The Claim
In healthy adults aged 20–30, ingestion of 25 mg of β-carotene from either raw carrots or fresh carrot juice, consumed with 50 mL of canola oil, results in peak plasma β-carotene concentrations at 1.5 hours post-ingestion, with concentrations returning to baseline by 24 hours, indicating rapid absorption and clearance kinetics for both food forms.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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 young, healthy adults eat raw carrots or drink fresh carrot juice with a little canola oil, their bodies absorb the beta-carotene quickly—peaking in the blood in just 1.5 hours—and it’s all cleared out within 24 hours.
See the scientific wording
Consumption of 25 mg β-carotene from either raw carrots or fresh carrot juice with 50 mL of canola oil leads to peak plasma β-carotene concentrations at 1.5 hours post-ingestion in healthy adults aged 20–30, with levels returning to baseline by 24 hours, indicating rapid absorption and clearance kinetics for both forms.
What the research says
1 studyThe study found that carrot juice gives a much bigger boost in beta-carotene than raw carrots, and it doesn’t show that levels go back to normal by 24 hours for both, so the claim isn’t fully backed up.
