I'd certainly do that before taking any possibly nasty medication..
Can coffee with a drop of semi skimmed milk affect a blood test? My HBA1c had jumped big time last week and my triglycerides were also high again going from 6.7 to 7.3 since last July (even on these nasty pills!) although bizarrely my cholesterol had dropped from 5.6 to 5.0 since last time. I might also have eaten late as well the night before although I can't remember. When I got to the surgery she said she wasn't aware that I was down for my HBA1c test (which they don't ask you to fast for now) but she said she would do a general bloods instead which I am sure you do have to. Therefore wondering if that coffee and possible late eating made a difference? Also a tad worried now that to get the HBA1c down I am cutting right back on carbs and eating more fat but will that increase my cholesterol even more?
"they" never have.. cholesterol testing is fasted not HbA1c. Full lipid panel shouldbe anyway.
Coffee has been know to have an impact on triglyceride levels which is why water fasting for 12-14 hours before the blood is taken should always be recommended.
In short no.
An HbA1c test represents an average blood glucose over the past 12 weeks, it is not affected by recent meals and does not require fasting.
Many thanks gents.
Just adding this paper on lipid panels and the ketogenic diet. Currently listening to one of the authors - Dr Nick Norwitz - on Clubhouse!
Coffee made in cafetieres or by passing water directly through ground beans can raise cholesterol quite considerably. I only found this out recently. Filtering coffee removes the oils responsible.
An interesting study indeed, but sadly an (n=1) study so cannot infer a generalised message. The subject is also not available for follow-up (seemingly) so long-term efficacy cannot be established either. But the science in the study seems sound and is supported by other researchers. It is the fluffy big ones that are the friendly ones, and the small dense ones the peaky blinders,
Good to know, thank you. I nearly always use a filter rather than a cafetière.
In the back of my mind I knew there was a good reason for this but couldn’t remember what!
In the short term I guess?
Cholesterol levels can after all be pretty dynamic.
I'm guessing in the short term as well. The research came after a discussion with a friend who has had cardiovascular issues and was prescribed statins amongst other drugs. He virtually became a different man as a result - could only walk 100m before the pain became agonising etc.
He also drank 6-8 cups of coffee a day but discovered that his blood cholesterol levels dropped considerably when he stopped drinking coffee. Hence the research and at the moment I can't find the relevant papers. I have retained a clip from a doctor's column in a women's magazine that also says not to drink unfiltered coffee before a lipid panel as it can raise the outcome by as much as 10%.
But depending on his lipid panel that might not have been a good thing..?
I too have read that for some people coffee can impact cholesterol tests but not all.
One example here
He had very high LDL which is why he was prescribed statins in the first place. I don't know about his ratios. I just know that without the statins he has returned to his old, lovable self!
And again LDL is not necessarily the "bad" character it is made out to be..
Statins do appear to be the devil though.
Definitely another for the library..
Interesting and short glimpse at cholesterol and why more isn't "bad".
statins work by disrupting the Mevalonate pathway. They not only stop you producing cholesterol they stop you producing Thyroid hormones, sex hormones, CoQ10, D3 and Selenium.
please may I have some links to where you found this information?
reduce carbs not saturated fats, saturated fats do not cause your insulin levels. If you reduce dietary fats your liver just makes more cholesterol. Every cell .com your body is lined with cholesterol. The brain makes its own because it is essential for repair and replacement of the neurons and synapses, without this you develop dementia. Almost 50% of the brain is made up of cholesterol.
hi it is in Dr Malcolm Kendrick's book The Great Cholesterol Con, I'm sure he also talks about it on YouTube too. There are lots of examples in Google, look up HMG-coA Reductase and Mevalonate pathway.
