Protein is definitely having a moment. Protein-laced products are everywhere: you can order a coffee topped with protein foam, have a glass of protein-infused water, and even snack on high-protein chips.

With all the hype surrounding protein, let's take a closer look at some common misconceptions and share practical takeaways you can trust.

How Much Protein Do You Need?

The word "Protein" bounces onto the tray of a food scale whose digital display says "??? grams"

The answer depends on factors like your age, overall health, and medical history. For most people (we’ll cover some key exceptions in a moment), the Recommended Dietary Allowance (RDA) is a helpful baseline: about 0.4 grams of protein per pound of body weight—which means that a 150-pound person would need around 60 grams per day.

Who Might Need More?

Some people may benefit from higher protein intake—especially those with increased muscle breakdown or intense physical demands, such as:

Serious weightlifters
Older adults experiencing muscle loss
People who are pregnant
People recovering from serious illness or surgery

In these cases, daily protein requirements can climb to as much as 0.6 grams per pound of body weight—or even more. Since needs vary, working with a nutrition professional can help ensure the right amount for your situation.

The Source of Your Protein Matters

It’s a common myth that plant proteins are “incomplete” or inferior. In reality, if you eat a variety of plant foods throughout the day, you can easily get all the essential amino acids—the building blocks of protein.

Although protein can come from many sources, research consistently shows that shifting toward more plant sources of protein is associated with a lower risk of heart disease, cancer, and other chronic conditions.

Not all protein sources have the same impact on health. In general, plant proteins have the best health profile, followed by fish, then poultry, then red meat—with processed meats (like bacon and sausage) posing the greatest concern:
