“…More folds in the colon would result in increases in the propulsive force, increasing rate of bolus passage along the colon. The increasing fiber content in leaf meal based diets is likely to have stimulated colon motility (Staniforth, Baird, Fowler, & Lister, 1991;Brownlee, Dettmar, Strugala, & Pearson, 2006;Zeng, Lazarova, & Bordonaro, 2014) resulting in increases in the number of colon folds. Such segmental contractions result in increased water absorption and electrolyte exchange (Maykel & Opelka, 2004) and possibly reduced contact time between digesta and intestinal lumen.…”

“…Such segmental contractions result in increased water absorption and electrolyte exchange (Maykel & Opelka, 2004) and possibly reduced contact time between digesta and intestinal lumen. This is important as it reduces colon mucosal exposure to potential damaging agents of either endogenous or exogenous origin (Brownlee et al, 2006) while allowing the colon to absorb as much water as is possible.…”

The effect of A. angustissima leaf meal based diets on intestinal physiology and dressed carcass weight was investigated on 150 day old chicks. Three diets, 0, 5 and 10% A. angustissima were used in a three phase feeding programme. At days 14, 28 and 42, two birds from each replicate were slaughtered, dressed and weighed. The weights and lengths of the duodenum, jejunum and colon were measured. Approximately 1 cm specimen was taken from each organ, fixed in formalin and stained for histological analysis. Using a light microscopy, the digestive and absorptive properties of the tissues were assessed. Inclusion of A. angustissima leaf meal increased intestinal wall thickness, epithelial thickness, and villus height of the duodenum (P < 0.05). There was no effect on the proportional weight and length of the jejunum, jejunum villi height and villi width (P > 0.05) but jejunum wall thickness decreased with increasing levels of the leaf meal (P < 0.05). Leaf meal inclusion resulted in an increase in weight, intestinal wall and mucosal thickness of the colon (P < 0.05) and a decline in sub-mucosal fold height and haustra coli width of the colon (P < 0.05). Dressed weight was the same across diets at two weeks (P > 0.05). At four and six weeks, broilers on the control and 5% diet had superior dressed weights to the 10% fed broilers (P < 0.05). It was concluded that for intestinal physiological adaptation that will not compromise weight gain in broilers, up to 5% A. angustissima could be included in broiler diets.

“…In this context, it was reported that the higher consumption of diet rich in grains and vegetables decreases the incidence of CRC. This effect involves different mechanisms such as the diminution in the fecal transit time due to the increase in the stool bulk, and consequently, it reduces the contact of carcinogen with colon cells and the fermentation of these fibers of colonic components [14,32]. In addition, significant reduction in concentration of acetate, propionate, and butyrate with increase in fecal pH [33] and the decrease in the number of obligate anaerobe microorganisms have been reported in individuals with colon cancer [34] when compared with healthy people.…”

Many diseases that affect the gastrointestinal tract (GIT) have great influence on the quality of life of the majority of patients. Many probiotic strains are being highly studied as a promising candidate due to their beneficial effect reported in the GIT. With the purpose of increasing the beneficial characteristics of some probiotics strains and, consequently, to improve further the reported results, many probiotic strains expressing or encoding different proteins, with anti-inflammatory activities, have been developed. These recombinant strains have been reported as good candidates for the treatment of different pathological conditions, especially colitis and mucositis disease since they have been shown to have positive results and good perspectives for GIT inflammation. Thus, this chapter will first address the aspects of the gastrointestinal tract in humans as well as its microbiota. In a second moment, it will discuss about chronic diseases, mainly the intestinal ones. Finally, it will discuss about probiotics, especially concerning on lactic acid bacteria (LAB), and its action in the prevention and treatment of these diseases. At the final part, we will point out aspects on the development of recombinant strains and the results found in the literature on disease models.

“…The role of dietary fibre in the body is physiological one and not chemical one, due their functional properties and their effect on the gastrointestinal tract (GI) which improves the gut motility, but also on chemical and bacteriological changes that occur in the intestine (Brownlee et al, 2006;Burkitt et al, 1974). There are two ways in which dietary fiber favors the gut motility; first is their capacity to hold water which contribute to fecal bulk, increamenting stool mass and therefore intestinal luminal bulk due to water retention of dietary fiber increasing persitalsis (Dello Staffolo et al, 2012).…”

INTRODUCTIONObesity is defined, in general terms, as physical manifestation of anormal fat accumulation that alters health and increases mortality. Nowdays, this condition is recognized as a prevalent metabolic disease that has reached epidemic proportions in both developed and developing countries, affecting adults, adolescents and children (Tsigos et al., 2008). According to the World Health Organization (WHO, 2016), in 2014, 39% of adults aged 18+ were overweight (BMI ≥ 25 kg/m2) (39% men and 40% of women). In 2014, 39% of adults aged 18+ were overweight (BMI ≥ 25 kg/m2) (39% of men and 40% of women) and 13% were obese (BMI ≥30 kg/m2) (11% of men and 15% of women). Thus, nearly 2 billion adults worldwide are overweight and, of these, more than half a billion are obese.There are factors that have influenced on the increase of obesity around the world and time, demographics changes since mid-twentieth century where abouth 80 % of the population live in urban ares, which has favored a change in life style, incluiding eating habits exchanging fresh fruits and vegetables for foods with high levels of cholesterol, saturated fats, starch, sugars, sodium, among others, increasing nutrition related chronic diseases such as metabolic syndrome, obesity and diabetes (Fausto-Guerra et al., 2006), and most of these elections are an unconscious behavior, a voluntary food consumption made by the population.On the other side, evidence suggests that balance in food intake and energy consumption is controlled by a biological system. There are chemical molecules with functional properties involved in the equilibrium of energy consumption, thus reducing risk of obesity and among these compounds are dietary fibers (Howarth et al., 2001). Galisteo and Zarzuelo (2008) reported that several studies in humans and experimental models demonstrate efficiency of dietary fiber on regulation of body weight, food consumption, glucose homeostasis, insulin quality and risk factors for cardiovascular disease such as lipids profile, hypertension and systemic inflammatory markers. For this Nowdays, obesity is considered a health problem worldwide which predisposes to development of various metabolic diseases such as type 2 diabetes, cardiovascular disease and cancer among others, as well as, psychological disorders as depression. This condition has been increased through the time because of changes in lifestyle and modification in feeding type. This review provides an update of recent studies about obesity consequences on health and how a healthy diet, including dietary fiber, can helps to keep a healthy body weight and avoiding several diseases related to this condition. Several studies have reported that a healthy and balanced diet helps to control human weight, added to this, a diet rich in dietary fiber (from natural sources or produced biotechnologically) helps to keep a body weight regulation, control of lipid and triglycerides levels because of its chemical, physical and biochemical features. One of the these features is hormonal regulati...
