健常成人を対象として,各種糖質負荷後の血糖およびインスリン分泌応答に及ぼす難消化性デキストリンの影響について検討した。さらに,食事負荷試験により,食後の血糖上昇に及ぼす影響について検討した。(1)10gの難消化性デキストリン摂取ではショ糖100g負荷後の血糖およびインスリン分泌応答を抑制し,頂値のレベルを非添加の88および69%に低下させた。また,グルコース509およびマルトデキストリン50g負荷に対して,難消化性デキストリンはインスリン分泌のみを抑制し,頂値のレベルは非添加のそれぞれ52および60%に低下した。(2)うどん定食(糖質104.2g,565kcal)摂取後の血糖応答は全般に急峻であり頂値は183.9mg/dlに達した。これに対し,菓子パン(糖質137.2g,553kcal)摂取時の頂値は145.3mg/dlであり,血糖応答は緩やかであった。これらの試験食負荷において難消化性デキストリンを緑茶あるいはコーヒーに添加して摂取させたところ,いずれも有意な血糖上昇抑制効果が認められ,頂値は88および84%に低下した。 以上の結果から,難消化性デキストリンは健常成人において食後の血糖上昇に対して一定の抑制効果が期待できるものと考えられた。

We conducted a clinical trial in order to evaluate the effects of continual ingestion of indigestible dextrin on both glucose and lipid metabolism, and fat accumulation and its distribution in human subjects. There were twelve male subjects with either serum total-cholesterol level more than 220 mg/dl or triacylglycerol level more than 150 mg/dl. Subjects were concurrently ingested l0g of indigestible dextrin with meal (3 times/day) for three month. Each was subjected to a glucose tolerance test and CT scan at umbilical level, and also taken blood sample to measure the clinical laboratory data before and after the test period. Compared to the starting levels, percent body fat in all the subjects and the area of visceral fat in subjects with obesity were significantly decreased. Although the average peak level of serum glucose was more than 200 mg/dl at 60 min after 75 g glucose administration, glucose tolerance was improved and the average levels of serum glucose at 30, 60, and 120 min were significantly reduced after the test period. Likewise, serum total-cholesterol and triacylglycerol levels were significantly reduced. No adverse event such as diarrhea was observed through the test period. In conclusion, continual ingestion of indigestible dextrin is useful for reducing the body fat accumulation, especially visceral fat.

This study was performed to evaluate the effect of agar containing jelly on human bowel habits. One g of agar was added to make a cup of 120 g of jelly. As a control, jelly which was made by same method, agar in stead of gelatin was used. Twenty four healthy adults and 21 female college students ingested from 1 to 3 cups of jelly per day considering degrees of constipation. In the healthy adults group, frequency of defecation and fecal volume were increased by the agar-agar jelly (3 cups/day) ingestion compared with non-ingestion period or the control period of a cup of gelatin jelly given (p>0.01). Furthermore the agar effects which stimulates the defecation were observed in the healthy female college students. Other bowel habits (smell, hardness and shape) were also improved in the agar-ingestion period compared with the non-ingestion period. Although some subjects were recognized abdomen symptoms by the agar-excess intake (9 cups/;day), the symptoms were disappeared after a short period. These results demonstrate that the ingestion of 3 cups of agar jelly containing 1 g of agar in a day promotes thedefecation in constipated subject and improves the fecal conditions

Colonic bacteria ferment nutrients escaped digestion and absorption in the small intestine to get energy for their proliferation, and result in luminal accumulation of their fermentation products. Colonic fermentation and their products are influenced by available substrates which vary chemical compositions and physical states. Plant fibers, resistant starch, nondigestible oligosaccharides and resistant proteins are principal substrates for colonic bacteria, and are anaerobically metabolized to various organic acids, mainly short—chain fatty acids (acetate, propionate and butyrate), ammonia and amines. Short—chain fatty acids are rapidly absorbed across Colonic mucosa and used as an energy nutrient. Short—chain fatty acids, besides their energy supplier, play a role as luminal chemical stimuli that can modify epithelial proliferation, intestinal blood flow, motility and secretion. The effects vary among short—chain fatty acids, and are dose—dependent. The sensory mechanism, therefore, of the gastrointestinal tracts must be able to detect not only the presence of individual short—chain fatty acids, but also their concentration.

Ferulic acid is a phenolic acid, ubiquitous in the plant kingdom, which can be absorbed by the small intestine and excreted through the urine. Ferulic acid is extensively reported to have preventive effects against several diseases. It can increase the ratio of HDL to VLDL+LDL cholesterol, and bioavailability of vitamin E and decrease total cholesterol in rats. It also increases vitality of sperm and is a potential medicine for male infertility. Ferulic acid shows strong antioxidant, free radical-scavenging and anti-inflammatory activity, it increases the resistance of LDL to peroxidation, protects LDL cholesterol from oxidation and prevents the oxidative modification of LDL; it is a good topical protective agent against UV radiation-induced skin damage. The most remarkable function of ferulic acid is its anti-tumor and anti-cancer effect. Several reports have suggested that ferulic acid is chemopreventive on oral cancer and that proved that ferulic acid is a potential chemopreventive component for colon cancer.

There has been increasing reports concerning several physiological responses, such as lowering of plasma cholesterol levels, modification of glycemic response, improving large bowel function, and lowering nutrients availability. According to recent evidences, most isolated fibers that are water soluble will lower plasma cholesterol in humans and animals. These include pectins, psyllium, and various gums such as guar gum, locust bean gum and modified celluloses such as carboxymethylcellulose. Consumption of fiber-rich sources containing water-soluble fibers, such as oat bran, barley (sources of β-glucan fiber), legumes, and vegetables, usually results in a lowering plasma cholesterol. In this review, I will describe two different meta-analysises and some mechanisms of these action including its effects on cholesterol synthesis rates, VLDL secretion rates, LDL turnover rates and susceptibility of LDL to oxidation.

This review described the definition of pro-and prebiotics, and their functions and problems to be solved. Probiotics and prebiotics are functional Foods, which adjust the function and balance of intestinal microflora to be more beneficial and less risky to health. Probiotics in a viable form suppress the metabolism or population of harmful bacteria. Prebiotics are indigestible and fermentable oligosaccharides and polysaccharides including dietary fibers that are stimulators to growth of beneficial intestinal bacteria and consequently suppress the growth or metabolism of harmful bacteria. Probiotics sometimes supply with themselves the deficient or abnormal intestinal microflora that appear during and after the chemotherapeutic treatment, and correct an abnormal balance of the microflora in premature infants and elderly persons. The intestinal microflora may be hypothesized to consist of different bacteraial networks, which are not always in intact form. Probiotic bacteria supplement or activate the intestinal bacterial network with defects in respect of population level or metabolic activity. In this context intestinal bacteria other than bifidobacteria and lactic acid bacteria may be also candidates for probiotic bacteria. Prebiotics activate the bacterial metabolism and increase the population of the specific bacterial species to result in the satisfaction of the bacterial network beneficial to health. Pro-and prebiotics will be furthermore anticipated in future in maintenance or improvement of the human life without risk or with risk to health, respectively.

本研究では,とうもろこし水溶性食物繊維(CSD)の血圧に対する影響を中高年男女と高血圧自然発症ラット(SHR)について検討した。用いたCSDは食物繊維含量が83.6%であった。 人に対するCSDの影響は,平均年齢60歳の18人の対象者に4週間,毎食59のCSDを湯又は茶に溶いて摂取させた。対象者は,収縮期血圧140mmHg以上と以下の2群に分けた。6名の軽度高血圧群では,CSDの摂取によって,収縮期血圧と拡張期血圧ともに有意に低下した。正常群では,収縮期,拡張期の血圧に対する影響は明確ではなかった。対象者の血漿脂質とインスリン値には有意な影響は見られなかった。また,軽度高血圧,正常両群ともに,血糖値は正常であった。 SHRラットには,5%CSD溶液を飲料水として投与し,コントロール群は蒸留水を投与し,固形飼料を投与して10週間飼育した。その結果,飼育開始1週目より,水投与群より5%CSD群の血圧の上昇は有意に抑制された。体重,肝臓などの臓器重量は両群に差はなかったが,消化管重量は有意に重く,脂肪組織は有意に小さかった。血清脂質,血糖値,インスリンには有意な影響はなかった。 これらの結果より,とうもろこしより精製した水溶性食物繊維には高血圧状態の改善の可能性が示されたが,臨床的な有効性については,その作用機構も含めてさらに検討が必要である。

We studied the effects of polydextrose (PD) on fecal weight andgastrointestinal transit time by the Latinsquare method in a cross-over fasionusing 9 male beagle dogs. Animals were divided to 3 groups; control group (PD free), PD 2.5% group and PD 5.0% group and fed with each diet for 11 days withthe wash out period of 7 days . Body weight gain, food intake and water intakewere not affected by polydextrose ingestion. The fecal weight was increased significantly in PD 5.0% group in compared with that of the control group. Also, the hardness of feces was softer in the groups fed PD than in the control group. However, the gastrointestinal transit time was not affected significantly by PD ingestion. These results suggest that PD is one of the dietary fibers which improve on defecation and fecal status.

There has been increasing reports concerning relationship between starch intake and bowel health. According to recent evidences, resistant starch(RS), a fraction of starch that survive digestion in the small intestine and reach large bowel, plays major roles in the health-promoting action of starch. In this review, we will describe some important physiological effects of RS including its historical background, formation and existence in food and functions in the large intestine. RS increased fecal mass, fecal water-holding capacity and cecal fermentation but decreased gastrointestinal transit time. Involvement of RS in lipid metabolism was also discussed. RS reduces glycemic index and improves glucose tolerance in rats. RS improves mineral availability through increased absorption in the large intestine. Some effects of RS on large intestinal defects were ascribed to fermentation products, short-chain fatty acids.

The effects of dietary fiber rich cereal-based breakfast on the increment of fecal wet weight, defecation rate and condition of evacuation were investigated in normal subjects (n=36) and the data of 29 subjects selected from 36 subjects were used for the evaluation. The study design was crossover experiment for continuous 1 weeks, and the subjects consumed 2 different test cereal flakes (cereal A, B) in random order in their breakfast. Total dietary fiber contents of the test cereals for three trials were 6.4g for cereal A 40g, 9.6g for cereal A 60g and 5.Og for cereal B 60g, respectively. The cookie as the control does not contain dietary fiber. The results obtained were as follows ;1) The fecal wet weight significantly increased with cereal A 40g, A60g and also cereal B60g and the increment was dependent on the total dietary fiber contents of the test cereals, comparing to the control . 2) The defecation rate of days and times per week were significantly increased with cereal A40g, A60g and cereal B60g, comparing of the control, respectively. 3) The condition of evacuation such as fecal form, color and smell were significantly improved in cereal A 40g and cereal A60g ingestions. 4) The wet weight of feces which makes feel defecation every day was approximately 150g. We concluded that dietary fiber rich cereal-based breakfast has a fecal bulking effect and the improvement of condition of the evacuation in the additional ingestion of 5.0-6.4g of dietary fiber in a day.
