Carbohydrate, Fat and Mortality
Reposted January 3, 2018 with an additional dietitian viewpoint*
The study, Associations of Fat and Carbohydrate Intake with Cardiovascular Disease and Mortality in 18 Countries from Five Continents (PURE): A Prospective Cohort Study, stemming from the PURE macronutrient studies, has been getting a lot of press across the globe (e.g. Canada, U.K.). This is a very large international cohort comprising high, middle and low income countries. It is an observational analysis with dietary intake collected by self-reported food frequency questionnaires (FFG) at baseline only. After looking at a range of carbohydrate (46-77% of energy) and saturated fat (2.8-13.2% of energy) intake (not a typical range seen in North America or Europe) the authors found that high carbohydrate intake was associated with a higher risk of total mortality, and non-cardiovascular disease mortality (e.g. cancer, respiratory diseases).

Should Dietary Reference Intake (DRI) Values be Developed for Lutein?
Lutein has been studied for its role in eye health and for preventing or delaying macular degeneration. Lutein is a carotenoid antioxidant found in high amounts in dark green, orange, red and yellow vegetables and fruits. According to the article by Ranard, et al., Dietary
guidance for lutein: consideration for intake recommendations is scientifically
supported, there is enough evidence to establish DRIs for lutein. This is based on lutein meeting nine criteria as described by Lupton, et al. The criteria help to determine if dietary recommendations should be established for bioactive substances such as lutein, lycopene, isoflavones, etc. For more information on eye health, including lutein, see the Eye Health Knowledge Pathway.
Additionally, the National Academies
of Sciences, Engineering and Medicine has recently published a consensus
report that outlines principles for developing Dietary Reference Intakes for nutrients and other food substances that incorporate chronic disease considerations.
