Chances are you are taking a calcium supplement because are health-conscious?
But do you really need it – or are you even harming yourself with your calcium pill?
It is true that bones need calcium for growth. What is not true is that calcium alone gives us stronger bones. Bones need far more than just calcium: Other minerals like potassium, magnesium, manganese, phosphorus, chromium, sulfur, selenium, boron – and others – are necessary for bone health. Without these other minerals, calcium alone is pretty useless.
Besides, calcium pills – those fat bummers that are hard to swallow because of their size – are also hard to digest. As a physician, I have seen my share of undigested calcium pills popping up on x-rays, somewhere lying in the bowels, useless.
That milk is an unsuitable source of calcium, you have heard here before. Besides being an unhealthy food, the calcium from milk is also not as readily available as the calcium from vegetables, fruit, legumes, whole grains and nuts. The plant world is so abundant in calcium that adding vitamin D to milk as a selling argument comes close to a joke: Dairy is a cause for obesity, heart disease, diabetes, cancer, and so on.
For good bones you need a host of minerals – all conveniently available in plant foods – plus sun and exercise. Not so much sun, actually, as light. Even on an overcast day, a midday outdoors walk will trigger the necessary amount of vitamin D production beneath your skin. Inner-city people with dark skin are mostly at risk of osteoporosis because they need more sun exposure.
And if you don’t move, you will lose your bone strength fast. A little known fact: We are losing some bone every night, from being inactive during sleep. An active person will rebuild that loss (and more) the next day. An inactive person won’t.
A study in the British Medical Journal recently found that calcium supplement could increase the risk of a heart attack by thirty percent. Clearly, we have to rethink health: Health does not come from pills. It comes from a lifestyle that uses our body for which it is intended: joyful activity, fresh foods, sufficient sleep. And hugging and kissing, if you ask me. Read More

Seasonal Indulgences
June 4, 2010
White asparagus, new potatoes, chopped parsley in melted butter and prosciutto - have you ever tasted the joy of this? I did last week - traveling in Europe. This is asparagus time, and it is eaten plentifully. Followed by strawberries.
In years gone, I have tried asparagus with sauce Béarnaise or sauce Hollandaise, with Wiener Schnitzel or salted herring. I had it as soup or stew. This year, I learned a new asparagus dish: Jam – made with sweet woodruff (Galium odoratum), an herb that should only be harvested in May, with a flavor that is indescribably delicious – pure May indeed.
But my point is not the asparagus or the sweet woodruff; the point is that Europeans eat in season. They fantasize all year about asparagus with “young” potatoes – and when the white spears finally shoot out of the soil, there eat them often. Until mid-June (the exact date varies from north to south), when traditionally the last white asparagus is cut to let the plant develop strength for next year. After mid-June … nothing for a whole year.
Medicinally, asparagus flushes the kidney and moves the bowel (fiber!), taking with it toxins that have accumulated over the long winter. Parsley gives vitamin C, depleted after the cold season. And young potatoes round out the composition that delights the taste buds. In medieval times it was thought to be an aphrodisiac – but anything that was growing freshly after the long winter and had a phallic form might have served for the purpose, I guess.
Asparagus contains vitamins A, C, B1, B2, and E and is thought to help regeneration of cells, especially of nerves, vessels, skin and hair. White asparagus is kept white by growing them in deep soil, and they always need peeling of the tough skin (which might be the reason that green asparagus is preferred here – less work). Asparagus is rich in calcium, magnesium, iron, zinc, phosphorus, potassium and copper – all minerals sorely needed for bone strength.
Of course, it is possible to get white asparagus year-round. But Europeans still stick to the ancient clock: Over there, they have a time for everything, and May/June is dedicated to asparagus and strawberries.
We here think nothing of eating the good stuff whenever we feel like it. We don’t think about that the good stuff is made expensive by world-wide travel, and leaves a huge carbon print. Not to mention of the health consequences. Eating the same thing over and over again makes one prone to food allergies, for instance. And the old wisdom of the body is that what is in season is right for the body when it is in season. Not by chance but because we developed over millions of years together with the plants.
Here a small sample of what should be eaten when – and it is not only ancient lore but modern chrono-biology confirms the value of eating in season:
• January: red Beat
• February: celery, celeriac
• March: spinach, stinging nettle
• April: radish, rhubarb
• May: lettuce
• June: cucumber
• July: carrots, black currants, gooseberries, raspberries
• August: tomato, first apples, blueberries, raspberries.
• September: broccoli, cauliflower
• October: leeks
• November: cabbage
• December: rapunzel
(I will add to these!)
We delight in Christmas, and sometimes go over the top with Christmas decorations and gifts and events. Perhaps, if one had something to look forward year-round, would Christmas take its place among many seasonal delights? Read More
Dairy II: Bone Health
May 25, 2010
Bones contain calcium, potassium, manganese, magnesium, silica, iron, zinc, selenium, boron, phosphorus, sulfur, chromium, and more – but the dairy industry tries to tell us all we need for strong bones is calcium?
Cows eat nothing but grass – and we can’t compare with their bone strength (granted, they have different stomachs than we have – but I also haven’t asked you to eat grass…).
Vegetables contain enough calcium for strong bones. Plus they contain all the other minerals healthy bones require. We don’t need fortified, adulterated, hormone-injected dairy products for our bones. Also, the daily requirements for calcium seem to be put artificially high: In one study in Africa, women took in about only half the recommended dose and maintained excellent bone health.
Nuts are also full with all the different minerals we need. The problem with nuts of course, are allergies and reactions to lectins. So, if nuts don’t agree with you, don’t push them! And beware of rancid/roasted nuts! Their bad fats do more harm than good whereas fresh nuts contain beneficial omega-3’s.
Another problem with dairy is that it provides protein – and the Standard American Diet (SAD) contains too much protein as it is. We are omnivores by nature – once in a while a piece of meat (not deli!) between our teeth provides us with essential nutrients like vitamin B12 that are hard to come by otherwise – just not every day. But too much protein leaches out calcium from the bone – at least that is one theory. It says that the metabolic products of protein digestion are acidic, and need alkaline buffering for buffering, and so calcium is leached out of the bones. Regardless if this hypothesis is true, high protein (meats and dairy) diets have been linked to osteoporosis.
Lists of calcium contents, comparing dairy with vegetables, often show higher values for dairy products. What these lists don’t tell you is that calcium from dairy is not as easily absorbed as from vegetal matters (fruit, vegetables, grains, legumes, nuts – everything that has really grown) because high protein hinders calcium absorption.
Don’t think you get much benefit from a calcium supplement! Number one, the calcium without the other minerals will not do you much good. Number two, as a physician I am all too familiar with that oblong white spot on an x-ray of the bowels – the not-absorbed calcium pill. You better put your money into fresh produce!
Did I mention movement for bone health? I should. Read More
