A new study has found that by adding a little spicy seasoning to a low sodium meal, adults over the age of 60 will have a harder time noticing the lack of salt.The study has been published in the 'Food Quality and Preference Journal'.Led by Carolyn Ross, a professor of Food Sciences at Washington State University, the study tested saltiness perception in older adults using white sauce formulations with varying amounts of salt and different spices and seasonings added.The results of the analysis showed the addition of chipotle seasoning to the white sauce made it difficult for the study participants to differentiate between the samples with low and high levels of salt. Conversely, the addition of herbs, such as basil leaves, garlic powder and coarse ground pepper, was not as effective at masking the samples with less salt. The research pointed to the significant role that spice could play in reducing salt intake for people over 60."We were working specifically with a population of older adults to see if we could reduce the amount of salt in a product and then tailor it to their tastes," Ross said."This is important because the ability to taste and smell is known to weaken with age, and weaker perception of salty flavours may induce people to season their food with excessive salt, which may increase their risk of cardiovascular disease," Ross added.For their study, Ross and Maria Laura Montero, a postdoctoral researcher in the WSU School of Food Sciences, recruited 39 healthy people over the age of 60 to participate in an in-person taste-testing experiment that took place over several days slightly prior to the onset of the COVID-19 pandemic.Previous research examining saltiness perception in older adults has tended to use water as a matrix for tasting experiments rather than actual food products. To generate more realistic data in terms of what people actually enjoy eating, Ross and Montero used a white sauce formulation that is commonly found in ready-to-eat Cajun chicken pasta meals.The study participants were asked to compare three different formulations of the sauce at five different salt concentrations. One of the formulations had no added herbs, the second had just herbs, and the third had both herbs and chipotle seasoning. Their results showed the formulation with both herbs and chipotle seasoning made it difficult for the seniors to determine the amount of salt being used while the formulation with exclusively herbs did not.In addition to administering the taste test, the researchers surveyed their participants about their oral and olfactory health, the number and type of medications they were taking and any other pre-existing conditions that might affect their saltiness perception.Their analysis showed there was a positive correlation between poor oral health and the number of medications each participant was taking, which could be a result of less saliva production; however, their data on whether or not this was the main cause of lowered saltiness perception wasn't conclusive.Moving forward, when it is once again feasible to recruit participants for in-person studies, the researchers plan to follow up with a larger study evaluating lower salt concentrations as well as different herb and spice concentrations."To date, a clear relationship between taste loss, and thus higher taste thresholds, and eating behaviour remains to be established," Ross said."So, we are investigating a bunch of different possible factors," Ross added.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
