If I do not have a milk allergy, can I drink whey protein powder shakes?

Yes. Whey is a dairy component so you shouldn't have a problem. Be sure to carefully consider what your goals are for the supplement. Some are high in carbs - others more protein. Always drink LOTS of water to keep up good urine flow to avoid kidney irritation if too much protein in your diet. http://www.webmd.com/diet/protein-shakes.
Yes. In the case of milk allergy, you are allergic to milk protein. This includes both the whey and the casein. It would be safer for you to chose a soy or other alternative protein shake. If you want more protein, you could increase your food intake of non-dairy proteins. Use caution with any protein shake. Consuming more than 60g of protein/day can cause kidney irritation and damage over time.

Can my dad use protein powder in his shakes if he is diabetic? He likes the idea that it will give him "strength". Can he take whey protein?

Protein is OK. The protein will be fine. It will not spike his fingersticks. As long as there isn't something else in his shakes or whey that could harm him or raise his glucose levels. In fact, a protein and non-starchy vegetable diet can help diabetics control their glucose levels. Read more...
Yes.. Keep an eye on the sugar and carbohydrate levels in his shake, and monitor glucose until you can see what effect the shakes might have. He may need to adjust your diet or your medications, depending on findings. This assumes, of course, that he has adequate kidney function.. Best Wishes ! Read more...
