All about fruitarianism with a long-term fruitarian, Lena

For many fruits, organic farming was nearly as productive as conventional farming (an average difference of just 3%). Cereals and veggies are where organic farming got trashed, with yields averaging 26 and 33% lower than conventional agriculture.

So the data suggests that switching to organic farming for specific crops like various fruits might be a smart move; the slight loss in productivity would be a small price to pay for the environmental benefit. Yet for other crops like corn, wheat and soybeans, organic farming would cut yields substantially. You could argue we grow more corn than we need, of course, because a lot of our corn goes to ethanol (thanks, Congress) and cattle (which is a crazy-inefficient use of corn, BTW — the ratio of corn consumed to beef produced is terrible). But the fact remains that organic farming is not the universal solution its advocates claim it to be. It looks like a good solution for a variety of specific crops, but we probably can’t do all our farming organically, because for many other crops it just doesn’t have anywhere near equivalent productivity.

Recommended Dietary Allowance RDA

Recommended Dietary Allowance (RDA) - the average daily dietary nutrient intake level sufficient to meet the nutrient requirement of nearly all - ~97% - healthy individuals in a particular life stage and gender group. 

The process for setting the RDA depends on being able to set an Estimated Average Requirement (EAR). If an EAR cannot be set, no RDA will be set. The EAR is the daily intake value of a nutrient that is estimated to meet the nutrient requirement of half the healthy individuals in a life stage and gender group.

The RDA is set at the EAR plus twice the standard deviation (SD) if known (RDA = EAR + 2 SD). If data about variability in requirements are insufficient to calculate a standard deviation, a coefficient of variation for the EAR of 10% is ordinarily assumed (RDA = 1.2 x EAR).

The RDA for a nutrient is a value to be used as a goal for dietary intake by healthy individuals. The RDA is not intended to be used to assess the diets of either individuals or groups or to plan diets for groups.
