Home' Trinidad and Tobago Guardian : May 25th 2015 Contents Do you want to eat healthier, but
find you re having a tough time
cleaning up your eating habits? Your
family may not be on board, and
your co-workers generally care
about you when they bring their
pizza or roti or doubles to work.
Eating healthier doesn t have to be
overwhelming. If you want to adopt
healthy habits that will last, then the
easiest way to do it is by making
small, gradual changes.
Don t expect too much from your-
self too soon---it takes about a month
for any new action to become habit.
Before you start making any
changes to your diet, take a week or
two to observe your current eating
Track everything you eat. Keeping
a food journal will open your eyes---
realising that you ate 26 cookies dur-
ing the week, or four fried chicken
dinners, or a starchy pelau that could
easily feed two people in one sitting,
might make you think twice.
You might not realise how bad your
eating habits are until you see an
unhealthy pattern right. Here are
some simple tips to get you started
on the healthy eating path.
• Cook your food at home. If you
typically buy processed food and eat
out regularly, the money you spend
on these unhealthy eating choices
could be used instead to buy healthier
foods. So, ditch the boxed meals and
start cooking from scratch.
• Buy in season, and eat local. All
produce, when bought in season, is
generally cheaper. Produce from your
local farmers is often better than
• Avoid food with pesticides. If
you don t know, check it out. Many
of your apparently healthy veggies
may in fact be tainted with uncon-
• Plan your meals. This will save
you time and money. Planning your
meals in advance stretches your dol-
lars and limits the desire to quickly
grab something on the way home
• Grow your own food. Depending
on where you live, you can grow just
about anything. You can join your
local garden club for tips. Or check
out the Ministry of Food Production.
The Extension, Training and Infor-
mation Services (ETIS) Division of
the Ministry of Food Production
offers low cost and sometimes free
courses on aspects of agriculture at
the Farmer s Training Centre in Cen-
teno and at selected county offices.

A man has been able to control a
robotic limb with a mind-reading chip
implanted in his brain.
It allowed Erik Sorto, from California,
to sip a drink unaided for the first time
in ten years.
The details, published in Science,
reveal how complex bursts of electrical
signals in his brain could be interpreted
into commands for the arm.
Experts said the results made brain-
controlled robotics closer to being a
reality. Sorto was shot at the age of 21.
The damage to his spinal cord left
him paralysed from the neck down.
Two tiny sensors were implanted
into his brain to monitor the activity
of around 100 neurons.
Previous attempts at thought-con-
trolled robotics have focused on the
motor cortex---the region responsible
for the action of individual muscles.
However, the US team tried implant-
ing the chips in the posterior parietal
cortex---the part of the brain that comes
up with the initial intention.
It is the difference between deciding
to pick up a mug or telling your hand
to move towards it. The team hopes
this approach will be more intuitive.
One of the researchers, Prof Richard
Andersen from Caltech, told the BBC
News website: "The first time he tried
the robotic limb he could form his hand
to mirror one of the student s hands
as if shaking hands---for him it was a
He has improved with training so
that he can lift a drink to his mouth
and also control a cursor on a computer
Sorto said: "I joke around with the
guys that I want to be able to drink my
own beer, to be able to take a drink at
my own pace, when I want to take a
sip out of my beer and to not have to
ask somebody to give it to me.
"I really miss that independence. I
think that if it were safe enough, I
would really enjoy grooming myself---
shaving, brushing my own teeth. That
would be fantastic."
A commentary, from researchers Dr
Andrew Pruszynski and Dr Jorn
Diedrichsen, argued: "The results rep-
resent one more step toward making
brain control of a robotic limb or com-
puting device a reality.
"Despite the impressive series of
steps taken over the past 15 years, how-
ever, these neural prosthetic devices
still have a substantial way to go before
becoming practical therapeutic inter-
