Is it bad to eat sweets when you have a sore throat? The sweet truth explained

6 min read

According to a study published in the American Journal of Clinical Nutrition, high sugar intake can weaken the body's immune response, making it harder to fight off infections. So, is it bad to eat sweets when you have a sore throat? The answer isn't so simple, but generally, it's best to limit your intake to avoid prolonging your discomfort.

Quick Summary

Excess sugar can increase inflammation and suppress the immune system, potentially worsening a sore throat caused by an infection. While cold treats like ice cream may offer temporary relief, alternatives exist. Consider low-sugar options and focus on immune-boosting foods to support healing.

Key Points

  • Inflammation: High sugar intake increases inflammatory markers in the body, which can worsen throat pain and swelling.

  • Immunity: Consuming too much sugar can temporarily suppress the immune system, making it harder for your body to fight the underlying infection.

  • Bacteria: Excess sugar in your system can feed bacteria, potentially allowing the infection to linger and making symptoms last longer.

  • Dairy Concerns: For some, dairy in sweets like ice cream can thicken mucus and increase throat irritation.

  • Best Alternatives: Opt for low-sugar, non-acidic, soft foods like smoothies, plain yogurt, and warm broths to soothe and nourish your throat.

  • Honey for Soothing: Honey is a natural antimicrobial and anti-inflammatory that can coat and soothe the throat. Do not give to children under 1 year old.

  • Hard Candy Exception: Sucking on a hard, sugar-free candy can promote saliva and moisten the throat for temporary relief, but should be used in moderation.

The Double-Edged Sword of Sugary Treats

For many, a craving for comfort food hits when they feel under the weather. And what's more comforting than a sugary treat? For a sore throat, the answer is complicated. While the cold temperature of ice cream or a popsicle might feel soothing initially, the high sugar content can do more harm than good in the long run. Understanding why requires a closer look at how sugar interacts with your body's healing process.

How Sugar Hinders Recovery

Excessive sugar, particularly refined sugar found in sweets and baked goods, can negatively impact your immune system and overall health. Here are the key ways sugar can worsen a sore throat:

  • Promotes Inflammation: Refined sugar triggers inflammatory markers in the body, such as cytokines, that can exacerbate existing inflammation. For an already inflamed throat, this means more pain and swelling.
  • Weakens the Immune Response: High sugar intake has been shown to reduce the effectiveness of white blood cells, which are crucial for fighting off the virus or bacteria causing your sore throat. By consuming too many sweets, you are essentially hindering your body's ability to heal itself effectively.
  • Feeds Bacteria: Some research suggests that bacteria can feed on excess sugar in your system, potentially allowing the infection in your throat to thrive. This can make it take longer for your symptoms to subside.
  • Dehydration: Sugary sodas and fruit juices can be dehydrating due to their high sugar content. Staying hydrated is vital for a sore throat, as it helps keep the throat moist and thins out mucus. Choosing water over sugary drinks is a much better option.

Soothing Sweets vs. Aggravating Treats: A Comparison

It's not all bad news. Some sweet options can be part of a sore throat recovery plan, but it's important to choose wisely. Here is a comparison of different sweet items and their effect on a sore throat.

Item Potential Benefits Potential Downsides Best for Sore Throat?
Traditional Sweets (e.g., hard candy, lozenges) Hard candies can stimulate saliva production, which keeps the throat moist and soothed. Many contain high sugar, which can increase inflammation and inhibit the immune system. Use with caution, opt for sugar-free if possible.
Ice Cream The cold temperature can temporarily numb the throat and reduce swelling. High sugar and fat content can increase inflammation. Dairy can also thicken mucus for some people. Limited use only, choose low-sugar and non-dairy options if available.
Honey Natural antimicrobial and anti-inflammatory properties. Coats the throat to reduce coughing and irritation. High sugar content, though typically less refined. Avoid for infants under 1 year due to botulism risk. Yes, in moderation. Add to tea or warm water for best effect.
Popsicles (made with fruit juice) The cold helps numb the throat and provides hydration. Many are high in added sugar. Acidic fruit juices can irritate the throat. Choose all-fruit, non-acidic sorbets or make your own with non-acidic fruits like bananas or berries.

Beyond Sugar: What to Eat for Relief

Instead of reaching for high-sugar sweets, focus on nourishing foods that can actively aid your recovery. The following are excellent choices for a sore throat:

  • Warm Broths and Soups: They are hydrating, easy to swallow, and some, like chicken soup, even offer mild anti-inflammatory benefits.
  • Herbal Teas: Warm (not hot) tea can be very soothing. Chamomile, ginger, and peppermint teas have additional anti-inflammatory properties. Add a little honey for extra relief, if desired.
  • Soft, Creamy Foods: Mashed potatoes, scrambled eggs, cooked cereals like oatmeal, and yogurt (plain, low-sugar) are gentle on the throat and provide necessary nutrients.
  • Smoothies: Pack a smoothie with non-acidic fruits like bananas, berries, and spinach for a nutrient-dense, easy-to-swallow meal replacement.
  • Ice Cubes or Shaved Ice: Sucking on ice is a simple, effective way to numb the throat without the high sugar and fat of ice cream.

Conclusion: Prioritize Healing, Not Indulgence

While a sweet treat can provide momentary comfort, the evidence suggests that eating sweets when you have a sore throat can potentially prolong the illness and increase inflammation. The high sugar content may inhibit your immune system, making it harder for your body to fight off the underlying infection. The initial relief from a cold item like ice cream is often short-lived and doesn't outweigh the negative effects of the sugar. The best approach is to limit sweets and instead focus on nourishing, gentle foods and drinks. Prioritizing rest and hydration, along with opting for immune-boosting foods and natural remedies like honey and warm teas, is a far more effective strategy for getting back on your feet quickly. The occasional sugar-free lozenge may be fine, but a box of cookies is best saved for when you are fully recovered.

The Role of Inflammation and Immune Suppression

One of the main reasons sugary foods are detrimental to sore throat recovery is their direct link to inflammation. When you ingest a large amount of sugar, it can trigger a response in your body that releases inflammatory markers. For a sore throat, which is already an inflammatory condition, this can intensify the pain and swelling. Furthermore, high blood sugar levels can temporarily reduce the ability of white blood cells to destroy bacteria and viruses. This compromises your body's natural defenses, allowing the infection to persist longer. The combination of increased inflammation and a weakened immune system creates a less-than-ideal environment for healing.

What to Consider with Dairy and Sugar

Some sugary treats, like ice cream, also contain dairy. For some individuals, dairy can cause mucus to thicken, which can further irritate an already sore throat. This can worsen symptoms like postnasal drip and congestion. If you notice a correlation between dairy intake and increased phlegm, it's wise to avoid dairy-based sweets altogether. Alternatives like fruit-based sorbets or non-dairy ice creams might offer the cooling relief you seek without the potential for mucus buildup. However, always be mindful of the added sugar content in these alternatives as well.

Staying Hydrated is Key

Dehydration is a common side effect of many illnesses, and it can significantly worsen a sore throat. Sugary drinks, including sodas and many packaged juices, are not effective for rehydration and can actually have a diuretic effect. Focusing on water, herbal teas, and broths is the best way to ensure your throat stays moist. A moist throat is less likely to become irritated, and proper hydration supports your body's overall healing functions. While a cold, sugary soda might feel good on the first sip, it will not help your recovery in the long run.

Smart Choices for Symptom Relief

Instead of relying on processed sweets for comfort, look to more beneficial options. A warm (not hot) cup of tea with a spoonful of honey can provide immediate soothing relief. Popsicles made from non-acidic fruits like melon or banana can offer a refreshing, numbing effect with less sugar. Even a simple bowl of warm, blended soup can provide the comfort and nutrients you need without the drawbacks of refined sugar. Prioritizing these smart, gentle choices will help you recover faster and feel better sooner.

When is a Little Sweetness Okay?

While it's generally best to limit sugar, there are some exceptions. Sucking on a hard candy or throat lozenge can provide temporary relief by moistening the throat. The National Health Service (NHS) in the UK even suggests sucking on hard sweets for a sore throat, but warns against giving them to young children due to choking hazards. The key is moderation and choosing options with minimal added sugars, or even sugar-free varieties, to avoid the negative systemic effects of sugar on your immune system. Remember that this is for temporary symptom relief, not as a recovery strategy.
