FRUIT
FOR
YOUR
LABOUR
Pineapple can provide
postrun first aid
WHAT’S ON YOUR POSTRUN recovery
menu? Probably not pineapple, but
you should certainly give it a try.
Studies show its high-glycaemic
carbohydrates kick-start recovery
straight after a heavy session,
replenishing your glycogen stores
and spiking your insulin levels to
deliver much-needed micronutrients
to muscles. And its benefits don’t
stop there. Pineapples also contain
a potent anti-inflammatory enzyme
called bromelain, which tackles
muscle soreness – and research
suggests it also helps immune cells
to clear up tiny muscle fibres that
can break off during exercise.
METAL FATIGUE
Feeling unusually tired after
a run? You may be low in
iron, as many runners are.
Menstruation is a major
factor, which is why women
are at a higher risk than
men, but iron is also lost
through sweat. And levels
of the hormone hepcidin
- which inhibits iron
absorption – tend to spike
after hard workouts. The
key, says new research^2 , is
to eat iron-rich foods (eg
seafood and spinach) in the
hour after an early workout,
as hepcidin levels are low in
the morning.
CHEAT RESISTANT
A ‘cheat day’ is common in
many diets. But if you’re
following the keto diet –
very low carb, high fat –
it’s a bad idea. Research
suggests that just one
75g hit of glucose – the
equivalent to a plate of
chips – while on a keto diet
can damage blood vessels.
Have another avo instead.
