2. Cheese
Cheese is made of 20% whey and 80% casein. There isn’t any type of cheese that contains zero casein, so if you are allergic, you should totally scratch off cheese from your diet. However, if you aren’t intolerant to this protein it would be a great addition to your diet because it can help increase and retain your muscle mass.
3. Butter
As a dairy product, butter contains casein. Some of the popular types of butter are unsalted, salted, organic and whipped butter. Butter can be consumed in various ways. You can use it to cook dishes or make pastries. You can also spread it on a slice of bread to make toasts. While most of the types of butter contain a high amount of casein, some have very low amounts or zero casein such as ghee or clarified butter.
