This blog was the one I meant to write last week … but it didn’t get written as home events took over.. that blog started with watching the first of the new series of ‘Trust me, I’m a Doctor’ on BBC 2 (not to be confused with Trust me, I’m THE Dr’ as in Dr Who)
This is the second series and I quite enjoy these programmes as I nearly always learn something I didn’t know – and as I try to keep up-to-date with things on the nutritional front I do spend a lot of my time saying to the TV, ‘yes, about time too’, as popular nutrition catches up with what has been going on in science for quite a while. The programme is headed-up by Michael Mosley (of the ‘5/2 fast diet’) drawn from his previous programmes and ‘fast exercise’ – ditto)
I say I enjoy them.. I do, that is, apart from its ‘bitty’ approach where the team investigate about 4 different lines of scientific health issues at the same time (meaning that we start with one idea – move on to the next and the next .. and then pop back to see how the first is going along , than catch up with the second etc. etc.) At least they do not do the exhaustive re-cap each time… but it is annoying when it really doesn’t have to be. I want to say that I am sure we can cope with quarter of an hour on one health issue at a time… followed by the other three … and I’m sure that if we are watching this type of pr0gramme we will wait through the one that may not be immediately relevant to our own situation to learn something on the way. (OK .. rant over)
Now you may know, if you’ve been following this blog for a long time, that I managed to lose quite a bit of weight by doing weights exercises, designed by one of my sons, for less than fifteen minutes a day, while continuing to eat in a low carb (not no carb) way(as I had done for years before menopause caused weight-gain) If I eat pasta, bread,rice or potatoes I eat a limited amount – and I always go for the ‘brown’ wholegrain versions as this gives better nutrition, more fibre and uses more energy to digest.
The nutritional scientist on ‘Trust Me…’ carried out a small on screen test of just 10 people. She knew what she was expecting with the first two trials in her experiment – but she’d also thrown in a third variation she’d not tested before.
Eat pasta and very soon you’ll have an insulin spike in your blood. Now this is natural as pasta is a carbohydrate and that is only a simple digestive step away from being a sugar… and to deal with sugar your body pumps out insulin. Fine so far… only problem is that this spike is followed by a dip in that the insulin is running around your body looking for the sugar to deal with (even after its finished with the stuff you ate). This makes you feel hungry again; gives you the ‘munchies’. It is far better for you if you can keep you insulin stable and low, not such a spike, less of a dip. Keeping your insulin levels steady is key to managing your weight and your long-term health.
The experiment: #1, eat hot freshly cooked pasta – wait – measure insulin in blood. #2 eat cooked and then cooled pasta – wait – measure insulin in blood #3 eat cooked, cooled and kept until the next day and reheated pasta – wait – measure insulin in blood.
Results: #1 – high insulin spike #2 lower insulin level (but who wants to eat cold pasta anyway?) #3 EVEN lower insulin levels! – and that surprised even the tester. When Michael pointed out that 10 people were not much of a statistical sample, she agreed, but then added … but it was ALL 10 of them!
For the scientific details of the how and why, watch the programme – on iPlayer for 2 more weeks here: Trust me I’m a Doctor s2 – 1:
Only problem is – when I do pasta it is usually because I am running out of time and need a fast carb to complete a meal!
However, maybe, I’ll get my act together early enough to cook, cool and reheat my pasta, as, you see … some things ARE better put off until tomorrow 🙂
What’s your take on Pasta? Would you eat re-heated pasta if it was better for you?
What is your favourite pasta based meal?
Look forward to hearing from you
