The COVID-19 pandemic seems to have made people more health conscious in other ways too, such as diet.
People are cooking more at home, which is a good way to control salt intake, for instance.
Park Se-young has more.
This woman in her 30s tries to make her food not too spicy or salty when she cooks at home because she's grown tired of delivery food and is also concerned for her health.
When she wants to add some flavor, she tries to only use natural seasoning.
According to the food industry, sales of health-conscious products have increased greatly during the COVID-19 outbreak.
An online grocery delivery service saw its sales of low salt or salt-free products nearly double in the first nine months of this year compared to the previous year.
The most popular items were butter, nuts and chicken breast products with reduced or no salt.
To meet the demand, manufacturers have released low salt canned ham and fish cake.
"We eat more home-cooked meals because of COVID-19, so I'm trying to reduce my family's sodium intake."
Juice, snacks and even bread with reduced sugar are also popular.
A convenience store chain's sales of low sugar or sugar-free reconstituted milk products and soft drinks rose by around 50 percent on-year in the first six months of this year.
New food products support good health while still tasting great, and the demand for such products is only expected to rise.
