Wasps in Your Figs?

The first time I ate a fig I was about 40 years old.  I was with my husband Sam, and were staying in a little cottage on a California vineyard that we rented in Sepastopol. One day, we were in the outdoor jacuzzi, which had a big fig tree hanging overhead. So I asked the owner if we could go ahead and sample the figs from the tree. I think they were Black Mission, or maybe Brown Turkey. I didn’t know much about them back then, but either way, they were uh-mazing!

Everything on that beautiful property was edible. It was an absolutely delicious vacation – a fig feast for me!  (I was making up for a lifetime of abstinence.) I practically devoured the whole tree!  I wish I had tried them sooner in my life, because they instantly catapulted to the top of my love list of fruits. Just last week, I gave my friend a fresh fig to eat, and it was her first time eating one at age 55. She absolutely loved it! It’s never too late to fall in love with figs.

The creepy (crawly) truth about figs
Fig trees don’t flower like apple, orange or peach trees. Their flowers bloom inside the pod, which later matures into the thing we eat called a fig. Each flower then produces a single, one-seeded, hard-shelled fruit called achene, and a fig is made up of multiple achene. And it gets weirder… fig flowers bloom internally, and do not rely on wind or bees to spread their pollen like most flowers do. Instead, they rely on wasps. This is the part of the story where everyone’s least favorite summertime insects get involved and you might get grossed out. Hear me out, okay?

The fig tree cannot survive without the fig wasp to spread its DNA and likewise, the fig wasp can’t live without figs.  It’s a symbiotic relationship called “mutualism.”

Here’s how it works: the female fig wasp enters a male (inedible) fig fruit and crawls into the fig through a narrow hole called the “ostiole” which is so cramped and tight that it cuts off her wings and antenna! The lady fig wasp doesn’t know whether she’s entered a male fig or a female fig. If it’s a male “caprifig” she gets comfy and lays her eggs. The eggs hatch into larvae and grow within the fig’s petals. Male wasp offspring are born blind and flightless, yet the females still find them attractive, and hook up with them to create baby wasps. These male wasps try to hit the road immediately afterward (wham, bam, thank you ma’am!)  by eating their way out of the fig — basically by creating a tunnel to get out, but unfortunately, it’s a long one, and they end up dying inside because they can’t escape.  Sorry if this is TMI!

Female fig wasps can collect a fig’s pollen and crawl out the tunnel that their dead partners built, and fly away in search of a new fig plant to lay their own eggs in.   Now, if a female wasp enters a female fig, it’s bad news for her. She won’t be able to lay her eggs because of the stylus.  She’ll die inside that fig… but she will have delivered the pollen. Mission accomplished for fig lovers.

Some of you find this interesting, and others are probably mortified. One of my fans named Tom in Alachua, Florida wrote me recently and said that I’m not entirely right about bugs in fruits. See his comments down below.

Are you worried that figs contain wasps? I’ve eaten a million and have never seen one, other than on Google Images. (Don’t do it!)   You see, it all ends well. The female figs produce an enzyme called “ficin” which digests the wasp that entered it, thus turning the wasp corpse into pure protein inside the fig.

So, lucky for the squeamish among us, those crunchy things inside the figs are seeds of the fig, not wasp parts.  And let me diffuse one other myth:  fig jam is NOT sweet baby wasp paste!

Go ahead and visually inspect the figs to see what’s inside them and you’ll see it’s just a bunch of seeds, no critters.  Really.  Nevertheless, vegans might avoid figs for this reason… because the wasps were needed for the birth of the edible fig fruit… and also they tend to worry that the exoskeleton of the fig wasp may not be 100% digested by the ficin enzyme.  I’ve also wondered if figs could trigger allergies in people who are allergic to bees or wasps, but I’m not sure about that.

Now I want to get to the good stuff on figs, because they are pretty amazing in terms of nutrition. They are considered a superfood and they are in season right now.

I love to eat seasonal foods, ideally from my own local area and I’m fortunate enough to live in Colorado where we have an amazing Farmer’s Market in Boulder. I find that my tastes and preferences sometimes change based on the time of year and the weather, with the exception of chocolate which I eat year-round!  (Especially on stressful days.)  Anyway, fall is the very best time to find ripe, fresh figs.  Visit your local farmer’s market (if you are lucky enough to live in a warm, dry climate) or natural food store to find fresh figs in a multitude of colors and varieties.

Figs are among the oldest cultivated fruits in the world.  Ancient Egyptians and Greeks prized figs, in fact, it is thought that early Olympians wore figs around their necks as medals!  Can you imagine?  Instead of Gold, Silver, or Bronze an athlete might be awarded Black Mission, Calimyrna, or Kadota, lol!

As far as calories, it differs whether you eat fresh or dried figs.  For example, 100 gm of the fresh figs carry only 74 calories, whereas dried figs confer 249 calories.

You might not know what nutritional powerhouses these little gems are. A 2014 study in the Journal of Food Science closely examined figs and found they contain precious phenolic compounds that are antioxidants, and very good for you, such as apigenin, quercetin, rutin and luteolin. Those antioxidants are incredible for immunity, vision and the integrity of your veins (think of bulging veins from hemorrhoids). Man, my column today is really conjuring up a lot of visuals that you might have trouble “unseeing”!

Fresh or dried?  Some people like to buy fresh figs and dry them naturally, without the use of commercial sulfur additives. If you’ve wondered whether oven-drying or sun-drying is better, research has already determined this for you. According to the Journal of Agricultural and Food Chemistry (November 2011), the winner is sun-drying! This preserves the highest content of those precious phenolic compounds like luteolin, quercetin and others.

Anyway, in addition to those powerhouse antioxidants, figs are an incredible source of minerals, vitamins and fiber. In fact, figs have the highest mineral and fiber content of all common vegetables, fruits, or nuts!

Fiber
Figs are best known for their fiber content.  One medium fig contains about 1.5 grams of fiber – and I’ll bet you can’t eat only one!  A serving size is between 3-5 figs, depending on their size, and one serving contains an amazing 20% of your daily recommend fiber intake.  Why do you need dietary fiber?  Among the many reasons, it helps to keep your digestive system regulated, contributing to healthy weight management and the removal of toxins and waste from your body.  Fiber intake also helps to prevent some types of cancers including postmenopausal breast cancer.

Minerals
Figs are an excellent source of several essential minerals, including magnesium, potassium, copper, calcium and manganese.  In fact, a serving of figs contains 3% of your daily recommended potassium, contributing to healthy blood pressure management; and 5% of your daily recommended magnesium, vital to brain function and healthy sleep.

Vitamins
Figs are a good source of vitamins B6 and vitamin K, among others.

Antioxidants
The antioxidant and anti-inflammatory properties of figs have been known for years.  Figs have been studied in the Mediterranean basin, where they grow plentifully, for their anti-aging benefits.  Don’t remove the peel, though, as most of the antioxidants reside there.

Protein
One large fresh fig has about 500 mg of protein, and the dried ones have slightly more, about 620 mg. Compare that with 3 ounces of beef tenderloin which contains about 24 grams of protein.

I have two notes of caution regarding figs:
1. They contain a measurable amount of oxalates, which can trigger people who have existing kidney or gallbladder issues.

2. People with diabetes should note that fresh figs are high in fructose or fruit sugar.  Dried figs, which are concentrated, are even higher in fructose and should be avoided by folks looking to manage their blood sugar. It’s certainly a good option compared to white refined sugar, but as with all fruits, you have to consider the fructose level.

You might be asking: how do I eat figs? I prefer mine wasp-free on top of a slice of brie on crackers, lol… I’m just messing with you now about the wasps. (Please don’t worry too much about that).  Honestly, I love just munching on fresh figs all by themselves.

But you can try them halved with a drizzle of balsamic vinegar, chopped in a bowl of plain yogurt, or sliced on a goat cheese-slathered crostini.  I cut them up and add them to fresh salads, it’s so easy and delicious. They make a surprising sweet addition when added to grilled cheese sandwiches.

The flavor of figs pairs especially well with apples and pears, also in season this time of year, and you’ll find plenty of delicious recipes online containing any or all three of those delicious ingredients.  Here are a couple of my favorite recipes submitted by Michele, who works for me.

Comments from a fig-loving friend named Tom who is ‘in the know’ from Alachua, Florida
(I asked Tom of the varieties mentioned below are Genetically Modified (GMO) but he didn’t know:

Dear Suzy,
First, I am a regular reader from Alachua, and greatly enjoy your column. You present a great combination of traditional and alternative medical knowledge. I read with interest your column today on fig pollination and the role of wasps. Unfortunately, the information is almost entirely incorrect regarding the figs we will encounter or grow in the Southeast US and specifically Florida. The tiny wasp pollinator is only true for figs from the Mediterranean area. This wasp does NOT live in the United States.   There was some attempt to import the wasps for pollination in California some years ago. These wasps do not live in the Southeast.  Now, all fig varieties we encounter are self-pollinating and do not require wasps.
 
You will find the information you presented on many web sites that come from newspaper articles, etc., that are simply repeating very old misconceptions. However, if you were to investigate University Ag extensions who actually know what they are talking about, you will find an entirely different story.  
 
Here are three examples from Univ of Florida, LSU, and a leading nursery supplier of fig trees;
 
1.     “Fig cultivars recommended for Florida belong to the common types of fig and are parthenocarpic; fruit develop without pollination. Smryna and San Pedro types will not bear fruit in Florida because of the absence of Caprifigs and a wasp pollenizer(Blastophaga psenes). Because the common types of fig do not require a wasp pollinizer, the best cultivars have a closed ostiole to minimize rotting by preventing the occurrence of insects or rain water inside the fruit. 

http://edis.ifas.ufl.edu/mg214  UF IFAS extension service

 

2.     Fruits of fig trees are hollow with the flowers located inside. The eye, or ostiole, is a small opening located at the end of the fig that enables the fig wasp to enter the fig fruit for pollination. The fig wasp does not exist in Louisiana; therefore, fruit is only produced by varieties that do not require pollination. Since the opening is not needed for the fig wasp, it has been possible to select for figs that have closed or plugged eye. A closed eye on the fruit is an important characteristic for the humid South. Figs with open eyes often sour during rainy weather.
Louisiana State University Ag Center
(LSU is currently the leading developer and expert on fig trees in the South)
 
3.     We have selected and propagated over 20 self-fertile varieties suitable for home growing in the humid Southeast. Varieties requiring a fig wasp pollinator cannot be grown outside of commercial fig-growing areas in California because the fig wasp is absent. All figs suitable for the Southeast United States are self- pollinating. In addition, we suggest the group called closed eye figs. 
From “Just Fruits and Exotics, a leading nursery near Tallahassee, specializing in fruit trees. http://www.justfruitsandexotics.com/JFE/product/brown-turkey-fig/ By the way, the most common fig grown through the South is called “Brown Turkey,” a closed eye self-pollinating variety.
Sincerely
Tom Pourchot
