Having three servings of dairy products a day could help reduce the risk of heart disease, according to a new study.
Recent years have seen the rise of anti-pharmaceutical health fashion, with advocates who say that whole milk and other dairy products, rich in saturated fats, raise LDL cholesterol, which increases the risk of cardiovascular disease.
But researchers said they found that those who consumed three servings of milk, cheese, butter or cream per day were almost twice as likely to suffer heart disease and stroke, compared to having fewer servings.
The team, led by McMaster University in Ontario, Canada, says its findings show that dairy consumption should not be discouraged, and should in fact be encouraged in low and middle income countries where dairy intake is low.

Currently, the US Dietary Guidelines. UU For Americans 2015-2020 they recommend no more than three servings of dairy products a day and advises choosing fat-free and low-fat options.
This is based on research that has shown that the saturated fats found in the products of integrated fats increase your LDL cholesterol, a marker of heart disease.
However, past evidence has suggested that there are a number of nutrients found in dairy products, including calcium, potassium, magnesium, vitamins K1 and K2, and probiotics (in yogurt) that could contribute to a healthy diet.
"Diet is one of the most important modifiable risk factors for chronic disease," lead author Dr. Mahshid Dehghan, a research associate at McMaster University, told the Daily Mail Online.
"And since dairy products contain magnesium, potassium and all these vitamins, we wanted to see if there was a link between consumption and chronic disease."
For the study, the team looked at more than 136,000 people from 21 countries who had participated in the Prospective Urban Urban Epidemiology (PURE) study.
The PURE study analyzes the environmental, social and biological effects on obesity and chronic health problems, including heart disease, diabetes and cancer.
The participants, who were between 35 and 70 years old, were divided into four categories: no dairy products, less than one serving per day, one to two servings per day and more than two servings per day.
It was determined that a serving equals a glass of milk, a cup of yogurt, a slice of 15 grams of cheese or a teaspoon of butter.
The researchers looked at the dietary intakes of the participants at the start of the study in 2003 and followed them for approximately nine years.
It was found that the high-intake group, which had an average of three servings per day, had lower death rates due to cardiovascular and non-cardiovascular causes, heart disease and stroke compared to the no-intake group.
In addition, those who only consumed whole-fat fats with a higher intake -about three servings per day- had lower rates of death and heart disease than those who consumed less than 0.5 servings of whole milk per day.
The team also found that the highest dairy consumption was recorded in North America and Europe, where participants had four or more servings per day.
Consumption was lowest in South Asia and Africa, where participants ate an average of less than one serving per day.
"There are many factors that affect the pattern of consumption, because the food culture in several countries is different," said Dr. Dehghan.
"But we see the same tendencies." It does not matter, in which country we look, the trends were the same. "
She says more research is needed on why dairy products are linked to low levels of heart disease, as well as to investigate quality of the diet in general in different countries.
"What I really want to emphasize is that consumption should not be discouraged, but encouraged, especially in low-income countries and even in high-income countries where consumption is low," said Dr. Meghan.
"We are not saying that people who consume seven servings of dairy a day increase their consumption, but that the three servings, moderation, are good for you."
