Fermented Foods — Food & Nutrition

What is Fermented Foods?

Foods that may positively affect skin health through the Gut-Skin Axis

Includes yogurt, kefir, kimchi, and fermented milk. Probiotics may improve gut microbiome, potentially helping sensitive skin and atopic conditions.

Characteristics & nutrition facts

Fermented foods such as yogurt, kefir, kimchi, and fermented milk contain beneficial microbes such as the lactic acid bacteria generated during fermentation. Research has been reported that these microbes act on the gut environment and, through the so-called 'gut-skin axis,' may have a positive influence on skin health. It is also known to be characteristic that fermentation changes the absorbability of some nutrients.

How to manage

Consistently eating a small amount daily is generally recommended for maintaining gut balance. Because kimchi and salted foods are on the high-sodium side, moderating the amount is recommended, and for sweetened yogurt it is best to choose products with little added sugar. Alternating among various types is a useful reference for microbial diversity.

Good to know alongside

Eating them together with dietary fiber (prebiotic) foods that feed beneficial microbes is a useful reference for a nutrition combination. In certain conditions such as immune suppression, caution with live-culture intake may be needed, so professional consultation is recommended.

Everyday care tips

Pairing unsweetened plain yogurt with fruit and nuts lets you enjoy it while reducing added sugar. The habit of adding a dish of kimchi to a meal helps you get fermented foods.
