. milk is not considered to be paleo because of
lactose causing inflammation [sciencenews.org].
(and many other reasons)[Dr.Cordain];
would yogurt's fermentation convert all lactose?
no, per 6-ounce serving, there is
nearly 6.8 grams Greek yogurt
nearly 8.5 grams in whole-fat yogurt
and 14 grams in non-fat yogurt [sfgate.com];
-- Greek yogurt has the whey drained off .
. there is "100% grass-fed" yogurt
but it won't be zero lactose .
. if you ferment yogurt long enough,
it will convert most of the lactose,
especially if starting from cream instead of milk [paleoleap.com].
. the women who drank milk 3 glasses or more per day
were almost twice as likely to die
during the 20 year course of the study.
They also had a 16% higher risk of bone fractures
than those who drank less milk,
this wasn't seen in the people consuming yogurt or cheese.
The proposed mechanism was that the
breakdown products of lactose, galactose,
is causing an increase of inflammation [sciencenews.org].
. but yogurt does have lactose [sfgate.com];
so, what is even brief fermentation doing to it?
. whey protein isolate contains
1-3 grams of lactose per serving [iherb.com]
and, unlike yogurt and cheese,
whey isolates remove most of the casein
(whey isolate lowers cholesterol levels,
whereas, casein protein raises cholesterol)[lef.org].
. if casein raises the risk of cancer,
then Campbell's China Study didn't prove it
. if you have a gut infection (SIBO)
then you might also become histamine intolerant,
and yogurt could worsen that condition
because it is a histamine producing food
due to the types of germs it uses:
# Histamine degrading bacteria:
Bifidobacterium infantis (found in breast milk),
Bifidobacterium longum, Lactobacillus plantarum,
and some soil-based organisms.
# Neutral bacteria:
Streptococcus thermophiles (also in yogurt)
and Lactobacillus rhamnosus (shown to
down regulate histamine receptors
and up-regulate anti-inflammatory agents)
# Histamine producing bacteria:
Lactobacillus casei, Lactobacillus reuteri, and
(Found in most yogurts and fermented foods)
Histamine is an inflammatory mediator;
the immune system's first responder
Histamine intolerance is generally caused by
a defect in the body’s histamine breakdown process,
in one of two enzyme systems:
histamine N-methyl transferase (HMT)
and diamine oxidase (DAO).
. a primary cause of histamine intolerance
is an overgrowth of certain types of bacteria
that make histamine from undigested food,
leading to a buildup of histamine in the gut
and overwhelming the body's ability to
catabolize the excess histamine.
. Common symptoms of histamine intolerance include:
Tissue swelling (angioedema)
especially of facial and oral tissues and sometimes the throat,
the latter causing the feeling of “throat tightening”
Hypotension (drop in blood pressure)
Tachycardia (increased pulse rate, “heart racing”)
Symptoms resembling an anxiety or panic attack
Nasal congestion, runny nose, seasonal allergies
Conjunctivitis (irritated, watery, reddened eyes)
Fatigue, confusion, irritability [chriskresser.com].
