Food as Medicine: How Changing Your Diet Can Help Reverse Type 2 Diabetes and Prediabetes

What if the most powerful tool for transforming your health isn’t found in a pill, an injection, or a doctor’s surgery—but is actually right on your plate? Every bite you take, every meal you enjoy, has the power to support your body’s healing, boost your energy, and even help reverse chronic conditions like type 2 diabetes and prediabetes. It sounds almost too simple, doesn’t it? But the truth is, food is one of the most effective forms of medicine we have.

For decades, we’ve been taught to see food as just “fuel”—a numbers game of calories in, calories out. But food is so much more than that. Every time you eat, you’re sending powerful messages to your body and your brain. You’re telling it how to function, how to heal, and how to thrive.

The best part? You don’t need to follow extreme diets or complicated meal plans to see results. Small, thoughtful changes to your daily eating habits can have a profound impact on your health. In this article, I’ll show you how food can become your greatest tool for reversing type 2 diabetes and prediabetes. We’ll explore the foods that support your body’s natural ability to heal, the science behind why they work, and practical, sustainable steps you can start today.

Food is Information: What Are You Telling Your Body?

Let’s start with a simple but powerful idea: food is information. Every bite you take is packed with nutrients, vitamins, and minerals, all of which your body uses to perform vital functions. But not all foods send the same messages.

• Whole, unprocessed foods—like vegetables, nuts, seeds, and lean proteins—help your body thrive. They reduce inflammation, stabilise blood sugar, and support your cells to function at their best.
• Processed, sugary, or nutrient-poor foods do the opposite. They increase inflammation, spike blood sugar, and make it harder for your body to function well.

For people with type 2 diabetes or prediabetes, this connection is especially important. When you eat carbohydrates, your body breaks them down into glucose, which enters your bloodstream. Too many refined carbs (like white bread, pasta, or sugary snacks) can cause blood sugar spikes. Over time, these spikes lead to insulin resistance—the root cause of type 2 diabetes.

In contrast, foods rich in protein and healthy fats have a much smaller impact on blood sugar. They help you feel full, keep your energy steady, and support your body’s natural balance. That’s why I often recommend a low-carb or therapeutic carbohydrate restriction approach: by reducing sugar and refined carbs, you give your body a chance to heal.

The Power of Small Changes

You don’t have to be perfect or overhaul your entire diet overnight. Even small changes—like swapping white rice for cauliflower rice, or choosing water over sugary drinks—can make a huge difference. The key is consistency and a willingness to experiment with what works best for you.

The Science: How Food Can Heal Your Body

There’s a growing body of research showing that food can act as medicine, especially for conditions like type 2 diabetes and prediabetes. Here’s how:

1. Reducing Inflammation

Chronic inflammation is a major driver of diabetes and many other health conditions. Certain foods act as natural anti-inflammatories, calming your body’s immune response and creating the right environment for healing. These include:

• Leafy green vegetables (spinach, kale, chard)
• Fatty fish (salmon, mackerel, sardines)
• Spices like turmeric and ginger
• Extra-virgin olive oil
• Berries (blueberries, raspberries)

2. Stabilising Blood Sugar

The foods you eat have a direct impact on your blood sugar levels. Low-glycaemic foods—like non-starchy vegetables, nuts, and seeds—release sugar slowly into your bloodstream, preventing spikes and crashes. This helps your body maintain steady energy and reduces the strain on your pancreas.

• Non-starchy vegetables: Broccoli, cauliflower, peppers, courgette, aubergine
• Nuts and seeds: Almonds, walnuts, chia seeds, flaxseeds
• Whole foods: Eggs, poultry, oily fish, tofu

3. Nourishing Your Cells

Your body is made up of trillions of cells, and every single one relies on nutrients from your food to function. When you eat a diet full of vitamins, minerals, and antioxidants, you give your cells the tools they need to repair and perform at their best. Sadly, most processed foods are lacking in these vital nutrients.

Why Modern Diets Are Failing Us

Let’s take a step back and look at the bigger picture. Imagine living thousands of years ago—no supermarkets, no processed snacks, just the food nature provides. Our bodies evolved to thrive on real, whole foods: vegetables from the earth, fruits from trees, and animals that grazed on grass.

Fast forward to today, and the food industry has outpaced our evolution by centuries. Factory-made foods are cheap, convenient, and addictive—but the damage they cause is slow and subtle. Unlike an allergy, where the reaction is immediate, the harm from processed foods builds up over years and decades.

The Slow Burn of Processed Foods

Think about it: if someone with a peanut allergy eats a peanut, the reaction is immediate and life-threatening. But when we eat highly processed foods—crisps, biscuits, ready meals—the damage is slow. We don’t see the harm right away, so we keep eating them, often without realising the impact on our long-term health.

Common Mistakes: Don’t Fall for “Healthy” Processed Foods

Many people with type 2 diabetes or prediabetes look for low-sugar biscuits, low-carb bread, or artificial sweeteners so they can keep eating the same way. While these products may help with short-term blood sugar control, they often contain chemicals and additives your body isn’t designed to process. Instead of healing, these foods can actually fuel inflammation and insulin resistance.

Ask yourself:
Are you really doing your body a favour, or are you just funding food companies to make even more processed products with ingredients our bodies can’t recognise?

Going Back to Basics: What Should You Eat?

So, what’s the answer? It’s about going back to basics. Ask yourself: what would my ancestors have eaten? Even just a few generations ago, food was simpler and less processed.

Foods to Focus On:

• Fresh vegetables and fruits: Especially non-starchy veggies and low-sugar fruits like berries
• Nuts and seeds: Great for snacking and adding crunch to salads
• Meat and fish: Choose animals raised naturally, if possible
• Eggs: Packed with protein and nutrients
• Healthy fats: Olive oil, avocado, nuts, oily fish

Foods to Limit or Avoid:

• Factory-made biscuits, crisps, and ready meals—even if labelled “low sugar” or “low carb”
• Sugary drinks, juices, and energy drinks
• Highly processed breads, cereals, and snack bars
• Artificial sweeteners and “diet” foods

Practical Tips: Making Changes That Last

Changing your diet doesn’t have to be overwhelming. Here are some practical steps you can take:

1. Start Small

Pick one meal a day to improve. Swap your usual breakfast for eggs and spinach, or add a handful of greens to your lunch.

2. Plan Ahead

Meal planning helps you avoid last-minute choices that might not serve your health goals. Try batch cooking or prepping veggies in advance.

3. Read Labels

Look for foods with short ingredient lists and avoid products with ingredients you can’t pronounce.

4. Stay Hydrated

Water is your best friend. Swap sugary drinks for water or herbal teas.

5. Celebrate Progress

Focus on the positive changes you’re making, not perfection. Every step counts!

Final Thoughts: Trust Your Body’s Design

Your body is extraordinary. It’s been shaped over thousands of years to thrive on real food—not ultra-processed products. Every time you choose whole foods, you’re giving your body the tools it needs to heal and flourish. It’s not about perfection or deprivation; it’s about making small, intentional choices that lead to life-changing results.

When you align your diet with what your body was truly made for, you’re not just eating—you’re using food as medicine.
