BRAIN REPAIR

The brain has its own waste removal system which is similar to the bodies lymphatic system called the Glymphatic system.


When we fall into a deep sleep, the hippocampus part of the brain will shrink by 200%. This leaves room for cerebral spinal fluid to wash beta-amyloid and other metabolic waste out of the brain.


This happens during the deep non rem sleep cycle which is the early stage of sleeping. It’s important not to wake up or disrupt this process as it will affect how much fluid is released into the brain cavity.


The Glymphatic system operates most efficiently when the body is horizontal. Falling asleep or dozing off upright will severely limit the release of spinal fluid.


For optimal results sleeping on your side with legs slightly raised will increase the Glymphatic wash process.


Zone 2 training, where you are training at a low-level heart rate (being able to talk but not sing) has also been shown to support the Glymphatic system.


This can be done on a stationary bike or cross-trainer for 45mins to an hour, 3 times per week.


You will also get the added benefit of making your mitochondria more efficient in utilising fat oxidisation for energy.


Each night if you are not getting enough sleep the waste product (beta-amyloid) accumulates, leading over time the risk of Alzheimer’s Disease.

Roast the carrots and mushrooms Preheat the oven to 200°C (400°F) . Line a baking tray with parchment paper. Toss carrots with olive oil, salt, pepper, and honey/maple syrup if using. Spread on half of the tray. Place the portobello mushrooms on the other half, drizzle with olive oil and balsamic (if using), and season with salt and pepper. Roast for 25–30 minutes , turning once halfway through. Mushrooms should be tender and juicy; carrots caramelized and golden. 2.

Grill for 2–3 minutes per side , or until cooked to your liking (medium-rare to medium recommended). Rest for a few minutes before serving to keep tender and juicy. 3. Steam and fry the broccolini Bring a small pot of water to a boil, and lightly steam broccolini for 2–3 minutes until bright green. Drain well. Heat butter and olive oil in a frying pan over medium-high heat . Add the broccolini and sauté for 2–3 minutes , seasoning with salt and pepper until slightly crisp on the edges. 4. Serve Plate each portion with a serving of grilled beef strips, a whole roasted mushroom, a few roasted carrots, and a generous side of buttery broccolini. Drizzle any beef or mushroom juices over the top for extra flavor. Optional Garnish Sprinkle with fresh parsley or thyme before serving. Add a squeeze of lemon over the broccolini for brightness.
