Het eten van quercetine, kaempferol en luteoline verlaagt kanker

Research Question:
Luteolin, kaempferol and quercetin eating lowers the chances of getting cancer?

Study Design:
This overview article contained 18 case-control studies with patients with cancer and 8585 9975 controls (persons without cancer) and 14 cohort studies with participants whose 10809 385033 cancer cases.
There was no question of publication bias.

Results and conclusions:
The researchers found in case-control studies that Luteolin, kaempferol and quercetin the combination the chance of getting cancer significantly with 27% [95% CI = 0.63-0.84] did decrease. Significant is, there is a link at a 95% reliability.

The researchers found in case-control studies that eating quercetin the chance of getting cancer significantly with 27% [95% CI = 0.62-0.86] did decrease. Significant is, there is a link at a 95% reliability.

The researchers found in case-control studies that eating kaempferol the chance of getting cancer non-significant 14% [95% CI = 0.73-1.11, p > 0.05] did decrease. Non-significant is, there is no link to a 95% reliability.

The researchers found in case-control studies that eating Luteolin the chance of getting cancer non-significant with 10% [95% CI = 0.69-1.18, p > 0.05] did decrease.

The researchers found in case-control studies that the kaempferol and quercetin, Luteolin combination the chances of getting lung cancer significantly with 33% [95% CI = 0.49-0.91] reduced.

The researchers found in case-control studies that Luteolin, kaempferol and quercetin the combination the chance of getting colon cancer significantly with 25% [95% CI = 0.57-0.98] reduced.

The researchers found the combination in cohort studies that quercetin, Luteolin and kaempferol the chance of getting cancer significantly with 11% [95% CI = 0.80-1.00] reduced.

The researchers found in cohort studies that eating quercetin significantly the chances of getting cancer by 18% [95% CI = 0.71-0.96] did decrease.

The researchers found in cohort studies that eating kaempferol the chance of getting cancer significantly with 12% [95% CI = 0.78-0.99] did decrease.

The researchers found in cohort studies that eating Luteolin the chance of getting cancer non-significant with 5% [95% CI = 0.67-1.34, p > 0.05] did decrease.

The researchers concluded that the combination kaempferol and quercetin, Luteolin the chance of getting cancer, especially lung and colon cancer reduced.

Additional information about El Mondo:
Flavones and flavonolen are flavonoids.
Flavones in food are almost always from the glycosides of Luteolin and apigenin. Flavones are found in gipsy Wort, artichoke, olives, parsley and celery.
Flavonolen are found in onions, kale, leek, broccoli and blueberry. The main representatives of this group are quercetin and kaempferol.

The best way is through sufficient flavonoids within 200-300 grams of vegetables, 2-5 pieces of fruit and 2-3 glasses of wine per day.

Conclusion of a review article by weighs heavier than cohort studies of case-control studies because cohort studies are less prone to errors than case-control studies. The more errors in a study are, the less reliable the conclusion is.
