BIO 111 Lecture Notes - Lecture 2: Dietary Reference Intake, Quackery, Dietitian
Document Summary
3 dietary guidelines we are going to review: You want foods with high nutrient and low calories. Nutrition quackery is a billion dollar/yr industry. No formal training and if so not credible. Need 4 yr undergrad degree plus 8-12 month internship. 3 methods are used to assess food intake: By usa and can for nutrient standards in both countries. Intake goals for given stage of life/gender. Goals when insufficient data is available for rda. Ranges of intakes for energy yielding nutrients that are sufficient to provide adequate total nrg and nutrients while reducing the risk of chronic diseases. Dris are designed for health maintenance and disease prevention in healthy people rather than preventing deficiency symptoms along. If this amount was recommended 50% of the population may develop a deficiency because they are not getting enough. The rda is therefore set at 2 standard deviations above the mean to ensure 97. 5% or population is met.
