The combination of nutrition education at school and home visits to improve adolescents' nutritional literacy and diet quality in food-insecure households in post-disaster area (De-Nulit study): A study protocol of cluster randomized controlled trial (CRCT).

Nutrition education is selected as a method which often used to change eating behaviour, yet, the effectiveness of this method in adolescents who live in household with food insecurity status is rarely investigated. The purpose of this study was to assess the impact of a combination of nutritional education held at school and home visits for increasing the nutritional literacy and its effect on the quality of adolescent diet, so that the result can be used as a strategy to improve nutritional literacy dan diet quality in those adolescents who live in food-insecure households in post-disaster areas. The De-Nulit Study is a Cluster Randomized Controlled Trial (CRCT) with an intervention from a combination of nutritional education given at school and home visits conducted for three months for adolescents who live in food-insecure households with ages ranging from 15 to 17 years old. A randomization sampling was carried out at four schools located the nearest locations which were affected heavily by the major natural disasters in 2018. The nutritional education intervention groups in schools were given in eight sessions, whereas home visits with an interview approach for students with a motivational interview approach were carried out four times. The control group will receive leaflets three times a month for three months, and each group will receive a food stamp $ 7.6 per month for three months. The trial research has been recorded in Thai Clinical Trials Registry (TCTR) with identification number of TCTR 20220203003 issued on 03 February 2022.

Antioxidant properties of the methanolic extract of avocado fruit peel (Persea americana Mill.) from Indonesia.

This study analyzed the antioxidant activity and the phytochemical substances in avocado fruit peel extracted with methanol. In this study, antioxidant activity was determined by IC50 based on the regression value of DPPH free radicals' inhibition. Phytochemical content was measured qualitatively concerning the total content of phenols, flavonoids, tannins, saponins, and alkaloids. Our measurements showed that the methanolic extract of avocado fruit peels from Indonesia had the value of each phytochemical compound as follows: total phenol was 21.833 ± 0.118 mg/100 g extract; total flavonoids were 2.607 ± 0.111 mg/100 g extract; total tannin was 38.357 ± 0.202; saponin content was 8.874% ± 0.031%; and total alkaloid was 9.95 ± 0.035 mg CE/g extract. They then provided the antioxidant activity in IC50, which reached 185.891 ± 1.598 ppm. Avocado fruit peels are identified as a phytochemical source that contributes to antioxidant activities.
