3 Common Foods That Lose Their Flavor - and May Even Produce Carcinogens - When Stored in the Refrigerator

Is the refrigerator really a "safe haven" for preserving food? Not always. Not all types of food are suitable for refrigeration. Dr. Yang Jingduan, a professor at the Center for Integrative Medicine at the University of Arizona (USA), warns that refrigerating certain ingredients not only strips them of nutrients and flavor but may also pose health risks.

He advises against storing the following three common foods in the refrigerator:

1. Potatoes

Storing potatoes in the refrigerator causes the starch to break down into sugar at low temperatures. When these sugars are cooked at high heat, they can produce a carcinogen called acrylamide.

The proper method is to keep potatoes in a dry, cool place away from direct sunlight. If you notice potatoes sprouting or turning green, even slightly, discard them. At this stage, their glycoalkaloid levels increase, which can lead to poisoning.

2. Honey

Many people mistakenly believe that honey should be stored in the refrigerator, but this is a common misconception.

Honey has natural antibacterial properties, but refrigeration causes it to crystallize, affecting its flavor. The correct method is to store honey in an airtight container at room temperature.

If honey has crystallized, don't worry. Simply place the jar in warm water (around 40°C) to melt it back to its liquid form easily.

3. Tropical Fruits

Some tropical fruits, such as bananas, mangoes, and pineapples, are highly sensitive to low temperatures. Refrigeration can cause the flesh to turn black and diminish their natural sweetness and aroma.

These fruits are best stored at room temperature, especially when they are unripe. Once cooked or processed, they can be refrigerated for a short time to extend their shelf life.
