A good research, and study finds about dairy and meat products should not be taken in plenty, but it failed to tell about what specific kind of dairy and mear products, perhaps further study is going on and it is trying to find more exact and specific food items.

Excess consumption of Milk and its products and Meat were never Health friendly. And about exact quantity can never be defined as Human body construction varies from individual to individual. It's only through self experimentation what quantity is suitable and what not. In the place of Meat Fish is advised for better immune strengthening.

I also fel that it is better to eat eggs regularly and fish only in extreme winter cold.
