Moms always tell you to eat something with protein in it, but how much should your daily intake be?

The FDA recommends 50 grams of protein per day for people 4 years and older. You will find the number of grams of protein per serving on the “Nutrition Facts” labels on most foods. For example, a cup of black beans contains about 15 grams of protein.

The FDA recommends between 60 and 65 grams of protein for pregnant women or nursing mothers.

You didn’t state your activity levels.

True, the basic guidelines for most healthy adults are around 50–60 grams per day, but there are many exceptions to this rule!
Firstly, all proteins have different biological values and specific amino acid profiles. Some ptroteins are complete proteins, containing all of the essential amino acids (the ones your body cannot synthesize).

The order is as follows.

1. Whey protein has the highest biloical value of ANY protein (104)
2. Egg albumen (around 98)
3. Casein or lactalbumen.

Then come most meats etc. Soy is not a good source of protein, no matter how much all of the grazers out there make it out to be. Soy’s big claim to fame would be no cholesterol and a very high concentration of BCAAs (branched chain amino acids)

People involved in heavy/intense anaerobic activity such as powerlifting (me) or bodybuilding will have much higher protein requirements. The timing is as of as much consequence as the amounts.

In order to retain a positive nitrogen balance, a weight trainer needs to consume 1–1.5 grams of protein per pound of lean body mass. Staying well hydrated is necessary,too.

I know this is an old thread but, I eat 170g a day

It all depends on what your goals are. 60g is perfectly healthy, but if your like me who’s goal is to stay lean year round a high protein/mod carb/mod fat diet is what I follow…where as the FDA recomments high carb/mod fat/low protein
