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.

It is found in low amounts in rock, soil and groundwater. There are organic and inorganic forms. The inorganic forms are more harmful to your health.<sup>[2]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Arsenic is a natural part of the earth's crust. You find it everywhere in the environment: in the air, in water and in the soil.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Arsenic mainly ends up in food through pollution of the environment. Plants take it up from the soil and water. Animals take it in through water and feed.<sup>[2]<\/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\">Why arsenic matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you take in a lot of inorganic arsenic through drinking water and food over a long time, you can develop long-term arsenic poisoning. The first signs usually show on the skin: a change in skin colour, patches on the skin and hard patches on the palms of the hands and the soles of the feet. This happens after about five years or longer.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the WHO, taking in too much arsenic over a long time may also be linked to serious conditions of the bladder, lungs and heart, to a disorder of blood sugar and to effects on development.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Arsenic is also linked to poorer outcomes if you are pregnant and to effects on children's health. Studies show harmful effects on the development of thinking, on intelligence and on memory.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is no tolerable daily intake for arsenic. That is why food should contain as little arsenic as possible. The European Union has set strict maximum levels, and for rice products for young children these are even lower.<sup>[2]<\/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\">What your arsenic (urine) level tells you<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What the WHO describes<\/h3>\n\n\n\n<figure class=\"wp-block-table bp-bm-table\"><table><thead><tr><th>Exposure according to the WHO<\/th><th>Can point to<\/th><th>Who it is for<\/th><\/tr><\/thead><tbody><tr><td>A lot of arsenic in a short time<sup>[1]<\/sup><\/td><td>Vomiting, stomach pain and diarrhoea, followed by numbness and tingling in the hands and feet, and muscle cramps<\/td><td>People with acute arsenic poisoning<\/td><\/tr><tr><td>A lot of inorganic arsenic over a long period<sup>[1]<\/sup><\/td><td>Changes in skin colour, patches on the skin and hard patches on the palms of the hands and soles of the feet<\/td><td>People who take in arsenic through drinking water and food over a long period<\/td><\/tr><tr><td>Arsenic before birth and in early childhood<sup>[1]<\/sup><\/td><td>Effects on the child's health and development<\/td><td>Pregnant women and young children<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"bp-bm-caption wp-block-paragraph\">Source: WHO, fact sheet on arsenic.

The WHO does say that people take in more inorganic arsenic through contaminated drinking water, food prepared or grown with such water, industrial processes and smoking. A higher value may point to more exposure to arsenic.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BioProfile is working on its own zones for each value, from risk to optimal.

The Voedingscentrum advises you to vary with other grain products and potatoes, and not to give children rice or rice cakes every day. If you wash rice and cook it in plenty of water, you rinse away some of the arsenic.<sup>[2]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fish and seafood<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fish, shellfish, meat, poultry, dairy and grains can also contain arsenic, but usually much less than contaminated groundwater. In seafood, arsenic is mostly found in the less toxic organic form.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Drinking water<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">According to the WHO, contaminated groundwater is the biggest source. In countries including Bangladesh, India, China and the United States, groundwater naturally contains a lot of inorganic arsenic.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Smoking and work<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Tobacco plants take up arsenic from the soil, so if you smoke, you also take in arsenic. Arsenic is also used in making glass, pigments, textiles, paper and wood preservatives, in tanning hides and, to a limited extent, in pesticides, animal feed and medicines.<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-welke-pakketten\">Which BioProfile packages measure arsenic (urine)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Arsenic in urine is not part of any of the five packages.
