Pros
Helps Improve Body Composition
When taken in the right quantity and paired with the right amount of exercise, whey protein is guaranteed to make significant improvements in your body's compositions. However, this is not all, whey Protein is believed to contain antioxidants that help boost your immune system.
Enhances Recovery
Studies show that protein boosts carbohydrates acceptance. Meaning your glycogen stores will be replenished quickly. Furthermore, the protein in whey will support post-run muscle repair.
Fights cancer and age related diseases
It has been discovered that whey can fight some common forms of cancer such as prostate and colon. A recent study on rodents showed proof that there is an anti-tumour activity associated with whey protein.
Whey Protein also contains Gluthaione an substance known for energy production, energy utilization and combating diseases associated with aging such as Parkison’s and Alzheimer’s.
Cons
Being a byproduct of cheese, Whey Protein is the remnant of processed cheese and undergoes several stages including removal of fat and carbohydrates from the protein. The process includes the use of excessive heat which can denature the proteins. Whey protein processed using low temperature are superlative.
Excessive sugar and artificial sweeteners
Most whey protein is flavoured or coloured with artificial agents. It is a no-brainer that these ingredients can play a prominent role in the deterioration of one's health especially if you happen to be a diabetic or have any preexisting health problems such as high cholesterol levels.
Easy to Overdose
Whey Protein is sugary and does not have a specific dosage. Athletes may thereby think it is not a big deal to take more to achieve faster results. This however,is not valid and can lead to an overdose. Athletes are at liberty to take pre and post workout, but should not overstep their boundaries with a, ‘more is better' mentality.
Lactose intolerant
Being lactose intolerant means, you have a strong reaction to milk and any milk products, since Whey protein is a by-product of cheese which contains lactose it is assured to create some discomfort. A solution to this, whey concentrate which is just as good as whey protein but has all the lactose removed. Vegans are also not invited to this party as it made out of animal products and that goes against everything they stand.
Kidney Risk
Whey protein is feared to lead to kidney damage. However, is not entirely accurate. In individuals that have a history of kidney disease, high protein intake may cause them significant kidney damage ultimately leading to kidney failure. Healthy individuals need not worry about their protein intake.
