The biggest nutrition trends of 2026 and which are worth following?

Every year, the internet decides it's found the missing piece. This year it's fibre. Last year it was protein. Before that, fermented foods, collagen, and the list goes on. Some of it sticks. A lot of it doesn't.

Here's what's circulating so far in 2026, and an honest take on which trends are worth your attention.

Fibremaxxing

Yes, that's a real word now. Or at least, it's a real TikTok word.

The trend involves actively tracking and maximising fibre intake, and this trend is one I can get behind as it maps closely to the evidence. A whopping 96% of the UK population are not meeting the NHS 30g daily fibre recommended intake. Similarly, in America roughly 95% of the population are falling short of the recommended fibre intake.

Fibre is worth the attention it is getting because of the following reasons:

• Soluble fibres (e.g. oats) help to manage healthy cholesterol levels.
• Fibres form a gel-like substance in our gut that can help to slow down the absorption and digestion of carbohydrates. This may support a steady release of glucose into the bloodstream.
• Fibre also promotes healthy bowel movements by providing bulk to our stool.

Worth following? Yes. Slow and steady wins the race for fibre, so make sure you increase your intake gradually. Try to think of fibre like a sponge - it is important to stay hydrated whilst increasing fibre intake.

A great way to introduce yourself to more fibre is by swapping to wholegrains, adding seeds as toppings, or grab a Huel Lite Ready-to-drink for 6g of fibre in a bottle.

Gut health

It's been "the year of gut health" for a few years now. This is no bad thing, especially as this includes fibre.

The underlying science is genuinely interesting. The gut microbiome (the collection of bacteria, fungi, and other microorganisms living in your gastrointestinal tract) is an active area of research that is still ongoing. Diversity of fibre sources and fermented foods like kefir and yoghurt are topics that are more thoroughly researched, and are associated with a more varied microbiome.

Worth following? A diverse, balanced diet that includes a variety of plants is worth following.

Protein – still king

Protein isn't going anywhere, and protein remains at the top of the macronutrient pyramid. Protein is still one of the nutrients that matters most for anyone training seriously. The 2026 conversation isn't about eating less of it - it's about being smarter with it. The takehome message is distributing protein intake across meals whilst hitting your targets consistently.

Worth following? Keep your protein intake consistent with your goals.

The year of the bean

2026 has seen the boom of the bean. Quietly, without a rebrand or a celebrity endorsement, beans became interesting again. Chickpeas, lentils, black beans and edamame are having a moment that's actually earned. Butter beans in particular have gone from a tin at the back of the cupboard, to a restaurant menu staple. Beans are one of the few foods that tick multiple boxes at once: decent protein and significant fibre, and they hold great bulking power for many dishes.

Worth following? The flexibility of beans will always get my vote.

GLP-1 medications and the nutrition conversation around them

GLP-1s were the dominant story of 2024 and 2025. In 2026, the conversation is shifting from the drugs themselves to what people should be eating while taking them.

Because GLP-1 medications reduce appetite significantly, people on them often eat much less. That makes nutritional density more important. Getting adequate protein, fibre, omega-3s, vitamins, and minerals from a smaller volume of food is harder than it sounds.

Worth following? Whether you're taking GLP-1s or not, the underlying principle applies: nutrient density matters.

Personalised nutrition and CGM

Continuous glucose monitors (CGMs) are showing up on the arms of people without diabetes. CGMs appeal is real-time data on how your blood sugar responds to specific foods, which is a more personalised approach to eating than general dietary guidance. You may have seen these popping up on the upper arm of individuals For people managing diabetes, that data is undeniably beneficial. However, for individuals without diabetes, the evidence is lacking. Blood sugar rising after eating carbohydrates is normal physiology, not a red flag. The concern is that without that context, CGM data can nudge people toward unnecessary dietary restrictions.

Worth following? Due to limited evidence, the perceived benefits may owe more to effective marketing than robust science.

The honest summary

Most nutrition trends contain a grain of truth wrapped in a lot of noise. The useful habits such as eating enough fibre, distributing protein, prioritising nutrient-dense whole foods, aren't new. They're also not very exciting to post about. The things that consistently hold up don't change much year to year. The things that trend usually don't. Eat your beans, hit your fibre, and if you don’t have diabetes - don't let a sensor on your arm tell you bananas are off the menu.
