The USA has updated its new dietary recommendations for the years 2025–2030 – and these adjustments are significant. For the first time, the focus clearly shifts to real, unprocessed foods such as protein sources, vegetables, fruit, healthy fats, dairy products and whole-grain products. At the same time, a marked reduction of refined sugar, white flour, highly processed products and industrial additives is recommended.
This change of course is justified by the increasing burden of chronic diseases, whose connection with nutrition is today documented ever more clearly. These adjustments possibly signal more than a purely technical update – they could be an indication of a fundamental shift in our understanding of healthy nutrition.
What exactly was adjusted? The most important innovations at a glance
Several aspects stand out and differ markedly from earlier recommendations:
- A clear focus on protein
Protein is given a central role and is emphasised at almost every stage of life. A daily intake in the range of 1.2–1.6 g per kilogram of body weight is recommended, which is remarkably high for official guidelines. In addition, broad coverage across animal and plant sources is recommended.
- Full-fat dairy products instead of low-fat
For the first time, it is recommended to consume full-fat dairy products without added sugar. Low-fat variants thereby lose their decades-long status as the standard option.
- Healthy fats are rehabilitated
A wide range of natural fat sources is presented positively – including eggs, fish, nuts, seeds, olives, avocado, butter and other animal fats. The traditional “fear of fat” loses significance. At the same time, it is noted that the optimal composition of fatty acids should be researched further.
- A clear stance against highly processed products
A particularly strong point: Ultra-Processed Foods should be consistently reduced. These include:
- soft drinks and sweetened beverages
- packaged snacks
- confectionery
- ready-made products
- convenience food
- heavily processed grain products
- light and diet products with artificial additives
Artificial sweeteners, colourings and preservatives are also assessed critically.
- Hydration and electrolytes
The explicit recommendation to ensure adequate hydration and electrolyte supply appears interesting and modern – especially for physically active people and those who do sports.
- A significantly reduced carbohydrate share
If one considers the overall recommendations, the result is a form of nutrition that strongly resembles Low Carb, LOGI or even, with certain adaptations, ketogenic approaches – especially in the case of metabolic diseases. For people with diabetes, for example, explicit reference is made to the possible benefits of a carbohydrate-reduced diet.
Why is this update regarded as a possible turning point?
For the first time in several decades, proteins and healthy fats move to the centre, while refined carbohydrates, sugar and industrial products are deliberately pushed back.
In this way, several widespread societal nutritional assumptions are indirectly called into question – in particular:
- “Fat makes you fat”
- “Whole grains are always healthy and the basis of nutrition”
- “Carbohydrates are unproblematic as long as little fat is consumed”
- “Light products are the better choice”
- “Animal products should be avoided as far as possible”
Such paradigms sometimes persisted for decades and shaped not only households, but also education systems, politics, medicine and the food industry.

Why does it take so long for nutritional knowledge to change?
Nutrition is not only biology – it is culture. Changes to guidelines and habits take time, because:
- habits run deep Nutrition is routine. Change means effort and uncertainty.
- people are reluctant to leave comfort zones New knowledge demands new behaviour – and this meets resistance.
- economic interests are involved The food industry is a massive market with strong lobbies.
- societal establishment takes decades From research to broad acceptance, 20–40 years often pass.
Professionals too – doctors, trainers, nutritional advisors – often adapt their knowledge only with a delay. That is human, but relevant.
Will Europe and Switzerland follow?
An exciting question is: will Europe follow suit?
At present, the European guidelines – including the Swiss ones – appear markedly more conservative. They continue to emphasise:
- a higher carbohydrate share
- a stronger orientation towards grains
- caution regarding saturated fatty acids
- scepticism towards protein-rich forms of nutrition
Historically, Europe reacts more slowly than the USA in nutritional matters – partly out of caution, partly out of institutional inertia. An alignment could therefore take years to decades.
Points that, despite the progress, could be examined more closely
Despite the numerous advances, the new dietary recommendations are not free of open questions. Two points that could, among others, continue to be discussed are:
- Saturated fats The recommended upper limit for saturated fatty acids remains at around 10 % of daily energy intake. This appears remarkable insofar as, in parallel, the consumption of full-fat dairy products as well as of protein-rich foods such as meat and fish is emphasised – that is, foods that also naturally contain saturated fatty acids. The combination of a low upper limit and a protein-/fat-focused way of eating appears inconsistent at first glance and is therefore likely to remain a subject of scientific discussion.
- Carbohydrates and sugar Although a reduction of carbohydrates and whole-grain products is recommended and the graphic representation of the pyramid supports this trend, at the same time 2–4 portions of whole grains per day are stated – which in total still means a relevant amount of carbohydrates. The same applies to the sugar recommendation: a maximum of 10 g of added sugar per meal is, in the context of 3–4 meals per day, still relatively high, especially since many foods naturally contain sugar anyway. It is possible that a gradual transition is being sought here, so as not to overtax societal acceptance.
- Salt and electrolyte recommendations The recommendations on salt and electrolytes appear fundamentally progressive and for the first time also take physical activity into account. At the same time, the question arises whether the stated amounts are sufficient for very active people and those who do sports, or whether they would need to be further individualised.
- Fat quality and vegetable oils While animal fats and fat-rich protein sources are clearly named, it remains open how various vegetable oils should be handled. Here, indications on quality, processing, susceptibility to oxidation or on the ratio of omega-3 to omega-6 are missing, which would be relevant for practical implementation.
- Practical implementation & timing The recommendations define amounts and energy shares, but leave other practically relevant dimensions open – such as meal frequency, timing, fasting windows, seasonal or regional differences as well as the possible benefits of longer eating breaks. These topics are indeed increasingly being investigated scientifically, but so far find little place in the recommendations.
- Individualisation Finally, the fundamental question arises of how strongly nutrition should be personalised in future. Genetic differences, metabolic variants, activity level as well as intolerances and allergies argue that there may be no “one right diet for everyone” – not only worldwide, but also within a population.
Practical significance – also for trainers and everyday life
The core message can be formulated surprisingly simply:
More real foods, more protein, more healthy fats – less sugar, less industry, less empty starch.
It is interesting that these guidelines have long been reality in areas where trainers and coaches have already been working for a long time – for example:
- satiety through protein
- carbohydrate periodisation
- doing without Ultra-Processed Foods
- individualisation according to activity level

Conclusion: a step in a new direction
With their new dietary recommendations, the USA place a strong emphasis on:
- metabolic health
- prevention instead of therapy
- real foods instead of industrial products
- protein & fat instead of sugar & starch
Whether and when Europe and Switzerland will follow suit remains open. Historically, it would not be the first time that major nutritional impulses from the USA find their way to Europe – usually with a time delay and, depending on the context, with different consequences.
