Dairy and Osteoporosis / 乳製品と骨粗鬆症

I want to share one of the eye opening things I learned; the reason why taking milk and dairy food leads to osteoporosis. First, I must clarify the difference between animal protein and plant-based protein. The difference is that animal protein is hard to absorb in the body as nutrients but plant based can easily be absorbed. Dairy contains animal protein and is rich in calcium, however the calcium together with animal protein can't be absorbed by your body. Further more, it makes blood acidic. Human blood is about PH 7.2, which means a little alkaline. When blood becomes acidic, it tries to balance back to alkaline. As a result, the body starts collecting minerals ,yes, minerals from your bones which leads to osteoporosis. What is worse, there is another factor, where does calcium from dairy food go in the body? It remains in your body as calcifications, accumulating in your joints. Of course that contributes to joint problems. 
I never knew how exactly dairy food contributes to osteoporosis until now. Now it's  clear! Please take care of your bones.

牛乳などの乳製品が骨粗鬆症を招くことは近年では紹介されているので、理解されてきているようですが、そのメカニズムが理解できないままでいました。授業で学んでようやく理解できたのでここで紹介したいです。まずは動物性タンパク質と植物性タンパク質の大きな違いは、動物性タンパク質は体に栄養素として吸収されにくいということです。また動物性タンパク質は血液を酸性にします。人間の血液はPH7.2くらいで少しアルカリ性なのです。それが酸性になっていくと体はバランスをとるために自動的にそれをアルカリ性に戻そうとし、その結果体内のミネラル分を溶かして血液に入れていきます。そう、骨からミネラルを抽出するのです。それが骨粗鬆症を招くのです。それだけではなく、体に栄養として摂取されないまま残ったカルシウムは一体どこへいくのでしょう。それは関節や、頭蓋骨の隙間に蓄積されます。これが蓄積されていくと当然、関節などに障害が起きはじめます。どうか、骨を大切にしてください。納豆、ごま、豆類、ブロッコリーなどの野菜や海藻からカルシウムを摂取するとよいでしょう。

  1. Hi. This is very interesting. I wish more people were aware of this. I wonder how calcium is absorbed and processed in our bodies when taking pills. My Dad has recently stopped drinking milk and he takes a calcium pill. My whole family takes a multi-vitamin daily (w/calcium in it), including me. Can you ask your teachers about calcium in vitamin supplements?
