Food Sources of Calcium
It is a widespread nutritional myth that dairy produce is a good source
of calcium. Milk products do contain a fair amount of calcium, particularly
hard cheese but, because of the calcium to magnesium ratio in these
products, the calcium is not well absorbed. As well as inhibiting
the body's ability to absorb magnesium, eating dairy foods in excess
can cause the body to produce too much mucous. As you can see in the
table of calcium rich foods below, seaweeds and other land plants
offer the best sources of bioavailable calcium.
Generally it is not that a person is not eating enough calcium - it
is one of the most widely occurring nutrients in our diet. It is more
the case that lifestyle choices and dietary habits might interfering
with the body's ability to absorb calcium. Things that inhibit the
absorption of calcium are
- Coffee, soft drinks and diuretics
- Excesses of protein, especially meat
- Refined sugar or too much of any concentrated sweetener or sweet
flavoured food
- Alcohol, cannabis, cigarettes and other intoxicants
- Too little or too much exercise
- Excess salt
- The Solanum (deadly nightshade) genus of vegetables - tomatoes
in particular, but also potatoes, aubergines, peppers, courgettes
- they all contain the calcium inhibitor solanine.
