Abigail's notes

Coffee. Mother nature's greatest gift to humanity.

I dream about my morning coffee the night before. I have been this way for years. I was a barista for about eight years and if I could make a true living off of it I genuinely think I might go back. There is something about that world that gets into you.

The global warming situation with coffee crops is something that legitimately breaks my heart for more reasons than one. The specific atmospheric and environmental conditions that allow coffee to thrive are increasingly under threat, and as someone who considers coffee a non-negotiable part of daily existence this is deeply personal. I also consider people's right to live and farm and exist in reasonable conditions is personal... okay back to the plant.

Coffee is a diuretic and stimulant, which explains the famous large cold brew effect. You know the one. It gets the digestive juices moving in a very prompt and efficient manner. It can also paradoxically help with headaches despite being a common headache trigger at high doses, because caffeine constricts blood vessels and that's actually part of how some headache medications work.

A note on quality: how coffee is roasted and stored matters more than most people realize. Poorly stored beans can develop mold, which you absolutely do not want to be ingesting daily. Whole beans lessen that risk compared to pre-ground. And if you're in the US, worth knowing that American markets have historically received lower quality beans compared to European markets due to weaker regulatory standards. A fun fact that will ruin grocery store coffee for you forever. Sorry.

Safety note: Caffeine is genuinely addictive. Stopping regular intake can cause headaches for around four days, which is your body's very pointed way of telling you it has developed a dependency. Excessive intake can cause heart palpitations, poor sleep, and anxiety. Everything in moderation, except I don't fully practice what I preach here and I'm at peace with that.

Know your sources.
Magnifying glass over a web browser window, symbolizing source verification or fact checking.

Check the source, not just the headline

Who wrote it? What are their credentials? Who published it and why? A wellness blog and a peer-reviewed journal are not the same thing, even when they say the same words. Always click through to the original source.

Check the date

Science updates over time. A 2003 study on a supplement may have been contradicted twelve times since. Always look for the publication date and whether newer research exists. "Studies show" means nothing without a timestamp.

Follow the money

Who funded the study? A supplement company funding research on their own supplement is a conflict of interest. It's not automaticly a disqualification, but worth noting. Look for the "funding" or "disclosures" section of any study you read.

Understand study types

Not all research is equal. A randomized controlled trial carries more weight than a case study or an animal study. "A study found..." could mean ten people in a lab or a decade-long population study. The difference matters enormously.

Cross-reference everything

If only one source is saying something, be skeptical. If ten independent sources across different institutions, different countries, different decades are saying the same thing, you're getting warmer. Consensus is earned, not declared. Studies should be peer reviewed.

Use the NIH and examine.com

The National Institutes of Health database (PubMed) is free and searchable. Examine.com aggregates supplement research without selling anything. Both are significantly more reliable than any wellness influencer, including me.
