〰️ YOUR BRAIN + BLOOD SUGAR 〰️
you may have read that researchers are now calling Alzheimer’s disease “type 3 diabetes.” your brain is the most metabolically active organ in your body. it uses about 20% of your total energy, even though it’s only 2% of your body weight. and what does it run on? glucose. but it needs a steady supply, not a roller coaster.
when we eat in a way that sends our blood sugar spiking and crashing throughout the day, we’re starving our brain during those crashes. those moments of brain fog, difficulty focusing, forgetting why you walked into a room … they’re often directly related to blood sugar instability
cognitive decline isn’t something that suddenly happens in your 70s. it’s a gradual process that can start decades earlier. which means the choices you’re making right now, today, matter for your brain health 20, 30, 40 years from now
your brain has remarkable capacity for healing and regeneration when given the right support. neuroplasticity (your brain’s ability to form new connections) doesn’t stop at a certain age. it continues throughout your life.
here are some foundational strategies you can start today:
〰️ balance your blood sugar: never eat carbs alone. always pair them with protein, fat, or fiber
〰️ move your body regularly: exercise increases BDNF (brain-derived neurotrophic factor), which is like fertilizer for your brain
〰️ add colorful, antioxidant-rich foods: berries, leafy greens, foods rich in omega-3s. your brain is particularly vulnerable to oxidative stress
〰️ learn something new and challenging!
〰️ prioritize quality sleep: during sleep, your brain’s glymphatic system clears out metabolic waste products (including proteins that can contribute to cognitive decline)
