Cooling the Body Naturally: Chinese Nutritional Therapy for Summer Heat

The word diet originates from the Greek word diaita, meaning lifestyle, regimen, or a way of life. The earliest descriptions of Chinese dietitians can be traced back to the Zhou Dynasty (1100–700 BC), where nutrition was already rooted in principles of balance and harmony. At that time, the role of the dietitian focused primarily on the prevention of disease, along with the therapeutic use of food for both acute and chronic conditions. Prevention remains one of the foundational principles of Traditional Chinese Medicine (TCM).

As the renowned physician Sun Si Miao stated, “Without the knowledge of proper diet, it is hardly possible to enjoy good health,” and “Dietary therapy should be the first step when one treats a disease. Only when this is unsuccessful should one try medicines.”

I still remember how fascinated I was in acupuncture school when I learned that, historically, a physician’s salary was determined by the number of healthy patients they maintained, not by how many sick patients they treated annually. It’s a model of care I wish could inspire healthcare systems around the world today. It makes sense to me that healthcare should be rooted in the cultivation of health as a foundation rather than the management of disease. Such an approach invites both practitioners and patients to take a more proactive, preventative role in well-being, shifting the focus from symptom management to thriving and vitality.

According to TCM, there are five seasons to consider: winter, spring, summer, late summer, and fall. Late summer represents the final, often hottest, phase of the season. Here in St. George, summer seems to arrive early—sometimes as soon as March—and can extend through October, creating a long period of intense heat. The good news is that nutritional therapy offers some of the most effective and accessible tools to both prevent and address imbalances in the body and mind. The concept is simple: choose foods and drinks that naturally cool and hydrate you.

You have probably noticed how summer heat affects you, both physically and emotionally. When overheated, you may feel sluggish, tired, irritable, or restless. You might experience headaches, dryness, excessive thirst, sweating, disrupted sleep, skin eruptions such as rashes or acne, or changes in digestion. These are all ways your body communicates that it needs additional support. Chinese nutritional therapy focuses on keeping the body cool, hydrated, and calm during the summer months.

Simple seasonal guidelines include eating lighter meals and choosing fresh, local, seasonal foods, such as those found at your local farmers market. Focus on foods that hydrate and cool the body. Opt for preparation methods such as raw foods, steaming, or light sautéing rather than frying or slow cooking. Summer is also the only time of year when iced drinks are generally encouraged in TCM. They are typically avoided during colder months, though moderation is still important, as excessive cold can weaken digestion. It is best to limit heavy, greasy, and spicy foods, as well as alcohol, and to avoid drinking iced beverages first thing in the morning.

One of the main differences between Western nutrition and TCM nutritional theory lies in how foods are categorized. In Western nutrition, foods are often described in terms of proteins, carbohydrates, fats, vitamins, and minerals. In TCM, however, every food has an energetic nature. Foods are classified by their thermal properties (hot, warm, neutral, cool, or cold), flavor (sweet, acrid, sour, bitter, or salty), the organs they influence (such as the spleen, stomach, lungs, liver, large and small intestines, bladder, heart, or kidneys), and the direction of their energy (upward, downward, inward, or outward).

For example, blueberries are considered cool to neutral in nature, with a sweet and slightly sour flavor. They are said to support the kidneys, liver, and spleen and have a gently inward-moving quality. These characteristics make foods not only nourishing but also therapeutic tools that can help prevent or address imbalances. During the hottest months, cooling foods and lighter preparation methods are ideal, while warming foods are more appropriate during colder seasons. In this way, balance can be achieved. One of the greatest strengths of Chinese nutritional therapy is its flexibility. It adapts to each individual and supports the whole person rather than just isolated symptoms.

As you may already know, some of the best cooling fruits include watermelon, strawberries, blueberries, pears, pineapple, cucumber, and melon. They are light, juicy, and refreshing. Cooling vegetables include zucchini, summer squash, leafy greens, sprouts (especially alfalfa and mung bean sprouts), celery, and bitter melon. Although I have not seen bitter melon in a standard grocery store, it is often available at Asian Market, located at 1480 S. River Road. Beneficial summer drinks include mint tea, chrysanthemum tea, water infused with lemon and cucumber, and lighter caffeinated teas such as green, white, and light oolong teas.

Great protein sources during hot weather include light fish, tofu, lentils, mung beans, and grains such as rice or quinoa. Foods to limit during peak summer heat include spicy, greasy, and deep-fried dishes, processed sugar, alcohol, and excessive red meat. Try to avoid overly complex meals and heavy spices. Instead, enjoy the natural abundance of fruits and vegetables available this season. Use less salt, incorporate more water into cooking, and keep meals simple and light to avoid feelings of sluggishness.

When you begin to eat in harmony with the seasons, nourishment becomes more than just food; it becomes a daily practice of awareness and care. By understanding your body and choosing foods that support its needs, you create a deeper sense of balance, clarity, and connection. In this way, seasonal eating is not only a path to better health, balance, and longevity but also a way to live more intentionally and in rhythm with the natural world around you.
