The study focused on a handful of the fat-soluble carotenoids, such as lycopene, lutein, and zeaxanthin. Lab studies show these compounds have antioxidant and anti-inflammatory properties. And AICR’s expert report and its updates show that eating foods containing carotenoids lowers the risk of mouth, pharynx, and lung cancers.
The study was published online in the journal Molecular Nutrition & Food Research.
In the study, 29 people ate salads topped with three dressings high in different fats: monounsaturated, polyunsaturated, and saturated.
