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.

HbA1c tells you something about your blood sugar over a longer period. With this conversion, you see that value in the same unit as an ordinary blood sugar measurement, such as millimoles per litre.<sup>[1, 2]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This value is not measured separately, but calculated from your HbA1c. HbA1c is the part of your haemoglobin that has sugar attached to it. Researchers compared HbA1c with the average blood sugar over the three months before and found a fixed formula. That formula did not clearly differ by age, sex or smoking.<sup>[1, 2]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In children and young people too, researchers found a direct relationship between HbA1c and average blood sugar. There, blood sugar was measured with a sensor over several days in a row. This means average blood sugar can easily be calculated from HbA1c.<sup>[1, 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 this value counts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you track your blood sugar every day, you often measure it yourself with a finger prick. That result is given in milligrams per decilitre or millimoles per litre. HbA1c comes as a percentage. Estimated average glucose makes it easy to put those two side by side.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the study, each participant's blood sugar was measured thousands of times, with sensors and finger pricks, spread over 3 months. This means the formula is based on a good picture of true average blood sugar.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The researchers concluded that for most people with a condition affecting blood sugar regulation, HbA1c can be expressed as estimated average glucose.<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\">What your estimated average glucose value tells you<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What the research by Nathan and colleagues shows<\/h3>\n\n\n\n<figure class=\"wp-block-table bp-bm-table\"><table><thead><tr><th>Level<\/th><th>Can point to<\/th><th>Who it is for<\/th><\/tr><\/thead><tbody><tr><td>Higher HbA1c<sup>[1]<\/sup><\/td><td>a higher average blood sugar over the previous 3 months<\/td><td>people in the study, with and without a condition affecting blood sugar regulation<\/td><\/tr><tr><td>Lower HbA1c<sup>[1]<\/sup><\/td><td>a lower average blood sugar over the previous 3 months<\/td><td>people in the study, with and without a condition affecting blood sugar regulation<\/td><\/tr><tr><td>Formula: AG (mg\/dl) = 28.7 x A1C - 46.7<sup>[1]<\/sup><\/td><td>the estimated average glucose at a given HbA1c value<\/td><td>the same regardless of age, sex, type of condition, ancestry and smoking habits<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"bp-bm-caption wp-block-paragraph\">Source: Nathan et al., 2008, a study of 507 people from 10 centres.
