Higher blood pressure and blood sugar associated with poorer memory


Yet another study shows that by middle age people with elevated blood sugar levels and high blood pressure may already have significantly worse cognitive function:

UCSF: Early Cardiac Risks Linked to Worse Cognitive Function in Middle Age

As usual, this is about statistics, and correlation doesn’t prove causation. But the brain is sensitive – and it will likely be best off with a normal blood sugar and blood pressure.

If you want to keep your brain functions, you probably want to go easy on the Easter candy. And of course, it’s even more important how you eat on a daily basis.

How to Normalize Your Blood Sugar


  1. Howard Lee Harkness
    I've been on LCHF since 1999. I started with Atkins, moved to Protein Power, and have since moved more towards Paleo. I have pretty tight control of my blood sugar. Last time I checked, it was around 95, and my fasting level is usually around 90. Not as low as Jimmy Moore's, but way below anything considered diabetic.

    And I still have high blood pressure. It's still creeping up, and I am seeing 160/95 most of the time. Any suggestions? Any chance I could have a consultation with you on the May cruise?

    P.S. I'm 62.

    I've been doing LCHF for about a year and had decent weight loss in the first 6 months, but then I plateaued. I noticed at the same time my blood pressure hadn't really improved much, averaging 145S/95D, so I altered my diet a bit by dropping protein intake a little more. Initially I started out 75F-20P-5C and then shifted to 80F-15P-5C. After a month my body fat was down to ~12% from ~14% and average BP was better but not great at about 135S/85D. Then I made one more change to my diet by adopting an intermittent fasting strategy similar to Fast5. The 5 hour window didn't work well for my schedule so instead I will usually eat lunch at around 2pm and then dinner around 8pm. This last change really helped lower my blood pressure and now it's in the normal range usually measuring about 125S/75D.

    Other changes I would recommend are:
    1) If you work in an office, get a stand-up desk and try to sit no more than 4 hours per day. I did this a couple months ago.
    2) Try to do some moderate exercise about 3 times a week. I have a 10 minute high intensity morning work-out borrowed from Mark's Daily Apple.
    3) A few times per day stop, close your eyes and intentionally try to slow your breathing and heart-rate - sort of a mini-meditation.

    High blood pressure and heart disease run in my family and so I'm hoping that by adopting the strategies above I can stave it off as long as possible.

    What about the new study that said eggs are as bad for you're health as cigarettes!

    Do you mean the study that is referenced in this story:

    This story is almost 2 years old and doesn't seem to have been taken seriously. In fact, the New England Journal of Medicine reported on a case study of a man who ate two dozen eggs a day - every day - for years - and reported to adverse effects to health. That's a little extreme, but should give some credence to the fact that eggs are not the killers that the AHA make them out to be.

    I hope there not killers as scrambled eggs are one of my guilty pleasures along with skirt steak!

    Would agree with LC in #3. Also check early morning blood sugar over a week.
    Add some HIT: I try to exert myself 3 times for 30-60 seconds with 3x time rests in between, once a day.
    The last bout to exhaustion. But build up over time, well after gone low carb to avoid any MI !
    The HIT seems to clear out something every time and makes more energy available for hours after. "Gives" much more energy than it takes. Great investment!

    I am 67 now and I had the same high blood pressure you speak about for years before.
    Today it is 125 -140. Still a bit high, related to some belly fat still left.
    Now I aim for "metabolic renovation" which means to get rid of the last of the visceral fat (VF), just by measuring waist alone. Then morning blood sugar and BP should also find consistently low values since long term old VF is effecting function of pancreas, liver and heart.

    CVD is closely associated with higher blood sugar ( from food, from stress , from smoking AND persistent lost proper regulation due to VF after all the first causes eliminated!).
    Without "metabolic renovation" the system will never be able to regulate BS properly, and with it even diabetes-2 regains normal blood sugar control.
    Also be careful with milk proteins in cheese and maybe also butter. They tend to raise morning blood sugar which is a main daily hurdle to get rid of what is causing it and may also have other less known effects.

    I am surprised that others report higher blood pressure. My glucose, A1c, insulin are great. BP less than 120/80 and BS in the high 70's to low 80'3

    Maybe you have some sugar or higher carb than optimal for YOU or include seed and nut oils higher in omega 6 etcetera?

    for me I try to limit my carbs to 1) trace in cream 2) trace in eggs 3) gluconeogenesis from the body 4) accidental or incidental carbs that find thier way into our food. [20 grams o less on average]

    Mechanism that makes tumor cells sugar addicted discovered
    Date:April 4, 2014

    Summary:Cancer cells feel a special appetite for a type of sugar called glucose, research demonstrated nearly a hundred years ago. The tumor uses glucose like a sports car uses gasoline -- it depends on it to burn faster, to grow and to multiply rapidly. In cancer cells, glucose superaccelerates cell division in what is known as the Warburg effect. New research shows that in one in four human tumors, there is an excess of glucose receptors in the external face of the cell membrane and this protein acts as a magnet attracting all the glucose from the bloodstream.


    While IMO most if not all culd benifit from less or no glucose and low to no carbs; those with certain genetic markers like some SNPS or CNV's (Copy Number Variation) should know A) they have an increased risk and the option of HFLC could reduce and or eliminate the risks. Eric
