Consuming Polyunsaturated Fatty Acids May Lower the Incidence of Gum Disease

26 Oct 2010 --- The study involved over 9,000 adults who participated in NHANES between 1999 and 2004 who had received dental examinations. Dietary DHA, EPA and LNA intake were estimated from 24-hour food recall interviews and data regarding supplementary use of PUFAs were captured as well.

Oct 26 2010 --- Periodontitis, a common inflammatory disease in which gum tissue separates from teeth, leads to accumulation of bacteria and potential bone and tooth loss. Although traditional treatments concentrate on the bacterial infection, more recent strategies target the inflammatory response. In an article in the November issue of the Journal of the American Dietetic Association, researchers from Harvard Medical School and Harvard School of Public Health found that dietary intake of polyunsaturated fatty acids (PUFAs) like fish oil, known to have anti-inflammatory properties, shows promise for the effective treatment and prevention of periodontitis.

"We found that n-3 fatty acid intake, particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are inversely associated with periodontitis in the US population," commented Asghar Z. Naqvi, MPH, MNS, Department of Medicine, Beth Israel Deaconess Medical Center. "To date, the treatment of periodontitis has primarily involved mechanical cleaning and local antibiotic application. Thus, a dietary therapy, if effective, might be a less expensive and safer method for the prevention and treatment of periodontitis. Given the evidence indicating a role for n-3 fatty acids in other chronic inflammatory conditions, it is possible that treating periodontitis with n-3 fatty acids could have the added benefit of preventing other chronic diseases associated with inflammation, including stoke as well."

Using data from the National Health and Nutrition Examination Survey (NHANES), a nationally representative survey with a complex multistage, stratified probability sample, investigators found that dietary intake of the PUFAs DHA and (EPA) were associated with a decreased prevalence of periodontitis, although linolenic acid (LNA) did not show this association.

The study involved over 9,000 adults who participated in NHANES between 1999 and 2004 who had received dental examinations. Dietary DHA, EPA and LNA intake were estimated from 24-hour food recall interviews and data regarding supplementary use of PUFAs were captured as well. The NHANES study also collected extensive demographic, ethnic, educational and socioeconomic data, allowing the researchers to take other factors into consideration that might obscure the results.

The prevalence of periodontitis in the study sample was 8.2%. There was an approximately 20% reduction in periodontitis prevalence in those subjects who consumed the highest amount of dietary DHA. The reduction correlated with EPA was smaller, while the correlation to LNA was not statistically significant.

In an accompanying commentary, Elizabeth Krall Kaye, PhD, Professor, Boston University Henry M. Goldman School of Dental Medicine, notes that three interesting results emerged from this study. One was that significantly reduced odds of periodontal disease were observed at relatively modest intakes of DHA and EPA. Another result of note was the suggestion of a threshold dose; that is, there seemed to be no further reduction in odds or periodontal disease conferred by intakes at the highest levels. Third, the results were no different when dietary plus supplemental intakes were examined. These findings are encouraging in that they suggest it may be possible to attain clinically meaningful benefits for periodontal disease at modest levels of n-3 fatty acid intakes from foods.

Foods that contain significant amounts of polyunsaturated fats include fatty fish like salmon, peanut butter, margarine, and nuts.

Food for Thought: UK Teenagers Losing Learning Time Due to Hunger

27 Jun 2017 --- Teenage pupils in high school can lose around 51 minutes’ worth of vital learning time a day because their concentration levels dip due to hunger. This is according to the results of a survey conducted in the UK by Kellogg’s. The survey results show that 82 percent of teachers in Britain have seen teens arriving at school hungry every day. And nearly four in 10 teachers believed one reason children in their class were hungry was due to their parents being unable to afford food for breakfast.

Heightened Risk in Rice? Toxicity of Thioarsenates for Plants Uncovered

27 Jun 2017 --- Although it is a staple food in many regions of the world, rice sometimes contains levels of arsenic that are hazardous to our health. An interdisciplinary team of researchers at the University of Bayreuth has now discovered that there are arsenic compounds which have a toxic effect on plants and yet had not previously been considered in connection with chemical analyses of rice and the estimated health risks for humans. The research concerns thioarsenates, compounds made up of arsenic and sulphur, which may be present in rice fields more often than previously assumed.
