People have believed for years that eating salt makes you gain weight. The working theory behind this was that eating salt made you retain water and made you thirsty, which made you heavier. But a study by Vanderbilt University researchers turns that theory on its head. Salt consumption, it seems, does neither. [1]
It could even help you…lose weight?
Many places on the planet have arid climates and harvest rainwater in order to stay irrigated even when the sun blazes hot. California scientists have taken a hint from those who take the rain when it comes in order to help the state survive one of the worst droughts in its history.
This is no new technology. China recently commemorated a 2000-year old irrigation system. Proper irrigation systems not only save water in times of drought, but also save entire cities from flooding when rivers and lakes overflow.
