Insects are a sustainable source of omega-3

Here's a solution to the fish burps of Omega-3 capsules.

Insect oil is a possible new source of the healthy omega-3 fatty acid. Insects make fatty acids by nature and can live on organic waste. Wageningen University examines which insects can best be used for oil and what their optimal diet should be.
Insects are already used as a source of protein for man and beast. In the protein extraction process also oil is extracted. This insect oil is currently thrown away. That is a shame, proves researcher Daylan Tzompa Sosa of Wageningen University.
Fatty acids
In her PhD-research, Tzompa Sosa looks at milkfats. Out of curiosity, she once did similar fat analysis with oil that was left over after protein extraction of insects by a lab colleague. “The oil appeared to contain a lot of fatty acids, both saturated and unsaturated.” In addition, Tzompa Sosa demonstrated that the oil can be extracted in an environmentally friendly way, giving also the highest return and the best quality oil compared to other processes. Tzompa Sosa extracted oil from for instance meal worms, beetle larvae, crickets, cockroaches, grasshoppers and soldier flies. “All the oils smell differently, some nicer than others”, the Wageningen scientist says.
Fish
The industry is interested in sustainable fatty acids like omega-3 and lauric acid. The main source for omega-3 is currently fish. It is added to the feed of cats and farm raised salmon, to foodstuffs and put in capsules. “Cats die when they get a full vegetable diet without these additives. That is why they normally eat meat. Farm raised salmons get wild caught fish or fishmeal instead.” Also humans need to take in a certain amount of fatty acids. Lauric acid (also to be found in coconut oil for example) is supposed to have bactericidal and virus obliterate qualities. Furthermore, the use of insect oil in for example cosmetics is obvious.
Properties
To research breeding, diet and processing of insects for oil, the Wageningen fat researchers are working together with entomologists and bio based experts of Wageningen UR. One of these researches concerns an analysis of the different fractions in oil and their properties, because these fractions have different liquid and solid phase. Also a risk analysis of use of the oil for man and beast will be done.

Insect diet helped early humans build bigger brains, study suggests

Is your neurologist having you forage for your food to spur your higher-level cognitive functions?  And that low-fat, high-protein diet from this would probably be better than anything you get in the hospital.

Figuring out how to survive on a lean-season diet of hard-to-reach ants, slugs and other bugs may have spurred the development of bigger brains and higher-level cognitive functions in the ancestors of humans and other primates, suggests research from Washington University in St. Louis. “Challenges associated with finding food have long been recognized as important in shaping evolution of the brain and cognition in primates, including humans,” said Amanda D. Melin, PhD, assistant professor of anthropology in Arts & Sciences and lead author of the study.
“Our work suggests that digging for insects when food was scarce may have contributed to hominid cognitive evolution and set the stage for advanced tool use.” Based on a five-year study of capuchin monkeys in Costa Rica, the research provides support for an evolutionary theory that links the development of sensorimotor (SMI) skills, such as increased manual dexterity, tool use, and innovative problem solving, to the creative challenges of foraging for insects and other foods that are buried, embedded or otherwise hard to procure.
Published in the June 2014 Journal of Human Evolution, the study is the first to provide detailed evidence from the field on how seasonal changes in food supplies influence the foraging patterns of wild capuchin monkeys.
The study is co-authored by biologist Hilary C. Young and anthropologists Krisztina N. Mosdossy and Linda M. Fedigan, all from the University of Calgary, Canada.
It notes that many human populations also eat embedded insects on a seasonal basis and suggests that this practice played a key role in human evolution.
“We find that capuchin monkeys eat embedded insects year-round but intensify their feeding seasonally, during the time that their preferred food – ripe fruit – is less abundant,” Melin said. “These results suggest embedded insects are an important fallback food.”
Previous research has shown that fallback foods help shape the evolution of primate body forms, including the development of strong jaws, thick teeth and specialized digestive systems in primates whose fallback diets rely mainly on vegetation.

This study suggests that fallback foods can also play an important role in shaping brain evolution among primates that fall back on insect-based diets, and that this influence is most pronounced among primates that evolve in habitats with wide seasonal variations, such as the wet-dry cycles found in some South American forests. “Capuchin monkeys are excellent models for examining evolution of brain size and intelligence for their small body size, they have impressively large brains,” Melin said. “Accessing hidden and well-protected insects living in tree branches and under bark is a cognitively demanding task, but provides a high-quality reward: fat and protein, which is needed to fuel big brains.”
But when it comes to using tools, not all capuchin monkey strains and lineages are created equal, and Melin’s theories may explain why.
Perhaps the most notable difference between the robust (tufted, genus Sapajus) and gracile (untufted, genus Cebus) capuchin lineages is their variation in tool use. While Cebus monkeys are known for clever food-foraging tricks, such as banging snails or fruits against branches, they can’t hold a stick to their Sapajus cousins when it comes to the
innovative use and modification of sophisticated tools.
One explanation, Melin said, is that Cebus capuchins have historically and consistently occupied tropical rainforests, whereas the Sapajus lineage spread from their origins in the Atlantic rainforest into drier, more temperate and seasonal habitat types.
“Primates who extract foods in the most seasonal environments are expected to experience the strongest selection in the ‘sensorimotor intelligence’ domain, which includes cognition related to object handling,” Melin said. “This may explain the occurrence of
tool use in some capuchin lineages, but not in others.”
Genetic analysis of mitochondial chromosomes suggests that the Sapajus-Cebus diversification occurred millions of years ago in the late Miocene epoch.
