Why Cookies and Other Sugary Treats Are Bad for a Fever
When your body is fighting off an infection, your immune system is working in overdrive and requires optimal fuel to function efficiently. Unfortunately, the refined sugar and high fat content in cookies and other processed snacks do the opposite.
Suppressed Immune Function
Research indicates that consuming high levels of sugar can hinder the effectiveness of white blood cells, which are critical for fighting off the germs causing your illness. The effect can last for several hours after consumption, leaving your immune system compromised when it needs to be at its strongest. Sugary foods offer zero immunity value, providing empty calories instead of essential vitamins and minerals.
Increased Inflammation
Excessive sugar consumption can increase inflammation in the body. For someone with a fever, whose body is already under stress from fighting an infection, adding more inflammation is counterproductive. The body's priority should be recovery, and inflammatory foods only hinder that process.
Digestive Strain
Illness, especially with fever, can weaken your digestive system. Cookies are often high in refined carbohydrates and fats, making them heavy and difficult for a compromised digestive system to process. This can lead to bloating, discomfort, and a slower recovery. As noted in Men's Health, refined sugar can pull fluid from the GI tract, potentially worsening diarrhea if you have a stomach bug.
The Importance of Hydration and Nutrient-Dense Foods
With a fever, your body loses fluids more rapidly through sweating. Proper hydration is vital for regulating body temperature, flushing out toxins, and ensuring your immune cells can function effectively. While sugary sodas and sports drinks might seem appealing, their high sugar content can worsen dehydration and offer little benefit.
What to Choose Instead
To support your recovery, focus on easily digestible, nutrient-rich foods and hydrating fluids. Good options include:
- Broth-based soups: A classic for a reason, chicken or vegetable broth helps with hydration and provides essential electrolytes and nutrients.
- Fresh fruits: Fruits like watermelon, cantaloupe, and oranges are high in water and packed with immune-boosting Vitamin C.
- Herbal tea with honey: Warm, decaffeinated herbal tea can soothe a sore throat, and a little honey has antimicrobial properties, but limit the sugar.
- Popsicles (without high sugar): For children or those with a sore throat, low-sugar or fruit-based popsicles can provide fluids and soothe discomfort.
- Toast and crackers (simple carbs): When your appetite is low, bland options like toast or simple crackers can be easier on the stomach and provide a simple energy source.
Cookies vs. a Healthy Alternative
| Trait | Cookies (Refined Sugar) | Fruit Smoothie (Healthy Alternative) |
|---|---|---|
| Immune Impact | Suppresses white blood cell function. | Boosts immunity with vitamins, especially C. |
| Inflammation | Can increase inflammation in the body. | Contains antioxidants that reduce inflammation. |
| Digestibility | Heavy and hard to digest, straining the body. | Easy to digest; can be a low-effort source of calories. |
| Hydration | Provides no hydration; may worsen dehydration. | Often made with hydrating fluids like water, milk, or coconut water. |
| Nutritional Value | Provides empty calories with minimal nutrients. | Delivers vital nutrients and hydration to the body. |
Conclusion: The Right Fuel for Recovery
When you are ill with a fever, your body's energy is channeled into fighting the infection. Consuming sugary, high-fat foods like cookies diverts energy toward digestion and can suppress the immune response, extending your recovery time. A better approach is to provide your body with the nutrients and hydration it needs to fight back effectively. Prioritize nourishing options like broths, fresh fruits, and herbal teas. While a cookie might offer momentary comfort, a healthier diet will help you feel better and get back on your feet faster.
