Adherence
Age-related declines in taste and smell acuity reduce dietary variety and palatability, which contributes to reduced energy intake and impaired energy regulation in older adults.
Enhance the flavor, smell, and variety of your meals. Since your senses may be duller, use spices, herbs, and diverse textures to make food appealing, which can help stimulate the cephalic phase of digestion and encourage adequate intake.
GoodSupportsHIGH confidence
There are well-documented age-associated declines in taste and smell sensitivity... If the losses in taste and smell associated with aging have an equivalent effect (i.e., making food seem more bland)... the anticipated decrease in gastric emptying and likely delayed absorption of nutrients could help explain the reported increase in satiation and decrease in hunger in old age.
Why this rating
Supported by multiple studies on sensory thresholds and food intake.
