The Black Hawk Institute* presents Report # 364 - Food Nutrient Changes
1963 to 1989. This report covers three common foods, eggs, peas and
tomatoes, and records the values reported in the USDA Report "Composition
of Foods" from 1963 and 1989. The figures given are for 100 grams of the
raw food listed.
If one assumes that a decline is soil fertility is expressed in the first
order as a decline in the Nitrogen, Potassium and Phorphous levels in the
soils, then this deficiency should also show up in the foods grown in these
depleted soils. For these three foods, the Protein content (N x 6.25) has
declined 13% according to the USDA number. The Potassium content is over
12% lower and the Phosphorus is 10% lower. These results are consistent
with decreasing levels of these nutrients levels in the soil. Another
interesting observation is that the sodium content of these foods is up by
over 117%, the iron content is down by 23% and the calcium content is down
by over 24% during this same time period.
The data for these three food is listed below for your analysis. Mike Miller
