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.

Act\u00faa como antioxidante y protege los gl\u00f3bulos rojos y las c\u00e9lulas frente a da\u00f1os. Tambi\u00e9n es importante para que la tiroides funcione bien. Adem\u00e1s, el selenio hace menos t\u00f3xicos los metales pesados que a veces llegan a los alimentos.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El selenio est\u00e1 presente en muchos alimentos, sobre todo en el pescado y en algunos tipos de frutos secos. En los productos de origen vegetal, la cantidad depende de cu\u00e1nto selenio haya en el suelo. En los Pa\u00edses Bajos, normalmente no se ve una carencia. Aun as\u00ed, las personas que comen sobre todo productos vegetales o ecol\u00f3gicos tienen m\u00e1s probabilidades de tener una ingesta demasiado baja.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La falta de selenio puede ir acompa\u00f1ada de problemas de coraz\u00f3n, dolor muscular y debilidad muscular. Con la comida no es f\u00e1cil tomar demasiado selenio, pero con suplementos s\u00ed puede pasar. Tomar demasiado selenio durante mucho tiempo puede provocar p\u00e9rdida de pelo, u\u00f1as y dientes, da\u00f1os en la piel y trastornos del sistema nervioso.<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\">Por qu\u00e9 importa el selenio<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Con el selenio cuentan tanto una ingesta demasiado baja como una demasiado alta.

Si tomas menos que la ingesta adecuada, seg\u00fan el Voedingscentrum eso no significa directamente que tengas una carencia. Aun as\u00ed, las ingestas bajas se asocian a un mayor riesgo de enfermedades del coraz\u00f3n y de los vasos sangu\u00edneos. No se sabe si en los Pa\u00edses Bajos se da una ingesta demasiado baja, ni con qu\u00e9 frecuencia.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Selenio demasiado alto<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Tomar demasiado selenio durante mucho tiempo puede ser perjudicial para tu salud. Por eso la EFSA ha fijado un l\u00edmite superior tolerable. Ese l\u00edmite incluye un margen de seguridad.
