The older I get, the more I get interested in nutrition and health. In the last couple of years I’ve read almost 10 books about nutrition, human biology and physiology, the history of food, mental health, etc.
When you take everything in, a few of things become immediately obvious:
- We are liteally killing ourselves. Rates of chronic conditions like heart disease, asthma, cancer, and diabetes have grown 700% since 1935.
- Although a more sedentary lifestyle, pollution and high-levels of stress all play a role, the most likely culprit (as believed by the majority of scientists and where most of the evidence points to) is our diet; the rates of chronic diseases matches perfectly the increase in consumption of vegetable oils, sugar and processed food. Jeff Nobbs has written an extensive article about why vegetable oils are so bad for you. If you want to learn more about sugar and the diabetes pandemic, read the excellent “The case against sugar“.
- The way we produce food is broken, both in the sense that it destroys the environment and that the food produced is low quality.
- The massive increase of pesticides and herbicides in agriculture has started to show its nefarious consequences. Glyphosate, the active ingredient in the herbicide RoundUp (unsuprinsingly produced by Monsanto), has proven links with hormone disruption, increased cancer rates, infertility, gut issues and more.
- Our unbalanced diets wreak havoc on our bodies and are also linked to all sorts of neurological problems, like dementia, violent behaviour, addiction, etc. Justin Mares has recently written about several studies conducted in the UK and US about the role of Omega-3 in violent behaviour. The short version? A diet poor in omega-3 fatty acids increases aggression, depression and compulsive behaviour.
What’s the solution?
I’m afraid finding a solution is way above my paygrade but to me the best thing we can do, individually, to change things is to be more aware of what we put inside our bodies.
Eat real food. Buy whole ingredients and cook at home. The more natural, whole, close to nature the food, the better. If you haven’t already, do yourself a favour and buy “Food Rules“ by Michael Pollan.
Too many people waste time debating the type of diet one should follow (vegetarian, vegan, etc) but miss the most important point: unless your food is of the highest quality, your principles don’t matter.
Eat local. Know your farmers and the land where your food is grown. The reason so much of our food is unhealthy is the perverse incentives of modern agriculture and mass-production. By supporting local farmers you put money into their pockets and incentivise local production.
End of rant.

Over the past century, technological advancements have massively reduced the cost and time needed to create and circulate content. Though this has liberated artists, consumers are now drowning in a virtually infinite supply of things to watch, listen to and read. The answer to a world where attention is the key constraint it’s the Influencer Curator. If you read only one article this week, make it this one.
How do you explain, from a biological perspective, that we are a miserably violent species, capable of genocides and mass rape as a weapon, yet also an extraordinarily altruistic, compassionate one?
You can only be an optimist in the long run if you’re pessimistic enough to survive the short run. The best way for most people to apply that is: save like a pessimist, invest like an optimist.
Here’s a great list of some rules of thumb about the world. Some of my favourites: “The person who tells the most compelling story wins. Not the best idea.“, “Almost everything has been done before. The characters and scenes change, but the behaviors and outcomes rarely do.“ and “Don’t expect balance from very talented people. People who are exceptionally good at one thing tend to be exceptionally bad at another.“
That the a small elite of ultra-rich controls the power in the US is overused cliché. But why money and not other interests, like a religious group or the military? To answer this question you need to study the history of the US and how different groups of power came to be.
Network effects account for 70% of all the value created in technology since 1994, since many winner-take-all-companies in tech were powered by them. This post summarises everything you need to know about network effects.
