Caught by LOOKING at the live page on 2026-07-30, right after\n   the template was switched to canvas.\n\n   Everything is scoped to `.bp-adv`, so nothing here can reach the rest of\n   bioprofile.com, and core blocks are styled BY ELEMENT so a heading, a\n   paragraph, a quote, a list, an image or a button inserted by hand inside the\n   advertorial comes out on-design with no class to remember.\n\n   Jesse's design feedback, 2026-07-29 23:38, point by point:\n   1. the light green and the dark green are the preferred colours; grey may be\n      used but the page must NOT open grey;\n   2. more colour and variation across sections, e.g. a colour block on the left\n      or the right side of a section, without overdesign;\n   3. ONE H1, plain text on white; everything else H2 or H3; an H2 may carry its\n      own background colour so the page can be read from the headings alone; an\n      H3 keeps its section background and gets a bigger font size;\n   4. reuse the results page design feel;\n   5. Written by \/ Verified by, the placeholder blocks and noindex stay.\n\n   COLOUR PROVENANCE. Not one hex is invented.\n   - #b7cb32  LIGHT GREEN, brand manual \"colours rejuvenation protocol\"\n              (R183 G203 B51). Same value as --bp-lime in\n              brands\/bioprofile\/brand\/tokens.md.\n   - #006b62  DARK GREEN, brand manual, nourish the cells (R0 G107 B98).\n   - #005859  brand manual primary teal, the value the brand is built on.\n   - #228a62  brand manual, challenge the body (R34 G138 B98).\n   - #7ca64c  brand manual, calm the mind (R124 G166 B76).\n   - #dbd4cd  brand manual \"additional color\", the warm neutral.\n   - #B7CB3329 is the brand token --bp-lime-soft (light green at 16 percent).\n   - the gradients are the brand token layer's own, copied verbatim.\n\n   SPECIFICITY NOTE. Elementor's global kit emits `.elementor-kit-6 h2` style\n   rules at (0,1,1). Element rules below are written `.bp-adv h2`, also (0,1,1),\n   and win on source order because this sheet is inline in the body while the\n   kit is a <link> in the head. Component rules that MUST NOT lose carry two\n   classes, e.g. `.bp-adv .wp-block-button__link`.\n\n   LAYOUT NOTE. Vertical rhythm uses `margin-block` and never the `margin`\n   shorthand, so the measure rule `.bp-adv-sec > * { margin-inline: auto }` can\n   centre a block without being outranked by its own element rule.\n   =========================================================================== *\/\n\n.bp-adv {\n  --bp-ink: #212527;\n  --bp-teal: #005859;\n  --bp-forest: #006B62;\n  --bp-emerald: #228A62;\n  --bp-olive: #7CA64C;\n  --bp-lime: #B7CB33;\n  --bp-lime-soft: #B7CB3329;\n  --bp-sand: #DBD4CB;\n  --bp-white: #FFFFFF;\n  --bp-foot: #6b6b6b;\n  --bp-grad-dark: linear-gradient(237deg, rgba(0,88,89,0.00) 62.94%, #005859 100%), linear-gradient(90deg, rgba(34,138,98,0.00) 40%, #228A62 100%), #006B62;\n  --bp-grad-lime: linear-gradient(110deg, rgba(183,203,51,0.00) 36.06%, rgba(183,203,51,0.25) 97.65%), #FFFFFF;\n  --bp-font: 'Poppins','Segoe UI',Arial,sans-serif;\n  --bp-fs-h1: 44px; --bp-fs-h2: 31px; --bp-fs-h3: 24px; --bp-fs-pre: 15px;\n  --bp-fs-body: 17px; --bp-fs-small: 14px; --bp-fs-foot: 13px; --bp-fs-btn: 17px;\n  --bp-lh-body: 1.75;\n  --bp-s-1: 4px; --bp-s-2: 8px; --bp-s-3: 12px; --bp-s-4: 16px;\n  --bp-s-5: 24px; --bp-s-6: 32px; --bp-s-7: 44px; --bp-s-8: 72px;\n  --bp-measure: 760px; --bp-side: 40px;\n  --bp-radius-photo: 16px; --bp-radius-btn: 10px; --bp-radius-card: 20px;\n  --bp-shadow: 0 10px 30px rgba(0,88,89,0.10);\n  font-family: var(--bp-font);\n  font-size: var(--bp-fs-body);\n  line-height: var(--bp-lh-body);\n  color: var(--bp-ink);\n  background: var(--bp-white);\n  -webkit-font-smoothing: antialiased;\n}\n.bp-adv, .bp-adv * { box-sizing: border-box; }\n.bp-adv p, .bp-adv li, .bp-adv h1, .bp-adv h2, .bp-adv h3, .bp-adv blockquote,\n.bp-adv a, .bp-adv cite, .bp-adv span { overflow-wrap: break-word; min-width: 0; }\n\n\/* THE TOGGLE.

Es wirkt als Antioxidans und sch\u00fctzt rote Blutk\u00f6rperchen und Zellen vor Sch\u00e4den. Au\u00dferdem ist es wichtig f\u00fcr eine gute Funktion der Schilddr\u00fcse. Dar\u00fcber hinaus macht Selen Schwermetalle, die manchmal in die Nahrung gelangen, weniger giftig.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Selen steckt in vielen Lebensmitteln, vor allem in Fisch und bestimmten Nusssorten. Bei pflanzlichen Lebensmitteln h\u00e4ngt die Menge davon ab, wie viel Selen im Boden enthalten ist. In den Niederlanden kommt ein Mangel normalerweise nicht vor. Menschen, die sich \u00fcberwiegend pflanzlich oder biologisch ern\u00e4hren, haben jedoch ein h\u00f6heres Risiko f\u00fcr eine zu geringe Zufuhr.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ein Mangel an Selen kann mit Beschwerden am Herzen, Muskelschmerzen und Muskelschw\u00e4che einhergehen. \u00dcber die Nahrung nehmen Sie nicht so leicht zu viel Selen auf, mit Nahrungserg\u00e4nzungsmitteln ist das aber m\u00f6glich. \u00dcber lange Zeit zu viel Selen kann zum Verlust von Haaren, N\u00e4geln und Z\u00e4hnen, zu Sch\u00e4den an der Haut und zu Erkrankungen des Nervensystems f\u00fchren.<sup>[1]<\/sup><\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-adv-sec is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\" id=\"bp-waarom-het-ertoe-doet\">Warum Selen wichtig ist<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Bei Selen z\u00e4hlen sowohl eine zu niedrige als auch eine zu hohe Zufuhr. Das Voedingscentrum nennt deshalb f\u00fcr beide Seiten eine Grenze: eine angemessene Zufuhr und eine tolerierbare Obergrenze.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Paran\u00fcsse enthalten so viel Selen, dass eine Handvoll schon \u00fcber der tolerierbaren Obergrenze liegt. Deshalb empfiehlt das Voedingscentrum, mit anderen ungesalzenen N\u00fcssen abzuwechseln, zum Beispiel mit einer Handvoll ungesalzener gemischter N\u00fcsse.<sup>[1]<\/sup><\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-adv-sec bp-adv-sec--wash is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\" id=\"bp-wat-je-waarde-zegt\">Was Ihr Selenwert aussagt<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Die Richtlinie des Labors<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Labplusarts, das Labor, mit dem BioProfile arbeitet, verwendet f\u00fcr Selen einen Referenzwert von 0,64 bis 1,91 umol\/l.

Dies sind Mengen an Selen pro Tag aus Ihrer Ern\u00e4hrung, keine Blutwerte. Die tolerierbare Obergrenze wurde von der Europ\u00e4ischen Beh\u00f6rde f\u00fcr Lebensmittelsicherheit (EFSA) festgelegt.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Selen zu niedrig<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Das Voedingscentrum nennt Grenzen f\u00fcr die Zufuhr, nicht f\u00fcr Ihren Blutwert. Nehmen Sie weniger auf als die angemessene Zufuhr, haben Sie laut dem Voedingscentrum nicht gleich einen Mangel. Eine niedrige Zufuhr h\u00e4ngt jedoch mit einem h\u00f6heren Risiko f\u00fcr Erkrankungen von Herz und Blutgef\u00e4\u00dfen zusammen. Ob und wie oft eine zu niedrige Zufuhr in den Niederlanden vorkommt, ist nicht bekannt.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Selen zu hoch<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u00dcber lange Zeit zu viel Selen aufzunehmen kann Ihrer Gesundheit schaden. Deshalb hat die EFSA eine tolerierbare Obergrenze festgelegt. Diese Grenze ber\u00fccksichtigt eine Sicherheitsspanne. \u00dcberschreiten Sie sie einmal, bekommen Sie nicht sofort Beschwerden.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BioProfile arbeitet an eigenen Zonen pro Wert, von Risiko bis optimal.

In Vollkornprodukten und Gem\u00fcse h\u00e4ngt die Menge vom Selengehalt des Bodens ab. Paran\u00fcsse enthalten viel Selen.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Nahrungserg\u00e4nzungsmittel<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u00dcber die Ern\u00e4hrung nehmen Sie nicht so leicht zu viel Selen auf.
