The 32 year-old theory stating full-fat milk and butter lead to obesity has no grounds, claim experts. The advice aimed at reducing death rate from heart and cordial diseases because of excess fat consuming lacked any solid ground to be relied upon.
In the frames of the theory an official dietary committee of Great Britain advised people to cut their daily fat intake to approx. 30 per cent of energy and saturated fat intake to 10%. At the same time the committee recommended to increase daily carbohydrate intake.
To meet the demand of the nutritionists guidelines, food makers started producing low-fat products, while consumers avoided full-fat milk, cheese, butter and cheese.
Now some experts claim that the advice is partly responsible for weight excess problem because it boosted carbohydrates daily intake.
Scientists say that trials did not back up the advice of nutritionists. A review released recently says that it is quite incomprehensible that such recommendations were proposed to nearly 290 million people living in the America and Great Britain. The scientists concluded that these recommendations should not have been introduced at all.
On the other hand, lots of nutrition scientists and dietary committees severely criticized the outcomes of the review arguing that heart deaths have fallen significantly at the time due to the introduced dietary recommendations.
The experts reviewed data trials that were considered as the ‘golden standard’ of medicine. There were another six trials involving 2,467 men who suffered from a heart attack. The trials tried to find a connection between cholesterol level, dietary fat and heart disease. According to the official results of the review, there is no difference in health condition of examined men and their high / lower fat diet. A researcher of the Robert Gordon University, Aberdeen, Professor Iain Broom says they are picking up evidence against low-fat diets introduction. From his point of view the US and UK governments have virtually destroyed the dairy products industry suggesting that butter, cheese, cream and full fat milk led to heart risk increase, while the opposite is true.
Professor Iain Broom claimed the recommendation to intake more carbohydrates up to 50% was the cause for overweight and obesity and even type 2 diabetes. He believes it’s high time for the UK authorities to make an effort and stop an unrestrained experiment that has gone global and that might have had bad consequences in terms of obesity or overweight explosion.
In 1983 Britons were told to cut its overall fat intake to 30 per cent. However, dietary guidelines were altered in 1991 raising this figure to 35 per cent, while saturated fat stayed at 20 per cent.
This recommendation has remained valid even though new researches have continued to suggest that there is no link between heart disease and consumed fats. Now in GB saturated fat consumption is around 12 per cent.
In 2014 US researchers started a campaign explaining people they have been led down the ‘wrong dietary pathway for decades in abstaining saturated fat while not being advised about the risk of consuming too much carbohydrates and sugar.
It is not the only case scientists have accused faulty interpretations of researches for ‘inventing a myth’ around the part saturated fat plays in heart and cardiovascular diseases. There have been conducted 72 studies that involved up to 600,000 people from 18 countries. A key finding of this statistically powerful researches proved that saturated fat showed no connection with heart diseases.
However, according to statistic data cardiovascular and heart disease mortality under age of 75 dropped by 55 per cent between 1997 and 2007.
According the WHO data, worldwide obesity has more than doubled since 1980.
