What to Not Eat in Summer for Better Health and Hydration

4 min read

Over 75% of Americans are chronically dehydrated, and this risk significantly increases during the summer months. To stay properly hydrated and comfortable when temperatures rise, it is crucial to pay attention not only to what you drink but also to what you eat.

Quick Summary

Certain foods and beverages should be avoided during hot weather to prevent dehydration, digestive discomfort, and heat-related issues. Heavy, spicy, and overly sweet items put extra strain on the body, making it harder to regulate temperature and stay cool.

Key Points

  • Avoid Heavy Meals: Digestion of large, high-protein meals creates metabolic heat, making you feel sluggish in hot weather.

  • Skip Fried and Greasy Foods: High fat content in fried foods increases body temperature and can cause bloating and indigestion.

  • Limit Sugary Drinks: Excessive sugar can lead to dehydration as your body works to flush out excess sugar.

  • Moderate Caffeine and Alcohol: Both are diuretics that cause fluid loss and increase your risk of dehydration.

  • Use Caution with Spicy Foods: While sweating can be a cooling mechanism, excessive spice can lead to faster dehydration if fluids aren't replenished.

  • Choose Lighter Options: Embrace water-rich fruits, vegetables, and lean proteins for easier digestion and better hydration.

  • Replenish Electrolytes: Drink coconut water or water with a little salt to replace minerals lost through sweating.

Heavy, High-Protein Meals

In the summer, your body's digestive system slows down slightly to conserve energy and regulate body temperature. Consuming large, heavy meals, especially those rich in protein, can cause your body to generate more metabolic heat during digestion. This process, known as diet-induced thermogenesis, can leave you feeling sluggish, lethargic, and uncomfortably full in the heat. Think of a big, heavy barbecue brisket sandwich—while delicious, it requires a lot of energy to break down, which works against your body's natural cooling mechanisms.

Greasy and Fried Foods

Fried and greasy foods are notorious for being difficult to digest due to their high fat content. During the summer, indulging in these can exacerbate feelings of discomfort, bloating, and indigestion. Beyond the digestive issues, fried foods contribute to overall poor health by being high in calories and unhealthy fats. The high fat content can increase your body temperature, making you feel hotter and more prone to heat-related illnesses. The oils used for frying often contain trans fats and harmful compounds that are best avoided, particularly during a time when your body is already under added stress from the heat.

Sugary Drinks and Excessive Sugar

While a super-sized, sugary soda or fruit juice might seem refreshing, it can actually contribute to dehydration. High sugar levels in the bloodstream force the kidneys to produce more urine to flush out the excess, which leads to increased fluid loss. This can cause your body to lose electrolytes, which are vital for proper nerve and muscle function and maintaining hydration. A sugar crash can also leave you feeling more drained and fatigued than before you had the drink. Instead of reaching for a sugar-laden beverage, opt for hydrating alternatives like water infused with fruits or herbal iced teas.

Spicy Foods: A Double-Edged Sword

Spicy foods, particularly those containing capsaicin found in peppers, stimulate nerve receptors that make you feel hot, causing you to sweat. This sweating is your body's way of cooling down, and in some climates, this can be an effective and traditional way to manage heat. However, excessive sweating can also lead to faster dehydration, especially if you're not consistently replacing lost fluids. For many, the initial heat from spicy food is simply uncomfortable and may lead to digestive upset, which is undesirable on a hot day. While a moderate amount might be fine, overdoing it can be detrimental to your comfort.

Excess Caffeine and Alcohol

Both caffeine and alcohol are diuretics, meaning they increase your body's urine production and accelerate fluid loss. In hot weather, when you are already losing fluids through sweat, this diuretic effect can quickly lead to dehydration. Beyond dehydration, alcohol impairs your body's ability to regulate its own temperature, which increases your risk for heatstroke. Caffeine can also elevate your heart rate and body temperature, making you feel even hotter. Moderation is key, and it is always a good idea to alternate these drinks with a glass of water to help counteract their dehydrating effects.

A Comparison of Summer Food Choices

Feature Foods to Avoid Foods to Embrace
Digestion Effort High (heavy meats, fried items) Low (fruits, salads, light proteins)
Hydration Impact Dehydrating (alcohol, caffeine, sugar) Hydrating (watermelon, cucumber, smoothies)
Body Temperature Increases (spicy, heavy meals) Lowers (water-rich, cooling foods)
Nutritional Density Often low (processed, high-fat) High (fresh produce, lean meats)
Energy Levels Causes crashes and sluggishness Provides sustained, steady energy

The Problem with Excessive Ice Cream

While ice cream is a classic summer treat, excessive consumption isn't ideal. It provides a momentary cooling sensation, but the high fat and sugar content can be counterproductive. Similar to sugary drinks, the high sugar can dehydrate you, and the fat content makes it harder for your body to digest, increasing internal heat. A small serving is a fine indulgence, but it should not be a staple in your summer diet. Opt for healthier, cooling alternatives like homemade fruit popsicles, frozen yogurt, or a simple fruit salad.

Conclusion: Making Smarter Summer Choices

To beat the summer heat and maintain your well-being, the secret lies in mindful eating. By avoiding heavy, greasy, and overly sugary foods and drinks, you reduce the strain on your digestive system and help your body regulate its temperature more effectively. Prioritize light, hydrating foods such as water-rich fruits and vegetables, and drink plenty of water throughout the day. Moderating your intake of caffeine and alcohol will also play a significant role in preventing dehydration and enjoying a healthier, more energized summer.

Frequently Asked Questions

Heavy, high-protein meals can increase your body's metabolic heat as it works to digest them, which can make you feel more sluggish and uncomfortable in hot weather.

Spicy food initially makes you feel warmer and causes you to sweat, which is the body's cooling mechanism. However, if you don't adequately replace the fluids lost through sweat, it can lead to dehydration.

Yes, but in moderation. Coffee's caffeine is a diuretic and can lead to increased fluid loss. Limiting intake and drinking extra water is recommended to prevent dehydration.

Alcohol is a diuretic and impairs your body's ability to regulate temperature, significantly increasing your risk of dehydration and heat-related illnesses.

Healthier alternatives include homemade fruit popsicles, frozen yogurt, or a chilled fruit salad. These options provide a refreshing treat without the excessive sugar and fat of traditional ice cream.

You can add flavor to your water with natural ingredients. Try infusing water with fruits like lemon, cucumber, or berries, or brewing herbal iced teas.

Eating fried foods can cause digestive distress like bloating and indigestion. The high fat content makes your body work harder to digest, which can increase your body temperature and contribute to dehydration.
