This article is part of the Research TopicAftereffects in face processingView all 14 articles
An important question regarding face aftereffects is whether it is based on face-specific or lower-level mechanisms
One method for addressing this is to explore how adaptation in upright or inverted
photographic positive or negative faces transfers to test stimuli that are either upright or inverted and normal or negated
A series of studies are reported in which this is tested using a typical face identity aftereffect paradigm in unfamiliar and famous faces
Results showed that aftereffects were strongest when the adaptor matched the test stimuli
aftereffects did not transfer from upright adaptors to inverted test images
but did transfer from inverted adaptors to upright test images in famous faces
The results are interpreted in terms of how identity adaptation interacts with low-level adaptation and highlight differences in the representation of famous and unfamiliar faces
Low-level adaptation is tied closely to the physical properties of the stimuli: the adaptor must match the test stimuli
the adaptor and the test do not have to match so well and aftereffects can transfer across viewpoints and images
There is sufficient evidence to suggest that both lower- and higher-level adaptation mechanisms are involved in face aftereffects
but the relative involvement of each is not well understood
In their seminal study, Webster and MacLin (1999) created a series of stimuli of faces that were distorted from the norm in a Gaussian fashion in vector format
The resulting set of faces was presented to participants using a nulling-match procedure
whereby participants had to adjust a distorted face to appear normal
After inspecting an adaptation face for 5 min and for 8 s between each test image
participants had to adjust the distorted face such that it would appear normal
The adjustments the participants made were distorted in the opposite direction to the adaptation stimuli the participants had seen
The results were replicated in a normal rating procedure
These results indicate that these aftereffects involve at least some higher-level mechanisms
Yamashita et al. (2005) found that the magnitude of face aftereffects are dependent on the visual similarities between the adaptor and the test stimuli
changes that affect the recognizability of faces affect the magnitude of aftereffects more than changes that do not affect the recognizability
Size and color differences between the adaptor and the test stimuli reduce the magnitude of adaptation significantly less than spatial frequency and contrast differences between the adaptation and test stimuli
Often considered similar to FDAEs are face identity aftereffects (FIAEs), whereby the perceived identity of a face is altered after adaptation to a particular identity. Leopold et al. (2001) conducted an elaborate study into FIAEs. In their study, 200 faces were morphed together to produce a prototype face. This was assumed to be the center of the face-space (see Valentine, 1991)
each face identity could be measured in terms of Euclidean distances from the prototype face
a series of faces were created ranging from the prototype face to the face identity
each differing in identity “strength.” Identification thresholds (the required identity strength to perceive the face identity) were taken before and after adaptation to an anti-face identity (opposite from the face identity in terms of Euclidean geometry)
the identification threshold was lowered by 12.5% suggesting it was easier to perceive the identity following adaptation since the prototypical face is shifted
The magnitude of the aftereffects were similar for upright and inverted faces
provided that the adaptation and test faces were in the same orientation
Given that the representations of faces depends on levels of familiarity it is important to explore how face aftereffects represent themselves faces that are not unfamiliar
There have been limited studies conducted on adaptation in famous faces specifically
the aftereffects demonstrated by Jiang et al
Familiar faces have been viewed much more extensively in a variety of contexts and illumination conditions
Carbon and Leder(2005, 2006) have shown that both the FDAE and the FIAE are longer lasting in famous faces than unfamiliar faces, but do not transfer to other faces in the same way that aftereffects in unfamiliar faces do (Carbon et al., 2007). Hills et al. (2010) have shown that non-visual adaptors can cause aftereffects in famous faces
exposure to the name or to the voice cause aftereffects in faces to a similar degree as adaptation to a different image of the face
This background summarizes three key areas of face aftereffects that require further elaboration: firstly
whether there is reliance on specific face-processing mechanisms in the FIAE
This can be tested by exploring how the aftereffects transfer from upright to inverted stimuli and vice versa
how much (relatively) of the FIAE is low-level and how much is high-level
Part of this can be explored by assessing how aftereffects transfer across different image manipulations and most importantly to different images
A third question is whether the aftereffects are different across famous and unfamiliar faces
whereas the faces in Experiment 1b were unfamiliar
mean age 21 years) Cardiff University students undertook this experiment as partial fulfillment of a course requirement
All participants had normal or corrected-to-normal vision
All were White British nationals who were familiar with the famous faces
Two different images of George Bush and Tony Blair were collected
They were matched for dimensions (100 mm × 160 mm) and resolution (72 dpi)
Image one of George Bush was matched for pose and lighting with image one of Tony Blair
A series of morphs were created using Smartmorph™ Software with 200 anchor points
Fifty morphs were created that ranged from 100% George Bush to 100% Tony Blair in increments of 2% (thus 50 images)
Image two of George Bush was in a different pose and under different lighting conditions from image one of George Bush and matched to image two of Tony Blair
The “image two” pair were morphed together in the same way as the image one pair
The 100% images for each identity and each pair were also used as the adaptor
These two sets of morphs were inverted into two addition sets. Two negated sets were also created using Adobe Photoshop™ image manipulation software. These negated sets were subsequently inverted to create two additional sets of stimuli. The 50% image of each type of stimulus is presented in Figure 1
All stimuli were presented using SuperlabPro 2™ Research Software on an RM PC
Examples of the stimuli used in this Experiment
The adaptor was manipulated between subjects with four levels (same image
A within-subjects manipulation was also implemented
whereby participants saw eight types of test faces: 2 (same or different image) × 2 (inverted or upright) × 2 (negated or control)
The magnitude of adaptation was measured as the change in the PSE pre- to post-adaptation
Participants were randomly allocated to one of the between subjects conditions with the proviso that there was an equal number of participants in each condition (N = 12)
Participants were introduced to pictures of George Bush and Tony Blair that they would see in the experiment. The Experiment had three consecutive phases: baseline, adaptation, and test. The baseline phase involved the participants seeing all the morphs 10 times in a random order. They had to make a decision based on whether they thought the image looked more like George Bush (by pressing the G key) or Tony Blair (by pressing T key) based on the methodologies in Levitt (1971)
Each morph was on screen until the participant responded
Between each morph a 100-ms Gaussian noise mask was on screen
The purpose of this baseline phase was to discover each individual participant’s “natural” PSE
the participants were instructed to rest for 2 min and then given a 3-min irrelevant distractor task
This distractor task involved a participants filling out a questionnaire about their experiences at University
participants were presented with the adaptor image for 60 s
They were told to examine the image that was presented on screen
which was either George Bush or Tony Blair
Immediately following the adaptor, a repeat of the baseline procedure took place. However, preceding each test face, participants were presented with the adaptor for another 5 s (e.g., Hills et al., 2010). Once the test phase had been completed, participants were thanked and debriefed fully. The total experimentation time for each participant was approximately 75 min. A schematic representation of the procedure is presented in Figure 2
Those surrounded by the box are the adaptor repeated during the test phase
The magnitude of adaptation was calculated by subtracting the PSE pre-adaptation from the PSE post-adaptation. There was no effect of image identity or pair, as such the data were collapsed across these variables. Figure 3 shows the mean percentage increase in PSE in the George Busy–Tony Blair continuum for each of the test stimuli for each of the adaptor type
A positive number indicates more identity is needed to perceive the identity of the adaptor
The first analysis was a 4 (adaptor type) × 2 (orientation of test stimuli) × 2 (photographic positive/negative test stimuli) × 2 (same or different image)
This revealed a significant four-way interaction
The four-way interaction is interpreted as the three-way interaction (between orientation
and image-change) is different depending on the adaptor type
This indicates that different adaptor types affect different mechanisms
each three-way interaction for each adaptor type was analyzed
there was also a main effect of adaptor type
in which aftereffects were larger following adaptation to the negated and inverted stimuli than all other stimuli (all ps < 0.05)
Mean PSE (in identity strength needed to perceive the adapted identity) shift pre- to post-adaptation (as a measure of the magnitude of the aftereffect) for famous faces
when the adaptor is (A) upright and photographically positive
Darker bars represent upright test stimuli
lighter bars represent inverted test stimuli
Figure 3A indicates that greater adaptation occurred when the test stimuli were upright
The data were subjected to a 2 × 2 × 2 within-subjects ANOVA
This revealed that greater adaptation occurred when the same image was used for both adaptation and test
Greater adaptation was observed for upright test stimuli than inverted test stimuli
There were no significant differences in the magnitude of adaptation for negated test stimuli
There was a significant interaction between image and negation
revealing that greater adaptation was found for same image unaltered test stimuli than same image negated stimuli (mean difference = 5.31
p < 0.05) and different negated test stimuli than different unaltered stimuli (mean difference = 2.96
There was also an interaction between negation and orientation
Simple effects showed that the effect of orientation was larger for unaltered stimuli (mean difference = 14.490
p < 0.05) than for negated stimuli (mean difference = 10.577
A parallel analysis was run for when the adaptor was a negated image (Figure 3B)
This revealed a significant effect of image
whereby greater adaptation was observed when the same image was used at adaptation and test than when a different image was used
There was also a significant effect of orientation
whereby greater adaptation was observed when the test stimuli were upright than when they were inverted
There was a significant interaction between image and orientation
Simple main effects showed that the magnitude of adaptation was stronger for negated images than unadjusted images when the same image was used as the adaptor as those that made up the test morph continua (mean difference = 2.63
whereas the magnitude of adaptation was stronger for unadjusted images than negated images when a different image was used as the adaptor to that at test (mean difference = 2.79
which revealed itself in a greater magnitude of adaptation for negated upright stimuli than inverted stimuli (mean difference = 13.46
p < 0.05) which was greater than when the stimuli were unadjusted (mean difference = 10.69
A further parallel analysis was run on the data when the adaptor was inverted (Figure 3C)
whereby the same image produced greater adaptation than a different image
whereby there was less adaptation for negated images than control images
there was a significant interaction between image and orientation
revealing itself through greater magnitude of adaptation for same upright images than same inverted images (mean difference = 1.95
p < 0.05) and different inverted images than different upright images (mean difference = 2.33
A fourth analysis was run on the data for when the adaptor was both inverted and negated (Figure 3D)
whereby greater adaptation was observed when the adaptation and test stimuli matched than when they were different
There was a significant effect of negation
whereby greater adaptation was observed when the test stimuli were not negated than when they were
There was also a main effect of orientation
whereby inverted test stimuli were less adapted to than upright test stimuli
There was an interaction between image and orientation
revealing itself through a larger main effect of orientation when the test stimuli were different from the adaptor (mean difference = 16.96
p < 0.05) than when the test stimuli were the same as the adaptor (mean difference = 10.39
there was an interaction between negation and orientation
Simple effects revealed that the main effect of orientation was greater for negated test stimuli (mean difference = 14.98
p < 0.05) than for unaltered test stimuli (mean difference = 12.38
All aspects of the method were identical to Experiment 1a, except that a different set of 32 participants were recruited and were tested on unfamiliar faces. The unfamiliar faces were matched for image quality to the famous faces, but were from the NimStim Face Stimulus Set (Tottenham et al., 2002) and had been previously rated as a similar level of attractiveness and distinctiveness as the famous faces in a pretest
They were matched and morphed in the same way as in Experiment 1a
The procedure contained an extra phase when the participants were introduced to the faces (prior to the baseline)
Participants were shown each face identity (with either the letter T or G underneath) for 5 s five times
Then they were presented the faces 10 times without the letter and asked to identify the face (by pressing either T or G)
the participants were given a further 10 trials without feedback
Accuracy was above 95% for all participants at this point
the procedure was identical to Experiment 1a
The analysis protocol was identical for Experiments 1a and 1b, and the mean PSE shift is presented in Figure 4
There main effect of adaptor type was not significant
Mean PSE (in identity strength needed to perceive the adapted identity) shift pre- to post-adaptation (as a measure of the magnitude of the aftereffect) for unfamiliar faces
Figure 4 indicates that greater adaptation occurred when the test stimuli were upright (Figure 4A)
Greater adaptation was observed for photographic positive stimuli than photographic negative stimuli
revealing that greater adaptation was found for same image unaltered test stimuli than same image negated stimuli (mean difference = 5.32
p < 0.05) and different negated test stimuli than different unaltered stimuli (mean difference = 3.11
Simple effects showed that the effect of orientation was larger for unaltered stimuli (mean difference = 5.85
p < 0.05) than for negated stimuli (mean difference = 1.38
A parallel analysis was run for when the adaptor was a negated image (see Figure 4B)
whereby greater adaptation was observed when the test stimuli were upright
There were larger aftereffects in photographic positive images than negated images
There was a significant interaction between image and photographic negation
Simple effects showed that the magnitude of adaptation was stronger for negated images than unadjusted images when the same image was used as the adaptor as those that made up the test morph continua (mean difference = 3.18
and when a different image was used as the adaptor to that at test (mean difference = 1.65
which revealed itself in a greater magnitude of adaptation for negated upright stimuli than inverted stimuli (mean difference = 5.94
p < 0.05) and no difference when the test stimuli were unadjusted (mean difference = 0.88
A further parallel analysis was run on the data when the adaptor was inverted (Figure 4C)
The main effect of orientation was significant
whereby there was more adaptation for inverted images than upright images
There was a significant interaction between photographic negation and orientation
in which the aftereffects were greater when the test images were inverted than upright when they were photographic positive (mean difference = 5.45
p < 0.05) but not when the test images were negated (mean difference = 1.69
there was an interaction between orientation and image type
revealing itself through greater magnitude of adaptation for same inverted images than same upright images (mean difference = 4.83
p < 0.05) and different inverted images than different upright images (mean difference = 2.31
A fourth analysis was run on the data for when the adaptor was both inverted and negated (Figure 4D)
whereby greater adaptation was observed when the test stimuli were negated than when they were not
whereby inverted test stimuli were more adapted to than upright test stimuli
revealing itself through a larger main effect of orientation when the test stimuli were the same as the adaptor (mean difference = 4.62
p < 0.05) than when the test stimuli were the different to the adaptor (mean difference = 2.40
There was an interaction between negation and orientation
Simple effects revealed that the main effect of orientation was greater for negated test stimuli (mean difference = 5.91
p < 0.05) than for unaltered test stimuli (mean difference = 1.11
there was an interaction between photographic negation and image
whereby negated images had a larger aftereffect than positive images when the test images were the same as the adaptor (mean difference = 2.60
p < 0.05) than when the test images were different to the adaptor (mean difference = 1.12
These results indicate that the interaction between type of processing
and face-specific mechanisms (as indicated by the factors: orientation
and image-change) depends on what the adaptor is
This will be further discussed in the Section “General Discussion.” To address whether there are differences across familiarity
a five-way ANOVA combining Experiments 1a and 1b
thus containing the factors: familiarity (famous or unfamiliar faces); adaptor type; orientation (upright and inverted); negation (negated and normal); and image (same and different)
the main effect of familiarity was significant
in which aftereffects were significantly stronger for famous faces than unfamiliar faces (mean difference = 5.13)
This suggests that the mechanisms behind adaptation in famous and unfamiliar faces are different
Further discussion of this is provided in the Section “General Discussion.”
we would expect that aftereffects should not transfer so readily across adaptors of one spatial frequency distribution to test stimuli of a different spatial frequency distribution
Sixty Cardiff University students undertook this experiment as partial fulfillment of a course requirement
All participants had normal or corrected vision
All were White British nationals who were famous with the famous faces
A 3 × 3 mixed design was employed in which the type of adaptor was manipulated between subjects and the type of test stimuli was manipulated within-subjects
The experimental procedure was undertaken in the same way as Experiment 1
The data, summarized in Figure 5
were subjected to a 3 × 3 mixed-subjects ANOVA
This revealed there was an effect of the test stimuli
in which aftereffects were smaller in unaltered test stimuli than low-pass filtered test stimuli (mean difference = 3.85
There was also a main effect of adaptor type
there was greater aftereffects following adaptation to the unaltered and high-pass filtered adaptors than the low-pass filtered faces (mean difference = 5.06
p < 0.05 and mean difference = 3.79
Mean PSE (in identity strength needed to perceive the adapted identity) shift pre- to post-adaptation (as a measure of the magnitude of the aftereffect)
and high-pass filtered adaptation stimuli split by unaltered
and high-pass filtered test stimuli for famous faces
Experiment 2b was conducted in the same way as Experiment 2a
except that the faces were unfamiliar (the same as those used in Experiment 1b
A different set of 60 participants were recruited
The data, summarized in Figure 6
This revealed there was a marginal effect of the test stimuli
in which aftereffects were smaller in unaltered test stimuli than low-pass filtered test stimuli (mean difference = 2.69
there was greater aftereffects following adaptation to the unaltered than the high-pass and low-pass filtered faces
though not significantly (mean difference = 4.35
p = 0.07 and mean difference = 3.81
and high-pass filtered test stimuli for unfamiliar faces
a comparison across famous and unfamiliar faces was conducted by inputting the data into a 2 × 3 × 3 mixed-subjects ANOVA with the factors: familiarity of the face
the three-way interaction was not significant
The main effect of familiarity was significant
in which aftereffects were greater following adaptation to famous faces (mean difference = 5.24)
these results indicate that image degradation affects the FIAE famous and unfamiliar faces in a similar manner
aftereffects are greater in famous faces than unfamiliar faces
the results for famous faces are not consistent with these results (Experiment 1b)
More interestingly, adaptation to an upright stimulus does not transfer to inverted test stimuli. This suggests that during the test phase, extracting identity from the inverted faces is unaffected by adaptation. This may be because it takes longer to recognize an inverted face (Valentine, 1988) and the response to the face is made before recognition is fully made (cf.
the difference between a remember and a know response in the remember/know procedure)
The results are more intriguing when the adaptor is inverted. Here, the adaptation does transfer to upright stimuli (Figures 3B,D and 4B,D). However, the magnitude of adaptation depends on how different the test stimuli are from the adaptor. The magnitude of adaptation is smaller when there are more differences between the adaptor and the test stimuli. When the adaptor is inverted and negated (Figures 3D and 4D)
the magnitude of adaptation does not depend on degree of difference between the adaptation stimuli and the test stimulus
since greater adaptation was noted for upright test stimuli
the nature of identity adaptation is more complicated than based on visual or expert face-processing skills
One plausible explanation for the transfer from inverted adaptation stimuli to upright test stimuli may be based upon how participants process an inverted face. Extracting identity from an inverted face takes longer than in an inverted face, however, it is still completed within 5 s (Valentine, 1988) which is the length of time the adaptor was on screen for in the present study
even an inverted face can cause identity adaptation
an inverted test stimulus will not be affected by adaptation possibly because the presentation is too brief to activate the expert face recognition system
The adaptor is on screen for 5 s and which means that the early face processing could be inhibited in favor of later face processing using spatial frequencies in the lower bands
if the faces are stored more with low spatial frequencies than high spatial frequencies
This explanation can only be made hesitantly and requires further testing to see if during the adaptation phase
whether high or low spatial frequencies are employed
This is consistent with the suggestion that famous faces recruit additional brain regions that are more anterior than the fusiform gyrus
adaptation in famous faces is likely to involve more brain regions than adaptation in unfamiliar faces and lead to more robust aftereffects
This description is of course speculative and further research is required to confirm these suggestions
this method could be used to establish how different the processing of other-race faces is: if there is transfer of aftereffects from own- to other-race faces
then this suggests they are processed using similar mechanisms
If there is no transfer then the mechanisms used to process faces is likely to be different
has scope for exploring the representation of different classes of faces
these data seem to suggest two important facets of the FIAE
there is some image-based adaptation that is occurring
This is lower-level and may exist to allow for differences between stimuli to be better detected
This is based on the fact that stimuli that are matched at adaptation and at test produce stronger FIAEs than unmatched stimuli
part of the FIAE is based on face-specific mechanisms
since the FIAE is based in part on expert processing
As such FIAEs represent a unique class of high-level shape aftereffect due to expert processing involved in face processing
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest

Ana Paula Migliari / TV Brasil / EBCJoão Moreira Salles: the Institute’s initial endowment is R$20 millionAna Paula Migliari / TV Brasil / EBC
Journalist and documentary producer João Moreira Salles and Branca
announced the establishment of a private institute to support science
Institute XY (the temporary name) will operate using resources from an endowment fund through a donation of roughly R$20 million from Mr
João is a son of businessman and banker Walther Moreira Salles (1912-2001)
Endowment funds are common financing models in countries such as the United States
and they use donations that generate income that is in turn invested in research
in charge of setting up the Institute and selecting its executive director
tells Agência FAPESP that “the goal is to support research and science communication projects in mathematics and science.” The idea came about in 2010
while Salles was teaching a film course at the Pontifical Catholic University of Rio de Janeiro (PUC/RJ)
two mathematicians and 27 students with bachelor’s degrees in film
“The graduation rate for engineers in Brazil is lower than in China
India and Russia—the emerging countries with which we compete most,” he wrote in an article published in 2010 in the newspaper Folha de S.Paulo
Salles has held meetings with researchers and visited funding agencies in Brazil
such as the Fraunhofer Institute in Germany
searching for ideas to strengthen the Institute
XY is expected to begin operations in 2016

Juana Morales is cooking pupusas – thick tortillas with different kinds of fillings
a highly nutritional seed whose consumption is being promoted in the small town of San Isidro in western El Salvador
Aug 9 2016 (IPS) - Juana Morales is cooking one of the most popular dishes in El Salvador: pupusas
But hers are unique: they are not made with the traditional corn tortillas
a highly nutritional seed that has fallen out of use but whose consumption is being encouraged in rural communities
“I cook something with ojushte almost every day – pupusas
tamales (seasoned meat packed in cornmeal dough and wrapped and steamed in corn husks) orlittle cakes; it’s an excellent food,” the 65-year-old Salvadoran woman told IPS
a small town of 3,000 people in the municipality of Izalco in the western department of Sonsonate
Pupusas are made with thick tortillas and filled with beans
vegetables or pork.“In the communities there are families who don’t have enough to eat
and we can’t just sit back and do nothing.” -- Ana Morales
Juana Morales has easy access to ojushte (Brosimum alicastrum) because her daughter Ana Morales is the leading local advocate of the nutritional properties of the seed in San Isidro
thanks to the work carried out by a local organisation
Maná Ojushte is a women’s collective that emerged in San Isidro and began to promote the Maya nut tree and its seeds in 2010, an initiative that received a major boost in 2014 when it began to receive support from the Initiative Fund for the Americas El Salvador (FIAES)
a U.S.-Salvadoran environmental conservation organisation
The seeds of the Ojushte or Maya nut tree are beginning to be used in San Isidro and other communities in this Central American nation as an alternative source of nutrients for rural families
as part of projects designed to fight the impacts of climate change
the tree is found in the Salvadoran countryside
and in pre-Hispanic times it formed an important part of the diet of indigenous peoples throughout Central America and Mexico
which makes them an excellent addition to the family diet
but it has the advantage of being gluten-free and low in fat,” Ana Morales told IPS
Support from FIAES forms part of the conservation plans for the Apaneca Lamatepec Biosphere Reserve
which covers more than 132,000 hectares in 23 municipalities in the western Salvadoran departments of Ahuachapán
we have tried to link cultural aspects with the health and nutrition of local communities
which was part of our ancestral heritage,” FIAES territorial coordinator Silvia Flores told IPS
ground and packaged in quarter and half kilo bags
The ground toasted seeds can be used to make beverages or can be added to any dish
And the cooked nuts themselves can be added to raw dishes
Some 20 families harvest the seeds from farms around the community where trees have been found
They sell them to the group for 20 to 50 cents of a dollar per half kilo
depending on whether the seed is brought in with or without the shell
in the area where the Maya nuts are dried and shelled
in San Isidro in the municipality of Izalco in the western Salvadoran department of Sonsonate
This represents an additional source of income at a time when work is scarce in the countryside and climate change is jeopardising staple food crops like corn and beans
“The arrangement is that I buy the nuts from them
but they have to include them in their diet,” she said
Maná Ojushte sells 70 percent of what it produces and the remaining 30 percent is distributed free to the community
“In the communities there are families who don’t have enough to eat
and we can’t just sit back and do nothing,” said Morales
14 percent of children five and under suffered from chronic malnutrition
according to that year’s National Health Survey
which provides the latest available statistics
That is higher than the Latin American average
according to the World Health Organisation
“My family and I love Maya nuts,” Iris Gutiérrez
Gutiérrez buys buns and sells them in the village
is to learn to make bread with ojushte flour and sell it
“One day that dream will come true,” she said
She added that she goes to farms around the village to harvest the nuts and adds them to her family’s diet
collecting firewood along the way to cook them
“If we gather two pounds (nearly one kilo)
we add them to corn and the tortillas are more nutritious and our food stretches farther,” said Gutiérrez
a mother of two and the head of her household of six people
in the municipalities of Candelaria de la Frontera and Texistepeque
the United Nations Food and Agriculture Organisation (FAO) is backing a similar effort
a bush native to Mexico’s Yucatan peninsula
was also used by the ancient Mayans in the pre-Columbian era
the promotion of chaya emerged as part of environmental conservation plans aimed at combating the impacts of climate change
“Local communities had to look for a nutritional alternative that would improve the diet but would also be resistant to climate change
and we found that chaya is one of the most beneficial plants,” Rosemarie Rivas
a specialist in nutrition at the FAO office in El Salvador
as well as 8,000 moringa trees (Moringa oleifera)
also known as the drumstrick or horseradish tree
Another part of the project will be the creation of 250 family gardens to boost local food production capacity
Efforts to encourage consumption of ojushte
moringa and other locally grown plants can make a difference when it comes to lowering malnutrition rates in rural areas
that boosting nutrition is not only about eating healthy foods
by factors such as the availability of sanitation and clean water
its nice to know ojushte is being used and that native foods are making their way back into our kitchens
A little nitpick here but tamales in El Salvador are not wrapped in corn husks
