Thanks to a Wet Winter, New Zealand Faces a Potential Potato Chip Shortage

New Zealand has plenty of unique and tasty snacks, but kiwis also love potato chips. The universal comfort food is in danger Down Under, however, as an unusually wet winter has devastated the island country’s tuber crops, according to BBC News.

Twenty percent of New Zealand’s annual potato crop was wiped out from a series of major storms and floods that ravaged the nation’s North and South Islands, The Guardian reports. In some regions, up to 30 percent of potato crops were affected, with the varieties used to make chips bearing the brunt of the damage.

Potato prices spiked as farmers struggled, but the crisis—now dubbed “chipocalypse” by media outlets—didn't really make the mainstream news until supermarket chain Pak’nSave posted announcements in potato chip aisles that warned customers of a salty snack shortage until the New Year.

Pak’nSave has since rescinded this explanation, claiming instead that they made an ordering error. However, other supermarket chains say they’re working directly with potato chip suppliers to avoid any potential shortfalls, and are aware that supplies might be limited for the foreseeable future.

New Zealand’s potato farming crisis extends far beyond the snack bars at rugby matches and vending machines. Last year’s potato crops either rotted or remained un-harvested, and the ground is still too wet to plant new ones. This hurts New Zealand’s economy: The nation is the world’s ninth-largest exporter of potatoes.

Plus, potatoes “are a food staple, and this is becoming a food security issue as the effects of climate change take their toll on our potato crop,” says Chris Claridge, the chief executive of industry group Potatoes New Zealand, according to The Guardian.

In the meantime, New Zealanders are preparing to hunker down for a few long months of potential potato peril—and according to some social media users, kale chips are not a suitable alternative. “Chipocalypse” indeed.

The Great Tryptophan Lie: Eating Turkey Does Not Make You Tired

While you’re battling your cousins for the best napping spot after Thanksgiving dinner, feel free to use this as a diversion tactic: It’s a myth that eating turkey makes you tired.

It’s true that turkey contains L-Tryptophan, an amino acid involved in sleep. Your body uses it to produce a B vitamin called niacin, which generates the neurotransmitter serotonin, which yields the hormone melatonin, which helps regulate your sleeping patterns. However, plenty of other common foods contain comparable levels of tryptophan, including other poultry, meat, cheese, yogurt, fish, and eggs.

Furthermore, in order for tryptophan to produce serotonin in your brain, it first has to make it across the blood-brain barrier, which many other amino acids are also trying to do. To give tryptophan a leg up in the competition, it needs the help of carbohydrates. Registered dietitian Elizabeth Somer tells WebMD that the best way to boost serotonin is to eat a small, all-carbohydrate snack a little while after you’ve eaten something that contains tryptophan, and the carbs will help ferry the tryptophan from your bloodstream to your brain.

But Thanksgiving isn’t exactly about eating small, well-timed snacks. It’s more about heaps of potatoes, mountains of stuffing, and generous globs of gravy—and that, along with alcohol, is more likely the reason you collapse into a spectacular food coma after your meal. Overeating (especially of foods high in fat) means your body has to work extra hard to digest everything. To get the job done, it redirects blood to the digestive system, leaving little energy for anything else. And since alcohol is a central nervous system depressant, it also slows down your brain and other organs.

In short, you can still hold turkey responsible for your Thanksgiving exhaustion, but you should make sure it knows it can share the blame with the homestyle mac and cheese, spiked apple cider, and second piece of pumpkin pie.

How Mammoth Poop Gave Us Pumpkin Pie

When it’s time to express gratitude for the many privileges bestowed upon your family this Thanksgiving, don’t forget to be grateful for mammoth poop. The excrement of this long-extinct species is a big reason why holiday desserts taste so good.

Why? Because, as Smithsonian Insider reports, tens of thousands of years ago, mammoths, elephants, and mastodons had an affinity for wild gourds, the ancestors of squashes and pumpkin. In a 2015 study published in the Proceedings of the National Academy of Sciences, a Smithsonian researcher and colleagues found that wild gourds—which were much smaller than our modern-day butternuts—carried a bitter-tasting toxin in their flesh that acted as a deterrent to some animals. While small rodents would avoid eating the gourds, the huge mammals would not. Their taste buds wouldn't pick up the bitter flavor and the toxin had no effect on them. Mammoths would eat the gourds and pass the indigestible seeds out in their feces. The seeds would then be plopped into whatever habitat range the mammoth was roaming in, complete with fertilizer.

When the mammoths went extinct as recently as 4000 years ago, the gourds faced the same fate—until humans began to domesticate the plants, allowing for the rise of pumpkins. But had it not been for the dispersal of the seeds via mammoth crap, the gourd might not have survived long enough to arrive at our dinner tables.

So as you dig into your pumpkin pie this year, be sure to think of the heaping piles of dung that made the delicious treat possible.
