Nutritional guidance
Nutritional guidance has been studied in 5 papers since 2021: 4 trials and 1 observational study in people; 2 in the past year. The newest paper, Feb 6, 2026: “Effects of a personalized exercise program on physical function in older patients with rheumatoid arthritis at high risk of sarcopenia: results of a randomized controlled trial”.

“Significant improvements were observed in oral function tests, specifically in oral diadochokinesis (ODK)/ta/and swallowing ability (RSST), particularly in the low-DVS group.”

Studies in people
2 studies gave nutritional guidance to people and measured what changed.

What did studies of Nutritional guidance find?
6Studies of Nutritional guidance measured 6 outcomes; the most studied are body composition (2 studies), oral function (2) and swallowing function (1).
Body composition

2 studies
Body composition
no changein humans2
Nutritional guidance has no effect on body composition in humans.
“On the other hand, no main effects or interactions between time and intervention were observed for body composition.”

Nutritional guidance has no effect on body composition in humans.
“Despite the improvements in dietary diversity, no significant changes in body composition were observed during the study period.”

Swallowing function
upin humans1
Nutritional guidance improves swallowing function in humans (F(1, 36) = 8.44, p = 0.006).
“Three months after baseline, oral function showed an interaction between time and intervention (nutritional guidance) in masticatory performance (F(1, 36) = 13.03, p < 0.001), maximum tongue pressure (F(1, 36) = 6.58, p = 0.015), and RSST score (F(1, 36) = 8.44, p = 0.006).”

Nutritional guidance improves maximum tongue pressure in humans (F(1, 36) = 6.58, p = 0.015).
“Three months after baseline, oral function showed an interaction between time and intervention (nutritional guidance) in masticatory performance (F(1, 36) = 13.03, p < 0.001), maximum tongue pressure (F(1, 36) = 6.58, p = 0.015), and RSST score (F(1, 36) = 8.44, p = 0.006).”
