I'll add this speculation (take with a grain of salt, but it makes hypothetical sense): https://www.msn.com/en-us/health/wellness/chronobiologist-and-nobel-laureate-in-medicine-michael-rosbash-lack-of-sunlight-during-the-day-is-worse-than-electric-lighting-at-night/ar-AA1kS5y3 https://www.msn.com/en-us/health/wellness/chronobiologist-an... from: https://news.ycombinator.com/item?id=38513782 https://news.ycombinator.com/item?id=38513782 : One hypothesis has to do with our DNA damage repair systems, which are regulated by the circadian clock. Food contains a mixture of nutrients and toxins. Plants produce toxins to avoid being eaten, such as psoralen, which is abundant in celery. Snacking at night introduces toxins that, at that hour, our repair systems are not ready to eliminate. There is also speculation that the major epidemic of epithelial cancers, such as colon cancer, in the U.S. is because of this. Basically plants may be good in general, but become problematic to long-term health if, like anything else, eaten close to bedtime. Edit: For god's sake downvoters, read what I wrote and THINK ABOUT IT before downvoting. I AM A VEGETARIAN, AND LIKE EATING VEGAN. I'm just warning people that VEG EATING LATE AT NIGHT comes with it's own RISK FACTORS. So YES, PLEASE DO CONSIDER A VEGAN DIET, BUT ALSO EAT HEALTHY BY NOT EATING CLOSE TO BEDTIME OR NIGHT SNACKING!!! OTHERWISE YOU MAY INCREASE YOUR CANCER RISK FROM EATING CERTAIN VEGETABLES CLOSE TO BEDTIME!!!!!!
