In this episode of the Nutritionista Podcast, we dive into how caffeine impacts your gut, hormones, and overall energy levels. From its effect on digestion to the ways it influences blood sugar, hunger hormones, and even your microbiome, we unpack the full impact of that morning cup of coffee.

We also discuss the pitfalls of drinking coffee on an empty stomach, why different types of milk in your coffee could affect your digestion, and how caffeine affects your body's ability to regulate blood sugar, insulin, and hunger hormones like leptin and ghrelin. This episode is a must-listen for anyone looking to understand how their coffee habit might be influencing their health in ways they didn't realise.

Key Topics Discussed:

1. How Caffeine Affects Blood Sugar and Insulin:
   • We explore how caffeine reduces insulin sensitivity, leading to elevated blood sugar levels and midday crashes.
2. Caffeine on an Empty Stomach:
   • Drinking coffee without food can increase stomach acid, causing digestive issues like heartburn and gastritis.
3. The Role of Milk and Milk Alternatives in Coffee:
   • Not all milk alternatives are created equal. Learn how almond, oat, and nut milks can impact your blood sugar and digestion.
4. Hunger Hormones: Leptin and Ghrelin:
   • We break down how caffeine disrupts the balance of these hunger hormones, leading to increased cravings and overeating.
5. Caffeine and the Gut Microbiome:
   • Caffeine can stimulate gut motility and affect the diversity of gut bacteria, for better or worse.
6. Liver Detoxification:
   • Caffeine impacts liver detox pathways, and how this can influence hormonal balance, particularly oestrogen.

Next Episode Teaser: In Part 2, we’ll discuss how to time your caffeine intake, who should avoid it, and when it might be time to take a break. We’ll also dive into the genetic factors that influence how your body metabolizes caffeine.
