Saturated fat heart disease 'myth'

 

Dr Assem Malhotra explains why some saturated fats may not be so bad after all

The risk from saturated fat in foods such as butter, cakes and fatty meat is being overstated and demonised, according to a cardiologist.

Dr Aseem Malhotra said there was too much focus on the fat with other factors such as sugar often overlooked.

It is time to "bust the myth of the role of saturated fat in heart disease", he writes in an opinion piece in the British Medical Journal.

But the British Heart Foundation said there was conflicting evidence.

It added reducing cholesterol through drugs or other means does lower heart risk.

Studies on the link between diet and disease have led to dietary advice and guidelines on how much saturated fat, particularly cholesterol, it is healthy to eat.

Millions of people in the UK have been prescribed statins to reduce cholesterol levels.

Dr Malhotra, a cardiology registrar at Croydon University Hospital, London, says the "mantra that saturated fat must be removed to reduce the risk of cardiovascular disease has dominated dietary advice and guidelines for almost four decades".

Saturated fat

  • Saturated fat is the kind of fat found in butter and lard, pies, cakes and biscuits, fatty cuts of meat, sausages and bacon, and cheese and cream
  • Eating a diet that is high in saturated fat can raise the level of cholesterol in the blood, which increases the risk of heart disease, according to NHS Choices.
  • Most of us eat too much saturated fat - about 20% more than the recommended maximum amount.
  • The average man should eat no more than 30g of saturated fat a day.
  • The average woman should eat no more than 20g of saturated fat a day.

He says saturated fat has been "demonised" and any link with heart disease is not fully supported by scientific evidence.

The food industry has compensated for lowering saturated fat levels in food by replacing it with sugar, he says, which also contributes to heart disease.

Adopting a Mediterranean diet - olive oil, nuts, oily fish, plenty of fruit and vegetables and a moderate amount of red wine - after a heart attack is almost three times as powerful in reducing mortality as taking a statin, writes Dr Malhotra.

However, Prof Peter Weissberg, medical director at the British Heart Foundation, says studies on the link between diet and disease frequently produce conflicting results.

Unlike drug trials, it is difficult to carry out a controlled, randomised study, he says.

"However, people with highest cholesterol levels are at highest risk of a heart attack and it's also clear that lowering cholesterol, by whatever means, lowers risk."

Cholesterol levels can be influenced by many factors including diet, exercise and drugs, in particular statins, he adds.

"There is clear evidence that patients who have had a heart attack, or who are at high risk of having one, can benefit from taking a statin.

"But this needs to be combined with other essential measures, such as eating a balanced diet, not smoking and taking regular exercise."

Statins are a group of medicines that can help lower rates of cholesterol in the blood.

Cholesterol can also be reduced by eating a healthy, balanced diet, maintaining a healthy weight and doing regular physical activity.

    Another day another "expert" opinion. We are all going to die from something, probably information overload. Will anything change from the sheer volume of subject matter being chucked at us? Probably not, because why should anyone pay attention when the advice will likely change in a few weeks. Some time in 2015 my alcohol consumption level will be declared ideal and I will be happy for a day...

    I am over 60 and have drunk full fat milk and eaten butter all my life.
    I weigh 10 stone and my oil pressure is normal.
    My wife rarely uses processed foods in her cooking and I feel that is where the biggest threat lies.
    There is far too much salt, sugar, strange E numbers in processed food. And, drink for that matter!
    People who drink carbonated drinks ight as well eat bags of sugar!

    As long as you lead a balanced lifestyle, eat balanced amounts of different types of food and do a couple of hours of exercise per week, you will see results on your figure, your health and your stress levels. No scientist needs to tell me that, I can work it out for myself.

    I work on the rule that a little of what you fancy does you good, over indulgence of anything is bad for you, problem is there's so much bad science out there its hard to find the truth amongst it all these days.

    Tne average mortal doesn't know what to believe when confronted with all these contradictions. Furthermore each body is different and reacts differently. Sorry, no we are not all equal. It mentally tires me to listen to all this. I would say eat small quantities of everything without excesses. The rest is up to God : You go when you go !
