“…In this study, the diet quality score was positively associated with the intakes of specific dietary components whose higher intakes were previously suggested to lower the risk of depressive symptoms. These include dairy products ( 35 , 61 ) , fruit ( 10 , 11 ) , seaweed ( 26 ) , soya products ( 27 ) , vegetables ( 10 , 11 ) , EPA+DHA ( 6 , 7 ) , dietary fibre ( 34 ) , Ca ( 35 ) , Mg ( 36 , 37 ) , Fe ( 38 ) , folate ( 4 , 5 ) and vitamin C ( 39 ) . The score was also inversely associated with intakes of confectioneries and sugar (as a source of added sugar) ( 34 ) , soft drinks ( 62 , 63 ) and total and saturated fats ( 8 ) , and higher intakes of these foods and nutrients have been suggested to increase the risk.…”

“…The diets consumed by Japanese are typically characterised by high intakes of rice, soya products, fish, seaweeds and green tea and low intakes of animal fat and soft drinks ( 25 ) . Actually, previous Japanese studies have shown inverse associations of intakes of fish ( 8 ) , seaweed ( 26 ) , soya products ( 27 ) and green tea ( 28 , 29 ) with the prevalence of depressive symptoms. To our knowledge, however, only a few studies have focused on the association between dietary patterns and depressive symptoms in Japanese ( 30 – 32 ) .…”

Only a few studies have focused on the association between overall diet, rather than intakes of individual nutrients or foods, and depressive symptoms in Japanese. This cross-sectional study examined associations between a diet quality score and depressive symptoms in 3963 young (age 18 years) and 3833 middle-aged (mean age 47·9 (sd 4·2) years) Japanese women. Dietary information was collected using a diet history questionnaire. A previously developed diet quality score was computed mainly based on the Japanese Food Guide Spinning Top. The prevalence of depressive symptoms was 22·0 % for young women and 16·8 % for middle-aged women, assessed as a Center for Epidemiologic Studies Depression (CES-D) score ≥23 and ≥19, respectively. As expected, the diet quality score was associated positively with intakes of 'grain dishes', 'vegetable dishes', 'fish and meat dishes', 'milk' and 'fruits' and inversely with intakes of energy from 'snacks, confection and beverages' and Na from seasonings. After adjustment for potential confounders, OR for depressive symptoms in the highest v. lowest quintiles of the diet quality score was 0·65 (95 % CI 0·50, 0·84) in young women (P for trend=0·0005). In middle-aged women, the corresponding value was 0·59 (95 % CI 0·45, 0·78) (P for trend<0·0001). Analyses where the diet quality and CES-D scores were treated as continuous variables also showed inverse associations. In conclusion, this cross-sectional study showed that a higher diet quality score was associated with a lower prevalence of depressive symptoms in young and middle-aged Japanese women. Prospective studies are needed to confirm a public health relevance of this finding.

Persimmon Fruit Powder May Substitute Indolbi, a Synthetic Growth Regulator, in Soybean Sprout Cultivation

et al. 2017

Soybean sprouts are a major food item in Korea. Various studies have been carried out to enhance their yield and nutritional values. The objective of the present study was to examine the influence of persimmon fruit powder and Indolbi, a synthetic plant growth regulator, on the yield and nutritional value of soybean sprouts. Seeds were soaked in tap water containing 0.5%, 1.0%, 2.5% and 5.0% (w/v) persimmon fruit powder and the samples were named as PT-1, PT-2, PT-3, and PT-4, respectively. The yield increment was almost doubled in PT-3 and PT-4 than in the Indolbi treated sprouts on basis of the control. Vitamin C, isoflavones, and total phenolic contents as well as antioxidant potentials (determined by 1,1-diphenyl-2-picrylhydrazyl and superoxide anion radical scavenging assays) were also significantly (p < 0.05) higher in PT-3 compared to the Indolbi treatment and the control. However, total free amino acid and magnesium contents of Indolbi- applied sprouts were higher than in the fruit powder treatments. The overall results of the present study showed that persimmon fruit powder can be an option to enhance the yield and nutritional value of soybean sprouts since, due to potential health hazards, the use of synthetic chemicals like Indolbi is less preferred than the natural products.

“…Dear Editor, In a recent paper by Miyake et al, the researchers studied the association between soy isoflavone intake and the prevalence of depressive symptoms in 1745 pregnant Japanese women [1]. They concluded that higher intake of soy products was associated with lower prevalence of depressive symptoms during pregnancy.…”
