There is a close relationship between an individual’s perception of umami taste and that individual’s physical condition. Our newly developed umami taste sensitivity test revealed the loss of only the umami taste sensation with preservation of the other four basic taste sensations (sweet, salty, sour, and bitter) in some elderly patients. All such patients complained of appetite and weight loss, resulting in poor overall health. We also found that treatment of hyposalivation diminishes…

Use of monosodium glutamate in foods: the good, the bad, and the controversial side
The revised studies showed that MSG can reduce the amount of sodium in foods without modifying flavor, and the use of MSG is widely applied in industrial and homemade food.

Important role of umami taste sensitivity in oral and overall health.
Sensitivity to umami taste seems to contribute to good overall health in elderly people, and as a treatment for taste disorder patients, improvement of salivary flow has been adopted in the clinic.
Application of umami taste stimulation to remedy hypogeusia based on reflex salivation.
Enjoying taste should be one of the greatest pleasures in human life. However, aging is sometimes associated with decreased taste sensitivity, also known as hypogeusia. The loss of taste not only
Development of an Umami Taste Sensitivity Test and Its Clinical Use
A clinical test for umami taste sensitivity using a filter paper disc with a range of six monosodium glutamate (MSG) concentrations, which concluded that the RT of the anterior tongue was higher than that of either the posterior tongue or the soft palate in both young and older individuals.
Salivary secretion induced by umami taste.
The taste effectiveness of umami substances was evaluated by comparing the volumes of human salivary secretions by umami substance to volumes induced by other taste substances (i. e., sweet, salty, sour and bitter); and the differences between the effects ofUmami stimulation when applied to the anterior part of the tongue as compared to application to the posterior portion of the Tongue.

Saliva protects the taste receptor from damage brought about by dryness and bacterial infection, and from disuse atrophy via a decrease in transport of taste stimuli to the receptor sites, which is a long-term effect of saliva that may be related to taste disorders.
Iatrogenic Causes of Salivary Gland Dysfunction
Saliva is important for maintaining oral health and function, and there are instances when medical therapy is intended to decrease salivary flow, but most instances of iatrogenic Salivary gland dysfunction represent untoward or unavoidable side-effects.

Human receptors for sweet and umami taste
It is shown that human T1R2/T1R3 recognizes diverse natural and synthetic sweeteners, and this response is enhanced by 5′-ribonucleotides, a hallmark of umami taste, which implicate the T1Rs inUmami taste and suggest that sweet and Umami taste receptors share a common subunit.
