The Power of WHEY Protein

This is a helpful blurb on 'whey' protein and protein, in general. Hope it helps.

The Power of WHEY Protein

Dear SCAN Members,

As a health professional, you understand the importance of including high-­quality protein in a healthy diet to help the body function properly.1,2,3 While most Americans meet the Institute of Medicine’s Recommended Daily Allowance (RDA) for protein—0.8g/kg of body weight/day—sub-­populations, such as active adults and the elderly, may benefit from higher protein diets.4,5 Despite common beliefs that most Americans over consume protein, on average, Americans’ protein consumption hovers at the lower end of the acceptable macronutrient distribution range (AMDR), which is between 10% and 35% of total daily calories for adults 19 years and older.6 In fact, data indicate the average protein intake for men and women is 16% of calories.6

A growing body of science supports the benefits of consuming a higher protein diet - especially for managing weight and recovering after exercise. Whey protein is a complete, high-­quality protein that is naturally found in dairy.

* Consuming whey protein may help:
o Promote muscle repair and recovery after exercise;7,8 and
o Build more lean muscle, when combined with regular resistance exercise, compared to resistance training alone or resistance training combined with carbohydrate consumption. 9,10
* Consuming whey protein, as part of a diet higher in protein, can help people:
o Feel fuller longer than carbohydrates or fats;11,12,13 and
o Lose more fat and/or maintain more lean muscle, as part of a reduced-calorie diet.14,15

To help your clients add more whey protein to their diets as they look for new ways to manage their weight and recover post-­exercise, the National Dairy Council has developed educational tools that are available for your use at These include:

The 'Whey' to a Higher Protein Diet: Using Whey Protein to Help Fuel Your Active Lifestyle (Whey Protein Booklet)

This booklet outlines the importance of protein and whey protein; helps readers determine protein needs; and includes recipes and meal plans.

Recipe Cards

These three healthy and simple recipes using whey protein provide quick and delicious solutions for including more complete protein in one’s diet.

We hope this information is helpful to you as you educate clients about the benefits of consuming high-quality protein every day.
