Recently, while perusing the Dole Nutrition Institute Newsletter, I came across an interesting article about palmitic acid, a saturated fat found in meat and whole milk dairy foods, as well as in palm oil (which is used extensively as a preservative in shelf-stable processed foods).
According to research done at the University of Cincinnati, palmitic acid actually interferes with the metabolic process that controls appetite and thermogenesis (the conversion of calories to body heat).
Usually, when fat is ingested, there is a rise in blood leptin levels – which still occurs when the fat consumed is palmitic acid. However, the presence of palmitic acid reduces the normal brain response to leptin (the actual hormone that triggers satiety and thermogenesis) by roughly half…so even though the hormone is present, the brain ignores it!!
Basically, what this research suggests is that, when you eat a food containing high levels of palmitic acid (think: cookies, chips, pastries, ice cream, etc), you are at an even higher risk of over-consuming the food because your body, itself, doesn’t even realize when it’s had enough.
Take home message? Check the ingredient list and steering clear of anything containing palm oil (good luck!)…
Dole prefers you to stick to fruits and vegetables (which, by the way, not only fill you up physically, but also contain compounds that help support the right hormonal balance needed for hunger control) – imagine that!
