In Question Is Just Why Was This Guideline Given?
All it takes is rolling back time to the beginning of the last century or even going back several decades to the second world war when our food nutrition levels really began to degrade. Chemical fertilizers were being widely used throughout the country as the growth of this industry showed great promise to bring in more profit. Of course the big agricultural farmers were the one's that would reap the greatest profits. The consumers would lose since crops would suffer the loss of many needed nutrients because chemicals cannot return needed nutrients to the soil. In the 1950's the U.S. introduced irradiation in an attempt to kill bacteria in our foods at the processing plants before being shipped to the consumer. It is now known that this process of irradiating foods also depletes some of the nutrients in the process now becoming a double whammy in the nutrients per pound of food harvest. Simple arithmetic tells us that when at an earlier time we needed to eat less to supply our perfect engine with the required nutrients to run properly we now need to eat more. What this does of course is to increase big Agra profits. The consumer just has to spend more to remain at par and by eating more to sustain proper nutrition which simply leads to obesity.
Some of my findings on magnesium alone which controls over 300 human bodily functions has been greatly affected by some of the historic progress in our agricultural changes. Excerpts were gathered from the source of this Information which was derived from the link below:

Here are some of these excerpts:
Widespread Dietary Deficiency
A 1994 Gallup poll found that 72 percent of Americans don't consume sufficient amounts of magnesium. The widespread consumption of processed foods has led to a progressive decline in dietary magnesium. While nuts and green leafy vegetables are good sources of magnesium, the shortage of magnesium in the American diet, about 200-300 milligrams per day, is not likely to be made up through foods alone.
Progressive decline of dietary magnesium consumption
Years Magnesium intake milligrams per day
1900-08 475-500
1909-13 415-435
1925-29 385-398
1935-39 360-375
1947-49 358-370
1957-59 340-360
1965-76 300-340
1978-85 225-318
1990-2002 175-225

With this compiled data regarding this single and one of the most important minerals we should probably give some thought about supplementing our diets with magnesium. Given this information it might even be wise to also visit link below which gives a greater depth in the study of both magnesium along with vitamin D.
