When it comes to dairy I personally took it out of my diet for over seven years. But what I found when I added it back in was shocking. I had no reaction what so ever. Now, that being said there are some people that are lactose intolerant. That is very different from a dairy sensitivity.
All my life I would get bad stomach aches after eating dairy. For me it wasn’t lactose intolerance but more so the type of dairy I was consuming. I would have heavily processed non-organic dairy. This type of dairy was filled with chemicals, antibiotics, hormones, and more, that made my thyroid ten times worse.
So when choosing if you should or should not eat dairy, you first have to analyze what type you are eating. When I added it back in I used raw, non homogenized, grass-fed milk. Instead of getting it from local grocery store, I chose a local farm. Raw milk is the most easily digested. If you can’t get your hands on that then you should try grass-fed, pasture raised, organic dairy.
Then I would see how you react to it. Sometimes it takes removing it for good amount of time to give your gut a break. But I do believe dairy is high in nutrition for the body. So if you have to remove it for healing, that is ok I been there. But it is not a must to be gone from your diet forever.
