Research backs protein at breakfast, lunch too

Research backs protein at breakfast, lunch too
Most Americans eat the largest amount of beef or protein at the evening meal, but studies suggest it makes sense to spread intake over the course of the day

Research shows that balancing protein throughout the day makes good nutritional sense, but Americans eat about two-thirds of their total daily protein at the dinner meal – offering little room for protein in breakfast, lunch or snacks.

Through the Beef Checkoff, the beef industry is working to educate consumers on the value of balance and adequate protein intake.

"The imbalance of protein meals is an issue," according to Stuart Phillips, Ph.D., a professor in the department of Kinesiology at McMaster University in Ontario, Canada. "High-quality protein of sufficient quantities and evenly spaced is key to gaining or maintaining muscle mass."

Phillips, a recognized researcher focusing on the nutrition and exercise factors that affect muscle protein, says the elderly especially are in need of more protein per meal to stimulate protein synthesis and muscle generation. An optimal intake for robust stimulation in older men is 42 grams per meal, or what is provided by about 6 ounces of cooked 85% lean ground beef.

According to Heather Leidy, Ph.D., assistant professor in the Department of Nutrition & Exercise Physiology at the University of Missouri, not only is protein important, but the time of day protein is consumed could be significant.

"Protein at breakfast appears to be a good target to increase protein intake," Leidy says. "A high-protein breakfast seems to reduce food craving-based neural signals, and improve overall diet quality."

One checkoff-supported study, conducted by Leidy, found that daily consumption of a higher-protein breakfast that included two eggs and 1.5 ounces of beef was superior to both a normal-protein breakfast that featured milk and cereal or skipping breakfast altogether, in terms of improving appetite control, curbing food cravings and reducing unhealthy snacking in overweight or obese teenage girls who routinely skip their breakfast meal.

The research was featured in the American Journal of Clinical Nutrition in 2013 and in the Nutrition Journal in 2014.


30 Day Challenge
This line of research has led to additional research on the timing, quantity and quality of protein intake and its impact on appetite and satiety, along with the development of novel dietary strategies and recommendations.

A disparity in the timing of protein consumption could contribute to health issues such as muscle loss, as well.

A study on protein intake among the elderly, supported by the Beef Checkoff Program, demonstrated that consumption of both total and animal source protein was skewed heavily to the dinner meal. That could mean a disparity in quantity and quality of protein among the other meals. The study was published in the Journal of the Academy of Nutrition and Dietetics in 2013.

The research on balancing protein throughout the day provided impetus last spring for the beef industry's 30 Day Protein Challenge, a step-by-step way to get the optimal amount of protein across all meals.

The challenge encourages consumers to eat 30 grams of protein at every meal to help them maintain and/or build muscle, control food cravings and generally provide better overall health and wellness.

The Protein Challenge would help them take control of their appetite and kick-start the benefits of balancing protein consumption.

Consumers who sign up for the challenge receive daily inspirational e-mails, tools to help them succeed and delicious, nutritious beef recipes with plenty of protein. While the 30 Day Protein Challenge was officially kicked off last April, consumers can start anytime and receive the 30-day plan.


Thousands of consumers have since become active in the 30 Day Protein Challenge program, with a website landing page becoming the most visited page on Tens of thousands of visits have been made to the page, thanks to state beef council and national efforts to promote it.

It was the research, however, that gave the program its value and credibility.

"Research has always been a cornerstone of our efforts to encourage better nutrition among consumers," according to Jennifer Houston, chairman of the Federation of State Beef Councils.

"As we learn more about the benefits of protein consumption throughout the day, we can share those with thought-leaders and others who are helping consumers enjoy optimal nutrition. Making sure people have the proper amount of high-quality protein at the right times is certainly one way we can improve nutrition nationwide."

Houston says it's also a way to continue to stress the value of beef in the diet. She says the educational and research efforts are a natural fit. "Without research, our promotions and educational efforts wouldn't be effective or believable," she says. "Our emphasis on research is how we find out as much as possible about protein, and that's evidence that what we do is based on what we know to be true."
