Bell peppers may support immune health during 'super flu' surge

CDC data shows the H3N2 subclade K 'super flu' is circulating widely with rising test positivity and hospitalisations, and experts note red bell peppers contain higher vitamin C and antioxidants than other pepper colours.

CDC reports that the H3N2 subclade K strain of influenza, referred to in some coverage as a 'super flu,' is circulating with rising test positivity and increased hospital admissions. Annual flu vaccination is described in the article as the primary prevention measure. Nutrition experts and dietitians cited in the report say foods high in vitamin C and antioxidants can support immune function, and bell peppers are highlighted for their nutrient content. Red bell peppers are reported to have higher levels of vitamin C and antioxidants than less ripe peppers, and cooking method can influence how much vitamin content is retained. Reported details: - CDC data cited in the article indicated 'very high' influenza activity in many states and a rise to about one in three tests returning positive in late December. - The article reports hospitalisation rates increased by about 54% in one week, based on the cited figures. - The report states that annual flu vaccination remains the main prevention strategy according to public-health guidance mentioned. - Nutrition experts in the article say red bell peppers contain substantially more vitamin C and antioxidants than green peppers, and that gentler cooking methods like steaming or stir-frying help preserve water‑soluble vitamins. Summary: Rising test positivity and hospitalisations reflect active circulation of the H3N2 subclade K season and are being tracked in public-health reports. Undetermined at this time.
