Ultra-processed foods are made to maximize cravings and encourage overeating

Ultraprocessed foods include preservatives, dyes, sweeteners, and more

Processed foods are those that have been altered from their original state, which includes numerous processes that we consider natural, such as cooking or salting. Ultraprocessed foods contain at least one item that wouldn’t be found in a kitchen, like hydrogenated oils or high-fructose corn syrup. It’s estimated that nearly 75% of all foods consumed in the US are ultraprocessed, though that doesn’t mean that all of them are unhealthy. In fact, some, such as prepackaged whole wheat bread and soy milk, are recognized for their health benefits.

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.

How the Great Depression still shapes the way Americans eat

From fortified foods to nutrition labels, the legacy of an early financial crisis lives on in kitchens across the United States. Ethnic foods with their (supposedly) hunger-triggering spices were vilified and considered “stimulants” along the lines of caffeine and so, in their stead came prune puddings, canned-meat stews, and dairy-heavy vegetable casseroles featuring America’s first fortified foods.

The dark side of modern sugar production

Humanity's ancestors evolved to wring more calories from sugary fruits by storing excess sugar as fat, an adaption that's culminated in many peoples' palettes preferring calorie-rich sweet. Now, the desire for sugar has both contributed to a widespread health crisis and been at the center of atrocities around the world.

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.)

The lack of guidance on getting off GLP-1s leaves patients at risk

Proof of 'natural' food claims are voluntary for most food products

Unlike the enforcement done by the USDA for meat, dairy and eggs, the FDA offers loose guidelines for using a "natural" food label on most foods, and following the guidelines is voluntary. As a result, many products labeled as "natural" can contain processed ingredients and synthetic additives.

The term 'superfood' is a marketing construct with no scientific or medical definition

Encompassing at least 136 plants and animals, the concept has been criticized by nutritionists for its scientific value, which has been exploited by the wellness industry for profit.

Learn about the neuroscience and psychology of why we crave comfort foods

The term was coined in 1966, when psychologist Joyce Brothers suggested humans turn to food associated with the feelings of comfort from their childhoods when experiencing emotional distress.

The gut microbiome may play a major role in autoimmune disease and symptom flare-ups

Certain unhealthy foods can promote gut bacterial growth and inflammation in the lining of the gut, potentially disrupting its lining—leading to a leaky gut that may allow pathogens to dribble out into the bloodstream, fueling further inflammation that can both cause disease flare-ups and set the stage for future disease development.

Processed foods were marketed to busy wives in the 1950s

In the 1950s, they were marketed as time-saving conveniences for young families, especially those living in the rapidly expanding suburbs, who could easily find them in local supermarkets, making them a seemingly sensible alternative to fresh foods.

GMOs sound scary, but you eat them every day

Why are GMOs bad? They aren’t. We’ve been eating them for decades with no ill effects, which makes sense, because a genetically modified organism is simply an organism, like every other organism, produces hundreds of thousands of proteins, but one or two of them are proteins that were chosen specifically by humans.

Are seed oils as bad as rumors say?

Some claim seed oils—oils extracted from seeds, such as sunflower or canola—increase inflammation and disease risk, advising consumers reach for saturated fats instead. Saturated fats, typically solid at room temperature, are found in animal products and some vegetable oils, including coconut. When adjusting for lifestyle risk factors, research shows seed oils are, on average, good for one's heart and considered healthy alternatives to saturated fat.

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).
