Estimated energy requirements (EERs) are important for sports based on body weight classifications to aid in weight management. The basis for establishing EERs varies and includes self-reported energy intake (EI), predicted energy expenditure, and measured daily energy expenditure. Currently, however, no studies have been performed with male wrestlers using the highly accurate and precise doubly labeled water (DLW) method to estimate energy and fluid requirement. The primary aim of this study was to compare total energy expenditure (TEE), self-reported EI, and the difference in collegiate wrestlers during a normal training period using the DLW method...

Gluten-free (GF) products are those with a natural absence or acceptable level (<20 mg/kg) of gluten. They should be a part of a diet for people with gluten-related disorders, like celiac disease. Recently the popularity of a gluten-free diet (GFD) has risen extremely, because a lot of healthy individuals exclude gluten from their menus. According to the literature data on nutritional deficiencies in the GFD, this trend seems to be risky. This paper describes the nutritional value of 14 flours from different GF raw materials from the aspect of B-group vitamin content (B1, B2, B3, B6)...

Bone mass decreases along with aging, especially for women after menopause because of lower estrogen secretion together with low calcium intake. This study was conducted to study the effect of eggshell calcium supplementation on bone mass in 54 postmenopausal Vietnamese women living in a farming area about 60 km from Hanoi, Vietnam. Sets of 3 subjects matched by age, bone mass, BMI and calcium intake were divided randomly into 3 groups with 18 subjects in each group. The eggshell calcium group was administered 300 mg/d calcium from eggshell, the calcium carbonate group 300 mg/d calcium from calcium carbonate and the placebo group received no calcium supplementation...

Egg white (EW) is known as a nutritional protein but can induce allergic reactions in humans. We investigated the dietary effects of EW and its hydrolysate (EWH), which contains less allergen, on body fat accumulation in Wistar rats fed an equicaloric high-fat and high-sucrose diet for 8 wk (Exp A). The pair-feeding of EW and equicaloric-feeding of EWH increased fecal fat excretion and suppressed lipid accumulation in the liver and muscles but not in the abdominal adipose tissues, carcass, or total body. Dietary EWH also suppressed the serum glucose level and alkaline phosphatase activity...

We propose a new oral immunotherapy (OIT) method that includes a small amount of a food allergen in the diet. However, it is not clear whether this method will induce oral desensitization and immune tolerance. Therefore, we investigated the therapeutic effectiveness using a 1% food allergen diet in an allergic mouse model. C3H/HeJ mice were sensitized to ovomucoid (OM) in alum four times at 12-d intervals. Sensitized mice were divided into two groups: the OIT group (19% casein diet with 1% OM) and the non-treated group (20% casein diet without OM)...

We examined the effect of 1α-hydroxyvitamin D3 [1α(OH)D3] on mice in the forced swimming test. Intragastric administration of 1.0 μg/kg of 1α(OH)D3 reduced immobility time in the forced swimming test. At all concentrations tested (0.5, 1.0, 2.0 μg/kg), 1α(OH)D3 had no effect on locomotor activity, compared with controls. These results suggest that 1α(OH)D3 may have antidepressant-like activity.

Glycation, a non-enzymatic glycosylation of proteins, induces tissue damage in association with various diseases and aging phenomena. Pentosidine, an advanced glycation end product, is involved in aging phenomena such as tissue stiffness. In this study, we aimed to find a potent anti-glycation food material and to verify its health benefits by clinical trial. From among 681 hot water plant extracts, lemon balm (Melissa officinalis; LB) leaf extract was selected and revealed to have more potent inhibitory activity for pentosidine formation than a representative anti-glycation agent, aminoguanidine...

Various physiological functions of dietary sphingolipids, such as preventing inflammation and improving the skin barrier function, have been recently demonstrated. The sphingolipid most commonly used as a foodstuff is glucosylceramide from plant sources, which is composed of sphingoid bases that are distinctive from those found in mammals. Although the structure of sphingoid bases in higher plants is more complicated than the structure of those in mammals, the fate of dietary sphingolipids of plant origin is still not understood...

There have been reports that hyperglycemia suppresses osteoclast (OCL) differentiation, although the underlying mechanism is poorly understood. Here we demonstrated that high glucose suppresses OCL differentiation through activation of liver X receptor (LXR) β, a recently reported glucose-sensing nuclear receptor. The effect of hyperglycemia on osteoclastogenesis was tested in RAW264.7 cells, a murine macrophage cell line. Cells were treated with receptor activator of NF-κB ligand (RANKL) under normoglycemic (5...
