Read the passage given below and answer the questions that follow:
The term dietary fibres refers collectively to indigestible carbohydrates present in plant foods. The importance of these dietary fibres came into the picture when it was observed that the people having diet rich in these fibres, had low incidence of coronary heart disease, irritable bowel syndrome, dental caries and gall stones.
The foodstuffs rich in these dietary fibres are cereals and grains, legumes, fruits with seeds, citrus fruits, carrots, cabbage, green leafy vegetables, apples, melons, peaches, pears etc.
These dietary fibres are not digested by the enzymes of the stomach and the small intestine whereas most of other carbohydrates like starch and sugar are digested and absorbed. The dietary fibres have the property of holding water and because of it, these get swollen and behave like a sponge as these pass through the gastrointestinal tract. The fibres add bulk to the diet and increase transit time in the gut. Some of these fibres may undergo fermentation in the colon.
In recent years, it has been considered essential to have some amount of fibres in the diet. Their beneficial effects lie in preventing coronary heart disease, and decreasing cholesterol level. The fibres like gums and pectin are reported to decrease postprandial (after meals) glucose level in blood. These types of dietary fibres are recommended for the management of certain types of diabetes. Recent studies have shown that the fenugreek (Methi) seeds, which contain 40 per cent gum, are effective in decreasing blood glucose and cholesterol levels as compared to other gum containing vegetables.
Some dietary fibres increase transit time and decrease the time of release of ingested food in colon. The diet having less fibres is associated with colon cancer and the dietary fibres may play a role in decreasing the risk of it.
The dietary fibres hold water so that stools are soft, bulky and readily eliminated. Therefore high fibre intake prevents or relieves constipation.
The fibres increase motility of the small intestine and the colon and by decreasing the transit time there is less time for exposure of the mucosa to harmful toxic substances. Therefore, there is a less desire to eat and the energy intake can be maintained within the range of requirement. This phenomenon helps in keeping a check on obesity. Another reason in helping to decrease obesity is that the high-fibre diets have somewhat lower coefficients of digestibility.
The dietary fibres may have some adverse effects on nutrition by binding some trace metals like calcium, magnesium, phosphorus, zinc and others and therefore preventing their proper absorption. This may pose a possibility of nutritional deficiency especially when diets contain marginal levels of mineral elements. This may become important constraints on increasing dietary fibres. It is suggested that an intake of 40 grams dietary fibres per day is desirable.

BUNGEE-JUMPING
Bungee jumping is an activity that involves jumping from a tall structure while connected to a long elastic cord. The tall structure is usually a fixed object, such as a building, bridge or crane; but it is also possible to jump from a movable object, such as a hot-air-balloon or helicopter, that has the ability to hover above the ground. The thrill comes from the freefalling and the rebound. When the person jumps, the cord stretches, and the jumper flies upwards again as the cord recoils and continues to oscillate up and down until all the kinetic energy is dissipated.
Jumping Heights, located in Mohan Chatti village, in Rishikesh has been rated as one of the most preferred bungee jumping destinations in India at a height of 83 meters. It is the only place in India where bungee jumping can be done from a fixed platform. This is also India’s only fixed platform Bungee- performed from a professional cantilever, to separate it from entertainment parks, and create instead, an extreme adventure zone. The Bungee has been designed by David Allardice of New Zealand.
The Cantilever platform is built over a rocky cliff over-looking the river Hall, a tributary of River Ganges. Bungee-ing amidst the vastness of nature lends the experience an absolutely breathtaking quality. Jumping heights is well known for its safety measures and experienced staff. It costs around Rs 2500 per jump, a bit expensive, but totally worth the experience. The Bungee jumping experience has been set amidst the astoundingly stunning landscape of Rishikesh. To Bungee jump, one must be at least 12 years and should weigh between 40-110 kg.
