Most people believe that the refrigerator is the safest place to preserve any food. However, that habit, while it seems logical, may be slowly damaging your health. Some common foods react negatively to the cold, losing nutrients, altering their chemical composition and, in certain cases, favoring the formation of substances harmful to the body.

The most worrying thing is that these changes are not always noticeable to the naked eye. They don’t smell bad, they don’t taste different right away, but over time they can affect the digestive system, the brain, and the body’s inflammatory processes.

Below you will discover five foods that should never be kept in the fridge and why.

1. Potatoes

When potatoes are stored cold, their starch is converted into sugar. This change may seem harmless, but when cooked at high temperatures, that sugar is transformed into potentially harmful compounds.

In addition, refrigerated potatoes can cause blood glucose spikes, which affects energy and can aggravate metabolic problems. The cold also accelerates the appearance of green spots and breakouts, signs of natural toxic substances.

How to store them properly:
In a dark, dry, and ventilated place, such as a cupboard or pantry, away from sunlight.

2. Onions

The refrigerator is a humid environment, and the onion absorbs that moisture easily. This causes it to soften, deteriorate faster and promote the growth of invisible microorganisms.

In addition, the cold destroys some of your natural antioxidants, which are essential for fighting inflammation and protecting cells from aging.

How to store them correctly:
In a cool, dry place with good air circulation, such as a basket or a paper bag.

3. Tomatoes

The cold stops the natural processes that allow the tomato to retain its flavor and nutrients. The pulp becomes floury, loses firmness, and its antioxidants, especially those that protect the heart and brain, are reduced.

The cold tomato may look normal on the outside, but on the inside it has lost much of its nutritional value.

How to store them correctly:
At room temperature, away from direct sun, preferably with the stem facing upwards.

4. Garlic

When garlic is refrigerated, it begins to sprout and its composition changes. This reduces their protective properties and can generate substances that irritate the digestive system.
