Egg Whites Pack Protein, but Leave the Calories Behind
Experimental Biology Research Preview
OMAHA, NE--(Marketwired - April 18, 2013) - More than 66 percent of Americans eat eggs for breakfast at least once per week[1], and new research presented by ConAgra Foods, Inc., (
Researchers found that a portion of egg whites that had half the calories of two whole eggs was just as filling. In fact, those who ate 70 calories-worth of egg whites -- in the form of Egg Beaters -- as part of their breakfast instead of 140 calories worth of whole eggs actually kept the calorie savings through lunch. .
"Previous studies have shown that whole eggs are more filling than a high carbohydrate breakfast food, like a bagel," says Kristin Reimers, PhD, RD, Nutrition Manager of ConAgra Foods. "This new research shows that egg whites at half the calories are just as filling as whole eggs, which suggests that egg whites are an excellent choice for a light breakfast that will keep you just as full as a higher calorie whole egg or bagel breakfast."
As much protein and volume, fewer calories
The egg whites were a filling food choice because even at half the calories they provided as much protein and volume as the whole eggs. Since egg whites provide fewer calories per serving than whole eggs, swapping egg whites for whole eggs at breakfast can lead to a lower total calorie intake throughout the day. In the study:
- 53 men and women were asked to eat a breakfastcontaining scrambled egg whites (70 calories) or two large scrambled eggs(140 calories). Both breakfasts were served with toast and a beverage too.
- Throughout the morning, participants were askedto rate their level of fullness, hunger, satisfaction and desire to eat.Three hours after breakfast they were served lunch and invited to eat asmuch as they wanted.The amount of calories consumed during lunchwas measured. They found that there was no difference between groups inthe amount of calories eaten at lunch.
- The study found that the Egg Beaters breakfast,containing Egg Beaters with half the calories of the portion of wholeeggs, was just as filling and satisfying throughout the morning as thewhole egg breakfast.Because the participants eating the lowercalorie breakfast didn't eat any more at lunch, the lower calorie benefitof Egg Beaters stuck with them even after lunch.
"This research confirms the advice I have been giving my clients for years," says Tara Gidus, RegisteredDietitianand Nutritionist. "Egg whites provide the perfect breakfast option for those trying to manage their weight. You can eat the same portion, for less calories than whole eggs, and the protein helps to ward off hunger pangs until your next meal."
A serving of lycopene
In addition to the egg white study, a second healthy lifestyle study was presented at the Experimental Biology conference that extends beyond the breakfast hour. It suggests practical implications for those who want to increase their consumption of lycopene. This red pigment is found mainly in tomatoes, and has been studied extensively for its role in maintaining heart health. The study found that:
- People who increased their tomato intake toinclude one cup of canned tomatoes, sauce or paste every day for six weekssaw an increase in the amount of lycopene in their bodies.
- This serving size of tomatoes is consistent withthe United States Department of Agriculture's (USDA) MyPlaterecommendations, and shows that eating in accordance to the recommendedlevels leads to increased levels of lycopene.
"Tomatoes are the main source of lycopene in the diet," says Reimers. "The results of this study indicate that eating the equivalent of one cup of canned tomatoes per day will not only help you to meet the USDA's dietary recommendations for red and orange vegetables, but also provides a significant amount of lycopene to the body. Examples of this amount include 1 cup of pasta sauce, a bowl of tomato soup made with 1 cup sauce, or a bowl of chili with cup tomato paste plus cup diced tomatoes. Research indicates that higher levels of lycopene are related to heart health in men and women, so this very simple (and delicious) habit can go a long way in terms of health promotion."
