Abstract |
: |
Poor memory and attention are common problems around the world. Recently, many dietary components of food have been identified as having positive effects on cognitive improvement. One of the drinks that improves memory and attention is Japanese Matcha tea. This study aimed to investigate the effect of Matcha supplement consumption on cognitive performance in female adults aged 19–35 years in Saudi Arabia in three phases. First, the knowledge and awareness of Matcha tea and its health benefits were assessed using a questionnaire consisting of 20 questions divided into three parts: sociodemographic characteristics, awareness of health benefits, and Matcha consumption. The questionnaire was completed by 333 participants. Second, the effect of Matcha supplementation on attention and memory was evaluated 1 hour after consumption. The study was conducted on 50 participants who were randomly divided into two groups, with each group consisting of 25 participants. The duration of the experiment was 24 hours. The participants were asked to sleep for at least 8 hours, refrain from eating and drinking for 12 hours, and to stop consuming caffeine 24 hours before the experiment. The control group did not receive any placebo and were allowed to drink water before taking the Woodcock–Johnson Cognitive Test (WJCT), and they took the WJCT within 30–35 minutes. The experimental group took the WJCT 1 hour after consumption of six supplement equivalents (3 g) of Matcha with 1–2 cups of water. Finally, a new pudding-based product was developed containing 3 g of Matcha to increase the consumption of Matcha. The chemical and physical properties of the pudding were analyzed, and sensory evaluation was conducted. The results indicated that most participants were unaware of the health benefits of Matcha and did not consume Matcha in their diets. In addition, the results showed that the group who received the Matcha supplement had significantly higher letter-pattern matching, verbal attention, and cognitive efficiency scores compared with the control group. In addition, the total fat content was higher in the Matcha pudding than in the control pudding, the spread line decreased after 24 hours of refrigeration, and most participants preferred the control pudding over the Matcha pudding, which might be related to consumer preferences in terms of the taste and flavor of the pudding. The findings indicated that increased awareness of the benefits of Matcha would result in increased consumption of Matcha. Consuming Matcha supplement improved the participants’ cognitive performance by increasing attention and memory; therefore, consuming the recommended dose of Matcha supplement improves cognitive performance. |
