“The probability of all-cause mortality was significantly lower in the intervention group (n = 8, 12%) than in the control group (n = 18, 29%) (hazard ratio = 0.36 [95% CI = 0.16-0.86]; P = 0.01).”

What did studies of texture-modified diet find?

Studies of texture-modified diet measured 3 outcomes: nutrient intake, handgrip strength and aspiration pneumonia.

Nutrient intake

1 study

Texture-modified diet improves nutrient intake in humans (dysphagia in community-dwelling older adults).

Handgrip strength

upin humans1

1 study

Texture-modified diet improves handgrip strength in humans (oropharyngeal dysphagia) (P = 0.02).
“Changes were observed in protein consumption (P = 0.01), body weight (P = 0.04), body mass index (P = 0.004), handgrip strength (P = 0.02), and phase angle (P = 0.04) between the treatment groups.”

Aspiration pneumonia

no changein humans1

1 study

Texture-modified diet showed no clear effect on aspiration pneumonia in humans (oropharyngeal dysphagia) (7.9% vs 16.1% (not significant)).
“There were 5 (7.9%) and 10 (16.1%) aspiration pneumonia events in the intervention and control groups, respectively (not significant) in 12 months of follow-up.”

What is texture-modified diet linked with?

Studies link texture-modified diet with 2 measures: aspiration and mortality.

Aspiration

Enhanced swallowing care had some early benefits in older adults

In a randomized trial, 600 hospitalized adults with swallowing difficulties received one of two care programs; most differences were no longer evident at six months.In a randomized trial, 600 hospitalized adults with swallowing difficulties received one of two care programs; most differences were no longer evident at six months.
