5 Key Concepts
Ultra-Processed Food (UPF)
UPF is defined as any food processed industrially and created for big-business profit rather than to provide nutrients. A simple test is if it's wrapped in plastic and has at least one ingredient you wouldn't find in a home kitchen, or if it makes a health claim on the packet.
Processing vs. Ultra-Processing
Processing is ancient and normal, involving techniques like cooking, canning, smoking, or grinding, which humans have done for millennia. Ultra-processing is new, exclusively industrial, and focuses on making products convenient, easily marketed, addictive, and very profitable by breaking down ingredients and reassembling them with industrial additives.
Food Addiction
Ultra-processed food can be addictive, similar to other substances, as evidenced by MRI data and behavioral patterns. This is because UPFs are industrially processed for rapid delivery of rewarding molecules (sugar, fat, protein) into the gut, bypassing normal satiety signals and causing physiological stress.
Satiety Mechanism
This is a complex system of hormones and nerve signals that tells the body when it's full. Ultra-processed foods are designed to bypass this mechanism, being pre-digested and absorbed in parts of the gut that don't release fullness signals, leading to excess consumption.
Metabolic Confusion
This occurs with non-nutritive sweeteners, which deliver a sweet taste without the expected sugar. This mismatch between expectation and what actually arrives causes physiological stress, potentially leading to elevated blood sugar and not being superior to sugar for weight or metabolic health in the long term.

UPFs are most of what we eat and are now considered the leading cause of early death globally, ahead of tobacco, driving cardiovascular disease, metabolic disease, and early death. They are also a leading cause of environmental destruction and carbon emissions.
Yes, even if you are at a healthy weight, consuming UPFs still leaves you vulnerable to a wide range of harms including type 2 diabetes, heart disease, dementia, anxiety, depression, inflammatory bowel disease, and cancers, as studies adjust for weight gain.
Willpower is often overemphasized; population-wide weight gain correlates with changes in the food environment, not a sudden lack of willpower. The food environment, with its affordable and addictive UPFs, makes it incredibly difficult for individuals, especially those with fewer resources, to make different choices.
Food companies are primarily driven by profit, not nourishment. They invest massive marketing budgets and use sophisticated design processes to create convenient, addictive products from commodity ingredients, making it challenging for consumers to choose healthier options.
Artificial sweeteners like aspartame and SSL-Fame-K cause metabolic confusion by signaling sweetness without delivering sugar, which can elevate blood sugar and does not seem to lead to weight loss or better metabolic health compared to sugar. Phosphoric acid in diet drinks can also dissolve teeth and leach minerals from bones.
Stress and emotions often drive negative health behaviors, and ultra-processed food is one way these harms manifest. People under stress typically binge on UPFs, not whole foods, because these products are specifically designed to hack appetite and provide rapid physiological reward.
31 Actionable Insights
1. Reduce UPF Intake Regardless of Weight
Aim to reduce your consumption of ultra-processed foods (UPFs), even if you are at a ‘healthy weight,’ as high intake still leaves you vulnerable to various health harms like type 2 diabetes, heart disease, and dementia.
2. Avoid Ultra-Processed Industrial Diets
Focus on avoiding an ultra-processed Western industrial diet, as it is the only dietary pattern consistently associated with disease, unlike diverse traditional diets.
3. Prioritize Home Cooking
Make an effort to cook at home, as this practice, regardless of specific ingredients, generally provides a significant health benefit compared to consuming industrially produced foods.
4. Reprioritize Food Shopping & Cooking
Consider reprioritizing food shopping and cooking as a vital and enjoyable part of your daily routine, as this can be a foundational step towards positive societal change regarding food.
5. Choose Whole Food Breakfasts
Opt for whole food breakfasts like porridge with fruit and milk to get essential nutrients without the risk of overconsumption associated with ultra-processed cereals.
6. Undertake a 2-3 Week Whole Food Diet
If struggling with chronic symptoms, try adopting a whole food diet for two to three weeks to observe potential improvements in mood, energy, sleep, and various physical ailments.
7. Swap Kids’ Drinks to Milk/Water
For children, make the single most impactful health intervention by switching all their drinks to milk and water, avoiding other beverages like colas or supplement drinks.
8. Identify UPFs by Ingredients
Check if a food product is wrapped in plastic and contains at least one ingredient not found in a home kitchen, as this indicates it is an ultra-processed food (UPF).
9. Be Wary of Health Claims
Be cautious of food products that make health claims on their packaging, as this ironically makes them even more likely to be ultra-processed foods (UPFs).
10. Direct Shame Towards Corporations
Understand that the prevalence of ultra-processed foods is not your fault; direct any feelings of shame or guilt outwards towards corporations whose profit motives drive the production of these addictive products.
11. Shop with an Activist Mindset
View your food shopping as an ‘activist project’ by consciously choosing not to financially support companies that produce ultra-processed foods, which harm both human health and the environment.
12. Reframe Food Preparation
Reframe food preparation as a core, essential human activity rather than a hassle, recognizing its role in connecting you to heritage, family, and community.
13. Schedule Food Preparation Time
Actively schedule time for food preparation in your daily routine, treating it as an important appointment to ensure it happens consistently.
14. Play Music While Cooking
To make food preparation more enjoyable, put on music while in the kitchen, transforming the task into a more pleasant and engaging experience.
15. Plan Grocery Shopping
Plan your grocery shopping in advance and visit larger supermarkets or markets to access a wider variety of non-ultra-processed foods.
16. Choose Real Bread
Opt for ‘real bread’ made with only water, wheat, and salt, avoiding supermarket breads that often contain numerous industrial ingredients and additives.
17. Avoid Artificial Flavors/Sweeteners
Be aware that artificial flavors and non-nutritive sweeteners can ’lie’ to your body by signaling the arrival of nutrients that don’t materialize, potentially causing physiological confusion.
18. Drink When Thirsty, Eat When Hungry
Be mindful of your body’s natural hunger and thirst signals, as ultra-processed foods and drinks are designed to encourage consumption beyond these natural cues.
19. Consider UPF Abstinence if Addicted
If you have a problematic relationship with ultra-processed food that feels like an addiction, consider abstinence from these products, similar to how one might approach alcohol or tobacco addiction.
20. Stop Forbidding UPFs
To potentially reduce cravings and develop a sense of disgust towards ultra-processed foods, try not to forbid them, but rather consume them mindfully while learning about their nature.
21. Experiment with Mindful UPF Consumption
For a few days, consume an 80% ultra-processed food diet, mindfully reading ingredient lists and serving takeaways on proper plates with cutlery, to potentially foster a sense of disgust and reduce desire for these foods.
22. Use Person-First Language
Use person-first language (e.g., ‘people who live with obesity’ instead of ‘obese people’) to reduce stigma around diet-related diseases and emphasize that conditions are not an identity.
23. Maintain Open Mind on Diets
Be open-minded to the idea that people can thrive on various traditional diets, as long as they are not ultra-processed Western industrial diets, which are the only ones consistently linked to disease.
24. Improve Diet with Minimal Risk
Be confident in making dietary improvements, as there is virtually no risk of harm associated with shifting towards a healthier eating pattern.
25. Combine Weight Loss Drugs with UPF Reduction
If using new weight loss drugs like semaglutide, ensure you also reduce ultra-processed food consumption, as these drugs may prevent weight gain but won’t protect against other harms of UPFs.
26. Offer Raw Produce Before Dinner
Give children raw fruit and vegetables before dinner, especially when they are bored or watching television, as they are more likely to eat it and reduce consumption of less healthy options.
27. Limit Pre-Dinner Snacks for Kids
Prevent children from eating excessive ‘rubbish’ (unhealthy snacks) before dinner to ensure they have an appetite for a wholesome meal of fish, meat, and vegetables.
28. Discuss Food with Children Early
Engage children in conversations about food and nutrition from a very young age to help them understand healthy choices and develop agency in their eating habits.
29. Allow UPFs at Children’s Parties
When children attend parties, allow them to consume ultra-processed foods without restriction to help them fit in and avoid feeling ‘weird’ among peers.
30. Charge Phone Outside Bedroom
Charge your phone outside the bedroom to avoid the temptation of doom-scrolling and potentially gain an extra half-hour of sleep each night.
31. Become an Anti-UPF Activist
If you are inclined, consider becoming an activist against ultra-processed food corporations, understanding that your purchasing choices support a system causing environmental destruction and health harms.
6 Key Quotes
Ultra-processed food is now the leading cause of early death on planet Earth, ahead of tobacco.
Dr. Chris Van Tulleken
If it's wrapped in plastic and has at least one ingredient you wouldn't find in a home kitchen, it's a UPF. If it makes a health claim on the packet? Ironically, it's even more likely!
Dr. Chris Van Tulleken
The food supply system exists to extract money from you, to supply money from you to intermediate food processes and ingredients companies. That's its function.
Dr. Chris Van Tulleken
The only diet we've ever studied that's associated with disease is an ultra-processed Western industrial diet.
Dr. Chris Van Tulleken
If you are minded to be an activist, and by the way, this hypothetical 45-year-old mum of three will need a lot of resources if they're to stop buying lots of ultra-processed food because their life will become more expensive. But knowing that they are supporting a system that is causing environmental destruction, carbon emissions and so on, I think is really important.
Dr. Chris Van Tulleken
People only eat when they're hungry and only drink water to thirst. So if you can find a way of getting people to drink more liquid than they feel thirsty for and eat more food than they feel hungry for, that's the purpose of ultra-processing.
