Summer Cold Drinks & Metabolic Risks

During the hot summer season, many people enjoy iced drinks to cool down and relieve thirst. However, behind these refreshing beverages may hide health risks that should not be ignored. For cancer patients and those in recovery, excessive sugary drinks may affect metabolism, immunity, and long-term health.

Sugary soft drinks, juices, bubble tea, and smoothies may bring temporary comfort, but their high sugar content can place a heavy burden on the body. Many cold drinks contain far more sugar than the recommended daily intake, sometimes up to 10–20 teaspoons per serving. Long-term overconsumption may lead to fatty liver, insulin resistance, and unstable blood sugar levels.

Too much sugar encourages fat accumulation in the liver, increasing the risk of fatty liver disease and other metabolic problems. Insulin resistance is also linked to diabetes, cardiovascular disease, and higher cancer risks. For people recovering from illness, reducing sugar intake is important to support immunity and recovery.

High-sugar drinks may also affect emotional balance and mental focus. Sudden blood sugar fluctuations can cause fatigue, anxiety, mood swings, and poor concentration. Maintaining a stable physical and mental condition is especially important during recovery.

During the hot summer season, how can we stay cool while avoiding the hidden dangers of excess sugar? Here are some healthier drink choices and simple homemade beverage ideas for a refreshing and healthier summer.

  • Lemon water or lime water with little or no sugar, combined with fresh fruit slices, can be both refreshing and healthy.
  • Fruit smoothies made with low-sugar fruits such as kiwi, blueberries, and strawberries, blended with coconut water, are delicious and nutritious.
  • Herbal or flower teas, such as mint tea or chamomile tea, can be chilled before drinking, giving a cooling effect without added sugar. Additionally, some health supplements, such as St. John’s Wort, can also increase the risk of photosensitivity reactions.

Drink more plain water or mineral water. Adding fresh fruits or mint leaves can naturally improve the flavor and make hydration more enjoyable.

Reducing sugar is a gradual process, but small changes can make a big difference over time.

Avoid frequently buying canned or bottled sugary beverages. Preparing drinks at home allows better control over sugar intake and supports healthier habits.

Start by slowly reducing the sugar content in drinks and adjusting your taste preferences naturally.

Read nutrition labels carefully and choose low-sugar or sugar-free products whenever possible.

Build healthier replacement habits by choosing fruits, tea, or homemade drinks instead of sugary beverages.

Maintain a balanced diet with fiber, protein, and healthy fats to help stabilize blood sugar and reduce sugar cravings.

Try different healthy drinks regularly to keep your diet enjoyable and avoid relying on sweetened beverages.


To stay truly refreshed during summer, the key is not just enjoying icy drinks, but also reducing sugar intake and maintaining healthy metabolism and overall body balance. In addition to developing healthy eating habits, proper nutritional supplementation is equally important. Umi No Shizuku Fucoidan Powder can be easily incorporated into your daily diet and prepared conveniently. It is a suitable nutritional supplement choice for summer wellness and daily health management, helping support overall well-being and maintain a healthy condition.
