Low Fat Diets do not Curb Heart Disease

However, a recent data shows that replacing saturated fats and trans fatty acids with omega 6 fatty acids, without a corresponding rise in omega 3 fatty acids, seems to increase the risk of death from coronary heart and cardiovascular diseases

In a setback to those who have switched to low-saturated fat diets for better heart health, a leading US cardiovascular research scientist has claimed diets low in saturated fat or based on Omega 6 fats do not curb heart disease risk or help you live longer.

“Current dietary advice to replace saturated fats with carbohydrates or omega 6-rich polyunsaturated fats is based on flawed and incomplete data from the 1950s,” declared James DiNicolantonio in the medical journal Open Heart.

The best diet to boost and maintain heart health is one low in refined carbohydrates, sugars and processed foods, he recommended.

Anyone who has had a heart attack should not be thinking of replacing saturated fats with refined carbs or omega 6 fatty acids — particularly those found in processed vegetable oils containing large amounts of corn or safflower oil, he added.

“Dietary guidelines should be urgently reviewed and the vilification of saturated fats stopped to save lives,” he insisted.

DiNicolantonio said the idea that fat causes heart disease was based on a flawed 1950s study which used data from six countries but excluded data from another 16.

This study “seemingly led us down the wrong ‘dietary road’ for decades to follow”, he said.

There is now a strong argument in favour of the consumption of refined carbohydrates as the causative dietary factor behind the surge in obesity and diabetes in the US.

While a low fat diet may lower ‘bad’ (LDL) cholesterol, there are two types of LDL cholesterol.

“Switching to carbs may increase pattern B (small dense) LDL which is more harmful to heart health than pattern A (large buoyant) LDL, as well as creating a more unfavourable overall lipid profile,” DiNicolantonio noted.

However, a recent data shows that replacing saturated fats and trans fatty acids with omega 6 fatty acids, without a corresponding rise in omega 3 fatty acids, seems to increase the risk of death from coronary heart and cardiovascular diseases.

“We need a public health campaign as strong as the one we had in the 70s and 80s demonising saturated fats, to say that we got it wrong,” urged DiNicolantonio.

“Eating a Mediterranean-style diet rich in fruit, veg, pulses and fish would help lower cholesterol and reduce the risk of coronary heart disease,” he suggested. (IANS)

Insufficient Sleep In Poor People Linked With Heart Disease

People with lower socieconomic have less sleep and are more prone to heart diseases

Insufficient sleep is one reason why poor people are more prone to heart disease, researchers have warned.

People with lower socioeconomic status sleep less for a variety of reasons: they may do several jobs, work in shifts, live in noisy environments, and have greater levels of emotional and financial stress, according to the study published in the journal Cardiovascular Research.

The study found that short sleep explained 13.4 per cent of the link between occupation and coronary heart disease in men.

“The absence of mediation by short sleep in women could be due to the weaker relationship between occupation and sleep duration compared to men,” said study author Dusan Petrovic, from the University Centre of General Medicine and Public Health, Lausanne in Switzerland.

“Women with low socioeconomic status often combine the physical and psychosocial strain of manual, poorly paid jobs with household responsibilities and stress, which negatively affects sleep and its health-restoring effects compared to men,” he said.

The study was part of the Lifepath project, and pooled data from eight cohorts totalling 111,205 participants from four European countries.

Socioeconomic status was classified as low, middle, or high according to the father’s occupation.

A history of coronary heart disease and stroke was obtained from clinical assessment, medical records and self-report.

Average sleep duration was self-reported and categorised as recommended or normal sleep (six to 8.5), short sleep (six), and long sleep (more than 8.5) hours per night.

The contribution of insufficient sleep was investigated using a statistical approach called mediation analysis.

The study estimates the contribution of sleep to an association between the socioeconomic status and the coronary heart disease or stroke.

“Structural reforms are needed at every level of society to enable people to get more sleep. For example, attempting to reduce noise, which is an important source of sleep disturbances, with double glazed windows, limiting traffic, and not building houses next to airports or highways,” he added.
