My children hate milk but love yoguart. I buy plain whole yoguart (no sugar or artificial sweeteners added) and add whole frozen blueberries. Delish!
Give it a try.
Soy is not a good alternative (contrary to popular belief). Avoid it like the plague...it is hormone disruptive and can wreak havoc on the reproductive system.
Almond milk is good but read the label and watch out for lots of added ingredients. Unsweetened Almond Breeze (original flavor) is one my children have occasionally.
Coconut milk is fantastic!
Go to a local health food store and do some research.
Calcium rich vegetables, like broccoli are a staple in my household.
Anything fortified with vitamins should be avoided (fortified = synthetic or unnatural).
Juice (unless organic and freshly squeezed and given just a small amount) is not healthy in the least. It's a marketing LIE!
The same is true about milk...unless it comes straight from the cow and unprocessed.
Get your vitamin D from the sun.
A couple of good online resources for info are Dr. Mercola and the Health Ranger. Google these guys, sign up for their newsletters, and be blessed.
Hope these suggestions help.
