A warning from experts has emerged that the common health advice of 'drinking 2 liters of water a day' could actually harm health. In the entertainment program tvN 'You Quiz on the Block', Honorary Professor Lee Gye-ho from Chungnam National University appeared and strongly pointed out the dangers of what is known as 'excessive water intake'.
On the 6th, in the 305th episode of 'You Quiz', Professor Lee Gye-ho, who has tracked harmful substances in food for 25 years, made an appearance as a guest. He is an expert who has researched everything from pesticides, heavy metals, and carcinogens to commercially farmed seafood and processed foods, and he provided a sharp analysis of 'poisons on the table' that day.
Professor Lee noted, "The slogan that the American Cancer Society has been shouting for over 30 years is 'Five A Day'; eating five different colored vegetables a day will prevent cancer," but emphasized, "What's even more important is water."
However, the statement that surprised everyone came next. When MC Yoo Jae-suk and Cho Sae-ho asked, "If you drink 2 liters of water a day, won't you live a long and healthy life?" Professor Lee responded with a twist, saying, "If you drink exactly 2 liters, your health will deteriorate."
He warned, "Some people even drink up to 4 liters thinking that the more water you drink, the better it is. There are cases where people eat too many vegetables and fruits thinking they are good, and also have extreme low-salt diets," and added, "People who do all three are going towards hyponatremia."
He even conveyed, "You could die suddenly at night due to a heart attack caused by hyponatremia," shocking both the MCs and the audience.
Professor Lee stressed, "Hydration does not come only from water. Watermelons and vegetables also contain a lot of moisture," and emphasized, "How much water one should drink in a day should depend on individual body weight, activity level, and food intake."
He continued, "If your urine color is a dark yellow in the bathroom, it is a signal that your body wants water," advising that it is important to develop the habit of 'checking your body's signals' rather than drinking water unconditionally.
In this way, Professor Lee Gye-ho cautioned that "some of the eating habits known to be good for health may be misconceptions," urging a cautious approach.
