Hi M.---I am a reformed cows milk drinker who now believes that cows milk is for baby cows. Through wellness classes I am taking from a Naturopath who has her PhD in nutrition, I've learned that cows milk is a highly allergenic substance and causes a bunch of problems in the human body. Most of them are so subtle, that milk is never looked as as a possible culprit.
But, please don't take my word for it. Please explore the website www.strongbones.org. There will be additional information at www.pcrm.org. And I would recommend reading The China Study by T Colin Campbell.
Be sure that soy milk is organic. I prefer almond as it has fewer carbs than rice milk. At 1 year of age, your baby is probably eating table foods. Dark leafy green veggies have lots of calcium. I have lots of info I could share, lists of high calcium foods, serving suggestions for different ages, shopping charts, etc. that I've collected as a result of my studies. Contact me at any time and I'd be glad to help. In fact, I would like to invite you to a health education lecture tomorrow night in Troy, MI. Dr David Phillips, Atlanda GA, will be talking about how diet impact athletic performance, but that advice is the same as for cancer prevention, etc. Let me know and I will share the details. Take care and good luck, D.
