In this episode, we close the Dirty Dozen series with the big one: Inflammation and oxidative stress. Inflammation isn’t just in the background. It speeds up every core defect in type 2 diabetes. The good news? You can cool this fire with simple, daily steps.

Listen in as Richie and Amber break it down in plain language, tie it to the 12 core defects from Dr. Ralph DeFronzo’s work, and give you a clear plan.

What Is Inflammation?

• Acute Inflammation: short-term and helpful (like a swollen thumb after a hit or an infection). Your body heals and the swelling goes down.
• Chronic Inflammation: long-term, low-grade. This is the problem. It can build for years and push insulin resistance and high blood sugars.

Oxidative stress is like “cell rust.” Your body makes it every day (even just breathing), and your built-in defenses (antioxidants, enzymes, repair systems) keep it in check. When the balance breaks, damage builds.

How Inflammation Touches All 12 Defects

Inflammation and oxidative stress weave through every system:

• Muscle: fat buildup sparks inflammatory signals that block insulin.
• Liver: fat in the liver drives “new sugar” making at night → fasting highs.
• Fat tissue: overfilled fat cells leak inflammation and pull in macrophages (immune cells).
• Gut hormones (incretins): gut inflammation lowers GLP‑1 effect.
• Alpha cells: inflammation blunts glucose sensing → more glucagon → higher sugars.
• Beta cells: insulitis (inflamed islets) harms and lowers insulin-making cells.
• Brain: cytokines jam hunger/fullness signals (leptin, insulin) → more cravings.
• Kidneys: inflammation can raise SGLT2 activity → kidneys reabsorb more sugar.
• Amyloid toxicity: misfolded proteins + free fatty acids + ROS hurt islets.
• Microbiome: “leaky gut” lets toxins in → low-grade Inflammation.
• Mitochondria: stressed engines leak ROS → more oxidative stress.
• Net result: Inflammation fuels insulin resistance and beta cell loss across the board.

How Do I Know If I Have Low-Grade Inflammation?

• Common signs: tired, more belly fat, poor sleep, high stress.
• Risk check: waist-to-hip ratio (ranges differ for men and women).
• Labs to ask your clinician about:
  • C‑reactive protein (CRP): a general inflammation marker
  • Fasting insulin (not perfect, but can hint at early insulin issues)
  • Note: Research tests like IL‑6 and TNF‑α exist but aren’t standard at big labs.

Chronic Inflammation can start 10–15 years before diabetes is diagnosed.

Meds That Can Help (But Don’t Replace Lifestyle)

• Metformin: can lower CRP and TNF‑α (inflammation markers).
• GLP‑1 receptor agonists: reduce systemic Inflammation, often via weight loss.
• TZDs (pioglitazone/Actos): act on fat tissue to lower inflammatory signals.
• SGLT2 inhibitors: may reduce oxidative stress and help mitochondria.
• Statins: not diabetes drugs, but can lower inflammation and protect vessels.
• NSAIDs (like ibuprofen): can ease pain, but they’re a short-term band-aid and can cause gut bleeds. Not a long-term fix for chronic Inflammation.

Meds help. Lifestyle heals the source.

Your Anti-Inflammation Action Plan

1. Build a plant-rich plate

• Make plants the star; meat the side.
• Aim for 5–9 servings of fruits and veggies daily.
• Eat more fiber: beans, peas, lentils; whole grains (try quinoa, farro, steel-cut oats).
• Go for color: greens, reds, oranges, purples = antioxidants.

1. Add anti-Inflammation fats

• Omega‑3s: flax, chia, walnuts, hemp seeds; fatty fish; algae oil (look for USP/NSF third‑party tested; 250–500 mg EPA+DHA/day if supplementing).
• Olive oil over ultra-processed oils.

1. Focus on polyphenols and carotenoids

• Polyphenols: blueberries, apples, pears, plums, green tea, coffee, olives/olive oil, turmeric, herbs (cloves, oregano, rosemary).
• Carotenoids (vitamin A family): carrots, bell peppers, leafy greens, sweet potatoes.

1. Move your body most days

• Even short walks help lower Inflammation (IL‑6, TNF‑α) over time.
• Start where you are. Add 5–10 minutes after meals. Build from there.

1. Protect your sleep and lower stress

• Aim for a steady sleep schedule and a calm wind-down.
• Poor sleep spikes inflammation and blood sugar.
• Try simple stress tools: breathing, light stretching, short walks.

1. Aim for 5–10% weight loss if advised

• Even this small loss can reduce inflammatory markers and improve insulin sensitivity.
• Slow and steady. Modest calorie deficit + daily movement works.

Adiponectin: A Quiet Hero

• Adiponectin is a hormone made by fat cells. Higher levels help protect beta cells and improve insulin sensitivity.
• Levels are often lower in obesity and type 2 diabetes.
• How to raise it naturally:
  • Gentle, steady weight loss
  • Omega‑3s (flax, chia, walnuts, fatty fish, algae oil)
  • Polyphenols (berries, green tea, coffee, herbs, olive oil)
  • Carotenoids (carrots, bell peppers, leafy greens)

Foods To Put On Repeat

• Daily: leafy greens, berries, beans/lentils, oats/quinoa/farro, nuts/seeds (flax/chia/walnuts), olive oil, herbs/spices
• Often: colorful veggies (carrots, peppers, broccoli), apples/pears/plums, green tea or coffee (if tolerated)
• Sometimes: fatty fish or algae oil (for omega‑3s)
• Limit: ultra-processed foods with long ingredient lists and added sugars

Simple Weekly Targets

• Plants: 5–9 cups fruits/veggies/day
• Fiber: 30+ grams/day (work up slowly)
• Movement: 150 minutes/week (or start with 10 minutes after meals)
• Sleep: 7–9 hours, consistent schedule
• Weight: aim for slow loss if needed (5–10% over time)

Glossary (Plain Words)

• Inflammation: your body’s “fire alarm.” Short-term helps. Long-term harms.
• Oxidative stress (ROS): “cell rust.” Your body can clean it up unless it builds too high.
• Cytokines (like IL‑6, TNF‑α): tiny signals that can raise Inflammation.
• CRP: a blood test that can show Inflammation.
• Insulitis: inflamed insulin-making cells in the pancreas.
• SGLT2: a kidney “sugar re-uptake” pathway.
• Adiponectin: a fat-cell hormone that protects beta cells and helps insulin work better.

Key Takeaways

• Inflammation and oxidative stress are not side stories. They drive type 2 diabetes at every step.
• You can lower Inflammation with what you eat, how you move, and how you sleep.
• Meds help, but lifestyle changes target the source.
• Even 5–10% weight loss can shift your body back toward health.
• You are not stuck. Small daily steps work.
