- Milk pasteurization is a meals processing follow that retains dairy meals protected. Exposing contemporary milk to warmth kills dangerous micro organism accountable for ailments like listeriosis, tuberculosis and typhoid fever.
- Meals fortification (the addition of vitamins to frequent meals) is a meals processing technique that helps cut back nutrient deficiencies within the inhabitants. It began with including iodine to desk salt in 1924 to cut back the danger of goiter, and now consists of issues like vitamin D fortification of dairy meals and the addition of B nutritional vitamins to many grain meals.
- Packaging and preservation are meals processing strategies that assist retain the nutrient high quality of vital meals. For instance, frozen fruits and veggies have been proven to have greater nutrient content material than their contemporary counterparts on account of nutrient losses that happen in contemporary produce throughout transport and storage.
Nonetheless, there are many meals objects processed to be low cost and scrumptious that don’t have anything to do with enhancing well being. That is the place the dialog about ultra-processed begins.
What are Extremely-Processed Meals?
Extremely-processed meals are usually outlined as merchandise that bear a number of processing steps, leading to objects loaded with components and missing dietary worth. These meals are often excessive in sugar, fats and sodium, and low in fiber, making them basic examples of junk meals like comfortable drinks, chips, scorching canines and cookies.
Nonetheless, well being researchers have expanded this definition utilizing a classification system known as NOVA. NOVA evaluates a meals’s elements to gauge the extent and intent of processing. Based on NOVA, sure breakfast cereals, granola bars, child components, frozen meals and sliced bread are thought of ultra-processed—meals that many depend on for a balanced weight loss program.
This highlights a key criticism of the NOVA framework. It solely focuses on meals processing, ignoring a meals’s nutrient worth. This simplistic strategy falsely suggests that each one processed meals lack vitamins, which is inaccurate. Thus, nutrient-rich protein shakes is likely to be bucketed alongside objects like jelly donuts regardless of their vastly completely different dietary profiles and results on well being.
The takeaway: there’s no consensus on the definition and relevance of ultra-processed meals. Till additional analysis considers issues like nutrient content material, we must always not use “ultra-processed” terminology to label meals as inherently unhealthy.
That mentioned, many specialists acknowledge that meals processing impacts our well being to some extent, and ongoing analysis is deepening our understanding of this relationship.
Extremely-Processed Meals and Well being
Utilizing the NOVA framework, it’s estimated that ultra-processed meals account for round 57% of the full energy within the common US grownup’s weight loss program.
A number of research have observed that individuals who eat a variety of ultra-processed meals even have greater dangers of growing ailments like weight problems, coronary heart illness, irritable bowel syndrome, melancholy, dementia and most cancers.

They simply present that they’re occurring on the similar time. Nonetheless, there are a number of theories about how they is likely to be associated, together with the next:
- Extremely-processed meals with a number of saturated fat, added sugars and flavor-enhancing chemical substances could substitute extra nutrient-dense meals, resulting in poor diet consumption.
- Meals packaging supplies could comprise chemical substances that disrupt hormone regulation.
- Sure meals’ publicity to meals processing strategies (e.g., fats to excessive warmth) may create byproducts poisonous to well being.
Whereas these theories are fascinating, solely one small experimental research has investigated these potential relationships.
On this research, 20 wholesome volunteers spent a month in a diet lab. Throughout this time, they have been randomly given a weight loss program of ultra-processed meals or a weight loss program of minimally processed meals as outlined by the NOVA framework. Diets have been matched for calorie content material, however contributors weren’t instructed how a lot to eat.
For example, the ultra-processed breakfast included a bagel with cream cheese and turkey bacon, whereas the minimally processed breakfast was oatmeal, fruit, nuts and skim milk.
After two weeks, contributors switched diets. The ultimate outcomes indicated that when consuming ultra-processed meals, contributors ate extra (about 500 extra energy per day) and gained weight. This led researchers to conclude that one thing about processed meals causes elevated calorie consumption and weight acquire.
Nonetheless, it must be famous that whereas energy between the diets have been the identical, diet wasn’t. The ultra-processed weight loss program group acquired much less fiber and protein and extra added sugars–vitamins related to urge for food management.
Finally, extra analysis is required earlier than these insights turn out to be diet suggestions. So what will we do with this data now?
