"In univariable mendelian randomisation, genetically elevated apoB in participants was identified to lead to a shorter lifespan in parents (fathers: 0·89 years of life lost per 1 SD higher apoB" that is a very tiny effect. also , i doubt they analyzed extremes(non linear effect) . so is a very very low apo-b good? i doubt, based on evolutionary arguments.

[@rollingrock3480]

I eat 5-6 eggs a day (big omelette), I have a family history of heart disease, but my bloodwork is stellar. It's nice to get more information on this, especially after the dietary cholesterol limits were removed.

[@yohandsome]

While dietary cholesterol apparently has a much lower impact on the progression of cardiovascular disease than previously assumed, both animal experiments and human studies seem to support the view that dietary cholesterol may contribute to the transition from benign steatosis to the potentially fatal nonalcoholic steatohepatitis in the liver. So dietary cholesterol may be harmful to the liver, in particular when administered in combination with polyunsaturated fatty acids, which favor lipid peroxidation. www.ncbi.nlm.nih.gov/pmc/articles/PMC6726297/

[@robertusga]

How do you define "stellar"? Eating eggs does not raise cholesterol much. It's saturated fat that will do that trick in most (not all).

[@steffshorr]

Such great explanations!! ASCVD and ApoB deserve our attention to lessen our risk. This isn't taught in school, why?❤

[@Pustul]

I’ve listed to a lot of podcasts from Peter on this topic but the question of how to lower your apoB level non pharmacologically, especially when you are in your 30s and still have a chance of affecting it, is never approached. I know a ton on how cholesterol works and how it kills people but nothing on how to prevent it from killing me.

[@curious_boy9092]

you need to lower saturated fat and raffined carbohydrates.

[@xavierbotteri1950]

Dear Peter, Could you please give us a quick update on the LpPLA2 marker? Do you still believe it is the best marker of arterial inflammation, as you once said during one of your conferences? Thank you very much.

[@DebiDalio]

To give you myself as a data point (since you ask why people don't want to take statins): Female, 64 yrs old. In July 2022: Cholesterol total 271, HDL 86, LDL 170, Triglycerides 48, APO A1 199, APO B 115. (I hear Peter screaming, get on a statin now!) I have recorded 26 cholesterol test results taken from 1988 to 2022. Half of them are a cholesterol total over 250. Why have I so far refused to take a statin? Side effects. I'm not willing even to risk them on a trial basis. Side effects such as: headache & dizziness (I already have a problem with vertigo and migraines), feeling unusually tired and weak (I already have enough problem with that), digestive system problems (I was recently in the hospital for two days with severe constipation problems, so I don't need to take yet another drug that has that as a side effect), sleep problems (I'm already taking two drugs that attempt to fix my sleep problems), muscle pain (I have enough pain from arthritis, I don't need more). My theory is if I have a good diet, no stress, and get some regular exercise, then I should have a low level of inflammation in my body and therefore should not be prone to having an ASCVD event. Both of my grandmothers lived into their 90s. My father died at 87. He had dementia and smoked for half his life. My mother is alive and well at 86. Nobody in my family has ever even mentioned anything about cholesterol to me. Maybe I'm just being foolish, and I am open to more arguments, but I will take a lot of convincing that I need to be on a cholesterol lowering drug for the rest of my life. Having said all that, I thought this and other podcasts on this topic were fascinating and informative. Keep 'em coming.

[@endgamefond]

Do you take it now btw? Do you the cause kf your original headeach and migrane btw?

[@DebiDalio]

[@Eldooodarino]

I don't believe that age causes BP to go up. Here's an N=1 story. Five years ago my weight had gotten a little high BMI probably 27-28 ish. I had severe sleep apnea both obstructive and central. A routine colonoscopy revealed a polyp. I was on a bipap machine for the apnea which I hated and my PCP was muttering about BP meds. Somewhere I read that "BP goes up with age but nobody knows why,." I told myself "Oh. Sounds like they're making stuff up." So I started eating 40-100 grams of fiber every day. I lowered my BMI to 25-26 and ditched the bipap machine, lost the apnea, lost my gout, lost my alcohol craving etc. My average BP over the last month is 105/67. I have no idea what works at the population level but but I know what worked for me.

[@metalrunner4398]

I am not sure about part around 55-56 minute where the gentleman says that around age 35 you can’t do much to lower apoB. Me and couple of my family members were in the range of 110-140 and changed diet and improved exercise. It went down to range of 60-70 in all of us. I mean, we did not conduct a legit study but it tells a lot.

[@santiagojaramillo3079]

What changes did you make?

[@metalrunner4398]

@@santiagojaramillo3079 We eliminated saturated fat rich foods, increased fiber to at least 60g per day and introduced foods that are proven to lower apoB such as plant sterol rich food, soy protein (tofu, edamame, tempeh, soy milk), insoluble fiber (oats, berries, legumes) and PUFA rich foods. Also I am spending at least 3-4 hours a week in zone 2 training with 2x30 min strenght and 2xHIIT a week. What has surprised me, my HDL also increased but slightly. Tryglicerides were 98 now they are 46.

It would be helpful if the term cholesterol were left behind once they become incased in the lipoproteins because that changes their identity. Although cholesterol is present, they are different and calling them what they no longer are makes for confusion.

Both. Bursting can cause a clot that can't pass a narrowing farther downstream.

both...

Thanks for a great episode. Peter mentioned a lady patient with scary metrics who he chooses not to treat aggressively because she has zero calcium score in her 60s. Any suggestions for someone who is the opposite of that - ie athletic, good weight, low LDL-C, BP, eats healthily but mid 50’s with a CAC of 70?

[@alecto42c]

Have you had your lp(a) checked?

@@alecto42c I just requested for the first time and it came back 2.9 mg/dL. Not sure how good that is, but result sheet shows

[@alecto42c]

@anglosin Yeah, lucky you! That's great. Are you an endurance athlete, long runs? Usually elevated CAC when all other markers are good can be associated with long distance runners/swimmers, ex-smokers/heavy drinkers, or someone where endothelial dysfunction was present

[@anglosin]

@@alecto42c Interesting! Thank you so much. Yes, I do distance running in a very hot, humid climate (Singapore). I will try to find literature on that association but if there is anything you can recommend that would be much appreciated 🙏🏻 Presumably the elevated CAC carries all the same risks, even when other markers are good? Is giving up running the only way to mitigate? Endothelial dysfunction I guess will be difficult to determine…

Can I get APoB in a low enough range without drugs?

@@dawngonzalez508 fwiw I'm much healthier than 2020. At the time, my ldl was over 160 and a1c 5.7. I was prescribed statin. My doctor said you are welcome to not take it, tho I have to write it up for you. I researched abit and set up some (health) metrics goals. I gave myself 4 months. If I didn't see any improvement, I'd start to take them (statin). Anyhow, I did improved enough to skipped them. My a1c is ~5.3, ldl is ~150 and my triglycerides and hdl also improved tho not "optimal". I also decreased my waist over 2 inches. My bp was always pretty good. And I'm slightly younger fwiw.

[@rualablhor]

@@erastvandoren that is very ambitious. It would take months, If not a year, at least. I don't know...if one is healthy otherwise, I'd aim for ldl 130, which is my ultimate goal.

[@johnmatthews6943]

Can anyone explain what is the difference between non-HDL cholesterol and apoB in terms of lab blood tests, meaning what is the difference between what those lab tests measure?

[@rualablhor]

Afaik ldl in the regular lipid panel is calculated, not measured. And it is not in number of particles but mass. Thus, you could have different particles bc their size/weight could differ greatly. ApoB is the actual number of particles period, it's more accurate than ldl. Ldl estimates would work for most, most of the time... except when it doesn't.
