A study was made of the effects of fructooligosaccharides, which exist widely inplants such as onion, edible burdock, wheat etc., on the human and animal intestinal flora. Fructooligosaccharides are produced from sucrose with the aid of β-fructofuranosidase from Aspergillus niger on a commercial scale by Meiji Seika Kaisha, Ltd.(Neosugar, Meioligo®). It has been found that they are not hydrolyzed by any digestive enzymes of humans and animals. Moreover utilization byvarious kinds ofintestinal bacteria indicated that Bifidobacterium spp., the Bacteroides fragilis group, Peptostreptococcus spp. and Klebsiella pneumoniae can utilize these saccharides, but Clostridium perfringens, Escherichia coli and others cannot. The fructooligosaccharides are selectively utilized, particularly by bifidobacteria.The clinical studies showed that fructooligosaccharides administration improved the intestinal flora, with subsequent relief of constipation, improved blood lipids in hyperlipidemia, and suppressed the production of intestinal putrefactivesubstances.

This was conducted to examine the effects of brown seaweed (wakame) on blood pressure and serum biochemical parameters in hypertensive subjects. Of the 37 elderly out-patients with hypertension who started the study, 36 of them completed it. This study was a randomly assigned, case-controlled one. Nineteen patients received a daily dose of 5g of dried wakame powder packed in 12 capsules. Eighteen gender-matched subjects with age difference±2 years, and starting time of participation within±2 weeks, were selected as the control group. Patients visited the clinic every 4 weeks. The observation period was 8 weeks. In the wakame group, the average amount of wakame ingested was 3.3g. The systolic blood pressure (SBP) in this group dropped 13mmHg below the baseline (p<0.01) after 4 weeks, and 8mmHg (p<0.05) after 8 weeks. The diastolic blood pressure (DBP) decreased by 9mmHg (p<0.01) after 4 weeks and by 8mmHg (p<0.05) after 8 weeks. In the control group, no significant changes were seen in either SBP or DBP. However, the differences in reduction in SBP and DBP were significant between the wakame and control groups. Regarding clinical chemistry data, hypercholesterolemia in the wakame group decreased by 8% after 4 weeks. No other abnormal changes were observed in either group. We conclude that wakame has beneficial effects as a supplemental regimen in the treatment of hypertension.
