加工食品を多く食べる習慣がある人は，うつ病の危険性が高いことが新たな研究で明らかになった。食事全体とうつ病の関連性についての研究はこれが初めてだ。ロンドン在住の約3,500人の大人を対象に質問票を使って調査したところ，加工していない野菜や果物，魚を多く食べる人ほど抑うつ症状が少なく，加工した肉類，甘いデザート，揚げ物，高脂肪の乳製品などを多く食べる人にはこのような症状が多かった。研究者らは，野菜や果物に含まれる抗酸化物質や，一部の野菜に含まれる葉酸の効果が関連していると考えている。（吉田素子）
People who eat a diet laden with(1) processed(2) and high-fat(3) foods may put themselves at greater risk of(4) depression(5), according to(6) UCL(7) research published today.
The research team, led by Dr Tasnime Akbaraly (UCL Epidemiology(8) and Public Health(9)), also found that eating a ‘whole food(10)’ diet with plenty of(11) fresh vegetables, fruit and fish could help prevent the onset(12) of depressive symptoms(13) in middle age.
The study, published in the November issue of British Journal of Psychiatry(14), is the first to examine the association between overall diet and depression – previous studies have focused on(15) the effect of individual nutrients(16).
Researchers(17) from UCL studied 3,486 people with an average age of 55, and who worked in civil service departments(18) in London. Each participant(19) completed a questionnaire(20) about their eating habits(21), and a self-report(22) assessment(23) for depression.
The researchers found that people with the highest intake of(24) ‘whole food’ were less likely to(25) report having symptoms of depression. In contrast(26), high consumption of(27) processed food was associated with increased odds(28) of depression.
These associations between diet and onset of depressive symptoms remained after the researchers controlled for(29) other indicators(30) of a healthy lifestyle, such as not smoking, taking physical activity(31) and a healthy body mass(32).
The authors said: “Our results suggest that consuming(33) fruits, vegetables and fish may afford protection against(34) the onset of depressive symptoms, whereas a diet rich in(35) processed meat, chocolates, sweetened(36) desserts, fried food, refined(37) cereals(38) and high-fat dairy products(39) would increase people’s vulnerability(40).”
