What are Omega-7 fats and how do you know if you're getting enough? Nutrition Diva explains.
Q. I generally eat fish 5-7 times a week. After reading your article on whether it's possible to get too much omega-3, I have stopped taking fish oil supplements. Instead I'm taking an omega-7 supplement. What's your opinion of this product?
A. I think an omega-7 supplement is probably unnecessary.
Omega-7 fats are a sub-category of monounsaturated fats found in both plants and animals. You'll find relatively high concentrations in cow's milk and macadamia nuts as well as in the fruit of the sea buckthorn, a shrub that's not generally part of the (human) food supply. Your body can can also convert other fats into omega-7s. There's no recommended intake for this nutrient and no known risks associated with omega-7 deficiency. In other words, if your diet contains a reasonable variety of whole foods, you're probably getting (or making) all the omega-7 you need.
That said, researchers are investigating whether concentrated dosages of omega-7s might have unique therapeutic properties. Preliminary findings in lab rats suggest that it might help control appetite and/or lower cholesterol. But we're a long way from documenting such benefits in humans. For now, I don't think the research justifies spending money on a special supplement. Just because someone puts it in a bottle, doesn't mean we need it!
