11.4: todo.health/probiotics/is onion a health food?:
. onion is a glycemic food 
but has se-msc, the favored form of selenium;
and unlike garlic, it doesn't make you smell bad .
. npr radio was talking about microbiome profiles,
and they said good food for the probiotics (the beneficial bacteria)
includes garlic, onion, and leeks .

. however, this source also recommended
whole grains, which disagreed with other experts;
on the other hand, grains are very popular
so he was likely just saying high fiber is good,
without actually giving grains the ok .
se-Methylselenocysteine (se-MSC):
Selenium anticancer research of the past 15 years
has focused heavily on a novel form of selenium:
A relatively simple organic selenium compound,
se-MSC is formed naturally in various plants,
including garlic, wild leeks, onions and broccoli
when grown on high selenium soil. [Whanger 2002]
onion provides more se-msc:
Usually, nonaccumulating plants such as Arabidopsis
and Secondary accumulating plants
such as Indian mustard (Brassica juncea)
store Se mainly as selenate
when the plants are fed with selenate.
In contrast,
selenate-supplied biofortified vegetables,
such as garlic (Allium sativum), onion (Allium cepa),
leek (Allium ampeloprasum)
and broccoli (Brassica oleracea),
store Se predominantly as SeMeCys [se-msc] .
