The Magnesium-Calcium Ratio Hypothesis






According to some, milk causes osteoporosis because it is high in calcium and low in magnesium.


Mother’s milk however, has the same magnesium-calcium ratio (1:10) as cow’s milk:


                                        Cow’s milk    Human milk

Calcium, average               120                   32

Calcium, variation         107 – 133        25 – 41       

Magnesium, av.                    12                      3

Magnesium, var.                 9 – 16             3 – 5         


And mother’s milk appears to perfectly enable the infant to grow strong bones, like cow’s milk does in calves.


Mother’s milk certainly does not enhance osteoporosis in suckling. On the contrary; mother’s milk enables infants to grow stronger bones very rapidly.


A study even showed an association between a high magnesium intake and hip fracture risk. (1)





Some say that magnesium and calcium are two competing minerals which naturally occur in a 1 : 2 balance. The more calcium is consumed the more magnesium is required. (to deport calcium from cells).


This of course is utter nonsense, there is no natural magnesium-calcium balance; this ratio is different per food.

And again, mother’s milk contains the least magnesium relative to calcium, and no sane person can claim that mother’s milk causes osteoporosis. (or that pork is preventive, and vegetables and oranges enhance osteoporosis)



The amount of magnesium relative to the amount of calcium in different foods:

Only 50% is natural?


844%           pork

800%           maize

683%           rice

414%           banana

391%           beef

334%           wheat

328%           potato

308%           chicken

250%           mackerel

223%           salmon

161%           oats

158%           mutton

123%           veal

44%           carrots

33%           orange

23%           broccoli

21%           chicken egg

10%           Cows milk (min. 3.5% fat)

10%           Human milk
