A PlOS One study notes drinking coffee (aka moderate caffeine intake) doesn't necessarily lead to hydration. They note coffee has hydrating qualities akin to water. Further empirical studies found no substantial fluid loss in caffeinated beverages. EDIT: Make note we're talking normal doses and moderate intake, though source 2 goes into diminishing effect ...

I think that Carl Sagan said it best: The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff. The current view of cosmology is that every atom that isn't hydrogen, helium, or lithium was created in the fusion furnace in the hearts ...

To start, it is necessary to know the number of bacteria in a defined amount of yoghurt. There are scientific publications on this topic, but the numbers in fresh produced yoghurt are in the area ...

Salt will cause high blood pressure, but only under certain circumstance. physiologic hormonal compensations for increased blood volume: Atrial natriuretic peptide -- increases sodium excretion, hence this is increased with high blood volume Antidiuretic horomone -- ADH increases water reabsorption in the kidney, hence this will be decreased with high ...

As salt accumulates in thebody, it also indirectly increases the extracellular fluid volume for two basic reasons: 1. When there is excess salt in the extracellular fluid,the osmolality of the fluid increases, and this in turn stimulates the thirst center in the brain, making the person drink extra amounts of water to return the extracellular salt ...

Preamble This is a very interesting question one which I don't immediately know an answer to. I think this overly succinct answer and the fact nobody else has answered highlights the degree to which the age old darwinian assumptions play a role in the field. Zoological POV I'm not an expert in this area so I went to a zoology lab technician and this is ...
