The dark side of modern sugar production

Fake sugars may disrupt metabolic health

Alternative sweeteners such as stevia and sucralose are 100 times sweeter than common table sugar. New research suggests these "high-intensity" sweeteners significantly disrupt the composition of the gut microbiome, affecting overall health. (Some users may encounter a paywall.)

Learn the history of food science breakthroughs from the 20th century

Long after humans developed the means to produce sufficient food to feed civilizations, scientific research focused on a wide variety of objectives, such as developing methods to preserve food quality (accomplished via frozen food), speeding up cooking (leading to the microwave), and lowering the cost of sweetening food, which high fructose corn syrup provides.

The myth of sugar rushes vs. the reality of sugar crashes

It's generally accepted that sugar rushes are a myth, and that hyperactivity is a more psychological experience. However, there is real science behind the rare sugar crash that primarily impacts those with diabetes. Read this article to understand how historical and cultural factors have shaped sugar perceptions, and how low blood sugar can trigger shakiness, fatigue, weakness, and more in diabetes patients.

How our sense of taste evolves as we age

Kids are hardwired to prefer sweets over greens, with sweetness a shorthand for calorie-rich and bitter flavor warning of potentially noxious plants. This holds true even in the womb, where fetuses have been seen via ultrasound scans grimacing as their hosts consume kale capsules. As they age into double digits and beyond, their taste cells and sense of smell diminish, leading to broader and less sensitive palates.

Why processed foods can be so addictive

In recent years, many critics have voiced their concerns about the food industry and how ultra-processed foods affect our health. Despite our awareness of these issues, processed foods are still incredibly hard to remove from our diet. In this podcast by The Guardian, Dr. Chris van Tulleken explains how “junk food” is created to get us hooked, how it negatively affects us, and what we can do to improve our eating habits.

Even in recent history, adaptations to the environment drove human evolution

Through genetics, environmental pressures, and cultural influences, humans have evolved to tolerate lactose, develop varying skin pigmentation, and acquire genetic resistance to diseases like bubonic plague. The metabolic and digestive systems of Indigenous peoples have adapted to their diet, which is influenced by the availability of food and water.

Gummy vitamins have candy-level sugar—and that sweetness is linked to overdoses

A typical gummy vitamin contains about the same amount of sugar in a single serving as one Sour Patch candy. It's linked to the increase in pediatric overdoses for products including multivitamins and melatonin. Gummy formulations also degrade quickly, so they often include much higher levels of the product in each serving than the label advertises—boosting overdose risks due to this unchecked variability.

Unlike its Mexican counterpart, American Coca-Cola contains high-fructose corn syrup rather than sugar

There are a few reasons why American Coke turned away from sugar in the 1980s, but none of them are related to consumer health. This Reader's Digest article breaks down the history behind Coke's recipe change, explaining why the company continues using high-fructose cough syrup.

The evolution of the human diet

Could eating like our ancestors make us healthier? One estimate suggests prehistoric hunter-gatherer communities obtained 75% of their calories from meat and fish.

Sugar skulls are more than a sweet snack

The colorful candy combines Indigenous traditions with European confectionery techniques. Its symbolization reminds celebrants that death can be “sweet.”

The ancient Romans invented the first known artificial sweetener—it involved lead

The product was known as "sugar of lead." It was made by boiling wine in lead pots, concentrating the grapes' natural sugars and adding sweetness from the lead that leached into the grapes. The substance was used until roughly the 1880s for medicinal purposes and also to sweeten wine. (Some users may encounter a paywall.)

What happens when the population grows faster than the food supply?

Human history is shaped by our ability to feed ourselves. See how population growth is tied to farmland, and how food production’s profound environmental effect shows us the need for change.

Fiji's 'quiet' diabetes crisis

Across the Pacific archipelago of Fiji, diabetes often avoids diagnosis until amputation or death is imminent. Fiji's government has said nearly 30% of its population has diabetes, and, in 2019, related amputations accounted for 40% of the country's hospital operations. This "sugar disease" may have such a stronghold on the archipelago, which has a physically active culture that prizes locally sourced foods, due to cost, with processed foods being much cheaper than alternatives.

Diabetes is a chronic disease linked to insulin production and high blood sugar

Diabetes is a chronic, progressive disease caused by a lack of, or problems processing, the hormone insulin, leading to persistently high blood sugar. Around 90 to 95% of cases are Type 2 (chronic and caused by factors like diet and environment). The remainder are Type 1 diabetes (an autoimmune disorder).

At the beginning of the 20th century, a group of young men ate standard American food—replete with food additives like borax and formaldehyde—as part of government research to better understand food safety.

Our ancient fight-or-flight response may contribute to modern ailments

Many common modern diseases humans struggle with may in fact have their origins in our ancient fight-or-flight stress response. Long-term effects of the stress hormones cortisol and adrenaline—in this case, triggered by things like workplace stressors—can wreak havoc on the delicate internal balance of our organ systems.

Why our ancestors didn't have crooked teeth

The ancient human fossil record is filled with specimens with pretty nice teeth. So why do modern humans have dental problems? Scientists can't be certain, but one hypothesis suggests the evolutionary shrinking of the human jaw crowded our mouths,...

Watermelons were once neither red nor sweet

The gargantuan summer picnic staple has a fascinating story: 100 million tons are produced worldwide and they take up the most space of any vegetable crop in the world. But not long ago, the flesh of the melon was white and it had a bitter taste.

This 2022 study is one of the findings that prompted WHO to label aspartame as 'possibly carcinogenic'

This French study analyzed online periodic self-reported food journals from more than 100,000 people for a median of almost eight years and linked aspartame consumption to a roughly 15% increased cancer risk. It found that the people who consumed higher levels of aspartame had elevated cancer numbers—particularly breast and obesity-related cancers.

The strange endurance of consuming blood for health

Blood's importance to humanity is best summarized this way: without it, we die. This importance naturally begets assumptions about its medicinal properties, many of which appear accessible through drinking or eating the fluid connective tissue. This article details the history of blood drinking, from ancient Roman gladiators to modern-day sanguinarians.

GLP-1 drugs, first used to manage diabetes, were derived from Gila monster saliva

Scientists studying the barely-there feeding frequency of the Gila monster found its saliva had a hormone regulating blood sugar and appetite. Further research revealed this hormone resembled a human one known as GLP-1, giving rise to the modern wave of diabetes and weight-management drugs.

Ice cream’s unfrozen consistency is thanks to sugar

Making ice cream is a complex, multistep scientific process. But the treat’s scoopable, chewable consistency is due to the product’s dissolved sugar.

Synthetic opioids: a historical and clinical review

In the 19th century, researchers began synthesizing and isolating poppy plant alkaloids, leading to the invention of morphine, codeine, heroin, oxycodone, and others. These highly addictive variants eventually gave rise to illicit use and a widespread underground market, laying the foundation for the current opioid crisis.

The human cost of creating medieval monsters

The concept and creation of monsters have been used since time immemorial to communicate social norms and the consequences of breaking them. Some so-called monsters were judged as such solely due to having features that would be considered birth defects in modern times. This in-depth article explores the human cost of creating medieval monsters, many of whom were defined by a physical appearance that deviates from the expected.
