Fit or Fat?

Does diet/fitness form part of your New Year's Resolutions?

Well, it is the New Year and everyone is talking about fitness. There are many different groups of people. There are those that are very stoically opposed to more exercise, saying that they are not changing anything just because it is 2011. At the other end of the scale, there are those that are jumping into the New Year with gusto, with hundreds of fitness-related resolutions to stick to. In between, are the rest of us, wanting to get more fit and healthy, but trying to make sure that we can actually stick to what we plan (at least for the first few months!!).

 But I read a few interesting articles recently, that showed that both the fitness fanatics or the living room loungers COULD be right. The only problem is the 2 articles contradict each other a bit, as we so often find when reading articles about health – a superfood one week, may be too full of sugar the next….

Anyway, the first article suggests that flabby hips and thighs could help the treatment of a range of illnesses including heart disease, arthritis, motor neurone disease and diabetes.

But when you read a bit further, it is not quite as simple as that. Doctors and scientists want to extract stem cells from our excess fat to keep on hand as a personal body repair kit. And any person of average weight would have enough spare fat to extract the stem cells.

For example, some scientists are carrying out research to convert stem cells from body fat into insulin-producing cells to treat diabetes. The type of stem cells found in fat — mesenchymal stem cells — are already known to be able to develop into bone, fat or cartilage.

Other researchers are working at turning the stem cells in fat into cells to be used in the repair of the liver and to treat central nervous system disorders.

One British doctor has applied for a licence to store stem cells from the fat removed from women undergoing liposuction as a cosmetic procedure. A new stem cell storage company, Precious Cells, has a list of 15 clients waiting to store stem cells from fat removed during cosmetic surgery. Companies that offer families storage of stem cells from their babies’ umbilical cord blood are also now planning to start fat banks.

In Holland, new research by the Erasmus University Medical Centre in Rotterdam found that stem cells taken from fat on a patient’s stomach can safely improve the function of the heart after a heart attack. Results of a small trial of 14 patients, presented at the American Heart Association last month, showed that bloodflow through the heart was 3½ times better for patients who received stem cells from their fat compared with those who received a placebo.

Ok, and what does the second article say? Well, that almost half of women are putting themselves at risk of cancer due to their bulging waistlines. While a common perception is that men carry more weight around their middle, Government figures show 44% of women in England have a large waistline, compared with 32% of men.

Experts from the World Cancer Research Fund (WCRF) recommend that women have a healthy waist measurement of less than 31.5in (80cm) while men keep to less than 37in (94cm). Excess body fat increases the risk of all cancers, but is strongly linked to cancers of the bowel, pancreas, breast and womb lining.  People can measure their waists by putting a tape measure half-way between their lowest rib cage and the hip bone.

Ok so what does this all mean? Well, basically nothing has changed. The same things that we have heard so many times are still true – keeping your weight down to an acceptable level is important for your health. It is just that sometimes we have a part to play i.e. in keeping our waist below certain measurements, but other times science can lend a helping hand – using our own fat cells (and even someone of average weight has them!) to keep us healthy in the future.

 So still something to think about if we are working on those healthy New Year’s resolutions!!

Got a good tan on your holiday?

Wednesday, March 31st, 2010

In the UK, considering the appalling weather that we often experience, a big reason for going on holiday is often to get that elusive tan.  We come home from our beach holiday, relaxed and refreshed, proud to show off our tan and hear the cries of ‘You look well’ from others left languishing in the office!

We all may try to get a tan on holiday, but what if you have this tan all year round

 But if you go brown, even when you have not even been in the sun, you could not be well at all. Genetic haemochromatosis  - also known as primary iron overload – is a condition that causes the body to retain too much iron from the diet.

Iron is a mineral vital to the human body, regulating cell growth and ensuring oxygen flows to the cells, keeping immunity and energy levels high. But like so many things in the body, there is a balance, and too much iron can be toxic. A build up of iron in the brain’s pituitary gland can trigger a classic symptom that gives rise to the conditions other name – bronze diabetes. This is because it can appear as though you have a permanent tan. The reason is that iron overload in the pituitary gland stimulates  an over production of melanin, the pigment that gives our skin its colour.

Undiagnosed iron overload can cause a wide range of health issues, including diabetes, heart disorders, chest and joint pain, liver cirrhosis, pancreatic problems and cancer. A build up of iron in the bones can lead to crystallisation.

It is a common genetic condition. Two genes have been identified that cause it and about 1 in 5000 people in the UK are affected. It is prevalent in all Caucasian populations, but may be slightly higher in those of Irish descent.

The good news is that this disorder is a treatable condition. However, the problem is that because you may look well, the condition can be undiagnosed for years. If you have any of the symptoms, or are getting browner even when you haven’t been on holiday, then just ask your doctor for a simple blood test which can check your iron levels.

 The treatment is very simple – giving blood, as two thirds of the body’s iron lie in the blood. Patients generally give a pint a week until their levels return to normal, and then once every 3 to 6 months. The blood is safe to be used by blood banks,  since people without the faulty gene can rid themselves of the excess iron.

I had heard of this disease before, but didn’t realise that a symptom is a permanent tan. I will think twice before being jealous of people with a year long tan…

Water Water Everywhere, but not a drop to drink…

Tuesday, March 30th, 2010

So you have saved up for that dream holiday and you are finally there. You are travelling in a hot exotic country and have done all your research and planning – so what is one of the cardinal rules? That’s right, carry your own bottled water with you. It can be unhygienic if you don’t have your own sealed bottles – you run a risk of food poisoning –  and you don’t want to get dehydrated….

We all often drink from bottled water on holiday

But how does this rule fit with the latest news that water can be bad for you – triggering weight gain and fertility problems. But this doesn’t make sense does it? When water is the primary content of our cells and the major content of most organisms? In fact, some figures suggest we should drink up to 3 litres of the clear stuff to maintain a healthy lifestyle.

Well, before you really start to panic, it is not actually water as such that is bad for you. It is the pollutants that it is contaminated with, from both the water itself, and the plastic bottle that contains it.

Let’s take the plastic bottle first. Chemicals such as bisphenol A (BPA), used in the manufacture of plastic bottles, have been linked to reproductive difficulties as well as cardiovascular disease and diabetes. A recent study by Harvard School of Public Health found that those who drank from bottles made with BPA showed a 2/3 increase of the chemical in their urine.

And what about the water itself? Well in the UK, oestrogen compounds get into our water supply from pesticides and herbicides that wash off from soil into our rivers. Oestrogen is the  hormone that stimulates female characteristics in woman at puberty. An excessive amount of oestrogen in the body not only drives certain cancers, but affects the way we accumulate fat, So the more we are exposed to oestrogen, the harder it is to lose body fat. And an increase in body fat has been linked to many illnesses including heart disease and cancer.

Well when we are abroad, we may not fill up water from the tap. In fact, we may think we are ok if we use bottled water, but even this is not free from peril. As well as the problems with the plastic itself, when you open bottled water it is no longer sterile and so sits like a stagnant pond attracting bacteria. Before your travels, you might want to purchase an eco product such as the Bottle for Life, a BPA free stainless steel bottle.

Ok, so what next? Well if you ask me, it might be a bit of a headline grabbing story, and probably should not have too much impact while we are on holiday. But it is something you might want to think about…
