Fast food has been linked to depression in a new study. Check out the March 30, 2012 news release from FECYT – Spanish Foundation for Science and Technology, published in the journal Public Health Nutrition. Could fast-food also be linked to road rage as well as depression – to anger turned inwards as well as angry outbursts at perception of disrespect?
Also check out the study or its abstract, “Fast-food and commercial baked goods consumption and the risk of depression.” And see this other study’s abstract, “Dietary fat intake and the risk of depression: the SUN Project.”
According to a recent study headed by scientists from the University of Las Palmas de Gran Canaria and the University of Granada, eating commercial baked goods (fairy cakes, croissants, doughnuts, or similar snacks) and fast food (hamburgers, hotdogs, and pizza) is linked to depression.
Published in the Public Health Nutrition journal, the results reveal that consumers of fast food, compared to those who eat little or none, are 51% more likely to develop depression.
Furthermore, a dose-response relationship was observed. In other words this means that “the more fast food you consume, the greater the risk of depression,” explains Almudena Sánchez-Villegas, lead author of the study, to SINC, according to the news release.
The study demonstrates that those participants who eat the most fast food and commercial baked goods are more likely to be single, less active and have poor dietary habits, which include eating less fruit, nuts, fish, vegetables and olive oil. Smoking and working more than 45 hours per week are other prevalent characteristics of this group.
A long-term study
With regard to the consumption of commercial baked goods, the results are equally conclusive. “Even eating small quantities is linked to a significantly higher chance of developing depression,” as the university researcher from the Canary Islands points out in the news release.
The study sample belonged to the SUN Project (University of Navarra Diet and Lifestyle Tracking Program). See, Researchers from the SUN Project.
It consisted of 8,964 participants that had never been diagnosed with depression or taken antidepressants. They were assessed for an average of six months, and 493 were diagnosed with depression or started to take antidepressants.
This new data supports the results of the SUN project in 2011, which were published in the PLoS One journal. The project recorded 657 new cases of depression out of the 12,059 people analyzed over more than six months. A 42% increase in the risk associated with fast food was found, which is lower than that found in the current study.
Sánchez-Villegas concludes that “although more studies are necessary, the intake of this type of food should be controlled because of its implications on both health (obesity, cardiovascular diseases) and mental well-being.”
The impact of diet on mental health
Depression affects 121 million people worldwide. This figure makes it one of the main global causes of disability-adjusted life year. Further still, in countries with low and medium income it is the leading cause.
However, little is known about the role that diet plays in developing depressive disorders. Previous studies suggest that certain nutrients have a preventative role. These include group B vitamins, omega-3 fatty acids and olive oil. Furthermore, a healthy diet such as that enjoyed in the Mediterranean has been linked to a lower risk of developing depression.

Probiotics and H. Pylori
Probiotics and h. Pylori is part of studies of preventative and even personalized medicine. See the UC Davis article, UC Davis: Prized Writing : Probiotics: the future of preventative Medicine.
Consumers with ulcers have been looking for help for decades to end the H. pylori bacteria that causes uclers. Sacramento supermarkets sell a wide variety of probiotic cultured milks from goat’s or cow’s milk, from coconut ‘milk’ and from soy. You can buy probiotics in health food store ‘coolers,’ but have they really helped heal ulcers?
The Slavic community in various cities of the USA and other nations sometimes turns to Siberian pine nut oil, an ancient remedy sometimes used in Russia, Siberia, and China as folkloric medicine to help ulcers heal by attacking the pylori. See the article, Extra virgin pine nut oil improves metabolism and aids digestion.
Check out, Heal peptic ulcers naturally. But what is the newest approach to treat ulcers? It’s a new probiotic. Check out the February 24, 2011 article, “Probiotic identified to treat ulcers.” It’s about using a certain type of bacteria, a probiotic culture, to fight another type of bacteria.
According to a February 24, 2011 news release bsed on a study from the American Society for Microbiology , “Probiotic identified to treat ulcers,” researchers from Spain have identified a strain of probiotic bacteria that may be useful in treating ulcers caused by Helicobacter pylori. They report their findings in the February 2011 issue of the journal Applied and Environmental Microbiology.
“H. pylori is considered one of the major risk factors underlying the development of gastritis and gastric and duodenal ulcers,” write the researchers, according to the study. “Currently, antibiotic-based treatment for H. pylori infection is neither sufficient nor satisfactory, with the most successful treatments reaching 75 to 90% eradication rates. The use of probiotics is a potentially promising tool to prevent H. pylori.”
According to an expert consultation conducted by the Food and Agriculture Organization and the World Health Organization probiotics are “live microorganisms which when administered in adequate amounts confer a health benefit to the host.” The regular intake of probiotic microoganisms has been demonstrated to prevent several disorders including diarrhea and inflammatory bowel disease, according to the news release.
Among probiotics Bifidobacterium is one of the favorite genera in studies focused on the prevention of gastrointestinal infection and is often used in fermented dairy products or food supplements. Some studies have been done in vitro (in test tubes or petri dishes) showing bifidobacterial activity against H. pylori.
In this study, the researchers tested numerous strains of bifidobacteria isolated from the feces of breast-fed infants for activity against H. pylori. They identified one strain (Bifidobacterium bifidum CECT 7366) that under certain conditions had an inhibition level of nearly 95% in vitro and tested its activity against infection in mice.
After 21 days, mice treated with the potentially probiotic strain developed significantly less ulcers than the control group. Additional tests suggest that treatment partially relieved damage to gastric tissue caused by H. pylori infection. Ingestion of the bacteria did not induce any disease or mortality in both healthy and immunocompromised mice.
“The results presented here confer to strain B. bifidum CECT 7366 the status of a probiotic bacterium with functional activity against H. pylori,” write the researchers, in the news release. “Human clinical trials must be performed before commercialization of this strain can be approved.” Check out the study, “Novel Probiotic Bifidobacterium bifidum CECT 7366 Strain Active against the Pathogenic Bacterium Helicobacter pylori.”
