Abstract:
... Tea is a beverage commonly consumed worldwide. Matcha is a type of green tea produced by drying and grinding tea leaves (Camellia sinensis L.) into a fine powder. Matcha contains catechin, theanine, and caffeine, which affect cognitive function. Epidemiological studies conducted in Japan have shown that green tea consumption improves cognitive impairment. Previously, we found that daily matcha int ...

Abstract:
... Seaweeds are considered a potential source of antiobesity agents. Because Caulerpa, a seaweed, has been consumed for food in Japan, China, South Korea, and Australia, we hypothesized that Caulerpa okamurae may have antiobesity effects in an animal model of high-fat diet (HFD)–induced obesity in C57BL/6 mice. Herein, we found that the ethanolic extract of C okamurae (COE) significantly inhibited li ...

Abstract:
... Investigations suggest a protective role of n-3 polyunsaturated fatty acids (PUFA) but opposing roles of n-6 PUFA in inflammation, but the effects in vivo the human are not clear. We therefore tested the hypothesis that higher intakes of n-3 PUFA and n-6 PUFA are associated with lower levels of inflammation among a population consuming a diet high in PUFA. This study aimed to assess the associatio ...

Abstract:
... It is well known that high serum uric acid (SUA) is the cause of gout and a risk factor of cardiovascular diseases. Although SUA is thought to have an association with folate metabolism through elevated production and/or damaged renal excretion, studies on functional polymorphisms of folate metabolizing are still limited, showing inconsistent findings. We hypothesized that hyperuricemia would be a ...

Abstract:
... Little is known about the relation between the activities of certain enzymes involved in endogenous fatty acid synthesis and metabolic risk factors, particularly in young adults and non-Western populations. In this cross-sectional study, we examined the associations between estimated desaturase and elongase activities and metabolic risk factors in young Japanese women. The subjects were 640 female ...

We cross-sectionally examined associations between dietary intake and serum CRP concentrations in young Japanese women. The subjects were 443 female Japanese dietetic students aged 18 to 22 years. Dietary intake was assessed with a validated, sel ...

This study was designed to verify the antihypertensive and hypolipidemic effects of A americana as physiological actions. In male spontaneously hypertensive rats (SHR) fed a diet containing 5% Apios powder for 3 weeks, ...

Abstract:
... Human milk contains numerous dietary carotenoids, including lutein and zeaxanthin (L&Z). It has been proposed that L&Z are actively transported into milk as in the eye. Because L&Z help protect the retina from blue light damage, and infants are more susceptible to blue light damage than adults, it is important to understand milk L&Z as the sole dietary source for breast-fed infants. Unfortunately, ...

Abstract:

Although alcohol intolerance is more frequently seen in Japanese, almost the same results were obtained in many studies. On the other hand, even moderate alcohol consumption increases the risks of other diseases, such as hypertension, liver ...
