How many kJs are you drinking?

We know drinks contain energy (kilojoules) but as liquid is not as filling (and we can happily drink a few), we often don't realise just how much energy we're consuming. Do you know how many kJs you're drinking?

• 'Light' beer refers to the alcohol content which will affect the energy content and note the difference between a low-alcohol beer (100kJ per glass) and a reduced-alcohol beer at (305kJ per glass).

• If you're using mixers, go for the low-kilojoule versions; the spirits give you more than enough by themselves.

• And when you're looking at the table below, remember that a standard glass of wine is defined as 100ml. Measure that out and you may be surprised how small a glass that is. If your glass is bigger; your kJ intake per glass of wine can be much higher.

The drinks below are typical bar measures listed from highest to lowest kilojoules:
