The Claim
In healthy young adults, a single dose of 25 mg of β-carotene consumed from raw carrots or fresh carrot juice with 50 mL of canola oil does not significantly change plasma antioxidant capacity, as measured by ORAC or TRAP assays over a 24-hour period, despite substantial increases in plasma β-carotene levels, indicating that acute β-carotene intake does not lead to measurable systemic antioxidant effects.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If healthy young adults eat raw carrots or drink carrot juice with a bit of oil, it boosts their body's β-carotene levels a lot—but that doesn’t actually improve their overall antioxidant power in the blood over the next day.
See the scientific wording
In healthy young adults, consuming 25 mg of β-carotene from raw carrots or fresh carrot juice with 50 mL of canola oil does not significantly alter plasma antioxidant capacity as measured by ORAC or TRAP assays over 24 hours, despite large increases in β-carotene levels, indicating that a single dose does not translate to measurable systemic antioxidant effects.
What the research says
1 studyThe study found that even though eating carrots or drinking carrot juice raised beta-carotene levels in the blood, it didn’t boost the body’s overall antioxidant power, just like the claim says.
