Further, a PUFA rich diet also caused significant increase in peptide YY (PYY) -- a hormone that increases fullness or satiety. "These findings tell us that eating foods rich in PUFAs, like those found in walnuts, may favourably change appetite hormones so that we can feel fuller for longer," Cooper added. The PUFA-rich diet included whole foods such as walnuts, Alaska salmon, tuna, flaxseed oil, grape-seed oil, canola oil, and fish oil supplements. The control diet was comprised of 7 per cent polyunsaturated fat, 15 per cent monounsaturated fat and 13 per cent saturated fat, compared to the PUFA-rich diet which was 21 per cent polyunsaturated fat, 9 per cent monounsaturated fat, and 5 per cent saturated fat. These types of hormone changes imply better appetite control, the researchers said.
