As the temperatures in the UAE begin to dip, many residents are gravitating toward their favorite comfort drinks like karak tea or flocking to pharmacies to stockpile vitamin C, zinc, and various immunity boosters. However, experts warn that this seasonal ritual may be based on a misunderstanding of how the human immune system actually functions. Nada Zuhair Ahmad Al Adeeb, Secretary General of the UAE Nutrition Society, notes that while supplements are popular, they are often used as a "shield" against illness, which is not supported by scientific evidence. Instead of relying on pills or sugar-heavy tea, she emphasizes that real health resilience begins in the kitchen.

The core of the issue lies in poor daily nutrition; the UAE National Health Survey revealed that a vast majority of residents fail to consume the World Health Organisation's recommended five portions of fruits and vegetables daily. Al Adeeb explains that the immune system requires a complex synergy of nutrients found in whole foods—such as folate from leafy greens, protein from legumes or lean meats, and carotenoids from colorful vegetables—which cannot be replicated by a single pill. While ingredients like honey and ginger can soothe symptoms, they shouldn't replace a balanced diet. Ultimately, the best way to stay healthy this winter isn't through a supplement aisle, but by ensuring you are well-hydrated, prioritizing consistent sleep, and consistently hitting those daily vegetable targets.
