Almost good enough to eat - Food taboos in Brazil

27.10.2004


Some of the first written evidence of food taboos can be found in Leviticus in the Bible, forbidding the consumption of fish and underwater creatures without fins or scales, among other dietary restrictions. Throughout the world in different cultures and religions, a variety of dietary restrictions exist. The origin of these rules is often debated. For Alpina Begossi, Natalia Hanazaki and Rossano Ramos (Universidade de Campinas, Brazil), the question of food taboos led to an investigation of the dietary restrictions among fishers in the Amazon and Atlantic Forest.



The researchers interviewed fishers in 18 coastal communities and along four Amazonian rivers. Begossi and colleagues interviewed adults as well as observed them on fishing trips, noted their diet, and the medicinal uses of fish.

The group discovered certain fish species, especially ones that predated other fish, were the most often mentioned as taboo, along with scaleless fish and Black prochilodus, a species that feeds at the bottom of rivers. Other species the communities avoided included catfish and piranha. The marine fishers on the Atlantic forest generally avoided tuna, rays, and sea catfish.


The researchers especially noticed that food taboos were different, depending on people’s health status. Predatory fish are often tabooed for the ill, while fish that eat plant matter, invertebrates, or are omnivorous are recommended for consumption for ill people. These taboos held true for both the Amazonian fishers as well as the Atlantic Forest fishers.

According to Begossi, "Fish food taboos may have indigenous roots, or they may have been diffused through Portuguese colonists’ contacts."

Food chain characteristics may help explain human food taboos, say the researchers. Most of the species avoided for the ill include species high on the food chain. These fish are more likely to accumulate toxins. The prohibitions on these species may be biologically adaptive for the people, suggest Begossi and colleagues.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
