Drone Captures Footage of an Amazon Tribe Never Seen by the Outside World

It’s estimated that there are still hundreds of uncontacted tribes remaining in the world, and footage of one of them was captured last year by a drone in Brazil’s Amazon rainforest, CBS reports.

The clip—filmed in 2017 but uploaded to YouTube this week by a Brazilian government agency called the National Indian Foundation (FUNAI)—is only 51 seconds long. In the distance, a person can be seen walking through a forest clearing in the Javari River valley, situated in northwest Brazil near the border with Peru. The agency also released photos of an ax, thatched hut, and canoes found in the area.

According to a statement from FUNAI (translated into English by Google), drone surveillance and ground inspections were undertaken to better protect indigenous groups. FUNAI found two groups of outsiders hunting illegally in the area. In addition, they discovered that a landowner and farmers had been encroaching on land reserved for indigenous peoples. These types of activities can lead to deforestation and violence against indigenous communities, according to The New York Times.

“Vigilance and surveillance should be intensified in the region to curb the actions of violators and ensure the full possession of the territory by the indigenous people,” Vitor Góis of FUNAI said in a translated statement.

The Javari Valley is home to seven contacted peoples and seven uncontacted indigenous groups, according to Survival International. Last month, the agency also released footage of a man who is believed to be the last member of a tribe in the Brazilian state of Rondônia along the Bolivian border. Officials say he has lived alone in the jungle for 22 years, ever since his village “fell victim to landowners and loggers,” CBS reports.

May Cause Anal Leakage: The Olestra Fat-Free Snack Controversy of the 1990s

When Procter & Gamble began market-testing a fat-free version of their popular Pringles snack in late 1996, Pringles brand manager Casey Keller called their attempt to revolutionize the food industry with the calorie-conscious chips “the number-one unmet consumer need” of the moment.

The chip, which had zero grams of fat and only half the calories of conventional Pringles, was made possible by Procter & Gamble’s olestra, a synthetic fat molecule marketed under the brand name Olean. Because it was too large to be absorbed by the intestine, it passed through the digestive tract—a little too quickly, as it turned out.

Olestra, which was found in Pringles and later in Frito-Lay products like Ruffles and Doritos, was burdened by a nagging problem. The miraculous fat molecule gave a percentage of consumers stomach cramps, loose bowel movements, and diarrhea. It also led to the coining of phrases not normally associated with snack foods, like “fecal urgency” and “anal leakage.”

A 25-Year-Long Journey

Olestra’s origins date back to 1968, when Procter and Gamble researchers were investigating fats that premature infants might be able to tolerate more easily. Over time, they found that attaching an increased number of fatty acids to the sorbitol molecule rendered the fats unable to pass through the mucus membrane of the intestine and were therefore totally indigestible.

Because sorbitol was expensive, researchers substituted sucrose and combined it with triglycerides. With this “fake” fat derived from cottonseed and soybean oils, they seemed to have discovered the holy grail of satiety: a greasy additive that provided flavor with zero calories, zero fat, and zero cholesterol.

The development process took 15 years. It took another 10 years for the Food and Drug Administration (FDA) to approve olestra for the so-called savory food category: potato chips, pretzels, and other salty snacks—but there were a few wrinkles. For one, olestra appeared to affect how the body absorbed vitamins A, E, D, and K. It also impacted dietary carotenoids, which may help the body ward off cancer and heart disease. The FDA insisted snacks made with olestra be supplemented with vitamins in order to offset any imbalance that ingestion might cause. The agency also mandated a package warning about abdominal cramping and loose stools, an observed side effect of olestra consumption.

Procter & Gamble made a minor stir about the label—after all, it can be difficult to market food with a warning that it might give you explosive diarrhea—but was otherwise pleased. After 25 years and an estimated $200 million in development costs, olestra was finally ready for store shelves.

Procter & Gamble started with Pringles, test marketing a fat-free version of the baked chips in Ohio in 1996. As the company was prepared to sell the ingredient to other snack companies, Frito-Lay began experimenting with it in Lay's, Ruffles, Tostitos, and Doritos that same year. Early word was encouraging, and all products went on to a national rollout in 1998.

Something's stirring

For a public weaned on the idea that dietary fats were bad, olestra caused a huge stir. Frito-Lay, which marketed the chips under the brand name Wow!, pushed the idea that the chips had just 75 calories per serving, half the calories of the regular recipe, and no fat instead of the 10 grams typical of chips. That the snacks could conceivably create bathroom emergencies was relegated to late-night talk show jokes. Procter & Gamble largely dismissed the claims, comparing the potential gastrointestinal distress of olestra to eating beans or broccoli.

But broccoli had never been demonstrated to cause an orange-yellow liquid to seep out of one’s rear end. The FDA and Procter & Gamble were inundated with 16,700 complaints from consumers that products made with olestra were giving them problems from flatulence to stained underwear. A meeting of Washington’s Center for Science in the Public Interest, which had criticized Procter & Gamble for hyping olestra, featured video testimony of people afflicted by the molecule. One claimed the cramps of snacking were comparable to the early stages of labor.

Other experiences with olestra were said to include the passing of orange-yellow “globules” of oil as well as difficulty wiping. The Center even shared a study commissioned by Frito-Lay which was meant to be confidential that demonstrated “anal oil leakage” was experienced by 3 to 9 percent of study subjects. “Underwear spotting” was present in 5 percent. A variety of gastrointestinal issues were observed in 7 percent.

The potential for leakage aside, olestra overcame much of its bad publicity. Frito-Lay sold $347 million in Wow! chips in 1998 alone. The fat-free Pringles were good for $100 million that same year. It appeared that consumers were sufficiently enticed by a lower-calorie option that they wanted to see how olestra would affect them first-hand.

High hopes and loose stool

It’s impossible to know what percentage of consumers experienced adverse effects. But it’s not hard to see why it could have proven so problematic. Unlike the practical serving sizes eaten in studies, consumers tend to binge on chips, devouring a bag at a time or in conjunction with other food. While Procter & Gamble admonished that chips were snacks, it was hard to dissuade people from seeing a bag of chips with half the calories and just eating the entire thing. Even Procter & Gamble admitted that gorging could give you loose stools and cramping.

Procter & Gamble had high hopes for olestra, projecting $1 billion in sales in 2000 and eventually an entire line of olestra-infused goods like salad dressings and desserts. But two years after its explosively profitable debut, sales were just half that, and only a few other companies like Utz and Herr’s used olestra in their products. Even after the FDA removed the label warning requirement in 2003, consumers weren’t finding runny stool all that appetizing.

Frito-Lay renamed their Wow! chips to Ruffles Light and Doritos Light in 2004. In 2009, Procter & Gamble made olestra an additive in eco-friendly paints and lubricants. Some foods are still made with olestra, though it’s no longer the industry disruptor that the company had hoped for.

Speaking of its potential in 1998, Procter & Gamble's then-chairman and chief executive John E. Pepper, Jr. believed that olestra could soon take a place of prominence among other Procter & Gamble products, like Pampers diapers. He did not mention whether he expected sales of the former would help sales of the latter.

May vs. Might: When to Use Each Word

While elementary school teachers have done a thorough job of helping us all learn when to use may instead of can, the distinction between may and might isn’t quite so straightforward.

As academic editing service Enago explains, the main difference relates to how likely it is that whatever you’re talking about will come to pass. In general, statements with may indicate higher probability than those with might. If you tell someone that you may rewatch The Sopranos, you’re confessing that there’s a pretty good chance you’ll end up doing it—a better chance than if you were to say “I might rewatch The Sopranos.”

However, there are plenty of exceptions. For one, might is the past tense of may, so you should technically never use may if your statement is taking place in the past. “I predicted that he may rewatch The Sopranos,” for example, is incorrect; what you should have predicted was that he might rewatch The Sopranos. In those cases, whoever you’re talking to would just have to infer the degree of probability.

Furthermore, since may sometimes implies permission—which explains why teachers are often rigid about making students ask “May I go to the restroom?” rather than “Can I go to the restroom?”—it can get confusing when you’re not talking about permission at all. “I may rewatch The Sopranos” could hypothetically mean that someone has given you permission to use their HBO Now account to do just that. (If rewatching The Sopranos is sounding more and more appealing with every example in this article, you should know that HBO is currently offering that series and tons of other content for free, no subscription necessary.)

According to Writer’s Digest, grammar reference book Garner’s Modern American Usage considers it incorrect to use may with negative hypotheticals at all, because it’s especially easy to misinterpret them as situations where someone’s been forbidden from doing something. For instance, if you say “Kevin may not rewatch The Sopranos,” it sounds like you’re reporting that Kevin isn’t allowed to do so. “Kevin might not rewatch The Sopranos,” on the other hand, leaves much less room for confusion.

In short, you should stick with may if you’re talking about something in the present that is likely to happen, and go with might if you’re talking about something improbable, something in the past, or something paired with negatives like not or never.
