Mindsip insights from this episode:
Prepare gut environment with prebiotics for effective probiotics
Probiotics often fail because you can't simply add new bacteria to a gut environment that is not conducive to their survival; you must first change the environment with prebiotics like fiber.
Avoid pitfalls of keto diet to maintain healthy eating habits
The problem with the ketogenic diet is that it's very easy to fall off, and if you're not fastidious, you can end up on a worse diet that is high in fat and medium in carbs.
Protect liver from sugar and nourish gut with fiber
The core principle for health is to protect the liver from being overwhelmed by sugar and to feed the gut microbiome with fiber.
Understand NOVA classification to avoid chronic disease from ultra-processed foods
The NOVA classification system shows how a real food like an apple can become an ultra-processed food like an apple pie, which is the only stage associated with chronic disease.
Recognize veganism is not synonymous with health
A vegan diet is not inherently healthy, as proven by the fact that Coke, Doritos, and Oreos are all vegan.
Implement teaching breakfast model to promote healthy eating in families
A 'teaching breakfast' model for families proved successful by showing parents that their kids would eat the healthy food, they themselves would eat it, and they could afford it.
Feed your gut with fiber to boost serotonin and combat depression
When you starve your gut of fiber, the wrong bacteria can take over and suppress serotonin generation in the intestine, which is linked to depression.
