People need to consume protein in a limited amount and its over-consumption can lead to many problems. Consumption of protein in high amounts can overtax the kidneys and lead to conditions like gout.
Vegetarians who consume protein-rich food receive sufficient proteins and amino acids. Seeds, beans and nuts along with vegetables like broccoli, spinach and green peas can be a good source of protein.
Although cheese is high in proteins, it is filled with calories, sodium and cholesterol-raising saturated fat, which are not good for the heart.
Consumption of not all kinds of meat leads to cancer. It is believed by doctors that red meat and processed meats like bacon, sausage, ham, and jerky carry the risk of causing cancer.
A lot of protein powders and bars are highly processed and contain preservatives, colours and sugars, and hence, they are not always the best way for protein intake.
