L-theanine, an amino acid contained in green tea leaves, is known to block the binding of L-glutamic glutamate receptors brain, and has been considered cause anti-stress effects by inhibiting cortical neuron excitation. Both L-theanine caffeine, which contains, have highlighted for their beneficial on cognition mood. In this study, we investigated orally administered or caffeine mental task performance physiological activities under conditions physical psychological stress humans. Fourteen...
Muscle atrophy (loss of skeletal muscle mass) causes progressive deterioration function. Recently, excessive intake fats was suggested to induce insulin resistance, followed by atrophy. Green tea extracts (GTEs), which contain polyphenols such as epigallocatechin gallate, have beneficial effects on obesity, hyperglycemia, and but their against are still unclear. Here, we found that GTEs prevented high-fat (HF) diet–induced weight loss in senescence-accelerated mouse prone-8 (SAMP8), a murine...
γ-Aminobutyric acid (GABA) is an amino found in unpolished rice, chocolate, tea, and other foods. It important inhibitory neurotransmitter. However, the influence of GABA on object recognition working memory still unknown. In this study, effects novel (NOR) were examined. The proper retention interval delay time also investigated for NOR test T-maze test, respectively. Male 3-wk-old Wistar rats allowed free access to food water containing 0.5% or 1% a month. After that, performed at 48 h 900...
The purpose of this study was to investigate the electroencephalographic activity after smelling two kinds green tea and examine any anti-stress effects tea. Ten subjects (6 male 4 female) participated in study. We used tea, Sagara Shaded White Tea, which were made from same kind leaf but by different manufacturing processes. an arithmetic task auditory discrimination test mental stress. An electroencephalogram (EEG) recorded before samples performing tasks. Subjective ratings about status...
Green tea has become renowned for its health benefits. In this study, we investigated the anti-stress effect of two kinds green against a mental stress task load.Warm water, ordinary (Sagara), and shaded white tea, which contains more amino acid components than Sagara, were used as test samples in randomized cross-over design study. Eighteen students (nine male nine female) participated three experimental trials on different days at intervals seven days. Saliva was collected before beverage...
Growing attention has been paid to the effects of food flavor components on alleviating negative brain functions caused by stressful lifestyles. In this study, we investigated effect two kinds black tea aromas physical and psychological stress induced Uchida-Kraepelin test, based salivary chromogranin-A (CgA) levels as a marker subjective evaluations (Profile Mood States). Compared with water exposure control, inhaling aroma (Darjeeling Assam in study) lower CgA concentration after 30 min...
Unhealthy diet promotes progression of metabolic disorders and brain dysfunction with aging. Green tea extracts (GTEs) have various beneficial effects alleviate disorders. GTEs neuroprotective in rodent models, but their against models aging fed unhealthy diets are still unclear. Here, we showed that attenuate high-fat (HF) diet-induced senescence-accelerated mouse prone-8 (SAMP8), a murine model senescence. SAMP8 mice were control diet, HF or 0.5% (HFGT) for four months. The reduced memory...
We investigated the memory task performance and central nervous activity after smelling two kinds of pan-fired Japanese green tea to examine their physical psychological effects. Twenty eight subjects participated in this study. used Koushun Kouju for test samples, which were made by different manufacturing processes. After each odor sample, a an arithmetic mental stress. Electroencephalogram (EEG) was recorded before EEG estimated 4 frequency bands (alpha 1, alpha 2, beta 1 2). The profiles...
It is still unclear in the literature whether it possible to use brain wave power measure a subject's personal preference for different beverages. We conducted two experiments investigate relations between subjective evaluation of beverage and physiological responses by measuring activities central nervous system before after intake kinds beverage. First, we took measurements when subjects ingested water temperatures studied differences results. then performed similar experiment using...

Twenty eight subjects (14 male 14 female) participated in study. We used Koushun Kouju for test samples, which were made by different manufacturing processes. After each odor sample, a an arithmetic mental stress. Electroencephalogram (EEG) was recorded before EEG estimated 4 frequency...
摂取した食物が脳内代謝を変動させ,脳機能活動に影響を及ぼすことが多く報告されてきた.これまでにも同様のタイトルでの記述をしており(1),今回は,比較的最新の動向について紹介する.また,脳機能に食品や食品成分がどのような影響を与えるか,それをどのように評価するかについての新しい手法も開発されてきており,食品や食品成分の情動への影響などの脳機能効果がより解明されやすくなった.
We propose an automated image analysis of facial expressions for measuring interventional effect diet with respect to the mental aspect. Facial expression that is noninvasive and noncontact human subjects promising in sense it can measure our natural behaviors due emotional biological states safely low cost lengthy period time. This paper shows analyses on comparison between before after ingest test samples, also effects different samples both outputs from conventional sensors muscle...
