Most people say, "I ate that growing up, and I turned out fine." But here's the thing …more

what it claims

The modern diet has become enriched with ultra-processed products and harmful additives compared to the diet of our childhood; therefore, it is essential to read labels carefully to protect our overall health, particularly our metabolism and our microbiota.

holds up

The assertion that our modern diet is saturated with ultra-processed foods (UPFs) that are harmful to the metabolism and microbiota is widely validated by science.

The assertion that our modern diet is saturated with ultra-processed foods (UPFs) that are harmful to the metabolism and microbiota is widely validated by science. A systematic review of meta-analyses published in The BMJ (2024), covering nearly 10 million participants (a high level of observational evidence), confirms that high consumption of UPFs is linked to 32 adverse health effects. Regarding the microbiota, recent studies published in MDPI (2025) indicate that industrial emulsifiers and additives alter the intestinal barrier and reduce microbial diversity. The idea that food acts as 'information' for the body is a popular science metaphor, even though the gut-brain axis and immune interactions are increasingly well-documented. However, some scientists point out in The BMJ that the NOVA classification of UPFs sometimes lacks nuance by categorizing foods with very different nutritional profiles in the same way. Finally, the direct impact of reading labels on health biomarkers has not been the subject of randomized controlled trials (RCTs), but it remains a solid behavioral strategy recommended by experts.

More from Mark Hyman, M.D.

Test your lipoprotein (a) or Lp(a) level at least once—a genetic heart health risk factor that affects 1 in 5 people and varies little with lifestyle—in order to adjust other modifiable wellness parameters if necessary.

Integrate walking regularly into your daily life, even in short 10-minute sessions, to significantly improve your metabolic and overall health (blood sugar, circulation, brain, stress, and mitochondria), as consistency is more important than performance.

holds upMark Hyman, M.D.

To optimize blood glucose and stabilize energy, it is recommended to start the day with a high-protein breakfast, consume fiber (vegetables) and proteins before carbohydrates during meals, and take a light walk immediately after eating.

Others on this

Cutting back on the classic ultra-processed staples (soda, packaged chips, sugary cereal) remains one of the better-supported dietary levers — just without the drama: the long-term risk association is real and reproduced, not an immediate sentence for one indulgence now and then.

mixedSanta Cruz Paleo

If you use protein powder, pair it with whole foods for fiber, and choose it on quality criteria: a short ingredient list, no unnecessary sweeteners or additives, and third-party testing.

holds upThe Doctor's Kitchen

If you deep-fry often or eat restaurant fried food regularly, favor a more heat-stable oil (olive, avocado) over reusing the same oil repeatedly or pushing it to very high heat: repeated heat and reuse are the real issue, not seed oil itself.

Other advice in the Register that leans on the same research.

Consuming a Big Mac occasionally does not affect your fitness if it is part of a generally balanced lifestyle, especially since its classic ingredients and regulated additives are not inherently harmful.

holds upGraeme Tomlinson

It is preferable to favor "homemade" brownies with a short, controlled ingredient list rather than industrial versions, which are often characterized by a long list of additives deemed unnecessary.

holds upJimmy Mohamed

Food additives and "chemicals" are not the primary drivers of obesity or declining health; it is preferable to focus on physical activity, fruit and vegetable consumption, fiber, and socioeconomic determinants.
