There is a lack of agreement in the literature as to whetlher or not fructose occurs in the roots of the carrot. Apparenitly the reducing sugar is thought by many to be composed largely or entirely of glucose, and that little or no fructose is present. Sucrose and glucose have been reported by DIETRICH (5), RITTENHAUSEN (5), PLATENIUS (8, 9), BARNES (1), and WERNER (14). Sucrose was identified ...

Pursuing personal goals for delayed rewards (e.g., exercising to improve health) often provides consumers with immediate rewards (e.g., a fun workout) in addition to the delayed rewards they receive. With regard to health and academic goals, we find that attending to the immediate rewards of health and academic activities increases persistence in these activities to a greater extent than attend...

BACKGROUND Lutein is a hydroxy-carotenoid constituting the macular pigment of the human retina. Increasing lutein intake from foods could increase the density of this pigment and decrease the risk of developing macular degeneration. Yellow carrots are a novel food source that could increase lutein consumption. OBJECTIVE We evaluated and compared lutein uptake and clearance in humans from gene...

BACKGROUND As the first pathway-specific enzyme in carotenoid biosynthesis, phytoene synthase (PSY) is a prime regulatory target. This includes a number of biotechnological approaches that have successfully increased the carotenoid content in agronomically relevant non-green plant tissues through tissue-specific PSY overexpression. We investigated the differential effects of constitutive AtPSY ...

O'Bannon and Taylor reported that carrot disks on 1% agar were suitable for culturing Pratylenchus brachyurus (4). We found that they are suitable also for Pratylenchus vulnus, and easier to prepare than the alfalfa tissue we have used in the past (3). Our observations on carrot disks during the last 3 years may be useful to others. Initially, many of the carrot disks rotted, and a variety of s...

OBJECTIVE The goal was to study how popular licensed cartoon characters appearing on food packaging affect young children's taste and snack preferences. METHODS Forty 4- to 6-year-old children tasted 3 pairs of identical foods (graham crackers, gummy fruit snacks, and carrots) presented in packages either with or without a popular cartoon character. Children tasted both food items in each pai...

The vitamin A values of plant foodstuffs, as found by biological tests with rats, are often lower than would have been expected from the results of chemical estimations of the carotene content. The causes of this discrepancy presumably lie mainly in a less complete absorption of carotene from vegetables than from the oily solution in which the international /3-carotene standard is administered,...

carotenoids are red, orange and yellow pigments, which are widely distributed in fruit and vegetables. the aim of this research is to investigate the effect of conventional, high pressure and microwave cooking on the concentrations of β-carotene in carrot and sweet corn. raw carrots were washed, peeled and diced to a uniform size and then frozen at -70°c. sweet corn was also provided in a simil...

The spectrum of nitrofurantoin lung injury continues to widen. The case histories are presented of two patients who developed lung disease associated with the use of nitrofurantoin with histological features of bronchiolitis obliterans organising pneumonia (BOOP), a rare but recognised form of drug induced injury. The two middle aged women presented with respiratory symptoms after prolonged tre...
