Q: MADRID, April 21 (UPI) -- It's got calcium, protein and probiotics. What's not to love? Yogurt has been prominently featured in a variety of nutritional guidelines and dietary recommendations, as well as prescribed as a natural antidote to a number of health problems. 
  
 But a new study out of Spain found no link between regular yogurt consumption and improved health outcomes. Those who ate yogurt on regular basis were not any more or less likely to experience disease, disability or disorder. 
  
 The study, led by researchers from the Autonomous University of Madrid, looked at results from a short survey about dietary habits and factors related to a person's health-related quality of life (HRQL). In analyzing the responses of 4,445 Spanish adults over 3 1/2 years, researchers found no correlation between yogurt consumption and improved physical health. 
  
 "The regular consumption of yogurt was not linked to health-related quality of life," lead author Esther Lopez-Garcia said in a press release. "For future research more specific instruments must be used which may increase the probability of finding a potential benefit of this food." 
  
 The new research was published in the Journal of the Academy of Nutrition and Dietetics. 
  
 Researchers also found no link between yogurt and improved health for those who don't smoke and eat a Mediterranean diet -- thus eliminating the chance that poor health choices might disguise yogurt's benefits among the general population. 
  
 "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," Lopez-Garcia added. 
  
 Yogurt has been heralded by a number of nutritionists, and while dairy is usually trumpeted as an ideal source of calcium -- essential for bone health -- most of the latest praise is based on the idea that yogurt provides beneficial micro-organisms (or probiotics). 
  
 A number of a previous studies have confirmed the importance of bacteria in the human gut in dictating positive health, both mental and physical. But the science remains murky on exactly which micro-organisms are helpful -- and whether or not foods like yogurt can deliver those good micro-organisms. ||||| Yogurt for health? Not so fast, study warns 
  
 The yogurt industry is a multibillion dollar behemoth, driven mostly by the belief that eating partially spoiled dairy products is good for your health. Now, a new study by researchers from the Autonomous University of Madrid finds that the go-to breakfast for millions of people may have no discernible health benefits at all. 
  
 The study followed 4,445 Spanish adults, chronicling their quality of life as it relates to health, along with their yogurt intake for an average period of 3.5 years. They found that yogurt consumption appeared to have no impact on quality of life. More specifically, those who ate six or fewer servings per week were no worse off than those who ate at least one serving every day. Better indicators of health included illness diagnoses, whether or not a person ever smoked and whether or not they followed the Mediterranean Diet. 
  
 There was a catch, however: Yogurt consumption was only measured at the start of the study for each participant, between 2008 and 2010 (the study continued through 2012). It's possible, then, that yogurt consumption may have changed from person to person, especially given its meteoric rise in popularity in the late aughts. Still, based on the results it's unlikely that eating yogurt (or not eating yogurt) had much of an impact when looking at health from an overall standpoint. 
  
 That's not to say that yogurt doesn't have more discreet benefits, which is why the researchers would like to study it more directly. 
  
 "For future research more specific instruments must be used which may increase the probability of finding a potential benefit of this food," said lead author Esther López-García. "This is because the majority of studies have focused on the effect as a whole, but it would be interesting to evaluate the independent association between each type of product and global health indicators." 
  
 The biggest fallout from the study will likely have to do with the way yogurt manufacturers label and advertise their products. Producers often use the health angle to market yogurt, even when it's not always true (Dannon recently agreed to soften its claims for its Activia brand, which touted the digestive benefits of its probiotic content). Now, as research finds that even claims of overall health may be spurious, advertisers may have to change their tune until more detailed research is conducted. 
  
  
  
  ||||| Yogurt is frequently lauded for its healthful properties, but a new study investigating the effects of regular yogurt consumption has suggested that it does not lead to improvements in health. 
  
  
  
 Regular yogurt consumption has been associated with reduced risk of hypertension, cardiovascular disease and type 2 diabetes. Regular yogurt consumption has been associated with reduced risk of hypertension, cardiovascular disease and type 2 diabetes. 
  
 The study, published in the Journal of the Academy of Nutrition and Dietetics, followed 4,445 Spanish adults, analyzing the relationship between the participants' health-related quality of life and yogurt consumption for an average of 3.5 years. 
  
 "The regular consumption of yogurt was not linked to health-related quality of life," states lead author Esther López-García, of the Autonomous University of Madrid. "For future research more specific instruments must be used which may increase the probability of finding a potential benefit of this food." 
  
 Health-related quality of life is a concept that encompasses "aspects of overall quality of life that can be clearly shown to affect health - either physical or mental," as defined by the the Centers for Disease Control and Prevention (CDC). For individuals, this can involve health conditions and risks as well as socioeconomic support and status. 
  
 In Spain, where the study was conducted, the main dietary guidelines support the consumption of dairy products such as yogurt as part of a healthy, balanced diet, just as they do in many other countries. 
  
 "This is because the majority of studies have focused on the effect as a whole, but it would be interesting to evaluate the independent association between each type of product and global health indicators," suggests López-García. 
  
 Several experts have previously suggested that yogurt could influence health-related quality of life due to its high calcium content - vital for protecting the bones against debilitating disease. Other research has associated yogurt consumption with direct health benefits, such as a lower risk of type 2 diabetes. 
  
 No significant improvements in health-related quality of life for regular yogurt eaters 
  
 For the study, the researchers recruited 4,445 participants between 2008-2010 aged 18 and over. The routine yogurt consumption of the participants was recorded at the start of the study along with a validated diet history. 
  
 The health-related quality of life for the participants was then measured using surveys up until 2012, giving an average follow-up period of 3.5 years. 
  
 "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," states López-García. 
  
 Specifically, participants that consumed six or fewer servings of yogurt a week reported similar physical health survey scores compared with participants that consumed at least one serving every day. These results were similar among participants that had no diagnosed illnesses, never smoked or followed the Mediterranean diet. 
  
 Unfortunately, the researchers only assessed yogurt consumption at the start of the study. Individual levels of yogurt consumption may have changed during the follow-up period. Additionally, the researchers did not track the consumption of other food items that may have influenced their findings. 
  
 The findings of the study could be used to help evaluate any claims from the dairy industry concerning the healthful properties of yogurt. The US Department of Agriculture, for example, must review any such claims put forward by the food industry in order to allow or reject their commercial use. 
  
 Last month, Medical News Today reported on a study that set out to investigate whether there was any truth behind the proverbial claim that "an apple a day keeps the doctor away." Although regular apple consumption did not reduce the use of health care services, it did reduce reliance on prescription medications. ||||| Does yogurt deserve a spot in the fridge?

 Yogurt has long worn a health halo, but a new study in the Journal of the Academy of Nutrition and Dietetics suggests the food may not hold as many benefits as previously thought. 
  
 In the study, researchers from the Autonomous University of Madrid analyzed data on 4,445 adults and their yogurt consumption that was collected over nearly four years. They found that those who ate yogurt regularly did not have any significant improvement in their health-related quality of life — physically or mentally. (There was a slight improvement in mental health, but it wasn’t statistically significant.) 
  
 The new study seemingly contradicts previous research that has linked regular yogurt consumption to a slew of health benefits. 
  
 Research published last year in the journal BMC Medicine, for instance, found that people who eat yogurt every day have a lower risk of developing Type 2 diabetes. A recent study from the American Heart Association also showed that adding more yogurt to your diet without increasing the number of calories you eat may help lower risk of developing high blood pressure. And a study published last year in the American Journal of Clinical Nutrition found that people who regularly eat yogurt may gain less weight over time. 
  
 Eating yogurt has even been shown to help pregnant women and their fetuses. A study published in the journal of the American Society for Microbiology found that yogurt containing the probiotic Lactobacillus rhamnosus successfully protected children and pregnant women against exposure to toxic metals like mercury and arsenic. 
  
 So … what are we supposed to think? 
  
 New York-based nutritionist Karen Ansel, RD, tells Yahoo Health that people shouldn’t toss their yogurt containers just yet. “Plain, unsweetened yogurt is one of the healthiest foods a person can eat,” she says. “It’s packed with calcium and potassium, two nutrients that most of us don’t get enough of.” |||||

Those who eat lots of yogurt because they think it's a health food might have to reassess things: A study out of Spain suggests that yogurt provides virtually no health benefits, reports Medical News Today. Researchers followed more than 4,000 people for an average of three and a half years, and found no correlation between eating the stuff and better overall health. "The regular consumption of yogurt was not linked to health-related quality of life," says lead author Esther Lopez-Garcia of the Autonomous University of Madrid. But there's hope: "For future research, more specific instruments must be used which may increase the probability of finding a potential benefit of this food." As UPI notes, the food has long gotten praise as a source of calcium and, more recently, for its beneficial micro-organisms, or probiotics, thought to improve the digestive system. Yahoo, meanwhile, talks to a nutritionist who maintains that “plain, unsweetened yogurt is one of the healthiest foods a person can eat,” because it's "packed with calcium and potassium, two nutrients that most of us don’t get enough of.” Still, the findings published in the Journal of the Academy of Nutrition and Dietetics could force the industry to tamp down health claims, notes Nature World Report. "Advertisers may have to change their tune until more detailed research is conducted." (In other food news, Diet Pepsi is ditching aspartame.)
