Study: Higher conversion rate of omega-3 through supplements, not conventional food
MIAMI — Omega-3 sourced from dietary supplements may be more beneficial to a healthy diet than omega-3 sourced from conventional food, according to a new meta-analysis published in July by the Public Library of Science Genetics.
Across five population-based categories, representing more than 8,800 subjects, the PLoS has found a lower conversion rate from plant omega-3 (abbreviated ALA) to its final derivatives of EPA and DHA. EPA and DHA of omega-3 can be attained directly from dietary omega-3 supplements or through metabolic conversion from ALA, which is mostly found in seeds and plants.
The study found that the higher ratio of ALA in the body corresponded to lower levels of EPA and DHA, suggesting an inefficiency in conversion of ALA to EPA/DHA.

Preservatives are nothing to sneeze at
A wet spring has made for ideal allergen-creating conditions — the growth of ragweed and an increase in mold. According to a Quest Diagnostics study, sensitization to common ragweed has grown 15% nationally since 2000, while mold grew 12%.
Awareness around preservatives found in nasal allergy sprays also is on the rise, suggested Similasan product manager Jessica Bellows. Similasan recently launched its Nasal Allergy Relief preservative-free nasal mist. Many popular preservatives used in allergy sprays, such as benzalkonium chloride and phenylcarbinol, can exacerbate allergy symptoms.

‘Biggest Loser’ battle royale
NEW YORK — “Biggest Loser” trainer Bob Harper is featured on a diet aid launched earlier this year by Iovate Health Sciences that will go head-to-head against former “Biggest Loser” trainer Jillian Michaels. The Jillian Michaels brand generated $11.9 million for the 52 weeks ended July 10, according to SymphonyIRI Group data across food, drug and mass (excluding Walmart). ”Biggest Loser” and Harper are getting set for that show’s 13th season on NBC this fall, while Michaels will be joining the cast of healthcare professionals on the syndicated health-advice program “The Doctors.”
