Many dietary recommendations support the consumption of dairy products as part of a well-balanced diet but new research says that eating yogurt has no effect on our health.
Scientists have long stated the benefits of eating yogurt on a regular basis, but the effectiveness of this claim has never been proven. Up until now, few studies have specifically examined the relationship between regular yogurt intake and health-related quality of life (HRQL), writes Nature World News.
A team of Spanish scientists set out to establish whether there was a link between eating yogurt on a daily basis and the physical and mental improvement in HRQL in the adult population.
Over the course of the study, which lasted 3.5 years, the team tracked more than 4,000 participants. However, the researchers found that yogurt was not linked to HRQL.
The study results also showed no definite link for individuals who had not been diagnosed with any illnesses, who had never smoked and who followed a Mediterranean diet. Researchers pointed this out as they originally thought that people who did not possess any risk factors could compromise the results of their study.
“In comparison with people that did not eat yogurt, those who ate this dairy product regularly did not display any significant improvement in their score on the physical component of quality of life, and although there was a slight improvement mentally, this was not statistically significant,” lead author Esther López-García said in a statement.
There are a number of reasons why people believe yogurt is beneficial to health. No studies have yet proven its effectiveness, but many have suggested that the consumption of yoghurt could directly or indirectly influence HRQL.
Yogurt is rich in calcium, which protects the bones and could help to combat osteomuscular illnesses. Yogurt has been associated with lower weight increase, lower blood pressure and a lower rate of cardiovascular diseases.
The new study seems to contradict previous research that has linked regular yogurt consumption to a number of health benefits. However, this does not mean that yoghurt is bad for you, or that you should not consume it.
“For future research more specific instruments must be used which may increase the probability of finding a potential benefit of this food,” López-García noted.
