Whey Protein and Diabetes: What You Must Know?
Whey protein has become one of the most popular nutrition supplements today, used not just by athletes, but also by people to stabilise blood sugar, manage weight, and improve muscle health. Here comes our question: Whey Protein and Diabetes? Let us find out.
What Is Whey Protein?
Whey protein is a high-quality protein that naturally comes from milk. When milk is curdled to make cheese, it splits into two parts:
Curd – the solid portion used to make cheese
Whey – the liquid portion, which is dried and processed into whey protein powder
That is how whey protein is made, a clean, natural protein separated from milk during cheese-making.
What are the Types of Whey Protein?
- Whey Protein Concentrate (WPC):

- Has small amounts of carbs and fats
- Mild taste, commonly used for general fitness.
- Whey Protein Isolate (WPI):
- Contains 90%+ protein
- Very low in carbs, fats, and lactose
