Organic food might be greener, but it’s not better for you

Weighing in on the ongoing debate surrounding organic versus “regular” foods, health experts explain whether organic foods offer significant health benefits. Studies suggest that organic foods have little additional nutritional value compared to...

What should you eat to help the climate?

Climate change is impacted by what we eat and what we don't eat. Did you know, for instance, that livestock accounts for 14.5 percent of the world’s greenhouse gases each year? Eating less meat and dairy and more protein-rich plants like beans,...

Greenhouse gases from farming are driven by meat

The food we eat contributes to one-third of global greenhouse gas emissions caused by human activities, according to two studies published in 2021. These emissions come from various sources along the food production chain, including transportation,...

Food companies are exploring 'GLP-1 friendly' diet labels

Producers of foods like Healthy Choice frozen meals are placing "GLP-1 friendly" labels on their food, but there's no regulation about what that label means. Nutritionists say that GLP-1s can help reduce appetite, but healthy, balanced diets are a necessary complement to the medications. Data shows that about half of GLP-1 users quit these medications within a year and then rapidly regain weight, underscoring the importance of also prioritizing healthy eating.

Should you eat an all-meat diet?

The carnivore diet is reportedly a way of eating inherited from human ancestors, a tale that has roots in anthropology's early days. This article explores the all-meat diet's ancestral claims and what happens if you cut vegetables and fruits from...

What’s the best way to reduce climate impact of food?

Food is a big part of everyone’s carbon footprint, and it’s important to understand the impact of our personal food consumption. Individual food choices can emit as many greenhouse gases as personal electricity use. Plant-based diets generally...

As of 2025, perfect synthetic replication of natural organs remains elusive

Advancements such as 3D printing muscles, performing vaginal reconstruction with colon tissue, and growing organs in a lab have shown promise, but artificial options and transplanting substitutions continue to exhibit functional and performance limitations compared to their natural equivalents.

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. Watch this 11-minute video for more.

The USDA does not claim that organic food is healthier than the alternatives

Although many believe organic food to be healthier, the USDA's organic label refers to methods used to grow the food rather than any potential health benefits. Still, a 2016 Pew Research Center study found that 76% of people purchased organic food for its health value.

This 'Science Vs' episode checks the taste, health, and environmental claims about organic food against the actual research.

Health food broke into the mainstream by the 1980s

A 1984 New York Times story noted that Americans were eating less red meat than a decade prior, and that, in general, the country was “talking, thinking and worrying about what they eat to a degree unique in the nation's history.” The feature then details foods that were then considered bizarre: whole-grain muffins, hummus, and a variety of vegetarian dishes. (Some readers may experience a paywall.)

Beanless 'coffee' is an eco-friendly alternative

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.

What constitutes a 'healthy' diet?

A natural diet, typically high in plant-based foods and low in processed foods, appears to be the main contributor to a healthy, diverse gut microbiome.

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.

The nutrients vegetarians and vegans need to keep in mind

Although most older Americans still enjoy their steaks and chicken, an estimated 2.5 million of those ages 55 and older have abandoned red meat and poultry in favor of a predominantly plant-based diet. Some people decide to go vegetarian or vegan...

Biohacking to boost personal health has become a concept that encompasses everything from vitamin regimens and cryochambers to brain implants and red light therapy.

Vegan cheesemaking relies heavily on nuts and seeds

We might associate vegan cheese with current health trends, but there’s actually been a small-but-growing market for plant-based cheeses since the 19th century. But for vegan cheeses to appeal to a wider demographic, they have to compete with the familiar flavors and textures of dairy cheeses.

Feeding grazing cattle seaweed cut their methane emissions by almost 40%

The largest share of the 12% of global greenhouse gas emissions from livestock comes from methane released when cows burp. A study found that introducing a seaweed supplement in pellet form significantly reduced these emissions without affecting cattle's health or weight.

Explore the water footprint of producing various proteins, fruits, and vegetables

This interactive gallery highlights the various types of water behind the production of biofuels, foods, and materials such as cotton. Diets high in bovine meat, whose production requires 15,415 liters of water per kilogram (1,847 gallons per pound), are among the most water-intensive, whereas every kilogram of vegetables uses 322 liters of water (39 gal/lb) to produce.

The new phenomenon of 15-minute lab-grown diamonds

In 2024, scientists developed a groundbreaking method to create diamonds at normal room temperature and pressure. This efficient and simple process contrasts with the traditional high-pressure, high-temperature method. While limitations still exist, such as minuscule sizes, this discovery moves us toward an exciting new era in diamond synthesis. Check out the article for further information about how diamonds are made.

Collagen supplements typically come from animal sources like fish, pigs, or cattle

Eating collagen-rich foods won't lead to more collagen in the body because your digestive system breaks down consumed collagen into amino acids. Instead, eating a healthy diet of proteins and greens helps your body to produce collagen. Collagen supplements derived from animal skin and bones are typically sold in a prebroken-down peptide formulation called hydrolyzed collagen so they can be absorbed through the gut into the bloodstream.

Alpha-gal allergy is a problem for red meat lovers, and that same alpha-gal sugar is an issue for xenotransplants, too—since it's present in pigs, human bodies reject pig-to-human transplants as foreign once they detect the substance.

Scientists William Russell and Rex Burch proposed in 1959 that when it comes to animal testing, there should be 'three Rs'—replace animals wherever possible; reduce their numbers; refine how they're treated.

Compared with plant-based milks, cow milk produces greater carbon emissions, requires more land, and uses more water, but it naturally provides greater nutritional benefits.

Some animals, including certain tropical ants, have little or no microbial populations in their gut, upending the idea that all animals rely on this ecosystem to help maintain their health and proper functioning.

'Diet for a Small Planet' popularized the vegetarian diet

Frances Moore Lappe’s 1971 book provided recipes for vegetarian dishes, introducing millions to soy, sprouts, and tofu. It also argued that a vegetarian diet was a political act that could solve world hunger by redirecting food from livestock to humans.

The health benefits of matcha tea

Matcha tea has skyrocketed in popularity in recent years. Very likely due to its bright green color, which is conducive to social media post aesthetics. The tea is a powdered form of green tea, and its benefits are touted everywhere. This article examines the evidence for such health claims, finding the tea's key nutrients of theanine, chlorophyll, and caffeine did have small observable effects on study participants.

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. Although the label has encouraged the consumption of fruits and vegetables, food variety and minimal processing remain key to a healthy diet.

The unexpected return of the steakhouse

Although the 2010s and early 2020s saw fewer people eating red meat, the momentum has now swung in the opposite direction, with vegetarian spots closing and hip new restaurants slinging beef. Food writer Bettina Makalintal makes sense of the sudden shift by unpacking the steakhouse's resurgence.

At-home genetic testing results commonly led users to healthier lifestyles

Italian research that aimed to investigate what people do longer-term after receiving direct-to-consumer genetic test results indicated that whether the results were positive or negative, people tended to adopt a healthier diet after receiving the results, and they'd still maintained it a year after receiving their results. Some users also reported an overall reduction in stress over their health concerns. (Some users may encounter a paywall.)

Imagining the farms of the future

About 10,000 years ago, humans began to farm. This agricultural revolution was a turning point in our history and enabled the existence of civilization. Today, nearly 40 percent of our planet is farmland. Spread all over the world, these lands are the pieces to a global puzzle we're all facing: in the future, how can we feed every member of a growing population a healthy diet? Brent Loken investigates in this seven-minute video.

The ABCs and FAQs on GMOs from the WHO.

GMOs (or genetically modified organisms) are a subject of great debate in the food world…but how come? GMOs are organisms whose genetic materials have been altered in a way that does not occur naturally in order to create a product that has a...

A quarter of Gen Z eats organic food

A 2025 YouGov poll found that 25% of Gen Z US adults eat organic food, while 10% say they follow a whole-foods diet, meaning they seek out foods that are minimally processed.

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.

In 2026, University of Cambridge researchers reported that a group of gut bacteria called CAG-170 may be a key marker of good health, occurring far more often in healthy individuals and less commonly in people with chronic diseases.

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.

Organoids: 3D organs grown from stem cells in the lab

An organoid is a three-dimensional construct composed of multiple cell types that originate from stem cells that can simulate the architecture and functionality of native organs. One big benefit of these lab-grown organs is that drug candidates can be tested in model systems without needing live patients.

ConsumerLab is a watchdog site reviewing supplements for quality and recalls

The group purchases supplements and tests them for accuracy. When it tested 26 popular B vitamin supplements, it found five failed their tests because they provide either significantly less or much more of the ingredients than listed. This type of product-label mismatch can occur because the FDA does not regulate these products as it would a drug.

Meet six commercially available synbio products

An article exploring the science behind synbio products currently on the market, and projecting the products that can be expected over the next 10 years.

Most Westerners don't need more protein, despite the protein boom

You can find the macronutrient in snack bars and pretzels, shakes, and more, even though most normal diets in the West are already protein-heavy with meat and milk. A mix of increased exercise culture and influencer sway has led to a market hungry for it.

How the microbiome affects your health

The gut microbiome is so influential to overall human health that some researchers consider it a separate organ. Its conditions, influenced by environmental and lifestyle factors such as medication and exercise, contribute to immunity, metabolism, inflammation, medical treatment efficacy, brain development and function, and the development of disorders and diseases, including asthma, depression, inflammatory bowel disease, and Alzheimer's.

Scientists have created a cell from scratch—called a SpudCell—proof-of-concept work that a lab-made cell can feed, grow, and replicate like a natural cell.

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

Often disguised as healthy options like granola bars and low-fat yogurt, these foods silently fuel chronic diseases, despite dominating diets. Reviewing labels for ingredients like stabilizers and emulsifiers can serve as indicators to help identify these products.

Pig organ transplants are apparently kosher—you just can’t eat them

Science writer Mary Roach speaks with journalist Terry Gross about her latest book, “Replaceable You: Adventures in Human Anatomy” and discusses topics including why pig organs have become of such interest and what religious leaders have told her about pig organs and compliance with Jewish dietary law.
