You’ve been lied to – we all have – and it’s a big FAT one!!

They lied.

They lied big time.

I’ve written about this earlier – about the reporting only of data that supported a faulty hypothesis and the deliberate ignoring of contrary info.

Watch the vid – it explaines all:

You have every right to be angry…

See you next week.

Food impact on cholesterol is irrelevant

Welcome Back

Here is another important post from Dr Briffa – enjoy!!

Claims regarding the impact of foods on cholesterol are simply irrelevant

I got a press release today from the consumer advocacy group Which? informing me that “Misleading health claims to be banned at last”.

Apparently, European Union Member States today voted to adopt a list of scientifically proven health claims that can be made about food and drink products. Claims for green tea and glucosamine (regarding benefits for blood pressure and joint health) are examples of a couple of things that did not make the cut. On the other hand, it seems the following claims will be allowed to be made:

  • reduced consumption of saturated fat contributes to the maintenance of normal blood cholesterol levels
  • plant sterols and plant stanols contribute to the maintenance of normal blood cholesterol

Cholesterol levels are widely recognised as a marker for heart disease, and so the logic goes that reducing cholesterol levels will help prevent this condition. In this case, cholesterol is being used as what is known as a ‘surrogate marker’. The assumption is that a positive change in surrogate marker levels will translate into benefits for health.

However, is this actually true?

Taking dietary steps to reduce cholesterol has not been convincingly shown to reduce the risk of heart disease or overall risk of death. If this practice does not have benefits for health or extend life, why bother? Eating less saturated fat and swallowing stanols and sterols can reduce cholesterol all they like, but none of it has proven benefits for health.

It is perhaps worthy of note that a PR representative of the Unilever-made Flora Proactiv products commented here [1] that:

“We absolutely agree that simply lowering cholesterol without making wider positive changes to one’s diet and lifestyle will not make a significant positive health impact.”

I take this as admission of the general uselessness of cholesterol reduction in terms of its impact on health.

It can be hard for some to make sense that taking dietary steps to reduce cholesterol is not broadly beneficial to health. However, we should perhaps not be too surprised, when we consider that we have plenty of similar experiences regarding pharmaceutical drugs.

For example:

  1. drugs called resins reduce cholesterol but do not reduce overall risk of death
  2. the drug ezetimibe reduces cholesterol but has never been shown to benefit health
  3. drugs called fibrates improve the ratio of ‘good’ and ‘bad’ cholesterol but don’t reduce overall mortality
  4. hormone replacement therapy improves the ratio of ‘good’ and ‘bad’ cholesterol but doesn’t reduce overall mortality and increases the risk of cardiovascular disease

The situation with statin drugs is somewhat nuanced. In primary prevention (in essentially healthy individuals) statins do not reduce risk of death. In secondary prevention (those who have already had, say, a heart attack or stroke), they do, but the fact remains that even in high risk individuals, the great majority of people who take statins do not stand to benefit from them at all. There is reason to believe, by the way, that the little benefit statins have is not as a result of their cholesterol-reducing action, but due to other effects including anti-inflammatory blood-thinning actions.

In short, the fact that foods low in saturated fat and/or rich in sterols/stanols may contribute to lowered cholesterol levels is irrelevant. The idea that this translates into benefits for health is simply unproven. My advice? Don’t swallow it.

Low-carbohydrate diets look good for the prevention and treatment of cancer

Welcome back:

This week I am presenting 2 posts from the UK. Dr John Briffa (www.Drbriffa.com) is one of the few medicos on-line that are wroth following and I thought that these 2 posts of his are well worth passing on for you to read.

Enjoy.

Low-carbohydrate diets look good for the prevention and treatment of cancer

Posted on 29 November 2011

In general terms, I recommend a diet lower in carbohydrate than conventional guidelines say is healthy. At least part of my thinking is based on abundant evidence linking a relatively carbohydrate controlled diet with benefits in terms of body weight and disease markers for conditions such as heart disease and type 2 diabetes. However, I came across a recent paper which made me think more about the impact a low-carbohydrate might have on risk of another important condition – cancer [1].

You can read a summary of the paper here and download a provisional pdf of the full paper here.

The paper starts with reference to hunter-gatherer diets, and their relatively protein-rich, low-carb nature, and remarks that cancer has been found to be rare in societies eating such a diet. It then goes on to postulate several major mechanisms that may account for this association. These include:

1. Cancer cells feed preferentially on sugar (glucose)
Glucose (from sugary and starchy foods) provides the prime fuel for cancer cells, so a diet lower in carbohydrate may therefore reduce tumour development or progression.

2. Insulin and IGF-1 can stimulate tumour cell growth
High carbohydrate diets increase levels of insulin and what is known as insulin-like growth factor-1 (IGF-1) which stimulate tumour cell growth. A lower carbohydrate diet may reduce tumour proliferation as a result.

3. Ketones suppress cancer
Very low carbohydrate diets can lead to the production of ‘ketones’ (mainly produced from fat) that suppress tumours.

4. Low-carbohydrate and ‘ketogenic’ diets ‘starve’ cancer
Low-carbohydrate diets mimic caloric restriction and ketogenic diets mimic starvation – and caloric restriction/starvation is linked to reduce tumour development and progression.

5. Low carbohydrate diets can reduce inflammation
Inflammation is believed to be a risk factor in the development of cancer, and high-carb diets encourage inflammation. Low-carbohydrate diets have been found to be more effective than low-fat ones in terms of reducing markers of inflammation.

The paper also makes the case that such diets may help better meet the nutritional needs of those with cancer.

I’ve only plucked out some of the highlights of this paper, as you can read it in its entirety if you so wish. If you do, though, you may well find that the paper makes a pretty compelling case for the role of carbohydrate-restricted diets in the prevention and treatment of cancer.

Questions raised over the role of HDL-cholesterol in cardiovascular disease

Posted on 2 December 2011

Cholesterol in the bloodstream is transported in two main forms: ‘low-density lipoprotein-cholesterol’ (LDL-cholesterol) and ‘high-density lipoprotein-cholesterol’ (HDL-cholesterol). Conventional wisdom tells us that LDL-cholesterol is responsible for the fatty build-up on the inside of arteries known as ‘atherosclerotic plaque’, but that HDL-cholesterol clears this plaque. Because of this, HDL- and LDL-cholesterols are dubbed ‘good’ and ‘bad’ cholesterol respectively.

A paper was published recently which attempted to explore further the relationship between HDL-cholesterol and risk of cardiovascular disease. Low levels of HDL-cholesterol have been associated with enhanced risk. But just because two things are associated with each other, does not mean one is causing the other.

Low HDL-cholesterol levels often go hand-in-hand with other metabolic ‘abnormalities’ including raised triglyceride (a form of blood fat) levels, raised blood pressure, raised blood sugar levels and abdominal obesity. Could it be one or more of these associated factors or other factors entirely that account for the relationship between low HDL-cholesterol levels and heightened risk of cardiovascular disease.

To answer this question, Danish scientists isolated individuals with low HDL-cholesterol levels as a result of a genetic glitch [1]. In these individuals, HDL-cholesterol levels are low, but this is usually in isolation and not in combination with other metabolic abnormalities (such as raised triglycerides, blood pressure, blood sugar and abdominal obesity).

It turns out that in these individuals with genetically determined low HDL-cholesterol levels, risk of heart attack is no higher than in the general population. The logical conclusion here is that low HDL-cholesterol does not cause heart attacks (which means that higher levels do not protect against it either). In other words, this evidence strongly suggests the link between HDL-cholesterol levels and cardiovascular disease risk is only an association and not causal.

But if this is the case, could the same not be true for LDL-cholesterol too?

Many doctors and scientists will not hear of such a thing, of course, and will quote studies which show cholesterol-reduction with statin drugs reduces risk of cardiovascular disease as evidence of the fact LDL-cholesterol causes heart disease. However, as is well-recognised now, statins have many actions in the body which might reduce cardiovascular disease risk in a way which has nothing to do with cholesterol (including anti-inflammatory and blood-thinning properties).

Also, we have evidence that statins substantially reduce the risk of stroke, even though cholesterol is a weak or non-existent risk factor for stroke. And we have evidence that statins reduce the risk of cardiovascular disease in individuals with normal or even low levels of cholesterol. These lines of evidence suggest that statins actually work through mechanisms that are distinct from their cholesterol-reducing properties.

I know that some will tell us that cholesterol is to be found in atherosclerotic plaque and that ‘proves’ that cholesterol causes cardiovascular disease. Actually, though, it does nothing of the sort. If I graze my knee and form a scab there, chemical analysis of the scab will reveal something called fibrin (a clotting agent). Has fibrin caused my scab? Of course not.

30 Something Reasons to Get in Shape for 30 Something+ Year Olds……

Hi & Welcome back!!

I have put together a list of what I believe are the most compelling reasons for the over 30’s (not to mention over 40’s or my mob – the over 50’s) to get in shape and stay there.

In shape - but not for most of us mere mortals

Being in shape for me means that I have a low & age appropriate body Fat %, I feel strong and have muscular endurance, that I hold a reasonable cardio endurance, can touch my toes and have a good general flexibility. It is my firm belief that getting better in the these areas will see you able to live and enjoy a fuller life. (You’ll also LBN!!)

So to get or to stay in great shape her are 30 something reasons…

LBN

Let’s clear up LBN – LBN means Look Better Naked. With a lower fat percentage, some muscle and more importantly the confidence that comes with being in shape you can’t help but LBN!

Reduces Cholesterol

Increasing research is showing that this is not the bad boy it has been painted as for the last few decades, but nonetheless too much LDL (Low Density Lipoproteins) is still not a good thing to have going on and regular exercise (especially Interval style – see earlier posts) has been proven to reduce LDL levels whilst increasing HDL ( High Density Lipoproteins) – the good cholesterol.

Not everyone can get in this shape - but we can improve our own!!

You’ll Sleep Better

Lack of sleep increases the release of cortisol and cortisol promotes fat storage especially around your belly. ( no cortisol is not bad – but too much of it is!) Regular challenging exercise helps you get to sleep quicker and to sleep longer and more deeply. It also reduces the release of stress related hormones like cortisol and promotes the release of HGH ( Human growth Hormone) This hormone is often called the ‘Fountain of Youth’ hormone due to its effect on your body’s fat stores ( it cuts them) your lean tissue (you get more muscular) and your over all health.

You’ll feel better about yourself

Just working out regularly and getting in shape makes you feel better about yourself. We can’t all look like Brad Pitt in Troy or Angelina in… (Well ladies insert your favourite here!) but we CAN make of ourselves the best we can. Doing this enables to feel more in control of our lives and being in shape for ourselves will give a confidence boost.

Physical appearance isn’t everything,  but by getting into better shape you’ll look better, and this will improve your confidence.

Your Blood Pressure will reduce

Stress, lack of sleep, poor diet – all contribute to high blood pressure – a recognised killer. Getting in shape not only reduces your blood pressure but can actually prevent it from either re-occurring or taking place in the first place!

Your won’t ache or hurt as much

One of the most common (and in many cases debilitating) complaints of the over 30’s ( & it sharply increases for each 5 year increment above this in the general population) is back pain – usually lower back pain. Years of sitting actually shortens certain muscles & tendons resulting in constant & additional pressure on our lumbar region. General lack of movement and no weight bearing exercise weaken muscles generally. This combines to the dreaded ‘throwing your back out’…

You won't need one of these if you are in shape...

Simply by lifting weights, moving more and sitting less can & does reduce this. Getting in shape with the strength & flexibility can eradicate it completely or at lest reduce it to more manageable levels. A large number of studies show that exercise is an effective treatment for recurrent low back pain.

You’ll suffer fewer injuries

Getting in shape & developing a strong, fit body will see your injury numbers decline severely. Not just back pain, but twisted ankles, stubbed toes, sore shoulders and neck pain – but general aches & pains all decrease the fitter and more in shape that you are.

You’ll be able to stand in the one spot longer (important in supermarkets, cinemas, at parades, in Church or just life in general…

You’ll reduce your chances of getting some types of Cancer

There are a number of studies that show regular exercise and low body fat equal a lesser chance of developing a number of cancers – particularly bowel, colon and breast cancers. In some cases the studies suggest being in shape & regularly exercising reduces some cancer risks by up to 40%.

You’ll have a faster Metabolism (my favourite)

By now you know that this blog is primarily about ways to recondition your metabolism so you shed fat, get fitter and enjoy much better health. I’m not going to labour the point here – by getting in shape will recondition your metabolism meaning that you heal faster and burn calories more efficiently & effectively. A faster metabolism carries a host of health benefits.

You’ll recapture some ‘lost’ Range of Motion

Getting in shape & working out with a strategic program will help you rediscover the joys of being able to

Range of motion - not everyone wants this much, but you can get more...

touch your toes, scratch your back and other many other  lost ranges of motion.

Nowhere else is it truer that if you don’t move it you’ll lose it as in the area of flexibility.

Becoming more flexible reduces joint stiffness, can assist with arthritis pain and also adds to reducing injury occurrence.

Your Functional Strength will improve

Functional strength is one of those terms that has become more of a marketing handle than a real descriptor of a real thing. However true functional strength means that you have the strength & power to do the things you need to each day in your life.

It can be carrying groceries, lifting a child, getting out of a chair, digging a garden bed, riding a bike, painting a ceiling, push starting a car or… you get the idea.

Being in shape improves your quality of life because you have the ability to do the things in your life.

You’ll improve your Insulin Sensitivity

Insulin sensitivity is the degree to which your body (primarily muscles) is able to receive and glucose from your bloodstream. Insulin resistance means that more & more insulin has to be released by the pancreas leading to increased fat storage, or in extreme cases (which are becoming less rare in these days of obesity) a loss of the ability to produce sufficient insulin at all. Yep – dose dependent diabetes…

Being in shape with a more efficient metabolism & lower body fat improves insulin sensitivity and can prevent the development of type 2 (often called adult onset) diabetes.

You can find a few out of the 168 hours each week to get in shape

With 168 hours each and every week we can all find 3 or 4 of these to use to get in and stay in shape. The benefits are too many to ignore and the results too important to miss out on because ‘Dancing with the Stars’ is on.

If you have to, make your workouts an appointment in a diary. Just find the time…

You’ll have a higher desire for Sex

No not enough that you’ll develop sex addiction, but being in shape & LBN certainly raises the sex drive of both males & females.

Part of it is better circulation, part of it is increased body awareness and feeling more in control of your body and a large part of it is improved hormone health. Regardless – getting or being in shape certainly improves the bedroom…

Heart Atack and more diseases either in progress or about to start...

You’ll Decrease your Risk of Heart Disease

Challenging exercise exercises the heart like any other muscle and like any other muscle regular exercise improves the hearts strength & responsiveness to the demands placed on it.

Contractile strength improves and with higher HDL & lower LDL your risk of heart disease drops. A lot.

You’ll get a kick out of exercise

Challenging exercise releases a number of ‘feel good’ hormones (think runners high) that elevate our mood, lift depression, decrease the effects of stress and poor sleep and have been proven to make us happier.

This effect is even more marked when you make at least a part of your exercise program an activity that you love to do. It can be ballroom dancing, squash, tennis, a martial art, yoga – whatever. When you have at least 1 regular activity of your exercise program as something you love you overall enjoy getting & staying in shape more. And you smile more – a lot more.

You’ll likely live longer

Folk who are in shape tend to live longer, have better health and less disease & injury. At the very least they experience a better quality of life.

You’ll develop (rediscover) better balance and Coordination

This sort of ties in with suffering less injuries if you are fit – but if you are in shape & working out regularly your kinaesthetic awareness (your mental awareness of your body’s place in the space around it) improves. You’ll trip less often, bump into less and find that you drop things less often.

Well maybe not this much more balance (unless you want to work for it!!)

Even better – for the older ones of us – you’ll be less likely to fall – and for anyone in their late 50’s on falls is a major health problem …

You’ll reduce your chance of Osteoarthritis

Weight bearing exercise coupled with moving more means stronger bones. Period. Calcium supplements have their place and so does diet but if you want strong bones move some weight and get stronger than you are today.

Your gut will work better

Getting in shape means more efficient processing of the food you eat. It means reduced risk of ‘over 40’s’ diseases such as diverticulitis, gastrointestinal haemorrhage, and inflammatory bowel disease; for everyone else it means a decreased incidence of constipation.

Getting in shape is not just for cosmetic external purposes – a reconditioned metabolism means everything works better.

Your weight will change

Getting in shape means dropping body fat and developing some muscle. Scales don’t count because muscle weighs more than fat, but the mirror, your partner’s reactions and how your clothes fit do.

Your body will use more fat as fuel

Regular exercise tends to improve your body’s ability to use fat as fuel. This is a good thing as is unfit folk our bodies have a tendency to store fat and breakdown muscle for fuel once glucose is depleted.

Even better – unhealthy fat stores like belly rolls and love handles, visceral (internal) fat can not only be prevented but heavily reduced if not wiped out by getting in shape.

You’ll get sick less often

Your entire Immune System will improve...

Being fit means a stronger immune systems and this translates into less illness – fewer colds, quicker recovery from the ‘flu and generally better health.

You’ll focus better

Another truth about moving into the above 30 age bracket – our ability to focus , concentrate and multitask begins to drop. A lot. By your 50’s it can be beginning to become a real issue.

A better supply of oxygen & nutrients to the brain due to improved circulation from regular exercise not only arrests this mental decline, but can on occasion reverse it.

You’ll have loads more energy

Exercising regularly improves your body’s utilisation of food and the performance of its various energy systems. Net result? A real increase in energy levels.

More energy means better quality of life and more engagement in living – to good to miss!!

You’ll reduce the chance of developing Alzheimer’s

Remeber when you had this much energy??!!

Although this is likely tied to improved circulation of oxygen & nutrients to the brain, getting in shape through challenging & regular exercise appears to keep your brain sharper and may reduce the chances of you developing not only Alzheimer’s disease but a number of other dementia type mental disorders.

It may be tied to the improved circulation and the increased amount of mental awareness required to partake of exercise or other physical activities. There is even some talk of the feel good hormones also playing a role…

In any case the research is ongoing but is too good to ignore.

You’ll feel like you are reaching your potential

Being out of shape, fat, flabby and out o breath with no strength means that you cannot possibly be at your best. The world is a nastier place when you are out of shape and your internal landscape can come to resemble your outer one. Not healthy – physically or mentally.

By getting in shape, reconditioning your metabolism and losing ft you transform into you Ver 2.0 – a better version of yourself.

The Greeks used to say ‘Healthy body, Healthy mind’ – and the more we learn about how our bodies work and how they integrate with our emotions and thought process the more correct the Greeks seem to be.

Undertaking a physical transformation will improve your mental, emotional, and spiritual state; and upgrade your quality of life.

From the appearance of your skin, to your overall body shape, to how well your metabolism works, how you think or shrug off illness – just about every physical attribute you posses gets better when you’re in shape.

Set them up for a better quality of life

You’ll set a good example for your kids (or grandkids, or…)

By taking charge of your shape & fitness and being committed to it you will also help your kids to develop similar habits. Being in shape has so many health benefits that if you can influence by example your children you could literally be reducing the amount of stress, pain & illnesses that they will suffer in their lives. A helluva a good reason to get & stay in shape as far as I am concerned…
