Jessica Chastain has something rarer: a control experiment.<\/p>\n<p>Around 2007, low on energy early in her career, a friend suggested a two-week vegan trial. She did it. Week one: hungry. Week two, <a href=\"https:\/\/www.veganfoodandliving.com\/news\/jessica-chastain-gets-sick-drops-plant-based-diet\/\">in her own words<\/a>: &ldquo;I felt amazing.&rdquo; Then came the scientific part: after the two weeks she went to a restaurant, ordered fish and risotto, and promptly felt sick again. Test, result, conclusion.

As recently as 2024 she said eating animal products makes her feel sick, and credits the diet for the energy to shoot four movies a year.<\/p>\n<p class=\"tiv-check\">Last fact-checked: July 7, 2026<\/p>\n<\/div>\n<h2>The reluctant vegan<\/h2>\n<p>Here&rsquo;s what makes Chastain&rsquo;s story credible: she never wanted this. &ldquo;Being vegan was not anything I ever wanted to be,&rdquo; <a href=\"https:\/\/www.cheatsheet.com\/news\/jessica-chastain-went-vegan-on-a-whim-im-going-to-just-listen-to-my-body-now.html\/\">she&rsquo;s said<\/a>. &ldquo;I just really was listening to what my body was telling me.&rdquo; No ideology, no campaign, just a body that ran better on plants, more energy &ldquo;than I&rsquo;ve ever had in my life&rdquo;, and a stubborn cholesterol problem that finally resolved.<\/p>\n<p>The result speaks in filmography. The Help, Zero Dark Thirty, her Oscar for The Eyes of Tammy Faye, all of it powered by plants. In her 2024 Radio Times interview she connected the dots herself: &ldquo;Now, I have so much energy and I do four movies a year.&rdquo;<\/p>\n<h2>The vegan timeline, tap to expand<\/h2>\n<details class=\"tiv-tl\">\n<summary>Around 2007: the two-week experiment<\/summary>\n<div class=\"tiv-tlb\">A friend suggests a vegan trial.

Aus S\u00fcddeutschland, besser gesagt aus dem Schwarzwald, seit 2019 Gr\u00fcnder von This Is Vegan, mittlerweile in Bali zuhause. Von hier aus treibe ich Tierschutzprojekte voran und reise um die Welt. Vegetarier bin ich seit dem 6. Lebensjahr, vegan seit \u00fcber 20 Jahren. Mein Ansatz war nie, Leuten ein schlechtes Gewissen zu machen. Sondern zu zeigen, wie einfach, lecker und entspannt vegan im Alltag funktioniert. Anziehung statt Ablehnung. Genau daf\u00fcr gibt's dieses Online-Magazin und den Plantbased Podcast: Menschen inspirieren, sich f\u00fcr Tiere und Umwelt stark zu machen und vegan zu leben.","sameAs":["https:\/\/www.this-is-vegan.com","https:\/\/www.instagram.com\/yannick.haldenwanger\/","https:\/\/www.linkedin.com\/in\/yannickhaldenwanger\/","https:\/\/www.pinterest.de\/thisisvegan_magazin\/","https:\/\/www.youtube.com\/@thisisvegan"],"knowsAbout":["vegane Ern\u00e4hrung","holistische Gesundheit","Ern\u00e4hrung","vegane Rezepte","Kampfsport","Kraftsport","Proteine"],"knowsLanguage":["deutsch","englisch","franz\u00f6sisch","indonesisch"],"jobTitle":"Gr\u00fcnder","url":"https:\/\/this-is-vegan.com\/en\/author\/yannick\/"}]}},"_links":{"self":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts\/40578","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/comments?post=40578"}],"version-history":[{"count":1,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts\/40578\/revisions"}],"predecessor-version":[{"id":40603,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts\/40578\/revisions\/40603"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/media\/40634"}],"wp:attachment":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/media?parent=40578"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/categories?post=40578"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/tags?post=40578"},{"taxonomy":"ernaehrungsform","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/ernaehrungsform?post=40578"},{"taxonomy":"schwierigkeit","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/schwierigkeit?post=40578"},{"taxonomy":"schaerfe","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/schaerfe?post=40578"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
