Healthy Things That Are Really Unhealthy
In this short YouTube segment, Nick Norwitz debunks three common health myths. He explains that red wine’s touted anti‑aging benefit from resveratrol would require an impractically large—and lethal—amount of wine to achieve any effect, making it detrimental to longevity. He then argues that mouthwash, while providing fresh breath, kills oral bacteria that produce nitric oxide, a molecule essential for blood‑vessel dilation, and cites human studies showing mouthwash can raise blood pressure as much as exercise lowers it. Finally, he critiques instant flavored oatmeal, noting that despite its “healthy” marketing, the added sugars turn it into a rapid‑release carbohydrate that spikes blood glucose, especially for non‑athletic individuals. Norwitz ends by inviting viewers to suggest other examples of misleading health foods or practices.
