TL;DR: Two properties of the fibre of commonly eaten vegetables and fruit, namely water-holding capacity (w.h.c.) and ion exchange capacity, are described to suggest that in their natural state, bran are better as hydrophilic laxatives than bananas, cauliflower, potatoes and turnip.
Abstract: There is a need to explore physical characteristics of dietary vegetable fibre that can be tested in nutritional studies. This paper describes two properties of the fibre of commonly eaten vegetables and fruit, namely water-holding capacity (w.h.c.) and ion exchange capacity. Twenty-six different fruit and vegetables were dried to a powder. The capacity of the powder to hold water was estimated. Lettuce, carrot, cucumber, celery and aubergine had the greatest w.h.c. whereas maize, oatmeal, potato, banana, wheat and bran had the least. The water-adsorptive capacity of any dietary plant is determined by its fibre content and the water-holding capacity of the fibre. Estimations of the fibre content of the original plant and the w.h.c. of that fibre suggest that in their natural state, bran (447 g of water holding/100 g of original material), mango (312 g), carrot (208 g), apple (177 g) and brussels sprouts (168 g) are better as hydrophilic laxatives than bananas (68 g), cauliflower (68 g), potatoes (49 g) and turnip (37 g). Most of the fibre acts as a monofunctional weak cation exchange resin; lettuce (3.1 mequiv./g), cabbage, carrot, orange, turnip (2.4 mequiv./g) are in the range of commercially available weak cation exchange resin. When a diet is changed to one with a high fibre content then these physical characteristics may influence the choice of vegetables and fruit which are included in the diet.

TL;DR: A robust and reliable method was developed to measure resistant starch (RS), i.e., starch that enters the large intestine, and values obtained were in good agreement with published in vivo data.
Abstract: A robust and reliable method was developed to measure resistant starch (RS), ie, starch that enters the large intestine In vivo conditions were reflected as much as possible while a user-friendly format was maintained Parameters investigated included a-amylase concentration, pH of incubation, maltose inhibition of alpha-amylase, the need for amyloglucosidase inclusion, the effect of shaking and stirring on determined values, and problems in recovering and analyzing the RS-containing pellet The RS values obtained were in good agreement with published in vivo data An interlaboratory evaluation of the method has been completed (First Action Method 200202)

TL;DR: Marine algae appear to be good sources of fibres presenting great chemical, physico-chemical and rheological diversities that may be beneficial in nutrition.
Abstract: The soluble and insoluble dietary fibre contents of seven marine algae (‘sea vegetables’): wakame (Undaria pinnatifida), hijiki (Hijiki fusiformis), sea spaghetti (Himanthalia elongata), arame (Eisenia bicyclis), sea lettuce (Ulva lactuca), A O nori (Enteromorpha spp), and nori (Porphyra tenera) were determined by the gravimetric method of Prosky et al (J Assoc Anal Chem 1988, 71 1017–1023) following some adaptations. These seaweeds are particularly rich in dietary fibres with total dietary fibre contents varying between 32·7 and 74·6% (on a dry weight basis) of which 51·6 to 85·0% are water soluble. Marine algae appear to be good sources of fibres presenting great chemical, physico-chemical and rheological diversities that may be beneficial in nutrition.
