  • Canola
  • The US National Heart, Lung and Blood Institute urged saturated fats be replaced with polyunsaturated and monounsaturated fats, listing olive and canola oils as sources of healthier monounsaturated oils while soybean and sunflower oils as good sources of polyunsaturated fats. (wikipedia.org)
  • hypothesis
  • The hypothesis that saturated fat has a detrimental effect on human health gained prominence in the 1950s as a result of the work of Ancel Keys , a US nutritional scientist . (wikipedia.org)
  • mortality
  • 3 Furthermore, no association existed between dietary fat and mortality from all causes of death. (bmj.com)
  • Available evidence from adequately controlled randomised controlled trials suggest replacing SFA with mostly n-6 PUFA is unlikely to reduce CHD events, CHD mortality or total mortality. (wikipedia.org)
  • meta-analyses
  • Other meta-analyses based on cohort studies and on controlled, randomized trials found a positive, or neutral, effect from consuming polyunsaturated fats instead of saturated fats (a 10% lower risk for 5% replacement). (wikipedia.org)
  • oils
  • Drying oils, which polymerize on exposure to oxygen to form solid films, are polyunsaturated fats. (wikipedia.org)
  • Fats and oils are categorized according to the number and bonding of the carbon atoms in the aliphatic chain. (wikipedia.org)
  • To make vegetable shortening, then, liquid cis-unsaturated fats such as vegetable oils are hydrogenated to produce saturated fats, which have more desirable physical properties e.g., they melt at a desirable temperature (30-40 °C), and store well, whereas polyunsaturated oils go rancid when they react with oxygen in the air. (wikipedia.org)
  • Mayo Clinic has highlighted certain oils that are high in saturated fats, including coconut, palm oil and palm kernel oil. (wikipedia.org)
  • Clinical
  • Results from observational clinical trials on polyunsaturated fat intake and cancer have been inconsistent and vary by numerous factors of cancer incidence, including gender and genetic risk. (wikipedia.org)
  • Olive oil contains monounsaturated fats, most notably oleic acid, which is under clinical research for its potential health benefits. (wikipedia.org)
  • total calories
  • The vilification of saturated fat by Keys 2 began two decades before the seven countries study, where Keys showed a curvilinear association between fat calories as a percentage of total calories and death from degenerative heart disease from six countries. (bmj.com)
