Coffee - Green Tea?

Excerpt from Paleo Fitness p.163

Coffee:

• pro-inflammatory (elevated cytokines in the blood as well as links to gut irritation);
• blocks absorption of micronutrients;
• promotes elevated cortisol secretion; 
• cross-reactivity for those who are gluten sensitive; 
• elevates heart rate;
• affects both deep and REM sleep by reducing quality by 25% with just 1 cup of coffee before 7am;
• and for many people it masks the reason you don't naturally feel energetic and exuberant in the morning without this effective pick-me-up.

Try green tea instead :-)
