Sweet, sour, bitter, salty, umami, and.... fat? Dr. Russell Keast
, an Austrailian scientist who studies
"perceived flavour, consumer acceptance and preference of foods and nutrition," has conducted research exploring humans' apparent sixth taste perception: fat. The kicker? Sensitivity to the taste of fat was negatively correlated with fat intake and BMI. Dr. Keast discussed the results of his latest research
, and The Sydney Morning Herald
Some notable excerpts of Dr. Keast's statements about the latest research:
"We have sweet to identify carbohydrate/sugars, and umami to identify protein/amino acids, so we could expect a taste to identify the other macronutrient: fat."
''Fat has a very nice mouth feel to it [but it] appears that fat is activating something in the oral cavity independent of texture.''
And from the abstract:
[to oral fatty acids] was associated with lower energy and fat intakes, lower BMI and an increased ability to rank custards based on fat content.
...oral fatty acid hypersensitivity is associated with lower energy and fat intakes and BMI, and it may serve as a factor that influences fat consumption in human subjects.
And here's a PDF summary of Dr. Keast's earlier fat-taste research.
