Major fruit and vegetable contributors to the main serum carotenoids in the Spanish diet

Article Abstract:

Potatoes, tomatoes, green beans, pepper, carrots, artichokes, spinach, lettuces, beets, oranges, tangerines, bananas, peaches and watermelons provide 96% of the six main carotenoids in the blood serum on a yearly and a seasonal basis in Spain. The fruits and vegetables provide 3.0 mg of carotenoids/day in autumn and 4.3 mg/day in summer. Seasonal variations in the carotenoid consumption cause seasonal differences in the level of beta-cryptoxanthin and lycopene. The beta-cryptoxanthin level is maximum in winter and minimum in summer, while that of lycopene is the opposite.

Carotenoids and retinol-equivalents in food composition tables from European countries

Article Abstract:

Deharveng and colleagues's paper on the comparison of nutrients in food composition tables from nine European countries, misused and misinterpreted Granado and colleagues and Olmedilla and colleagues's data. The E-carot booklet was edited in tabular form to make available data generated by a European Project, but was cited erroneously. Certain comments of Derharveng and colleagues are disagreed with, including reference to carotenes, the HPLC technique and assessment of intake of b-carotene and individual carotenoids.

Measuring fruit and vegetable intake: is five-a-day enough?

Article Abstract:

A randomized controlled trial was designed to evaluate a self-monitoring method of 'portions' measurement of fruit and vegetable (F&V) consumption against a standard of weighed intakes. The results of the eight-week intervention trial showed that a correlation exists between the portion and weighed intakes. This indicates that the five-a-day portion measurement is a considerably good criterion and that it should be able to encourage a daily consumption of F&V greater than 400 g.
