophagus, while over-brewing tea can increase levels of tannins and fluoride, potentially affecting kidney and digestive health.

Regarding coffee, studies suggest that while morning consumption may be associated with lower mortality risks, individual effects vary based on caffeine sensitivity and preparation methods.
