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 .
web:
se-Methylselenocysteine (se-MSC):
Selenium anticancer research of the past 15 years
has focused heavily on a novel form of selenium:
se-MSC.
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] .
. whfoods` onion benefits,
vs leek benefits (careful with oxylates).

  1. 12.22: news.health/se/selenized onion:
    brage.bibsys.no:
    Sodium selenate was used as a source of Se.
    accumulation of Se is higher in broccoli than in onion.
    In broccoli, the highest accumulation of
    Se concentration was 44.28µg /g
    when treated with 80 mg Se
    and the accumulation of Se in onion
    was in the range of 6.11 to 8.31 µg /g
    treated with 50 mg Se.
    The net accumulation of Se lied within the safe limit
    and thus safe for the consumption for human.
    The accessibility is higher in onion than in broccoli.
