Re Calcium and dairy.
I do eat some cream butter and some cheese, no milk tho'.
There are lots of points to consider when choosing to eat dairy or not. Firstly, after you remove it from your diet completely, for a couple of months, how do you feel if you eat it? It is actually normal to be lactose intolerant to some extent, milk is for babies, it is not for adults!
Some people can drink quite a lot of milk with no digestive upset, others only small amounts. Cream, cheese and butter may be ok for most people, but the whole calcium thing is bollocks- nobody needs to eat dairy foods "for the calcium". Actually high dairy diets in adults are associated with losing bone density!
Veg, leaves and meat all have calcium, meat, fish, eggs, seeds, nuts have magnesium, vit D and other things needed for building strong bone - calcium is almost never the limiting factor in bone building.
Otoh, eating grains (which have a high phytic acid content), strips minerals out of the diet (the phytic acid needs to be processed by the liver to get it out of the body as it is toxic), and in particular magnesium - the body will even break down existing bone to help process the phytic acid, leading to thinner weaker bones. This effect is seen in societies with the highest consumption of grain foods... White rice although it is a grain, is less of a problem, interestingly in societies which traditionally eat white rice that have recently moved to a diet based on wheat and other grains, bone strength drops, osteoporosis increases, teeth are weaker.
Interesting stuff, given the official dietary advice obsession with eating 50-60% "healthy whole grains" and lots of (fat free) dairy.
If you ditch grains, that's good news for your bones and teeth!
If you drink milk- be aware that its strange stuff- it has a big effect on blood sugar, much more than you'd think from looking at the carb content. Also, it is full of growth hormones( natural ones in the UK but injected artificial ones in many other countries), these hormones may cause cancers. Possibly a lot of these issues are due to pasteurisation and especially the UHT process which may make milk a lot less healthy- but good luck trying to find real raw milk to buy- I would be tempted to use some if I could find any locally.
But... It is infant food, and we don't NEED to eat dairy at all.
