社區的意義包含了兩個社區,一是生產的社區,二是消費群體的社區,兩者之間的距離要近,簽訂以年為單位的契約,讓消費者與生產者共同承擔生產風險。透過小規模、可持續性的生態農業,每個月配「定量、不定種類」的當季新鮮蔬果,保證食材的新鮮、安全,而非一般市場最在乎的農產品長相好壞。2009年的研究《Small Scale Sustainable Farmers Are Cooling Down The Earth》指出,這樣的生態農業生產模式,比起工業化的農作模式,在10年內有望將生產量加倍。
雖然曾有研究透過讓醫師用血液或唾液是否檢測出 IgE 抗體來判斷狗是否過敏(Ermel, R et al.,1997),但最新的研究卻發現,無論使用無論血清的 IgE 抗原或是唾液裡的 IgM 或 IgA 抗原都無法有效檢測出狗狗的過敏來源(Udraite Vovk Let al., 2019 & Lam ATH et al., 2019),甚至會造成偽陽性誤判。因此,目前學界公認唯一能識別食物過敏原的方法就是「食物排除法」(Food Elimination Method)。
