We are what
we eat. If this is true then people are healthy because they eat healthy foods
and unhealthy because they eat unhealthy foods. Sounds perfectly reasonable.
Why is it then that every six months we get news bulletins and magazine
articles warning that foods that we used
think were healthy are now deemed to be unhealthy. We were told eggs are
unhealthy, milk was unhealthy and, in extreme cases Vegans warned that meat, and
even fish, in any form are very unhealthy?
We were told that fat is extremely unhealthy. I
watched the ABC Catalyst programme at 8-00pm on Thursday the 24th of
October, and to my very great surprise several respected cardiologists and
medical researchers said that fat was not the cause of heart disease. It is all
very confusing.
When I was a boy my mother gave me healthy and
wholesome food. When I was growing up in the early Post World War 2 years,
dieticians heavily promoted what was called the Oslo Lunch. I guess someone in
Oslo thought of it first. It consisted of lean meat, wholemeal bread, cheese,
milk, eggs, vegetables and fruit. That is basically what we ate, plus a healthy
breakfast of cereal and two eggs on toast. Sometimes the eggs were fried with
bacon or they were poached, scrambled or soft boiled.
My parents also liked lamb’s fry and bacon, kidney,
tripe and brains. I could only handle about two mouthfuls of lamb’s fry before
it became inedible and I could not stomach brains, kidney or tripe at all. My
parents had lived through the depression and firmly believed in the adage
“Waste not, want not”. With poignant comments about the starving children in
Africa, they insisted that their children eat whatever food was put in front of
them, and we did. Except for tripe. To me it was like chewing chopped up
bicycle inner tubes and I was given a family dispensation as far as tripe was
concerned.
But according to the medical wisdom of the 1970s, my loving and caring mother was quietly
killing me. Until I was in my early twenties, I generally ate two eggs a day.
Then some doctors said that eggs were very unhealthy and you should only eat one or two eggs a week. Eggs have very high
cholesterol levels, in fact just one solitary egg contains much more than the recommended
total daily intake of cholesterol. Other doctors said cheese was unhealthy,
milk was unhealthy and butter was very unhealthy. It seemed as if the Oslo
lunch was virtual suicide package.
Since the 1970s we have had more and more
revelations of once healthy foods suddenly being named as harbingers of death.
At the same time health food shops sprang up like mushrooms in shopping centres.
Nobody seemed to be too concerned that a lot of these health foods were heavily
laced with sugar…until sugar was also named as a very unhealthy nutrient.
So then we started using artificial sweeteners
instead of sugar. Eventually, you guessed it, some scientists then warned that
artificial sweeteners were even more unhealthy than sugar. They may not make
you fat like sugar does, but they could make you very dead because they were
carcinogenic.
Over the years other food fads followed in rapid
succession:
Salt
is bad for you: Not true. Salt is essential for life.
You cannot really overdose on salt because any excess is flushed away with your
urine. Of course if you swallowed 500 grams of salt in one go you would die,
that is, if you didn’t vomit it straight up again because, among other things,
salt is an emetic.
Carrots
improve your eyesight. No they don’t. It is believed this
myth was promulgated by the Royal Air Force in World War Two. The British were
using RADAR to detect German planes and they did not want to Germans to know
what they were doing so they put about the story that RAF pilots ate a lot of
carrots which gave them improved vision for detecting enemy planes at night.
Chocolate
causes acne. No it doesn’t. Stress is one cause of
acne. Chocolate produces Serontin in the brain which has a calming effect of
those who are stressed. Another cause of acne is oil, so it would be better to
cut down on fried food and eat more chocolate.
Carbohydrates
make you fat. Generally the potato gets the blame
here. However, it is not the potato but how we eat it that is the cause of the
problem. Putting huge dollops of butter on baked potatoes or eating greasy fried
chips will make you fat.
Skimmed
milk is useless. No it isn’t. It is true that skimmed
milk is low in vitamin A, but it is rich in minerals, sugar, protein and
vitamin C. Since it is low in fat and cholesterol it is an ideal substitute for
full cream milk.
Bananas
are fattening.
Compared to an apple or an orange that is true. Apples and oranges
contain about 50 calories and a banana contains about 60 calories. Not a huge
difference in the scheme of things.
Cholesterol
kills. Cholesterol is a fat and appears in our bodies in
two forms, HDL(Good cholesterol) and LDL(Bad cholesterol). The fact is that
both these good and bad lipoproteins contain exactly the same cholesterol. HDL dissolves
cholesterol in the liver and LDL delivers it to various organs that need it to
function properly, including our brains which use quite a lot of cholesterol.
Studies show that a high fat diet does produce more cholesterol in the
blood, so people have inferred that
high fat = high cholesterol = heart disease.
However, the latest medical research, such as that referred to in the Catalyst programme, shows that high
fat actually increases the ratio of good cholesterol to bad cholesterol. These findings
mean that high fat diets should reduce the risk of heart disease. Understandably, many doctors are reluctant to come out
publicly and say this.
Margarine
is better than butter.
They both have the same amount of calories but butter has slightly more
saturated fats. This is a healthy natural fat that helps increase the
absorption rate of many nutrients. Margarine is artificially concocted from chemicals
and is very high in trans fats which some doctors say triples the rate of heart
disease. Margarine also lowers the quality of breast milk and decreases immune
and insulin responses. One of the doctors on the Catalyst programme said people
choosing margarine over butter are being influenced by a marketing strategy not a medical
plan. It is also worth pondering that margarine is only one molecule away from
being plastic.
Dr Aseem Malhotra, a respected UK doctor, recently wrote
in the British Medical Journal that fatty foods like butter, milk and eggs have
been demonised. He says his research indicates that the best way to lose weight
is to eat a high fat and low carbohydrate diet.
This seems a little like the famous Atkins Diet of
the 1970s. Dr Atkins said carbohydrates were the cause of obesity and people
should eat steak and salad and avoid carbohydrates at all costs. It was a
popular diet and it seemed to work. People lost weight and they could eat as
much as they liked as long as it wasn’t a carbohydrate. Dr Atkins promoted his
diet with great enthusiasm. Then one day in 2002 he slipped on ice while walking
to work. He hit his head and died some days later of heart complications. He
was 72 years old. Card carrying Vegans immediately said Dr Atkins was killed by
his diet and many people believed them and the Atkins Low Carb/No Carb diet waned
in popularity.
In recent years the Atkins Diet has made a comeback of sorts, as
colleagues of Dr Atkinson have continued to point out that he was a healthy man
who died because of complications resulting from his injuries and a viral
condition which attacked his heart.
So where exactly are we on what constitutes a healthy
diet?
According to the ABC’s Catalyst programme the much
maligned eggs, butter, whole cream milk and fat in general are all now acceptable
food sources. The programme interviewed several cardiologist and medical researchers
who all said that there was no correlation between high fat diets and heart disease.
The programme interviewed cardiologists who said that randomised and controlled clinical trials recently discovered that reduced total
fat or saturated fat diets over several years resulted in NO lowering of heart
disease, stroke or cardiovascular disease. In
other words high fat diets, such as the French enjoy, probably have no
detrimental impact on your health.
What is more,
some of these scientists point out that since the 1970s government and
health department campaigns have reduced fat consumption by 10%. At the same
time obesity rates have lifted by 10%. Could it be that strict low fat diets stop people
from being satiated at the dinner table and consequently they over eat low fat
but high calorie food.
And what of the government health departments who
are now big sponsors of sport and who are telling sporting organisations that
they will get no government sponsorship money while they also obtain sponsorship
dollars from food outlets like KFC and
Hungry Jacks. According to many medical experts KFC and Hungry Jacks provide
food that cannot be related to heart health.
Twenty years ago I had a mild heart attack. While I
was in hospital they also discovered that I had Type Two diabetes. The wise
doctor who informed me of my diabetes said that when I had recovered I would
need to change my lifestyle and do more exercise. He suggested walking as a
suitable activity. He made the valid point that if "energy in" is greater than
"energy out" then you will get fat. You need to burn up that excess energy with a
more active lifestyle. As far as my diet was concerned he said I should generally
follow a low fat, high fibre diet but he was not going to tell me that I could
never eat certain foods ever again.
“Eat what you like, but always in moderation and try
to eat a well balanced diet including all important food groups.”
It seemed like very good advice and I’ve followed it
ever since. It is good to know that, after all these years, that my teeth are not killing me.
