Are products like cottage cheese, cheese, yogurt healthy if they are organic and grass-fed or raw even? Is there any harm in eating it everyday?
The vastest majority of ingredients are neither healthy nor unhealthy. Diets become healthy, based on what they contain, in what amounts. Cottage cheese, cheese, and yogurt, are perfectly normal ingredients. There’s nothing unhealthy about including them in your food.
They do have some good nutrients. They also lack others. It would also be possible to overconsume them, cheese especially, because it is very calorie dense. As a result, it’s not possible for anybody to tell you whether your diet is healthy or unhealthy unless you told us what else you’re eating.
