“…The concentration and activity of salivary amylase, an enzyme involved in the initiation of polysaccharide digestion and the modulation of immunity, can be altered by mental health, 14 body composition, diet, 15 and age. 16 The present study has shown that it can also be affected by physical conditioning, even in elderly individuals: EA showed an increase of 130% at the time of exhaustion, with a subsequent reduction thereafter. By contrast, PAE showed a 68% increase in the time to exhaustion with a later peak (T5), reaching an elevation of 100%, and a subsequent sudden reduction.…”

To compare the physical conditioning, hemodynamic, and salivary biomarkers between elderly athletes and the physically active elderly. 14 men: EA (n = 8) and PAE (n = 6). Collection times (T0; TE; T5; T15). A negative correlation was found between SF and cardiovascular parameters, BL, and STP in both groups, but this was almost double among PAE. For HR and SBP, there was a faster recovery in EA. The EA increase was correlated with SBP, while for PAE it was correlated with HR. BL showed an increase in TE, reaching 481% in EA and 639% in PAE. SNO showed a similar increase for the groups at the TE, but at T5, while EA already showed a reduction, PAE saw a 94% increase, with a slower decay for this group at T15. The SF presented the negative delta% was almost double in PAE, with a quick recovery already at T5 for EA and levels still negative at all times for PAE. For SIgA-s, there was an increase of 37% in EA and only 7% at the TE in PAE; 41% in EA and 15% in PAE for T5; and 26% in EA and 14% in PAE at T15. SA showed a higher peak in EA (TE) and less acute in PAE (T5) but there was a decrease among both at T15. STP increased by 126% in EA and 438% in PAE, already showing a return at T5 for EA, but increasing by 213% in PAE. Negative levels were reached at T15 for EA but levels remained high in PAE. Levels of physical conditioning affect cardiovascular parameters, salivary biomarkers, and their correlation within the over-60s.

“…Ben‐Aryeh et al () reported a decline in amylase activity of unstimulated and stimulated parotid saliva with age, while Aguirre, Levine, Cohen, and Tabak () did not find differences in α‐amylase concentration in stimulated parotid saliva of individuals aged 23–84 years. Wang and Woolfolk () investigated age‐related changes in salivary amylase activity between young (<51 years) and elderly (>60 years) Chinese and non‐Chinese Americans. Enzyme activity increased with age in both groups, but this age effect was more pronounced in the Chinese group.…”

“…Even though it is known that perception and preference vary greatly among these consumer groups, differences and similarities in oral physiology, and saliva composition between Westerns and Asians have not yet been described. Wang and Woolfolk () investigated age‐related changes in salivary amylase activity of Chinese and non‐Chinese Americans. The authors observed a more pronounced increase in enzyme activity with age in the Chinese group.…”

Saliva plays an important role in food oral processing. From the breakdown of food structures to the binding of flavor compounds and the formation of a swallowable bolus, saliva is essential for the perception and appreciation of foods. Identifying the factors that affect saliva composition is, therefore, necessary to understand the differences in eating behavior, food perception, and preference across different consumer groups. This article aims to highlight the importance of considering saliva variability when designing food products that meet the needs of specific consumer groups.

“…Furthermore, older non-fed Asian elephants showed higher sAA activity independent from season in contrast to African elephants where age was not correlated with activities of any of the enzymes. Increasing sAA activity with age was already shown in human saliva, which was speculatively caused by age-related histological changes in acinar and ductal cells (Ben-Aryeh et al 1990 ; Wang and Woolfolk 1990 ).…”

Nutritional influences on enzyme activities in saliva of Asian and African elephants

Asian and African elephants show morphological adaptations to their ecological niche including the oral cavity. Variety and preferences of forage plants differ between both herbivorous elephant species. Diet can affect salivary enzymes. Asian elephants were shown to have a higher salivary amylase activity than African elephants. Species-specific differences were presumed to be influenced by feeding during collection procedure. This study aimed to determine the influence of feeding on enzyme activities in saliva of both elephant species to differentiate from species-specific effects. Additionally, season and housing conditions on salivary enzyme activities in non-fed elephants of both species were investigated. Salivary amylase (sAA), lysozyme (sLYS) and peroxidase (sPOD) activity were measured photometrically or fluorometrically. Results of this study reinforce previous observations of higher basic sAA activity in Asian elephants compared to African elephants. Salivary LYS and sPOD activity showed neither species-specific nor housing-specific differences. Independent from season, most elephants of both species revealed a lack of or low sPOD activity. Feeding caused a temporary decrease of sAA, sLYS and sPOD activity in both elephant species kept in four of eight tested zoos. Furthermore, sAA activity in Asian elephants was higher and sLYS activity lower in Spring than in Autumn. This study summarizes that sAA and sLYS are components of Asian and African elephant saliva in an active conformation in contrast to sPOD. Diet varying between season and zoos might influence sAA and sLYS activities primarily in Asian elephants but temporary low effects suggest sufficient buffer capacity of elephant saliva of both species.
