The diverticulosis of the gastrointestinal tract is a widespread senile disease. The dependence of the diverticulosis on age is investigated on the basis of 1 000 proven cases of this disease. The importance of the anatomicomorphological lesions of the organs at old age as its cause is pointed out. The males seem to be affected by the diverticulosis somewhat more than the females, whereas its percental manifestation in the different organs is about equal for both sexes. It prevails in the colon with 48.4% and in the duodenum with 35.4% of all cases of organ diverticulosis. The existence of constitutional associations with other diseases, such as diabetes mellitus, is discussed. Finally, the therapeutic problems of the diverticulitis and their dependence on age are examined.

Nutritional factors in the aetiology of coronary heart disease, maturity-onset diabetes, diverticular disease and dental caries are discussed. Four principles for a prudent diet are suggested, namely: avoid excess intake of energy, increase dietary fibre intake, reduce total fat intake to approximately 30 per cent of energy intake, take a high proportion of fat as the polyunsaturated form.

Crude fiber (CF) is the residue of plant food left after extraction by dilute acid followed by dilute alkali. Dietary fiber (DF), a new term, is the residue of plant food resistant to hydrolysis by human alimentary enzymes. DF is composed of cellulose, hemicellulose, and lignin; these constituents are not reported in food tables. For instance, whole wheatmeal has DF about 11%, CF about 2%. It is suggested that a new term, dietary fiber complex (DFC), should include all substances of DF plus all chemical compounds naturally associated with, and concentrated around, these structural polymers. CF supplies from starchy staples, wheat and potato, in England and Wales were probably stationary from 1770 to 1860, fell greatly from 1860 to 1910, rose during food controls in 1942 to 1953, and declined slightly from 1954 to 1970. It is postulated that fiber is a protective factor against certain colonic disorders, such as diverticular disease, and certain metabolic diseases, such as ischemic heart disease, diabetes mellitus, and obesity. These three diseases had changing trends of mortality rates in England during the food control years. Westernization of African diets is accompanied by a large fall in CF from starchy foods and vegetables and an increased prevalence of the same three diseases.

There were found 368 cases (4.5 percent) of diverticulosis of the intestine based on 8124 autopsies in the years of 1979 till 1988 with regard to their localisation, complications and accompanied diseases. In 174 of 368 cases clinical files could be examined and integrated in the evaluation. Sigmoid diverticula were most frequently followed from duodenal diverticula chiefly in the immediate vicinity of the "Papilla of Vateri". Constipation, stomachache, haemorrhoids and spasm of the anal sphincter were typical complaints. One during lifetime known diverticulosis was noted only approximately half on the autopsy application as a second disease. The autopsy results a complication of diverticula (mostly with a peritonitis) in 39 percent as the primary cause of death. Most frequently complication was a diverticulitis (in 16.8 percent refer to the total number). Arteriosclerosis, hypertension and/or diabetes (so called "civilization diseases") were in the main accompanied diseases, which were found too. Surgical intervention took place principal under suspicion of malignoma or as an "acute abdomen". Non-characteristic complaints (protraction by the physician) and the ignorance of the illness among the population (protraction by the patients) are disadvantageous to the identification of the diverticulosis. Because the diverticulosis as a disease of the economic developed countries represents a growing problem ought to direct more attention to prevention, which consists in application of food rich in ballast-substances and the treatment of the constipation.

The term "obstructive colitis" refers to ulceroinflammatory lesions occurring in the colon proximal to an obstructing or potentially obstructing lesion. We studied nine cases identified over a 9-month period. The patients were predominantly female (only one was male), elderly (mean age, 73), and usually had hypertension, diabetes, or other prior chronic illness. The colonic obstruction was due to adenocarcinoma in seven cases and to diverticular disease in two cases. Areas of colitis occurred either as circumscribed ulcers 0.5-2 cm in diameter (three cases) or as confluent circumferential lesions 8-25 cm in length; they were always separated from the more distal obstructing lesions by a segment of normal colon measuring 2.5-35 cm (mean, 14.6 cm). The involved area of colon was usually only mildly dilated; it exhibited moderate thickening of the wall and had a granular luminal surface accentuated in areas by deeper longitudinal or transverse ulcers. Often there were scattered pseudopolyps, and the margin separating the lesion from normal mucosa was well demarcated and irregular. In one case, two distinct separate areas of colitis were present; in another, the appendix was acutely inflamed. Microscopically, the lesions were composed of granulation tissue with a mixed acute and chronic inflammatory infiltrate that replaced the mucosa and often the submucosa; sometimes it extended into the muscularis propria, with associated peritonitis and perforation. Many of the features of obstructive colitis suggest an ischemic origin, probably mainly due to hypoperfusion following raised intramural pressure, but altered fecal flora may have a synergistic effect. The features of the disease are usually sufficiently characteristic to distinguish it from Crohn's disease and other forms of colitis. Complications include peritonitis, perforation and breakdown of anastomoses made through involved segments of colon that may appear externally normal at surgery.

This report defines dietary fibre and summarizes its effects on dental, gastrointestinal and metabolic diseases. A higher intake of dietary fibre is important in prophylaxis of caries, paradentosis, constipation, diverticulosis, colon cancer, diabetes and hypercholesteraemia. An ideal preparation must have the following abilities: It should be coarse, hard and swallowable and without cariogenic sugars in order to prevent dental diseases. It should be a mixture of several kinds of fibre getting water binding capacity and bile acid binding capacity. Mechanical crushing and heatening of fibre are to be avoided. The preparation should not contain phytic acid.

Technological advances have reduced and refined man's plant food intake and consequently brought about an unprecedented decline in his consumption of dietary fibre (DF). The emergence of certain diseases selectively in regions which have been affected the most by this dietary change has led to an enhanced awareness of the functions of DF. DF is a heterogeneous group of substances which resist digestion by the endogenous enzymes of the human gut, although they are fermented to a substantial extent by the bacterial flora of the large intestine. Chemically, DF essentially consists of nonstarch polysaccharides and lignin, and its major constituents are cellulose, hemicelluose, lignin and pectin. The physiological effects of DF are attributable largely to its physicochemical properties. DF primarily affects gastrointestinal (GI) function; its effects are observable at all stages from ingestion through defaecation. It restricts caloric intake, shows gastric and small intestinal transit, and affects the activity of digestive enzymes and release of GI hormones. Its overall impact is to reduce apparent digestibility of nutrients marginally but consistently. In the large intestine, DF accelerates transit, supports bacterial growth and serves to hold water. As a result, the faecal weight and water content increase, and the transit time generally becomes shorter. Secondary to its GI effects, DF attenuates postprandial glycaemia and has long term effects on glucose tolerance and lipoprotein metabolism. These effects have important implications in the aetiopathogenesis of constipation and its sequelae including diverticulosis, cholesterol gallstones, colorectal cancer, obesity, diabetes mellitus and atherosclerosis. DF has traditionally been used therapeutically for constipation; now its use in diabetes is also well established. Our appreciation of the role of DF in human nutrition has undergone a major change in the last two decades. From a redundant constituent of plant foods, it has now moved to the position of an essential nutrient, the deficiency of which seems to have serious consequences.

Increased intake of fiber and starchy foods has been recommended in the treatment or prevention of a range of diseases including dumping syndrome, hyperlipidemia, gallstones, diabetes, Crohn's disease, constipation, irritable bowel, diverticular disease, and colonic cancer. The nature and physiological effects of fiber are diverse. However in general, insoluble fibers increase fecal bulk and decrease transit time. On the other hand, soluble fibers have metabolic effects secondary to reducing the rate of small intestinal absorption. In the colon, along with undigested starch, they are largely fermented yielding short-chain fatty acids which may have further metabolic effects. At present although much further work is required, the clinical management of hyperlipidemia, diabetes, constipation, and diverticular disease have already been significantly influenced as a result of the ideas and experimental evidence generated by the fiber hypothesis.

It is accepted nowadays that dietary fiber is an important constituent of the diet. There is growing evidence that the low fiber Western diets and the low consumption of whole grain products are important factors in several common diseases of the large bowel. Cereal fiber differs from that present in vegetables and fruit. A low intake of cereal fiber has been implicated in cancer of the large bowel, diverticular disease of the colon and coronary heart disease. High fiber diets are often prescribed for diabetes. Although fiber consumption by British and American consumers has decreased over the past century, consumption of whole wheat breads and fiber-rich breakfast cereals has received new attention during the past ten years.

Recent studies of vegetarian diets and their effects on morbidity and mortality are reviewed. Vegetarian diets are heterogeneous as are their effects on nutritional status, health, and longevity. Mortality rates are similar or lower for vegetarians than for nonvegetarians. Risks of dietary deficiency disease are increased on vegan but not on all vegetarian diets. Evidence for decreased risks for certain chronic degenerative diseases varies. Both vegetarian dietary and lifestyle practices are involved. Data are strong that vegetarians are at lesser risk for obesity, atonic constipation, lung cancer, and alcoholism. Evidence is good that risks for hypertension, coronary artery disease, type II diabetes, and gallstones are lower. Data are only fair to poor that risks of breast cancer, diverticular disease of the colon, colonic cancer, calcium kidney stones, osteoporosis, dental erosion, and dental caries are lower among vegetarians. Reduced risks for chronic degenerative diseases can also be achieved by manipulations of omnivorous diets and lifestyles.
