How much calcium in milk v. cabbage… per calorie is a spurious comparison, as to get 100 calories from milk you need only a large half cup, but to get it from cabbage you need three cups of cooked cabbage!

I listened to your lecture, and you have me convinced that taking calcium supplements is not good. However, I get a lot of leg cramps when I don’t take calcium. What are my alternatives? I try to stay hydrated, drinking at least 6 – 8 glasses of water a day which helps.

Dr. Jason Fung: Magnesium is often useful to reduce cramps.

I am not a doctor or scientist, but I have suffered years of leg cramps. After 67 years I discovered I have a genetic mutation for utilization of vitamin B12, making me B12 deficient. I have not had a cramp (18 months) since properly supplementing with vitamin B12. I tried, potassium, calcium, and many recommend foods without getting any relieve.

I also am not a doctor, but I used to get wicked leg cramps. The kind that just won’t go away and left me lying on the floor calling out to Jesus for help… Literally. I started supplementing with magnesium and viola! No more leg cramps. Since magnesium is essential in over 300 cellular functions, and virtually everyone is deficient because of depleted soils, there is much added benefit to magnesium supplementation. Look up the best kinds of magnesium to supplement with because they are utilized very differently in the body. For instance, magnesium oxide is excellent for aiding in… Read more »

re-milk products intake and cancer risk (not Ca++ supplements): what about cultures like the African Masai and the Mongolian Grassland peoples who eat a large portion of their diet in milk products? they have a LOWER incidence of cancer than western people. is that effect due to the milk products possibly being fermented and also Raw? in the case of Mongolian peoples, the milk consumed is often from sheep, elk and camels. perhaps that could account for some differences? or, is the correlation of milk and cancer actually based on something else? sugar and refined foods, not milk?

further, is it something in western milk that correlates with cancer? ie- synthetic growth hormones, toxins in feedlot feeds (see Monensin and Glyphosate as well as nitrates) exiting in the milk, ultrapasteurization, loss of cream (fat) top, and etc?

does cheese and other highly fermented milk products show the same cancer correlation? grass-fed products?
thanks!

A hair analysis show my calcium level very high and my manganese level to be very low. A little research indicates calcium blocks manganese and that manganese is needed for blood sugar regulation. It was recommend that I stop all diary and cut back vitamin D3 supplementation. I have taken this advise and will be testing again to see if the condition improves. I am worried that my high blood pressure may be caused by vascular calcification.

Sorry, dr Fung, but the argument ‘how many mammalian species: 5676, how many mammalian species drink milk after they’re weaned: 1, therefore humans should not drink milk’ is illogical. I could come up with a dozen equaly illogical arguments. how many mammalian species: 5676 how many mammalian species cook their food: 1, therefore we shoud eat everything, including beans with those yummy haemagglutinin , raw how many mammalian species: 5676 how many mammalian species plant their food in order to harvest them later: 1 (unless you count quirrels forgetting their winterstash and ants who ‘farm’ avids, but then, they’re not… Read more »

This diatribe against milk and calcium is, frankly, barking up the wrong tree. It’s not a question of how much calcium you’re eating that makes your bones either strong or brittle, it’s the amount your body actually uses to built bone. It’s not a case wether the protein in milk or whatever animal source (and boy, do I detect a bias toward veganism lately with all the red-meat-scare-stories and the milk-hatred I see everywhere, it’s almost as if big soy-bean-growing Big Agriculture has been subsidizing a lot of science) it’s a case of wether your body can actually use the… Read more »

…except the fermentation /mammalian species point:
wild carnivores, and some domestics like cats, eat the gut of their prey–their prey are mostly vegetarian animals; these organs have a large amount of fermented, pre-digested vegetable matter–wild grains, seeds, grasses, root and woody fibers. vegetation and carbs in this form enable these prey animals to get benefits from some of their (small percentage) of needed fibers, which they could not otherwise digest or metabolize well.
so humans plus wild carnivores=2 for the fermentation question… 🙂

Hey!

You are talking about the China study, but in the internet it is really easy to find lot of articles why that China study is not accurate and why it has been done badly. Have you read about this and what is your opinion. Is China study really trustworthy?

I am still listening to this, but it occurs to me that much of this effect you have statistically documented, could be due to the prevalence of the sun in different areas, and the variation in skin types. Darker people have more melanin in the skin and a greater ability to absorb the suns rays, and then synthesize vitamin D.

Ruben

You got that fact exactly wrong. The pigment melanin reduces the skin’s ability to make vitamin D in response to sunlight exposure.

I couldn’t help but feeling sorry for those people in audience, when I heard constant pops when they were opening their soda cans. They need to take more lessons from Dr. Fung about nutrition!

Also, I know it doesn’t explain it all, but one factor for more hip fractures in Scandinavia is ice. We walk on icy roads half of the year, and I work as a nurse, and most hip fractures happen during winter and on icy roads. In Scandinavia people walk a lot more than they do for example in US.

“Hey, Bozo the Clown” is going to get Jason ostracized by his fellow doctors. This is good because any health minded person who follows conventional medical “wisdom” will harm their health. Jason should realize that he is on a path to severe marginalization from the mainstream of medicine. He wears a stethoscope around his neck when he lectures, yet he says what he says. This is like this fictional analogy: Let’s say that all but a handful of Catholic priests molest young boys. And the handful separate themselves from the herd of child molesters and start screaming that their fellow… Read more »

where’d all the pseudo scientists come from. You want to argue with Dr. Fung?

I guess I tuned in to hear the man’s ideas?? guess I’m on the wrong website for that.

One thing I noticed about all the places where they eat dairy: they are all rich countries. Maybe carrying weights like they do in countries where they are poor is good for the bones. Plus people in the Nordic countries are adapted to drinking milk. Asian people are not adapted to drinking milk, they can’t have it because they can’t digest it.

A staple of the Mediterranean diet is Cheese and yogurt. The reason that was invented was to make milk more digestible. Those products have less lactose.

I pretty much think the calcium supplements are useless.

I am left wondering a few things, i.e. how much calcium is in plant “milk”s we make ourselves than the varieties sold fortified with unnecessary calcium and D? Is rice milk, seemingly the lowest calcium of all plant milks, still plagued with the arsenic scandals? And how about the high glycemic nature of rice milk? There is a big cost differential between non GMO and usually GMO soy milks and they seem even higher in calcium than cow’s milk. What about lactose free dairy products? Any difference? How about high lactose milks? http://www.bbc.com/news/magazine-40686373 What about milk products the result of… Read more »

Where in the world did the figure of 10 babies per female come from. It is completely false and shows sloppiness and puts into question other details in your lecture. I am disappointed, really!

Dr. Fung: How interesting that I found this on you tube last night. You don’t suggest this but I will. It has LONG been a theory of mine that calcium is an instigator of Insulin Resistance AND diabetes. People wonder why people are becoming resistant? Well what is another thing that has been pushed in our food for the last 20 years or so? Calcium. My theory is this, calcium that is supposed to get into your bones is being stuck out in your blood. Eventually getting to the cells. This messy gunk, stops up the insulin receptors. When you… Read more »
