What is the estimated death toll from COVID-19, and what ongoing challenges does the virus pose to global health?

Five years after the start of the COVID-19 pandemic, over 20 million deaths are estimated, with the actual number potentially three times higher than officially reported. Scientists developed vaccines in record time, saving millions of lives, though the virus continues to evolve, requiring updated vaccines. The Omicron variant, and its subvariants, currently dominates, causing less severe illness than previous strains.

How do the protective effects of the recommended foods relate to the rising rates of early-onset colorectal cancer, particularly in young people?

Studies show a correlation between increased consumption of these foods and a reduced risk of colorectal cancer. For example, whole grains and legumes are linked to a 17% and 21% lower risk, respectively. The protective effects are attributed to various bioactive compounds like antioxidants, fiber, and phytonutrients, which combat inflammation and reduce the risk of tumor growth. Increased intake of coffee and tea has also demonstrated positive impacts.
