Try the Blue Plate Special, when Mom Won’t Eat

Try the Blue Plate Special, when Mom Won’t Eat

When managing appetites among Alzheimer’s patients, caregivers might want to consider what’s under the food as well as what’s in it.

Supporting the expression that “we eat with our eyes,” Boston University researchers in 2004 found that meals served on top of brightly colored plates prompted diners with dementia to eat more.

If there’s somebody with contrast-sensitivity loss and they’re suffering from not eating enough, it’s worth trying.

“And it’s cheap. This is not an expensive intervention. You can even use plastic.”

One group of nine elderly Alzheimer’s patients increased consumption by an average of 25 percent after blue plates and cutlery replaced their old white or stainless-steel tableware.

Cranking up the visual contrast seems to be key to boosting caloric intake, said BU psychology professor Alice Cronin-Golomb.

It probably has to do with making the food stand out visually, she said.

Significant weight loss affects 40 per cent of patients with Alzheimer’s disease. While diminished appetites could be attributed to depression, confusion or physical limitations, the BU team had another theory.

“Maybe one reason people aren’t eating as much food is because they can’t see it. And if they weren’t seeing it, they weren’t eating it,” Cronin-Golomb said.

It’s the reason the U.K.’s Salisbury District Hospital, in a bid to curb hospital malnutrition, upgraded its old white dinnerware for blue plates last year. Patients reportedly ate one-third more after the switch.

Cronin-Golomb said many long-term care facilities dole out food that’s pureed or mashed so it’s easier to chew. Most of those dishes appear white or beige, often served with a cup of milk to boost calories.

But if you’ve got white milk and a white cup, you can’t really see it.

When the BU researchers introduced red cups, plates and cutlery to a group of nine elderly Alzheimer’s patients at a care facility in 2004, the patients ate 24 percent more and drank 84 percent more. The presence of blue table settings boosted food consumption by 25 percent and liquid consumption by almost 30 per cent.

Cronin-Golomb explained that as adults age, they lose “contrast sensitivity,” or the ability to discern between “an object and its background.” While healthy older people only lose high frequencies (requiring us to need reading glasses), the loss of contrast sensitivity is more severe in Alzheimer’s patients and goes across the frequency range.

To bolster their belief that the color of the tableware is not as important as creating a vivid contrast, the BU team repeated the study with pastel plates, but food and beverage intake was similar to when the white tableware was used.

The researchers noted that choosing a plate color should be dependent on the type of food being served. Tomato sauce will not be as visible against a red plate, obviously.

The importance of other visual cues for dementia patients shouldn’t be ignored, said San Francisco-based dietitian Heather Schwartz, who writes for the elderly care website A Place for Mom; aplaceformom.com

Design in the works

One U.S. student recently won a design prize for her seven-piece set called Eatwell.

Sha Yao from the Academy of Art University in San Francisco won the $10,000 first place prize for her project, which involved the design of tableware specifically for people with Alzheimer’s, including coloring the interiors of the tableware blue.

What’s more, Yao designed a slanted bottom that eliminates the need to tip bowls to get at the last bits of food. The cups have low centers of gravity and are difficult to knock over.

“The beauty is in the way that small design decisions were made with intentionality and with lots of testing with actual users. It is a wonderful example of user-centered design,” said a Stanford University spokesperson.

Yao said her late grandmother had Alzheimer’s, and that served as her personal motivation for the project.
