So does anyone know the difference between protein and SOY protein? What is the difference? I am confused... Do we still get the same benefits from the soy protein vs. the "regular" protein.  Does soy protein count towards are required daily protein amount? I know, I know, so many questions. I am just full of them today! Hugs, Jaime

Hi Jaime, There is a lot of debate on the subject.  Some people say if it's not whey protein it doesn't count.  To other's it doesn't matter.  My surgeon was of the opinion that protein is protein and in the beginning Soy protein was what all my supplements where.  First I found them easier to digest and they tasted better.  The whey protein to me just had too much of that "fake" protein taste and I couldn't get any of the drinks down.  With soy protein I had no problem. Again, there are various opinions on the subject, but I have to agree with my doc....protein is protein. Steph

Thanks Steph, I am eating these soy crisps from Trader Joes and it says they contain 6grams of SOY protein per serving so I was just curious... Very interesting topic... Hope you are doing well my friend.  Jaime

Hi Jaime! I thought protein was protein too.  I agree with Steph.  I found Soy way better on my digestive system.  And, yes, it does taste better. Good luck to ya! Catt

Hi Jamie, My only catch with soy protein was because I have a thyroid issue.  The soy interfers with the absorption of my thyroid medication so my numbers were always off. Personally, if you don't have a problem with your thyroid and like Soy...eat SOY! 

I have been on the boards here for about 18 months...This is what I have heard (my 2 cents).  Whey protein isolate is easier to digest and absorb.  You really should go with it for at least the first 6 months to a year.  Since it absorbs better, it can prevent loss of muscle mass.  Once you lose muscle mass it is hard to gain it back.  The biggest problems that RNY people face with this issue is to find a whey protein we can stand to drink day in and day out.  Once that gets resolved it becomes an easy process.  I think of my whey drink as medicine and force it down.  When you have a chance, find other WLS patients who have different protein shakes and try and taste theirs.  You'll know in a few seconds which ones you like.  Again, other proteins are good, buy whey is the best.  Brian

  This is what I have heard and read hope this helps.

Whey Protein vs. Soy Protein

Athletes and Bodybuilders swear by it, but researchers are concerned about the potential effects of animal protein on the body. As a result, many are turning toward soy protein and whey protein instead. But, what are the benefits, drawbacks, and differences between these different forms of protein? And, how much should you include in your diet in order to garner the benefits you are looking for? Protein has been garnering extra attention as the health conscious realize the benefits of including protein in their diets. Protein is needed to help rebuild the body’s tissue, which is particularly important to athletes and bodybuilders. In fact, the body is in need of a continual supply of protein in order to repair and to build its tissue. Protein is also essential for producing antibodies, hormones, new muscle tissue, and blood hemoglobin. All protein that is lost within the body must be replaced and protein must be present in order for new tissue to be constructed. While athletes swear by the ability of animal protein to build muscles, researchers are concerned about the potential effects of animal protein on the liver and the kidneys, as well as the link between animal protein and osteoporosis. As a result, many are turning toward soy protein and whey protein instead. But, what are the benefits, drawbacks, and differences between these different forms of protein? And, how much should you include in your diet in order to garner the benefits you are looking for? Soy Protein Soybeans contain high quantities of protein (considered to be of equal quality as animal protein) and also contain substantial amounts of amino acids. In addition, soy has been observed to lower cholesterol. Even the Food and Drug Administration (FDA) has stated 25 grams of soy protein per day can reduce the chances of developing heart disease. Soy protein has also been found to reduce the symptoms of menopause, to reduce the risk of developing osteoporosis, and to help prevent a number of diseases related to hormonal issues. These include endometrial cancer, breast cancer, and prostate cancer. Soy protein has also been shown to speed up the metabolism of the thyroid, which can help with obtaining a leaner body. If you are intolerant to soy, however, its specific protein can actually have the opposite effect. A number of soy protein products can be found at health food stores, including food bars, soy burgers, and even soy-based beverages. Those products containing soy protein isolate generally have the highest saturation. Other products containing soy protein include soy flour, whole soybeans, and tofu. Be sure to check the product label in order to determine the amount of soy protein the product contains. Remember, however, soy isoflavones, which are sold as supplements in health food stores, are not the same substance as pure soy protein. Nonetheless, soy isoflavones possess a number of beneficial effects, such as improving kidney function and preventing bone loss. If you are not allergic to soy, there are very few side effects to including soy in your diet. In some people, however, consuming soy on a routine basis can lead to an upset stomach and may even cause diarrhea or constipation. Whey Protein Like soy protein, whey protein has been shown to provide a number of benefits. For example, clinical studies have shown whey protein can:

• Act as a natural antibacterial or anti-viral
• Assist in maintaining the proper weight

 The Whey Protein did not all show up sorry.  Here it is. Whey Protein Like soy protein, whey protein has been shown to provide a number of benefits. For example, clinical studies have shown whey protein can:

• Act as a natural antibacterial or anti-viral
• Assist in maintaining the proper weight
• Reduce the symptoms of Chronic Fatigue Syndrome
• Reduce liver damage
• Improve the function of the immune system
• Improve blood pressure
• Improve athletic performance
• Improve the function of the digestive system
• Reduce gastric mucosal injury

Whey protein is very high in biological value (BV), which is highly sought by athletes. In short, BV is the amount of protein your body can replace with 100 grams of consumed diet. The only other foods containing high levels of BV are whole eggs and egg whites. Unlike eggs, however, whey protein does not contain high levels of fat. While soy protein is derived from soybeans, whey protein is derived from milk as a diluted byproduct of the cheese-making process. Fresh liquid whey protein contains only about 1% protein because it is mostly comprised of lactose and water. For this reason, it takes about 229 liters of milk to produce just one kilogram of high quality whey protein isolate. While in its original form, whey protein affects the digestive tract in much the same way as yogurt. Therefore, it is considered to be a natural remedy for many intestinal issues. In fact, it is often used in Sweden to help prevent bowel problems, gas, and constipation. Nonetheless, it can have the opposite effect and actually lead to constipation for some individuals. The amount of whey protein recommended in a person’s diet depends on his or her weight, gender, age, level of activity, and overall health. Including both soy and whey protein in your diet can be very beneficial to your health; but, since both can lead to constipation, be sure to follow a high fiber diet to help keep your bowel movements regular. Try one or both of these all-natural health supplements and discover the results for yourself! The Colon Cleansing & Constipation Resource Center is sponsored by Global Healing Center, Inc.
