Protein is an important nutrient. Aside from its many benefits, it can also help you shed that stubborn weight you have been trying to lose for months, and make you feel full for longer hours. However, it is essential to control the intake of protein as too much of it can cause more harm than good. There are many sumptuous dishes that can supply you with proteins, regardless of the diet you need. Contrary to people’s opinions, healthy protein sources are not that expensive, there are lots of budget alternatives.

Why do we need protein?

There are plenty of benefits to including foods rich in protein to our diet because protein is essential for many bodily functions such as building muscles, tissues, and cells as well as helping produce anti-bodies and hormones. We all need proteins, but if you lift weights or are in strenuous sports, you may benefit from the additional intake of protein to help with the muscle building as well as healing and recovering.

A recent study also shows that older people can also benefit more from increasing protein intake because it reduces muscle loss linked with aging.

How much should we consume?

While different experts will give you a different answer, there are some golden rules to help you determine how much protein you should eat in a day. According to scientists, the minimum amount of protein required for the body to ultimately perform is 0.36 grams per day for each pound you weigh. This translates to about 46 grams of protein every day or more for an average woman, and about 56 grams for an average man.

Generally, the more you move around the more your body protein requirement, since the less wear and tear to subject your body to, the less repair and healing work there is to do. Your age will also come into consideration, as we have mentioned above, your body functions better with protein as you age.
