Why those warnings to 'keep hydrated' are hogwash!

You might assume the advice 'carry a bottle of water with you' is directed at intrepid souls about to cross a barren wasteland, or en route to some far-flung place where water is hard to find. But no, it is the warning to commuters from strike-hit Southern rail.
And they aren't the only nanny bossing us to take water with us every time we leave the house. Chivvied by preachy reminders, millions of us are now paranoid about suffering a plague of ills if we don't carry extortionately priced bottles of water at all times.

You see the results of this mania every day in streets, shops, offices and on public transport. Adults are dutifully sipping from plastic bottles with stoppers that resemble baby bottle teats. Since the turn of the millennium, bottled water consumption in the UK has doubled. 

Last year, we each drank an average 44 litres — a total of almost 3.3 billion litres, predicted to grow to 4.8 billion by 2020, and worth £2.5 billion a year to the industry.

Expert reveals why seafood really is a superfood

From avocados and kale, to berries and seeds, the list of superfoods has never been bigger. 
Many of us spend much of our hard-earned cash buying the latest en trend food in a bid to be healthy. But by sticking to dry land, we may be overlooking a number of natural sources with 'super' properties.

From improving complexion to keeping bones and teeth healthy, dietitian Juliette Kellow explains how eating seafood can be key to maintaining good health. She has worked with Seafish, the UK authority on the fishing industry, to put together a definitive top 10 list of ‘superfish’  as well as the ultimate super fish dish. 

It doesn’t appear in our diet very often, but protein and nutrient-rich crab is the ultimate superfish.  In particular, the brown meat is packed with calcium, which is important for bone health.  The brown meat also contains iron for making red blood cells and preventing tiredness.  Both brown and white meat are exceptionally high in copper – a 140g serving white meat provides more than enough (and brown meat even more).

Can supplements really make us more beautiful?

Beauty pills all contain ingredients which are believed to have a positive effect on the skin.
But the 'perfect dosage' can't be agreed upon by experts, and many warn that collagen doesn't work when taken orally.  However, some supplements do help to keep your skin young while there are many that don't work at all.
Here, in a piece for The Hippocratic Post, medical journalist Thea Jourdan reveals what the main pills are to avoid.

The market for OTC anti-ageing 'beauty' nutritional supplements is growing but can you really expect to pop a pill and see the results in the mirror?  All beauty pills contain active ingredients that they say have a positive effect on the skin. 
Ones you may expect to work – like those containing collagen for example – are actually pretty useless when taken by mouth since they don't survive the digestive process. 
Others may surprise you, like those which have lycopene in their ingredients list, which is quite effective.  Experts can't agree perfect dosages and individual response to these supplements is very variable.
