Infant growth and tolerance with a formula based on novel native demineralized whey: A randomized double-blind pilot study.

OBJECTIVES: The aim of the study was to evaluate the effects on infant growth and tolerance of a Test infant formula based on a novel whey extraction and demineralization process, compared to a Standard formula and a breastfed reference arm. METHODS: Healthy term infants (n = 61) aged up to 21 days were randomized to Test or Control formula. A breastfed group (n = 39) served as a reference. Growth, tolerance, adverse events, and sleep were evaluated every month until 6 months of age. Plasma amino-acid concentrations at 3 months of age were measured in a subgroup population. RESULTS: Growth curves of all infants globally agreed with World Health Organization standards across the 6-months period study. Regarding tolerance, no difference between the formula-fed groups was observed on daily number of crying episodes, intensity or time to onset of regurgitations, and stool frequency or consistency, except at 5 months with infants in the Control group having more watery stools. Plasma concentration of some amino acids differed between the groups, especially tryptophan concentration which was higher in infants fed with the Test formula. In parallel, total sleep duration was longer in these infants at 2, 3, and 5 months of age, corresponding to an increase in daytime sleep. CONCLUSIONS: Test formula supported an adequate infant growth from birth to 6 months of age and was well-tolerated by all infants. An increase in total sleep at several months was also observed with the Test formula.

The ALGOVUE Clinical Trial: Effects of the Daily Consumption of Eggs Enriched with Lutein and Docosahexaenoic Acid on Plasma Composition and Macular Pigment Optical Density.

BACKGROUND: Carotenoids and docosahexaenoic acid (DHA) were identified as essential components for eye health and are both naturally present in eggs. OBJECTIVE: We aimed to evaluate the effect of the daily consumption of two eggs enriched with lutein/zeaxanthin and DHA on macular pigment optical density (MPOD) and on circulating xanthophyll and fatty acid concentrations in healthy participants. METHODS: Ninety-nine healthy volunteers consumed either two standard eggs or two enriched eggs per day for 4 months. MPOD was measured at baseline (V0) and at follow-up (V4) using a modified confocal scanning laser ophthalmoscope (primary outcome). Blood samples were collected to determine total plasma and lipoprotein fatty acids and lutein/zeaxanthin compositions at V0 and V4 (secondary outcomes). RESULTS: A slight but significant increase in MPOD was observed for all study participants consuming two eggs per day for 4 months at all eccentricities (0.5°, 1°, 2°, and 4°). Plasma and lipoprotein lutein, zeaxanthin, and DHA concentrations significantly increased in both groups but were greater in the enriched group (for the enriched group (V0 vs. V4): lutein, 167 vs. 369 ng/mL; zeaxanthin, 17.7 vs. 29.2 ng/mL; DHA, 1.89 vs. 2.56% of total fatty acids). Interestingly, lutein from high-density lipoprotein (HDL) was strongly correlated with MPOD at 0.5 and 1° eccentricities (rho = 0.385, p = 0.008, and rho = 0.461, p = 0.001, respectively). CONCLUSIONS: MPOD was slightly increased in both groups. Lutein, zeaxanthin, and DHA plasma concentrations were strongly enhanced in the enriched group compared with the standard group. A significant correlation was found between MPOD level and lutein concentration in HDL.

Long term effect of spa therapy combined with patient education program on subjects with overweight and obesity - A controlled study.

The aim of this single center prospective controlled study in volunteers with obesity and overweight was to evaluate the effect of a patient therapeutic education program (PTE group) combined with spa therapy on weight, physical activity, eating habits and quality of life versus spa therapy alone (control group). The main endpoint was weight change at 5 months after the end of the program. The PTE group of 151 subjects with obesity or overweight followed a 3-week program combining patient education with spa therapy and 189 attended a course of spa therapy alone. At 5 months significant loss was observed in the PTE group compared to controls (-2.69kg vs -1.24kg, p=0.008), a relative weight loss of -2.8% vs -1.3%. At 11 months after spa therapy, only the PTE group maintained a weight loss in addition to the weight loss obtained during spa therapy. The control group returned to the weight they had at the end of spa therapy. In both groups, a significant increase in physical activity was observed at 5 (p<0.001) and 11 months (p<0.001) with a significant better improvement in the PTE group. In addition, while in both groups some quality of life parameters and dietary choices were improved, the improvement (more fruit, vegetables, fish and water) was significantly higher in the PTE group, at both 5 and 11 months after spa therapy. In conclusion, while spa therapy alone initiated positive changes in weight loss, physical activity and some quality of life parameters, the PTE program enhanced this effect.

Incorporation of lutein and docosahexaenoic acid from dietary microalgae into the retina in quail.

Lutein and docosahexaenoic acid (DHA) are associated with the prevention of age-related macular degeneration (AMD). Since microalgae are potent natural sources of these nutrients, their nutritional value should be evaluated based on the bioavailability of lutein and DHA for the retina via the plasmatic compartment. In this study, quail were fed for 5 months either with a diet supplemented or deprived with microalgae rich in lutein and DHA. In the microalgae-fed group, the retinal concentrations of lutein and zeaxanthin gradually increased whereas in plasma, these compounds started to increase from the first month of supplementation. We also observed a significant increase in retinal and plasmatic levels of DHA in the microalgae-fed group. In conclusion, the plasmatic and retinal contents of lutein and DHA were significantly increased in quail fed with lutein- and DHA-rich microalgae. Food fortification with microalgae may be an innovative way to increase lutein and DHA consumption in humans.
