In October last year, a research group at Japan's Kyushu University discovered the neurons that are key to the brain's perception of the taste of fat. This supports the notion of fat as the sixth sense of taste following sweet, salty, sour, bitter, and umami. If you are insensitive to the taste of fat, you are susceptible to lifestyle-related illnesses. In this edition of the program, we conduct a fat sensitivity taste test across age groups to see the relationship between tasting ability and health.
