“…However, the sour bolus is the most difficult bolus taste to recognize by patients with stroke 3 . Among the patients included in this investigation, the identification of bitter and sour bolus tastes had a less frequent identification than sweet and neutral bolus tastes 22 . It is not clear if the alteration of EMG activity with the sour bolus is dependent on the perception of taste.…”

Objective. To evaluate the effect of different bolus flavors in oral and pharyngeal transit duration of patients with stroke and normal volunteers. Method. The investigation had the participation of 36 patients (44-82 years, mean age: 63 years) with occurrence of stroke from 1 month to 84 months (median: 5.5 months) and 30 normal subjects (33-85 years, mean age: 59 years) who comprised the control group. The scintigraphic method was used to evaluate the oral and pharyngeal transit. Each subject swallowed in random sequence 5 mL of a liquid bolus of bitter, sour, sweet, and neutral taste, all labeled with 37 MBq of 99m Technetium coupled with phytate. Results. Oral transit was longer in patients with stroke than in the control subjects for the sweet, bitter and sour tastes. Pharyngeal transit and clearance was longer in patients with stroke for the sweet and bitter tastes. In both groups there were no differences between neutral, sweet, sour or bitter tastes. Conclusion. Bolus tastes evaluated did not change oral and pharyngeal transit in normal subjects and patients with stroke.

Avaliar o efeito do sabor na duração do trânsito oral e faringeano de pacientes com Acidente Vascular Cerebral (AVC) e voluntários normais. Método. Participaram da investigação 36 pacientes com AVC (44-82 anos, média: 63 anos), ocorrido de 1 mês a 84 meses (mediana: 5,5 meses), e 30 voluntários controles (33-85 anos, média: 59 anos). Foi utilizado a cintilografia para avaliar os trânsitos oral e faringeo. Em sequência aleatória foi ingerido 5 mL de bolo líquido de sabores amargo, azedo, doce e neutro, com 37 MBq de 99m Tecnécio ligado a fitato. Resultados. O trânsito oral foi maior em pacientes com AVC do que nos indivíduos controles, para os sabores doce, amargo e azedo. O trânsito faríngeo e a depuração foram mais longos em pacientes com AVC para os gostos doce e amargo. Em ambos os grupos não houve diferença entre os sabores neutro, doce, azedo e amargo. Conclusão. O gosto dos bolos deglutidos testados não alteraram os trânsitos oral e faríngeo de indivíduos normais e de pacientes com AVC.

“…For example, a study comparing 36 patients with stroke and 30 control subjects reported that the stroke group had difficulty in the perception of bitterness and sourness [36]. Similarly, patients with Parkinson's and other cortical neurodegenerative diseases showed a decrease of olfactory and gustatory function compared to healthy subjects [37,38].…”

Background: Bitterness perception seems to be related to an enhanced intake of dietary fat and to a tendency to the development of diseases such as obesity. However, the exact factors for this possible contribution still need to be better investigated. So, gustatory perception of the bitter taste is a promising area of study because of its importance regarding food choices and consequently feeding behavior. Therefore, this short review focused on recent papers reporting correlations between bitter taste, anthropometric variables, obesity and other chronic diseases, age, gender, ethnicity, and genetics. Methods: A survey was performed in MEDLINE (PubMed) and Scielo from September 2015 to January 2017. Only review articles, observational studies and clinical trials published in English and Portuguese over the last 15 years which met the objectives of the present study were considered. A total of 40 papers were evaluated. Results: Two papers showed a positive correlation between bitter taste and obesity, one indicated that this correlation is influenced by the subject's age, one suggested a negative correlation, and two found no association. Age seems to be negatively correlated with the bitterness perceived, and female gender was associated with a stronger perception of bitterness. Genetics, mostly due to differences in TAS2R38 expression, influences sensitivity to the bitter taste, feeding behavior and also alcohol intake. Ethnicity, not only the subject's phenotypic or genotypic characteristics, seems to play a role in taste perception and nutritional diseases. Conclusions: Age, gender, genetics and ethnicity seem to play a role in bitterness perception. Data about associations between bitterness perception and anthropometrics are conflicting.
