Protein is seen as one of the most essential forms of nutrients to support high levels of exercise. However, choosing the right type of protein can either further aid muscle repair or can potentially harm your body. Research done by a nonprofit group, Clean Label Project, has found that many protein powders contain heavy metals such as lead, arsenic, cadmium and mercury (commonly used in pesticides) which can link to cancer or other health issues. Generally, the more organic or natural the type of protein is, the more healthy and more benefits it will provide. There are, however, some types of protein powders that have added vitamins and minerals that are able to benefit muscle repair.
My favourite type of protein is pure isolated whey protein because of its high protein to weight ratio. Grant Tinsley, PhD in exercise physiology, states that whey protein isolate is 90% protein compared to whey protein concentrate which is 80% protein. Choosing a dense protein source can supply your body more quickly with the nutrients it needs after or before exercise.
Careful consideration must be taken before buying whey protein with added ingredients. A brand of protein I frequent used was whey protein with added green tea and pomegranate extract, shown below. Although some brands will add nasty chemicals into the protein to supposedly increase performance but some, like the one I use, can provide healthy benefits.
Be wise in your choices, in buying protein or for any aspect of your life. To be this wise many seem impossible, but following God gives your miraculous wisdom. This is said in Proverbs 2:6
For the Lord gives wisdom; from his mouth come knowledge and understanding.
