What Is Whey Protein?
Whey protein is a natural product that contains very high quantities of protein. Protein is used by the body to convert nutrition into energy and muscle tissue. Whey protein in particular is seen as very beneficial because it contains branched chain amino acids. Whey protein is found in milk, together with casein protein. When milk is turned into cheese, whey protein is released as a by product.
Benefits of Whey Protein
There are four main benefits to using whey protein. The first is that it allows your body to better digest fat. If you quickly need some protein, it is incredibly useful because it usually comes in a powdered form. It should therefore be taken just after (no more than 30 minutes) a heavy workout. This is so that your body does not produce any cortisol, which is a stress hormone that stops your muscles from growing. This is also a reason as to why you should consume it on the morning.
The second of the whey protein benefits is that whey protein makes for a great snack. Bodybuilders who are working out should consume nutritious food every few hours. However, eating fully nutritious meals as much as that is very difficult. Instead, they will turn to whey protein shakes or bars.
Thirdly, whey protein is excellent for the immune system thanks to the glutathione. This is also beneficial for resistance training. Glutathione is so important that most surgeons now suggest their patients consume whey protein following surgery.
The fourth and last of the whey protein benefits is very beneficial for those trying to lose weight. However, it must be a protein shake or protein bar that is low in carbs.
However, as much as these benefits may make you want to your nearest holland and barrett store, it is still best to also be very aware of the dangers of whey protein. This would not be a fair whey protein review without also looking at the dangers.
Dangers Associated with Whey Protein
There are three main whey protein dangers that you should consider before turning to this product. The first of the whey protein dangers is the risk of sweeteners. Sweeteners are highly controversial, since they were initially all approved and people are now finding that one after the other is starting to be taken off the market due to inherent dangers. The main dangerous sweetener at present is aspartame. Luckily, this is not found in whey protein, but whey protein certainly does contain sweeteners and it is unknown whether these will turn out to be harmful over time. You could, of course, opt to use unsweetened whey protein.
The second of the whey protein dangers is the stress you place on your kidney and liver. Because these organs metabolize protein, it is believed that consuming high levels of protein may cause stress to the liver and the kidney. This, in turn, could be a catalyst for liver or kidney problems. Hence, it is not recommended for people with pre-existing kidney or liver problems to consume whey protein.
Lastly, there is the lactose issue. Because whey protein comes from milk, it contains lactose. If you are lactose intolerant, you should avoid whey protein, as it will cause a reaction. However, some people who are lactose intolerant are only allergic to certain parts of lactose and may not notice and whey protein side effects. It is best to speak to your medical professional about this issue.
In conclusion, whey protein for weight loss should be perfectly safe and there are not many whey protein side effects. However, if you have a pre-existing medical condition, you should always consult with your doctor first.
