In Memory of Dr. Jane Goodall

 


The beginning of citrus season this year coincided with the recent passing of ethologist, primate researcher, conservationist, and peacemaker Jane Goodall. She was 91 years young and died of natural causes.  One of the great secrets to her longevity came from her deep alliance with chimpanzees in their natural habitat, gleaning insights into their ability to thrive in the deep wilderness. The first "secret," of course, is no secret at all: we come from the wilderness, and nature immersion--even just simple time under a tree--is very, very, good for us. After spending years in the Gombe Stream National Park in Tanzania immersed in chimpanzee research, Jane Goodall spent much of the latter half of her life doing just the opposite: she traveled extensively, making speaking appearances on behalf of environmental conservation and world peace. In 2024, she told Reader's Digest: "A happy day for me is if I can be out in nature somewhere. If I go to a hotel and there's one tree, I will sometimes move my bed around so I can just be there and see the tree." In fact, she was on a speaking tour at the time of her death, and as of the date of this blog, she has an October 7 appearance posted on the Jane Goodall Institute's website.


The Healthy Eating Link

Nature immersion wasn't the only component contributing to Dr. Goodall's legacy.  She was also a staunch vegan and whole foods advocate, and citrus was a major part of her diet.  While the chimpanzees she lived with were omnivores and thus consumed some meat, she observed that fruit--and particularly oranges--were a major component of their daily food consumption. Second only to humans, chimpanzees are the longest-living primates, and their diets can give a clear insight into our own longevity strategy.

The Stress Connection

Dr. Goodall was also accomplished at managing her stress levels, even in the face of increasing environmental devastation and other threats to her beloved chimpanzees, other animals, and humanity.  She discovered that chimpanzees are subject to the same capacity for happiness and grief as we are. Environmental factors, encroachment, disease, and other stressors can seriously impact a chimp's health and longevity. Oranges are a huge ally here: their high Vitamin C content reduces the "stress hormone" cortisol, and the high folate and niacin concentrations found naturally in oranges function as mood-boosters.  Dehydration can also be a significant, under-acknowledged source of physiological stress; oranges and other citrus fruits are like little hydration-balls, packed with easily absorbable water in every delicious bite. It is no surprise, then, that oranges are a primary component of chimpanzee diets, and why Dr. Goodall likewise consumed them regularly.

The Happiness Link

While humans, chimpanzees, and all animals are subject to stress and mood depletion, nature gives us tools to overcome them and return to a baseline of general happiness.  One of these tools is oranges and most citrus fruits in general; this fact sheds yet another light on why both Dr. Goodall and her chimpanzee friends were so enthusiastic about eating oranges. Research has shown that eating citrus lowers the risk of depression because it stimulates the growth of a "good" gut bacterium called Faecalibacterium prausnitzii. These beneficial bacteria influence the production of the neurotransmitters serotonin and dopamine; both of these are well-known to be mood elevators. 

Sharing Is Caring

Finally, Dr. Goodall discovered that chimpanzees, just like humans, derive health and happiness from meaningful friendships and family bonds that use touch, meal sharing, and regular communication to foster connection. Sharing food is one of our most basic and powerful forms of expressing love. When we give, receive, and share healthy foods, we are expressing how much we care for and love being cared by each another.  

As we enter into a new year of citrus harvest, Florida Fruit Shippers wants to acknowledge with deep appreciation the work and legacy of Dr. Jane Goodall. We strive to continue to support the importance of her work by bringing you the benefits of citrus fruits directly from the trees.
