The nutritional value of beets : Part 1- Beets, fresh, raw

Here is where I get up on my soapbox to begin a discussion of the nutritional value of beets: the good stuff, the bad stuff, the right stuff and the just plain wrong stuff that has been published and/or believed about beets. 


Beets: fresh, raw, velvety, and full of goodness


 A chart of the common factors that are measured in food laboratories is a useful tool at this juncture. I chose to use the United States Food and Drug Agency (FDA) Nutritional Nutrient database, a source which is easily accessed and to which common reference can be made.

From this data, we observe that beets are found to have nutritional values that are generous in folates, manganese and Vitamin C, and in carbohydrates and dietary fibre, as well as the phytonutrients Carotene-B and Betaine. In future posts, these factors and related subjects will be explored.

Another source, the IFAfitness.com book ( http://www.ifafitness.com/book/USDA-RDA.htm ), has been used for the percentage of Recommended Daily Allowances (RDA-RDI), for additional information.  It is as accurate as I could manage to find at this time.

Data in the IFA tables are categorised by age and gender. These data listed below are for adult females (generalised). For adult males (generalised ), the percentages of RDA (not listed here) are lower. The RDA for some elements is not available simply because either I haven't located a reliable source or there is no published general agreement upon what that allowance should be. For precise data, please visit the IFA site and check the entries for your gender and age.
