Influence of Proteins on the Bioavailability of Carotenoids

Summary

A postprandial intervention study is conducted on healthy male subjects to evaluate whether the addition of proteins (why protein isolate, soy protein) can help to increase the bioavailability of carotenoids from a tomato/carrot beverage.

Conditions

• Absorption; Chemicals
• Healthy Diet
• Metabolism

Interventions

OTHER

Intervention with soy protein isolate

Test meals will be served to the subjects, containing soy protein isolate: 350 mL carrot/tomato juice (50:50, v/v), with 30 g added soy protein, plus 5 ml peanut oil as morning test meal, served together with 40 g toasted bread and 20 g of cream-cheese plus 10 g margarine.

OTHER

Intervention with whey protein

Test meals will be served to the subjects, containing soy protein isolate: 350 mL carrot/tomato juice (50:50, v/v), with 30 g added whey protein isolate, plus 5 ml peanut oil as morning test meal, served together with 40 g toasted bread and 20 g of cream-cheese plus 10 g margarine.

OTHER

Intervention without protein addition

Test meals will be served to the subjects, containing soy protein isolate: 350 mL carrot/tomato juice (50:50, v/v), plus 5 ml peanut oil as morning test meal, served together with 40 g toasted bread and 20 g of cream-cheese plus 10 g margarine.
