Dietary interventions dramatically affect metabolic disease and lifespan in various aging models. Here, we profiled liver microRNA (miRNA), coding, and long non-coding RNA (lncRNA) expression by high-throughput deep sequencing in mice across multiple energy intake and expenditure interventions. Strikingly, three dietary intervention network design patterns were uncovered: (1) lifespan-extending interventions largely repressed the expression of miRNAs, lncRNAs, and transposable elements; (2) protein-coding mRNAs with expression positively correlated with long lifespan are highly targeted by miRNAs; and (3) miRNA-targeting interactions mainly target chromatin-related functions...

ABSTEACT Despite the reported poor dietary habits and risk of weight gain in college students, they remain understudied in Mexico. Mexican college students are in a rapidly changing economic environment; a shift from a traditional, homemade cuisine to a diet more heavily influenced by an industrialized culture seems to be occurring, potentially affecting the quality of their dietary intake. A health and nutrition survey was conducted among 450 Mexican college students to study the relationship between sociodemographic factors and diet quality...

BACKGROUND: Observational studies suggest inverse associations between wholegrain intake and body weight gain. Only few controlled intervention studies have supported this association and few compare effects of different grain varieties. OBJECTIVE: To investigate how wholegrain wheat (WGW) and rye compared with refined wheat (RW) affect body weight and composition and appetite sensation. DESIGN: Seventy overweight/obese adults participated in this 6-week randomized parallel study, in which they replaced their habitual cereal foods with RW, WGW or wholegrain rye (WGR)...

The mobile Food Record (mFR) is an image-based dietary assessment method for mobile devices. The study primary aim was to test the accuracy of the mFR by comparing reported energy intake (rEI) to total energy expenditure (TEE) using the doubly labeled water (DLW) method. Usability of the mFR was assessed by questionnaires before and after the study. Participants were 45 community dwelling men and women, 21-65 years. They were provided pack-out meals and snacks and encouraged to supplement with usual foods and beverages not provided...

We tested the hypothesis that dietary whey protein isolate (WPI) affects the intestinal mechanisms related to energy absorption and that the resulting energy deficit is compensated by changes in energy balance to support growth. C57BL/6 mice were provided a diet enriched with WPI with varied sucrose content, and the impact on energy balance related parameters were investigated. As part of a high sucrose diet, WPI reduced the hypothalamic expression of pro-opiomelanocortin gene expression and increased energy intake...

In women, bone mass undergoes changes during pregnancy and the postpartum period, which has a risk for subsequent development of osteoporosis. Thus, the present study aims to evaluate the effects of flaxseed flour in femur quality during post-weaning of dam rats. After weaning, the rats were divided into control (C, n = 7) and experimental (F, n = 7) groups treated with a diet containing 25 g of flaxseed flour in the lactating period and 15 g in the maintenance period. After 51 days post-partum, serum hormone, fatty acids composition, bone compartments, computed tomography, and biomechanical analyses were determined...

Context: The P450 enzyme CYP24A1 is the principal inactivator of vitamin D metabolites. Biallelic loss-of-function mutations in CYP24A1 are associated with elevated serum levels of 1,25-dihydroxyvitamin D3 with consequent hypercalcemia and hypercalciuria, and represent the most common form of idiopathic infantile hypercalcemia (IIH). Current management strategies for this condition include a low calcium diet, reduced dietary vitamin D intake and limited sunlight exposure. CYP3A4 is a P450 enzyme that inactivates many drugs and xenobiotics and may represent an alternative pathway for inactivation of vitamin D metabolites...

PURPOSE OF REVIEW: Growth and nutritional intake of children with cows' milk allergy and other food allergens has been thoroughly investigated in recent years across many different countries and age groups. An impaired growth in atopic children should not be attributed only to a high number of allergens and foods to be avoided, but to a general condition of 'sub-inflammation', which unfavorably affects the absorption and utilization of fuel and substrates. Atopic study participants may represent a good target for personalized nutrition and in this review we sought to outline many of the issues that should be taken into account when dietitians advise patients regarding food avoidance and expected effects on growth...

Dietary analysis of Academy soccer players highlights that total energy and carbohydrate intakes are less than optimal, especially, on match-days. As UK Academy matches predominantly kick-off at ∼11:00 h, breakfast is likely the last pre-exercise meal and thus may provide an intervention opportunity on match-day. Accordingly, the physiological and performance effects of an increased calorie breakfast consumed ∼135-min before soccer-specific exercise was investigated. English Premier League Academy soccer players (n = 7) repeated a 90-min soccer match simulation on two occasions after consumption of habitual (Bhab; ∼1100 kJ) or increased (Binc; ∼2100 kJ) energy breakfasts standardised for macronutrient contributions (∼60% carbohydrates, ∼15% proteins and ∼25% fats)...

Snacking has become more prevalent in developed countries. While poor food choices pose health risks, nutritious choices contribute important nutrients to overall dietary intakes. Young adults consumer snacks frequently and nutritious choices should be promoted among this group. However, how young adults define the term 'nutritious' currently and how they evaluate the nutritiousness of various snack foods required further investigation. The current study used a mixed methods design with 115 young adults invited to sort 32 commonly available snack foods into a line ranging from 'not nutritious' to 'very nutritious'...

This study was designed to estimate the dietary intake of total arsenic, inorganic arsenic, cadmium, mercury, sodium, and potassium by the general adult population (aged 18-65) of Valdivia, Chile. Calculations were based on a 24-h dietary recall survey. The highest dietary intake of t-As (73.0 μg/day), i-As (20.0 μg/day), Cd (18.0 μg/day), Hg (5.8 μg/day), Na(+) (3112.8 mg/day), and K(+) (2077.5 mg/day) were for 70-kg adults. Estimating carcinogenic risk (CR > 4 × 10(-4)) due to exposure to i-As indicated that consumers remain at low risk for cancer...

REVIEW
Soamsiri Niwattisaiwong, Kenneth D Burman, Melissa Li-Ng
Iodine is crucial for thyroid hormone synthesis and fetal neurodevelopment. Major dietary sources of iodine in the United States are dairy products and iodized salt. Potential consequences of iodine deficiency are goiter, hypothyroidism, cretinism, and impaired cognitive development. Although iodine status in the United States is considered sufficient at the population level, intake varies widely across the population, and the percentage of women of childbearing age with iodine deficiency is increasing. Physicians should be aware of the risks of iodine deficiency and the indications for iodine supplementation, especially in women who are pregnant or lactating...
