Calcium levels are more affected by your acid/akiline balance than dairy intake. If you get enough green veg, don't worry about calcium.
Soy can stimulate estrogen production, not something you want. The way Aisians eat soy is fermented, not as a meat/dairy substitute. Fermented soy does not have any negative aspects when eaten in normal qtys.
I've actually done the calculations myself. You can completely eliminate dairy, grains and processed foods from your diet and still get all the nutrients you need without resorting to supplements and soy substitutes, just eating a variety of normal vegetables, fruits, berries, meat, nuts, oils and herbs. It's the way our ancestors ate and it still works.
OK sounds good. I tend to eat about 500g of frozen veggies a day anyway, calcium was one thing I was worried about but it looks like i shouldn't worry.
On the subject of veggies ... I don't know how but after 500g you are stuffed but still feal hungry having only consumed about 150kcal.
