Supplementation with iron and riboflavin enhances dark adaptation response to vitamin A–fortified rice in iron-deficient, pregnant, nightblind Nepali women1,2,3
Pregnancy impaired pupillary threshold nightblindness iron deficiency riboflavin women Nepal
2008/12/10
Background:Nightblindness affects 16–52% of pregnant women in areas of Nepal and in some cases persists after vitamin A treatment. Iron and riboflavin affect vitamin A utilization and photoreceptor fu...
Metabolic adaptation to high-fat and high-carbohydrate diets in children and adolescents
carbohydrate utilization fructose children
2016/12/29
In protocol 1, 12 children aged 6–9 y and 12 adolescents aged 13–16 y were randomly assigned in a crossover design to consume low-fat (LF), HC (25% and 60% of energy, respectively) or HF, low-carbohyd...
High-, but not low-bioavailability diets enable substantial control of women’s iron absorption in relation to body iron stores, with minimal adaptation within several weeks
serum ferritin fecal ferritin ascorbic acid
2017/1/5
Adaptation of iron absorption in response to dietary iron bioavailability is less likely in premenopausal women, who generally have lower iron stores, than in men.
Do colonic short-chain fatty acids contribute to the long-term adaptation of blood lipids in subjects with type 2 diabetes consuming a high-fiber diet?
Type 2 diabetes short-chain fatty acids high-fiber diet acetate carbohydrate intake fiber intake
2016/12/17
Background: We recently obtained evidence of long-term adaptation of blood lipids to changes in intakes of carbohydrate and fiber in subjects with type 2 diabetes.Objective: We determined th...
Marginal iron deficiency without anemia impairs aerobic adaptation among previously untrained women
Iron defi ciency without anemia iron depletion women aerobic training ·VO2 max maximal oxygen uptake serum transferrin receptors serum ferritin
2016/12/17
Background: Iron deficiency without anemia has been shown to reduce both muscle-tissue oxidative capacity and endurance in animals. However, the consequences of iron deficiency in humans remain u...
Adaptation in iron absorption: iron supplementation reduces nonheme-iron but not heme-iron absorption from food
Iron supplementation heme iron nonheme iron iron absorption fecal ferritin serum ferritin
2016/6/8
Background: Results of cross-sectional studies suggest that in
healthy people, iron absorption adapts to meet physiologic
needs and stabilize iron stores, but this has not been adequately
tested in...

Vitamin A -carotene night blindness pregnancy lactation pupil dark adaptation dark vision night vision
2016/6/8
Background: Impaired dark adaptation occurs commonly in
vitamin A deficiency.
Objective: We sought to examine the responsiveness of darkadaptation
threshold to vitamin A and -carotene supplementati...
