Green beans, red kidney beans, and white kidney beans - contain naturally a toxin known as phytohaemagglutinin. Food poisoning caused by this toxin in raw and inadequately-cooked beans has a short onset time (1-3 hours) with symptoms of nausea, vomiting and diarrhoea. However, this toxic substance can be destroyed by soaking and then cooking thoroughly at boiling temperature. Tinned beans which have been subjected to thorough heat-treatment are safe to eat without further cooking.

My refusing to eat flesh occasioned an inconveniency, and I was frequently chided for my singularity, but, with this lighter repast, I made the greater progress, for greater clearness of head and quicker comprehension. Flesh eating is unprovoked murder.

Carotenoids

Carotenoids are a class of more than 750 pigments synthesized by plants, algae, and photosynthetic bacteria. These richly colored molecules are the sources of the yellow, orange, and red colors of many plants. Fruit and vegetables provide most of the 40 to 50 carotenoid phytonutrients found in the human diet.

The most common carotenoids in North American diets are α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, and lycopene. 

Provitamin A carotenoids - α-carotene, β-carotene, and β-cryptoxanthin - can be converted by the body to retinol (vitamin A), but not lutein, zeaxanthin, and lycopene. 

Dietary lutein and zeaxanthin help maintain optimal visual function - they absorb damaging blue light that enters the eye.

The results of observational studies suggest that diets high in carotenoid-rich fruit and vegetables are associated with reduced risks of cardiovascular disease and some cancers. But high-dose β-carotene supplements did not
