Does Eating Sweets Help with Sickness?

4 min read

According to research published in the American Journal of Clinical Nutrition, high sugar consumption can weaken the body's white blood cells, which are crucial for fighting infection. So, while you might crave a sugary treat when you're under the weather, it's worth asking: does eating sweets help with sickness?

Quick Summary

This article explores the science behind sugar cravings during illness and reveals how excess refined sugar can negatively impact the immune system, increase inflammation, and hinder recovery. It also provides a guide to smarter food and drink choices for when you're sick.

Key Points

  • Cravings are physiological: When sick, your body craves sugar for a quick energy boost to fuel the immune system, and sugary foods trigger 'feel-good' brain chemicals.

  • Excess sugar suppresses immunity: High intake of refined sugar can impair white blood cell function and weaken your body's ability to fight off infections.

  • Sugar increases inflammation: Over-consuming sugar can raise inflammatory markers in your body, potentially worsening cold and flu symptoms.

  • Smarter sweet alternatives exist: For soothing a sore throat or settling a stomach, opt for honey in tea, fresh fruit, or ginger candy over processed sweets.

  • Focus on nutrient-rich foods: Prioritizing whole foods like fruits, vegetables, and lean proteins ensures your body gets the essential nutrients needed for recovery, unlike the 'empty calories' in sweets.

  • Proper hydration is key: Avoid dehydrating beverages like sugary sodas and focus on water, broth, and herbal teas to stay hydrated, especially when battling a fever.

The Allure of Sweet Cravings When You're Sick

When illness strikes, many people find themselves reaching for comfort foods, and sugary sweets often top that list. This isn't just a mental desire; it's a physiological response orchestrated by your body and brain.

The Immune System's Energy Demand

When your body's immune system gears up to fight an infection, it requires a significant amount of energy. The metabolic rate increases, and the body seeks out quick, easy-to-digest fuel sources to meet this heightened demand. Refined carbohydrates and sugars provide a rapid release of glucose, offering a temporary energy boost.

The Brain's Reward System and Mood

In addition to energy needs, the brain's reward system plays a big role. Consuming sugar can trigger the release of 'feel-good' neurotransmitters like dopamine and serotonin. This creates a temporary feeling of comfort and pleasure, which can be particularly appealing when you are feeling unwell and low on energy. Stress hormones like cortisol, released during illness, can also drive cravings for high-calorie, comforting foods.

The Negative Impact of Excess Sugar

Despite the tempting comfort, indulging in too many sugary treats can be counterproductive to your recovery. The initial boost is often followed by a slump, and excessive consumption can actively work against your immune system.

  • Impaired White Blood Cell Function: Studies have shown that a high intake of refined sugar can suppress the immune system. It may reduce the ability of white blood cells to fight off bacteria and viruses, potentially prolonging your illness.
  • Increased Inflammation: Excessive sugar consumption can increase inflammatory markers in the body. Since many illnesses are characterized by inflammation, adding more fuel to the fire can worsen symptoms.
  • Nutrient Displacement: When you fill up on calorie-dense but nutritionally-empty sweets, you are less likely to consume nutrient-rich foods that actually help your body heal. Your body needs vitamins, minerals, and antioxidants from fruits, vegetables, and whole foods to recover properly.
  • Gut Microbiome Disruption: A diet high in added sugars can alter the balance of beneficial bacteria in your gut. A healthy gut microbiome is essential for a robust immune response, and its disruption can impede recovery.

Comparison: Sugary Sweets vs. Healthy Alternatives

Feature Sugary Sweets (Candy, Soda, Cookies) Healthy Alternatives (Fruit, Honey, Herbal Tea)
Energy Boost Rapid, but short-lived spike followed by a crash. Slower, more sustained energy release.
Immune System Impact Can suppress white blood cell function and increase inflammation. Supports immune function with vitamins, minerals, and antioxidants.
Hydration Often dehydrating, especially sugary sodas and drinks. Can be hydrating (herbal teas, fruit, honey in tea).
Nutrient Value Low to none (empty calories). Rich in essential nutrients needed for recovery.
Digestive Impact Can upset the stomach, especially with nausea. Gentle on the stomach; options like the BRAT diet (bananas, rice, applesauce, toast) are recommended for nausea.

Smarter Ways to Indulge Sweet Cravings When Sick

If you're looking for a sweet treat that won't hinder your recovery, several healthier options can satisfy your craving while providing some benefit. Here are some examples:

  • Honey: Adding a spoonful of honey to a warm cup of herbal tea can be soothing for a sore throat. Honey also has antimicrobial properties.
  • Fresh Fruit: Fruits contain natural sugars alongside fiber, vitamins, and antioxidants. A fruit smoothie or a cup of berries can be a nutritious and delicious choice.
  • Popsicles: For a sore throat, a fruit-based popsicle can be very soothing. Look for options made with real fruit and no added sugar.
  • Ginger: Ginger is a well-known remedy for nausea. Sucking on ginger candy or drinking ginger tea can help settle an upset stomach, providing a sweet and spicy kick.
  • Yogurt: Greek yogurt with fruit can provide protein and probiotics, which support gut health.

Conclusion

While the craving for sweets when you're sick is a real and understandable physiological response, giving in to a high-sugar diet can do more harm than good. Excess refined sugar can suppress your immune system, increase inflammation, and displace the vital nutrients needed for recovery. The temporary 'sugar rush' is quickly followed by an energy crash, leaving you feeling worse than before. Instead, focusing on nutrient-dense, whole foods, and smarter, natural sweet alternatives will better support your body's healing process. So the next time a cold hits, opt for a soothing tea with honey or a fresh fruit smoothie instead of a box of cookies, and your immune system will thank you.

The Importance of Hydration and Rest

Beyond just food, remember that proper hydration and ample rest are crucial for a quick recovery. Sipping on clear liquids like water, broth, or herbal tea throughout the day helps combat dehydration, especially if you have a fever. Rest gives your body the energy it needs to focus on fighting the infection without being overworked. A balanced approach to nutrition, hydration, and rest is the most effective strategy for getting back on your feet.

The Gut Connection

Finally, the health of your gut microbiome is closely linked to your immune system. When you're sick, the balance of bacteria in your gut can be disrupted. Opting for fermented foods like yogurt or kefir, or a diet rich in fiber from fruits and vegetables, can help support a healthy gut environment, which, in turn, boosts your immune response.

Frequently Asked Questions

Your body craves sugar when you are sick for two main reasons: your immune system requires more energy to fight infection, and sugar triggers your brain's reward system, releasing dopamine and serotonin for a temporary mood boost and sense of comfort.

While a cool, smooth treat like ice cream can soothe a sore throat, it is high in both sugar and fat, which can increase inflammation and suppress your immune system. A better option is a real fruit popsicle or blended fruit smoothie.

Yes, excessive consumption of refined sugar can potentially prolong your illness. It can hinder the function of white blood cells, which are critical for fighting infections, and contribute to inflammation that can worsen symptoms.

For a cold, better alternatives to candy include a spoonful of honey in tea to soothe a sore throat, fresh fruit for vitamins, or ginger candy if you have nausea. These options offer some benefit without the negative side effects of high sugar intake.

When you have the flu, you should avoid sugary foods, fried and greasy foods, alcohol, and excessive caffeine. These can increase inflammation, dehydrate you, and put unnecessary stress on your body.

Sucking on a sweet item like a lozenge or a fruit popsicle can provide temporary relief for a sore throat by moistening the area. However, high-sugar candy will not help with healing and can increase inflammation.

The initial 'sugar rush' is quickly followed by an energy crash. This rapid spike and drop in blood sugar can leave you feeling more tired and less alert, which is especially problematic when your body is already compromised by illness.
