Dietary fiber or roughage is the indigestible portion of vegetable-based food of our diet. While fibers do not contribute to any energy or nutrients, they do form an important part of the human intake, and lack of dietary fibers in one’s food can lead to several serious health implications ranging from constipation to diverticulitis or even colon cancer.

A diet rich in fibers provides several benefits such as:

It helps keep blood sugar levels in restraint by slowing down the release of glucose into the blood stream.

Certain forms of dietary fibers reduce plasma cholesterol and triglyceride levels.

Due to the water holding capacity, a fiber rich diet is more filling.

Geothermal energy refers to the heat that dissipates from the core of the earth, in the form of active volcanoes, hot water springs, and natural geysers. Like all forms of heat, the geothermal energy can also be converted into electricity. Several countries have developed geothermal power plants. The energy however is not tapped from active volcanoes or such dangerous areas. Rather wells similar to petroleum wells are drilled, and hot ground water is pumped out onto the generators to produce electricity. In places without groundwater, surface water is sprayed onto the hot rocks and the heated water, and steam is later pumped out. Geothermal is a clean and renewable energy source.
