Ok, here's the deal.
1. Cholesterol intake per se tends to have a minor effect on total blood
cholesterol. first and foremost, your liver makes more cholesterol on a
daily basis (anywhere from 1.5-2 grams/day) than you would generally eat
(well, 2 grams per day of cholesterol would be 7 whole eggs). On top of
that, liver cholesterol production adapts to your intake. So when you
eat more cholesterol, the liver typipocally downgrades its own
cholesterol production ; when you eat less cholesterol, the liver
upregulates its own cholesterol. This is all basic physiology, in any
decent textbook.
1a. However, there is a wide range of difference in how people respond
to dietary cholesterol per se. There are both hypo and hyperresponders
meaning that some people are sensitive (in terms of total cholesterol
levels) to dietary cholesterol intake. But certainly not all.
2. The bigger issue in blood cholesterol intake has to do with fatty
acid intake NOT cholesterol intake. For example, most saturated acids
tend to raise blood cholesterol levels by affecting liver metabolism
(differently than dietary cholesterol intake does). There are
exceptions, such as stearic acid which is saturated but doesn't affect
blood cholesterol intake. Monounsaturated fats (olive oil, which is
oleic acid, being the primary one) has a neutral effect on blood
cholesterol levels. Polyunsaturated fats (w-6 and w-3) have cholesterol
lowering effects, in general.
3. Now, *in general* foods high in cholesterol are also high in
saturated fats but this is not always the case. Even lowfat foods such
as chicken and lowfat fish contain cholesterol because it is part of the
cell membrane. Eggs contain both cholesterol and saturated fat
(although there are more polyunsaturated fats in eggs than most people
realize, you can check the USDA database to check that). Same with
fatty cuts of red meat: both cholesterol and saturated fats are present
(note that red mea
Actually, dietary cholesterol has little to no impact on serum
cholesterol. When you consider that the average intake of dietary
cholesterol is maybe 300-500 mg for most people and the body normally
manufactures about 2 grams per day of the stuff, there's no way that what
you're eating cholesterol wise could have any impact. Now, saturated
fats, there's another situation. Without getting into the major biochem
of it, saturated fats have been shown to increase serum cholesterol, at
least in a mixed diet condition. I've seen no studies looking at
saturated fat intake while on a ketogenic diet but, anecdotally, many
people report an improvement in blood lipid profile (meaning LDL goes down
and HDL goes up). Also, what mainstream dieticians don't tell you is
that:
1. Extremely
high carb diets have been shown to elevate triglycerides and
hyperinsulinemia seems to have some impact on atherosclerosis
2. Extrememly low fat diets have been shown to increase all cause death
rates as much as high fat diets. Can you say moderation boys and girls?
The media wants a single-bullet theory of cholesterol: Fat is bad.
Cholesterol is bad. Fat isn't bad but saturated fats are bad. Trans fatty
acids might be bad. **** that.
There are some case studies of people who have eaten tons and tons of eggs
per day with no change in serum cholesterol levels at all so the genetic
component can't be discounted either.

Wait, that's not how statistics work?
Now I'm confused.
Case in point, I saw on tv (so it must be true) that folks who drink
alcohol are like 7X more likely to engage in sex.
So I tried sitting at home drinking, but I still didn't get laid.
Wha' happened?
Co do wnioskow powiazania Dezira z dieta lowcarb i tak duzym spozyciem jajek - tych o aktywnosci, genetycznym niskim poziomem itp oraz spozyciem zfdrowych tluszczy jednonienasyconych itp - zgodze sie - sa sluszne - ale dla mnie to podstawa (aktywnosc fizyczna i spozycie zdrowych tluszczy) - po cholere zabierac sie za tego typu diety jesli nie ma sie pojecia o spozyciu zdrowych nnkt oraz aktywnosci fizycznej
taka mala dygresja
milej lektury !
pozdrawiam
Jak jesz - tak zyjesz
Wiedza to podstawa
