While perusing the internet I found some articles talking negatively about soy protein and how it will effect the growth while consuming it after workouts due to the estrogen prescence. I am allergic to whey egg and caesin so I am caught between a rock and a hard place. I just want to get good gains safely. ANy suggestions on good protein sources or if soy’s really all that bad.
Soy Isolate 95 and its benefits

Peanut butter, tuna, chicken, and BCAA’s. I don’t take a protein supplement aside from BCAA’s. If you are working as hard as most people are who are training for track, ie lifting and sprinting, you can do with the extra calories from getting your protein from animals.
Edit- soy has certain isoflavones such as diadzen which mimics estrogen. I stay away, but I don’t have nay studies to show proof that it hurts long term or short term development.

Well other than the previously mentioned animal sources, beans are a good source and there is also hemp protein.

I have seen some studies regarding soy, which were, on the whole, negative. My nutritionist also told me that taking a decent amount of soy per day (the equivalent of 2 soy shakes) was similar to taking the female contraceptive pill. So I stay away.
You can get pea protein too. I think most vegetable proteins are deficient in one or more amino acid. Pea protein is deficient in lysine (from memory), and so if you had pea protein + lysine you would be alright.
Have you tried whey isolate? Most people who dont get on with whey are allergic to the small amount of caesin found in normal whey – isolate removes that. Or just stick with the whole foods as mentioned by Josh.
Ya I’m definitely stopping my usage of this. Josh I am a baseball player looking to put some mass on with a lean body type so I’m eating pretty solid amounts of the foods. The guys at GNC were saying to take brown rice protein. I was hesitant because brown rice isn’t all that whole (correct me if I’m wrong). See I’m lactose intolerant with allergies to whey and eggs. Are amino acids worth a try?
