At Kore, we spend a lot of time reading research, working with real patients, and separating what sounds good from what actually works.
Here’s the honest truth:
There is no need to reinvent the wheel.
Some of the best nutrition science in the world is already being done. One of our favorite research-driven companies in the gut health and nutrition space is ZOE. Their work is led by world-class scientists (including Prof. Tim Spector and Prof. Sarah Berry), and they run some of the largest nutrition and microbiome studies ever done.
Their advice is:
- Evidence-based
- Practical
- Sustainable
- And actually works in real humans
So instead of creating “another diet,” we often guide patients using these 8 simple, science-backed principles.
They’re not extreme.
They’re not trendy.
They’re just smart.
The 8 Nutrition Principles We Love (And Use at Kore)
1. Eat Mindfully (Because Digestion Starts Before You Take a Bite)
Most people think digestion starts in the stomach.
In reality, digestion starts in the brain.
Thinking about food, smelling food, seeing food, and preparing food all activate what’s called the cephalic phase of digestion. This is when your body starts releasing:
- Stomach acid
- Digestive enzymes
- Bile
- Pancreatic enzymes
These are the tools your body needs to break food down and absorb nutrients properly.
When we eat stressed, rushed, distracted, or on the go:
- We make fewer enzymes
- We absorb fewer nutrients
- We get more bloating, reflux, and indigestion
Mindful eating means:
- Slowing down
- Looking at your food
- Smelling your food
- Chewing well
- Letting your nervous system shift into “rest and digest” mode
At Kore, we see this improve digestion, bloating, and even nutrient deficiencies without changing the food itself.
You can eat the world’s healthiest diet, but if you don’t digest it well, you don’t absorb it well.
2. Aim for 30+ Different Plants Per Week
This isn’t about being vegan. It’s about feeding your microbiome.
Different plants = different fibers = different good gut bacteria.
Research shows people who eat 30 or more different plants per week have a much more diverse and resilient gut microbiome than those who eat fewer than 10.
And yes, herbs, spices, seeds, and even coffee count.
3. Reduce High-Risk Ultra-Processed Foods
Not all processed foods are equal.
The real problem foods are the ones:
- Engineered to be overeaten
- Packed with additives, sugar, and refined oils
- Low in nutrients and fiber
These drive inflammation, blood sugar swings, and weight gain.
The goal is not perfection.
The goal is crowding them out with real food.
4. Focus on Food Quality, Not Calories
Your body does not respond the same way to:
- 100 calories of soda
- 100 calories of nuts or vegetables
Calories don’t tell you:
- How full you’ll feel
- How your blood sugar will respond
- How your gut will react
- How inflammatory the food is
At Kore, we care far more about:
- Nutrient density
- Fiber
- Protein
- Food quality
…than calorie math.
5. Set a Simple Eating Window (And Let Your Gut Rest)
Fasting can be helpful for certain people, at certain times, and for specific goals.
But for most people, most of the time, the biggest win is simply creating a daily break from eating.
Start with a 12-Hour Overnight Fast
This is the easiest and most sustainable place to begin.
Examples:
- Finish dinner at 7:00 pm → eat again at 7:00 am
- Finish dinner at 6:30 pm → eat again at 6:30 am
This gives your body:
- Time to fully digest and clear the gut
- A break from constant insulin signaling
- Time to shift into repair and cleanup mode overnight
For many people, this alone improves:
- Bloating
- Reflux
- Energy
- Late-night snacking
If You Want to Go One Step Further: Try a 10-Hour Eating Window
Once a 12-hour fast feels easy, some people do great with a 10-hour eating window.
That looks like:
- Eat between 8:00 am and 6:00 pm
- Or eat between 9:00 am and 7:00 pm
Same total food.
Just less time spent eating.
ZOE’s large Time-Restricted Eating study showed this can improve:
- Energy
- Bloating
- Snacking habits
- Mood
- Metabolic health
This is not about skipping meals or being extreme.
Think of it as digestive sleep for your gut.
6. Eat the Rainbow
Color in food = polyphenols and phytonutrients.
These plant compounds:
- Feed your good gut bacteria
- Reduce inflammation
- Support brain and heart health
Darker and more bitter often means more powerful:
- Arugula
- Berries
- Dark chocolate
- Black coffee
7. Focus on Protein Quality
Protein is essential, but source matters.
We prefer:
- Fish and eggs
- Fermented dairy (Greek yogurt, kefir)
- Legumes, seeds, nuts, and whole grains
Ultra-processed protein bars and shakes often come with:
- Sweeteners
- Gums
- Additives
- Gut irritation
Real food first.
8. Eat Fermented Foods Regularly
Fermented foods like:
- Kefir
- Yogurt
- Kimchi
- Sauerkraut
- Certain cheeses
Have been shown to:
- Improve mood
- Reduce bloating
- Improve energy
- Support gut bacteria
Even 1-3 servings per day can make a real difference.
The Kore Philosophy on Nutrition: Simple, Sustainable, Science-Backed
We don’t believe in:
- Extreme diets
- Food fear
- Punishment eating
- Perfection
We do believe in:
- Gut health first
- Metabolic health
- Real food
- Sustainable habits
- Smart structure
ZOE’s principles align beautifully with how we already practice nutrition and medicine at Kore, because they’re rooted in real science and real human biology.
You don’t need a new diet.
You need a solid foundation.
