2 senior adults having lunch

“When it comes to aging, older consumers want to hold back time,” says Anne-Sophie Vercruysse, Global Marketing Manager for Plant Proteins at Roquette. “They’re worried about losing mobility and independence. They want convenient and tasty food products that help them maintain or improve their health conditions.”

How much protein do you need to be healthy? The answer depends on your age. Older adults need more – and getting it can sometimes be a challenge.

One 2015 study showed that NUTRALYS® pea protein can help.

“We know protein is essential in our diets,” says Laetitia Guérin-Deremaux, Head of Nutrition and Health R&D at Roquette. Most healthy adults, she says, need to eat 0.83g of protein for every kg of body weight according to the Food and Agriculture Organization of the United Nations. That’s a daily target many of us exceed easily.

But for seniors, the target is higher. Older adults need between 1g and 2g each day for every kg of body weight in order to maintain good health. As we age, hitting that increased nutrition target can become a challenge.

“For elderly people, it’s not always easy to eat that much protein,” Guérin-Deremaux says. “They may have challenges with mastication. They may not enjoy chewing a big piece of meat, for example.”

Alternatives like yogurt can help, she says. But diet is about variety – and the more high-protein options that are available to seniors, the easier it will be for them to meet nutritional goals.

“In nursing homes, some seniors eat only half of what’s on their plate,” adds Vercruysse. “To fight malnutrition, the first focus is on delivering adequate nutritional support. But food is also a source of joy. Adapting the taste and texture of protein-rich foods to the preference of consumers with altered sensory sensations can play a key role in increasing their food intake.”

Could NUTRALYS® be an option for settings like these? Roquette scientists wanted to find out.

Letting the appetite decide

Offering protein-rich foods would mean nothing if those foods weren’t also good to eat. So Guérin-Deremaux’s team set out to design a study* that would test how likely seniors were to freely choose a NUTRALYS®-enriched treat over time.

They partnered with CEN Nutriment, a research firm in France, to offer protein-enriched food to adults between the ages of 70 and 90 who lived at nursing homes. Every other day for 21 days, those seniors who volunteered were served an apple compote enriched with NUTRALYS® protein as part of their lunchtime meal, providing 6.4g of protein per serving size.

Volunteers were free to eat as little or as much as they wished. Researchers measured how much was consumed each day, and volunteers completed surveys about once a week to indicate whether they liked the food.

One hope, Guérin-Deremaux says, was to challenge the perception many have that pea protein does not taste pleasant. If the volunteers ate it consistently for 3 weeks, her team would have evidence that seniors enjoyed NUTRALYS® enough to choose it regularly.

And that would show it could be an option for helping them eat more healthfully in the long term.

A consistent choice

That’s just what the 3-week study showed. After the first meal, more than 90% of those seniors surveyed described the NUTRALYS® compote as “rather pleasant” or “very pleasant.” In follow-up surveys over the next 21 days, about 80% continued to give the treat that high evaluation. Seniors didn’t just enjoy the compote once – they were happy to eat it consistently.

The portions they consumed were key as well. Each volunteer was offered a 125-gram serving of the compote, Guérin-Deremaux says. Most of the time, they ate about 80% of the serving offered.

That’s a healthy, easy-to-eat portion of protein these aging adults might not have had in their diets otherwise.

And that means seniors have one more viable option when they’re looking to increase the amount of protein they eat.

“The global conclusion is that this high-protein compote was well accepted by volunteers,” Guérin-Deremaux says. “NUTRALYS® is a real option for the elderly.”

The 2015 nursing home study was published in Aging Clinical and Experimental Research, an independent peer-reviewed scientific journal.
