Your health: Hydration and alcohol

Did you know that the body is 70% water? Staying hydrated therefore is very important. Just 1% dehydration can affect how your brain functions. Other symptoms of dehydration include:

Thirst is not a good indicator of dehydration. If you are thirsty, you are already likely to be suffering from the effects of dehydration.

Depending on the weather and your activity levels, the average recommended amount to drink is 6-8 glasses of fluid a day, (approx. 1.2litres). There are many sources which can contribute to your fluid intake. Around 30% comes from your food especially if you eat lots of fruit and vegetables, which have high water content.

Other beverages (drink in moderation):

Alcohol – Know your limits!
Women should not exceed more than 14-21 units of alcohol a week, men’s limit is 21-28 units a week, and it advisable to spread this throughout the week rather than binge drink.
In simple terms, a UK unit is 10ml/8 grams of pure alcohol. The number of units in a drink depends on what you’re drinking.

One Unit is a pub measure of spirits, one-and-a-half units is an alcopop (e.g. Smirnoff Ice, Bacardi Breezer, WKD), while two Units is a pint of ordinary-strength lager, pint of bitter (John Smith’s, Boddingtons), a 175ml glass of red/white wine, or pint of ordinary-strength cider (Dry Blackthorn, Strongbow). Meanwhile, three Units is a pint of strong lager (Stella Artois, Kronenbourg 1664) or a 250ml glass of strong Chardonnay. It takes the body roughly one hour to process one unit of alcohol.

Alcohol also has a calorific value, 1g of alcohol = 7 calories:

That’s why sometimes alcohol is seen as empty calories – it doesn’t have any nutritional benefit in terms of macro-nutrients.
