“…Published data suggest that mean α-tocopherol intakes in adults in some European countries (Finland, Sweden) (Amcoff et al, 2012;Helldán et al, 2013) are higher than those observed in the USA, where γ-tocopherol intakes are generally reported to be higher than in the EU (Gao et al, 2004;Maras et al, 2004;Dixon et al, 2006;Mahabir et al, 2008;Signorello et al, 2010;Yang et al, 2014a;Yang et al, 2014b).…”

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) derived Dietary Reference Values (DRVs) for vitamin E. In this Opinion, the Panel considers vitamin E as α-tocopherol only. The Panel considers that Average Requirements (ARs) and Population Reference Intakes (PRIs) for vitamin E (as α-tocopherol) cannot be derived for adults, infants and children, and therefore defines Adequate Intakes (AIs), based on observed intakes in healthy populations with no apparent α-tocopherol deficiency in the EU. This approach considers the range of average intakes of α-tocopherol and of α-tocopherol equivalents estimated by EFSA from dietary surveys in children and adults in nine countries. The Panel notes the uncertainties in the available food composition and consumption data, the fact that most EU food composition databases contain values for vitamin E as α-tocopherol equivalents, as well as the contribution of average α-tocopherol intakes to average α-tocopherol equivalent intakes in these countries. For adults, an AI for α-tocopherol is set at 13 mg/day for men and 11 mg/day for women. For children aged 1 to < 3 years, an AI for α-tocopherol is set at 6 mg/day for both sexes. For children aged 3 to < 10 years, an AI for α-tocopherol is set at 9 mg/day for both sexes. For children aged 10 to < 18 years, an AI for α-tocopherol is set at 13 mg/day for boys and 11 mg/day for girls. For infants aged 7-11 months, an AI for α-tocopherol of 5 mg/day is derived by extrapolating upwards from the estimated α-tocopherol intake in exclusively breast-fed infants aged 0-6 months and rounding. For pregnant or lactating women, the Panel considers that there is no evidence for an increased dietary α-tocopherol requirement, and the same AI is set as for non-pregnant non-lactating women. Vitamin E is a fat-soluble vitamin. Previously, the term vitamin E was used as the generic term for four tocopherols (α, β, γ, δ) and four tocotrienols (α, β, γ, δ), which are organic compounds that possess antioxidant activity to a different degree. Factors have been used to convert food contents of tocopherols and tocotrienols to α-tocopherol equivalents. In this Opinion, based on the available evidence and in line with other authoritative bodies, the Panel considers vitamin E as being α-tocopherol only. Its naturally occurring form is RRR-α-tocopherol. Commercially available forms of α-tocopherol include RRR-α-tocopherol, a synthetic form that contains in equal proportions the eight stereoisomers of α-tocopherol (RRR-, RRS-, RSR-, RSS-and their enantiomers SSS-, SSR-, SRS-, SRR-) and is called all-rac-α-tocopherol, and their esterified forms. © EuropeanEfficient α-tocopherol absorption requires the presence of fat. The Panel considered that the average α-tocopherol absorption from a usual diet is about 75 %. This is based on the means observed in two balance studies and in a kinetic study using a multi-compartmental model of α-tocopherol metabolism. After its intestinal absorption, α-toc...

“…The self-administered FFQ is the primary method of dietary assessment used in epidemiological studies ( 11 ) , owing to its capability of capturing a long-term dietary behaviour, low participant burden and ease in data processing. A new FFQ was developed to assess a comprehensive antioxidant intake profile containing vitamin C, vitamin E, carotenoids, flavonoids and proanthocyanidins, as well as total antioxidant capacity (TAC), an integrated measure of the ‘quenching abilities’ of antioxidants ( 12 ) . This FFQ provided a reasonable validity in a sample of American college students ( 12 ) .…”

Objective: To validate an FFQ to assess antioxidant intake in overweight postmenopausal women. Design: A seventy-four-item antioxidant 1-month FFQ was developed based on major antioxidant sources in the American diet. Forty overweight postmenopausal women participated in a 9-month observational study and completed four sets of FFQ and 7 d food record (7dFR) every 3 months. Twelve-hour fasting blood was collected for plasma antioxidant measurement at the first visit. Setting: Connecticut, USA. Subjects: Forty overweight postmenopausal women. Results: Spearman correlation coefficients of 1-month antioxidant intake estimated from the first set of FFQ and 7dFR ranged from 0?34 to 0?87, except for g-tocopherol.The proportion of participants categorized into the extremely opposite tertiles averaged 7 %. Significant correlations were observed for diet-plasma vitamin C, a-tocopherol and carotenoids (P , 0?05). No time effect was observed on the dietary antioxidant intakes estimated from four 7dFR and four FFQ. Dietary antioxidants estimated from averaged four 7dFR showed moderate to high correlation with those estimated from averaged four FFQ and from each FFQ collected every 3 months. Bland-Altman plots did not show any systematic bias. Averaged misclassifications were below 10 % between these two instruments. Conclusions: These findings attested a reasonable validity and a good acceptance of this 1-month FFQ in assessing both short-term and long-term diverse antioxidant intakes in these overweight postmenopausal women. The use of this FFQ in associating antioxidant intake with disease risk needs further investigation.

Dietary β-Cryptoxanthin and α-Carotene Have Greater Apparent Bioavailability Than β-Carotene in Subjects from Countries with Different Dietary Patterns

et al. 2020

β-carotene, α-carotene and β-cryptoxanthin are greater contributors to vitamin A intake than retinol in the human diet for most people around the world. Their contribution depends on several factors, including bioavailability and capacity of conversion into retinol. There is an increasing body of research showing that the use of retinol activity equivalents or retinol equivalents could lead to the underestimation of the contribution of β-cryptoxanthin and of α-carotene. The aim is to assess their apparent bioavailability by comparing concentrations in blood to their dietary intakes and identifying the major food contributors to their dietary intake. Dietary intake (3-day 24-h records) and serum concentrations (by HPLC) were calculated in normolipemic subjects with adequate retinol status (≥1.1 µmol/L) from our studies (n = 633) and apparent bioavailability calculated from 22 other studies (n = 29,700). Apparent bioavailability was calculated as the ratio of concentration in the blood to carotenoid intake. Apparent bioavailabilities for α-carotene and β-cryptoxanthin were compared to those for β-carotene. Eating comparable amounts of α-carotene, β-cryptoxanthin and β-carotene foods resulted in 55% greater α-carotene (95% CI 35, 90) and 686% higher β-cryptoxanthin (95% CI 556, 1016) concentrations than β-carotene in blood. This suggests differences in the apparent bioavailability of α-carotene and β-cryptoxanthin and even larger differences with β-cryptoxanthin, greater than that of β-carotene. Four fruits (tomato, orange, tangerine, red pepper) and two vegetables (carrot, spinach) are the main contributors to their dietary intake (>50%) in Europeans.
