The Claim

African-American women have lower levels of apoCIII in very low-density lipoproteins (VLDL) and total apoB-containing lipoproteins than white women after adjustment for insulin sensitivity, despite higher insulin resistance, indicating race-specific regulation of apoCIII production or clearance that is not fully explained by metabolic factors.

How it works
1 study reviewed
In plain English

African-American women have lower levels of apoCIII in certain blood lipoproteins than white women, even though they have higher insulin resistance, suggesting biological differences in how apoCIII is produced or cleared that are not due to metabolic factors.

See the scientific wording

African-American women have lower levels of apoCIII in very low-density lipoproteins (VLDL) and total apoB-containing lipoproteins than white women after adjusting for insulin sensitivity, despite greater insulin resistance, suggesting race-specific regulation of apoCIII production or clearance that is not fully explained by metabolic factors.

Why this might work

African-American women produce less apoCIII protein in the liver because they have genetic variants that lower the activity of the apoCIII gene, and their lower visceral fat reduces signals that would otherwise increase apoCIII production. Even though their bodies are more resistant to insulin, this genetic and fat-related suppression overrides the usual insulin-driven increase in apoCIII, resulting in lower levels of apoCIII on fat-carrying blood particles.

    Even though African-American women are more insulin-resistant, they still have less apoCIII in their fat-carrying blood particles than white women—meaning something else in their biology, not just how their body handles sugar, is causing this difference.
