For example, Looking at time index 1:35:0. we can see that in that trial LDL has a p-value of .34. so (sarcastically) we see it is is clearly a significant causal factor as that is much less than .05. Looking at the factors that were actually significant: glucose, hba1c, Trigs, waist circumference, the are generally improved with low-carb, but gotta watch out for that LDL.

There are also studies that suggest the bacteria that cause cavities can be passed from parent to child by sharing items.

    An additional mechanism? (an informed hypothesis)
    Blood sugar spikes (among other factors) wash out the vascular endothelial glycocalyx. This is a structure that is not shown in medical textbook illustrations. It is only recently that it has been visualized _in vivo._
    The glycocalyx acts as a shield for the endothelial layer. It is also a 'flow sensor' and controls the release of Nitrous Oxide (NO) for BP control (vasodilation).
    It takes the glycocalyx multiple hours to recover. With the shields down, the endothelial layer is exposed to toxins, oxidized products and LDL remnants. Continuous consumption of carbohydrates never allows the glycocalyx to fully recover.
    It is a one-two punch, a binary explosive. Excess inflammatory factors *WHILE* the shields are down. If you study just one factor, you might miss it (as you clearly stated).
    Why would we have such a fragile structure for these mechanisms that protect us?
    The flight-or-fight response. "Adrenaline (later, cortisol continues the response) is released which triggers the release of blood sugar (glucose) and fats from temporary storage sites in the body. These nutrients flood into the bloodstream, supplying energy to all parts of the body."
    The glycocalyx is washed out, preventing the release of NO and causing blood pressure to rise as heart rate and blood flow increase. That gets the energy and hormones to every nook and cranny of every capillary.
    This does increase our exposure to the {toxins}, but _Desperate Times Call for Desperate Measures._
    Being in that state chronically (for one example, sleep apnea) is deadly.

      By that explanation, regular exercise would cause the same thing as it raises blood sugar. But, I would like to know that you're not just repeating someone like Cywes and did your own unbiased medical literature research. At what point of blood sugar does the glycocalix get washed out? Why do high carb eating traditional diets end up living longer on average? They're more nuance. Mechanistic does not equal evidence to follow unless there's clinical research to back it up. There's always a million mechanisms going on at once and the benefits might outweigh the cons in practice.

      According to the research on the glycocalyx also high LDL-P washes away the glycocalyx. (Tested with LDL injections) Not that you said that this mechanism does not exist, but I think this is important to mention when talking this topic.
      Also, it is very much possible that NO production is required for nutrients/blood to get to the tiniest blood vessels, no matter the level of blood pressure because there is a mechanism that closes the tiny blood vessels in sensitive tissues, like in the brain and organs, when high blood pressure is detected. This mechanism is proposed as an explanation for how sodium overload can cause migraine and other issues in some recent studies.

What if a predator was watching him and planned a sneak attack? Would glucose spikes help him to get away? Grab more hanging berries or fruit when he fled from his attacker and found a "safe" place? Ate the food quick before he his opponent approached? Ran away again, then climed a fruit tree with a bird nest?

    Spike info @1h39min: A semi informative home method is to buy your own glucose meter (cheap at pharmacy) and check glucose levels every 10 to 15 minutes after typical meal. Get a baseline before meal or know you baseline. Your spike should be at about 1 hr and back to normal at 2 hours. Do several times to get a sense of your response. Typical peak for a meal should be around 150 or less. Much higher routinely is not good. My response is good (tested many times) and I am on a high carb plant based diet (complex carbs). HbA1c at 5% plus minus 0.1%. Also, protect your arteries by keeping blood pressure low. Good diet, and exercise, can help here as well.

    Good presentation. On the elevated inflammation markers, you might be interested to know that a study from the Sonnenburg Lab (Stanford) showed that eating fermented foods slightly reduced many inflammatory markers (19 I think). Since chronic inflammation is implicated in aging via many disease states it seems a worthwhile goal to keep chronic markers low, which means healthy glucose levels and if Sonnenburg study is borne out to eat fermented foods.

    It's on a spectrum. Obviously, sustained huge spikes are likely to be indicative of other factors that aren't great.
    But, at its core, every time you eat carbohydrates there is **some** spike. It's not inherently bad; it's a normal part of the response process to food intake.
    Beyond that, I would not extend any sincere concern to the basic physiological response of insulin to food intake. Particularly if, as you mention, you're otherwise healthy and active and eating well.

    another thing that's important to note here is the difference between glucose and fructose when it comes to ROS production and mitochondrial overload- the former has many regulatory stopgaps to slow down processes like glycolysis (ex PFK1) in the presence of excess energy, whereas fructose bypasses these safeguards because of where its processing dovetails with glucose metabolism. It's a lot easier to achieve the necessary conditions for mitochondrial overload through fructose consumption than glucose/starch

      @@Physionic Yeah, but my theory there is that if you have only a few factors that oxydate and glycate LDL, the body is perfectly able to clear them. And at that point (for ex LMHR) it matters little how much LDL you have, you will have very little or no artherosclerosis. On the other hand, past a certain level of oxidation and glycation, the more LDL you have, the more you get plaque formation. But since most of the general population is either pre-diabetic or anyway has frequent glucose spikes (even just eating bread before everything else in every meal + snacks etc), we observe this causal effect of LDL on CVD.
      Just a theory, but for now it seems to explain most of the articles I read on LDL and glucose.
      Does this mean that low carb is the only way? Of course not. And other problems can arise from blindly going low carb (seed oils, for one).

    Just cut simple carbs in your diet as much as possible. Sugar, deserts, most bread, crackers, processed crap food- and you shouldn’t have these spikes. It’s the same advice literally everyone gives. Complex carbs (veggies) = good. Sugar = bad. If you do eat simple carbs - eat them with some protein.

      I've read countries studies, I'm so very tired of old fashioned studies.
      Any study that has government money should be required to publish raw data which would allow anyone to in effect do their own studies within a study, even crossing participants from various studies coming up with their own conclusions rather than relying on hire others decided to group people... For example.
      You talked about after meal glucose spikes and insulin resistance, but this could also be a sedentary post meal life.
      That same person might have less spike if they went walking and that supposed insulin resistance might disappear.
      These studies could be better suited for real research if they documented baseline blood work in detail.
      At the end of studies rather than looking at results of a group with his and lows and trying to come up with a meaningful average, it would be better to take the individual with the high and back track the details of that one individual to understand why that result occurred.
      For example how many people had a sub optimum Thiamine level?
      How many outliers in many studies might back track to that cause, or any of various things.
      Or as mentioned previously, who did post meal exercise that wasn't documented and would skew results.
      The variations in results don't happen by magic but studies the way they are done now don't care, it's valuable lost data.
      I guess this is not important if your trying to sell your insulin provoking drug.

    OK - Here's a topic you HAVEN'T covered: Both "low carb" ( high protien & fat ) and "low fat" ( high carb ) diets works for weight loss. And I know there is "carb cycling" which uses percentages of each macro. BUT WHAT IF - you ate only carbs one day, fat the next, and protien the next, on rotation. ie. Kind of cycling the polarised weight loss approaches. Carb day would increase insulin high but with no fat to store. Fat day would be low insulin so no fat storage. Protien day would be your non fattening 'meat fix' ... and so on. Would this complete separation of macros help weight loss ???

    Homo sapiens and our closest evolutionary relatives evolved eating a high carb, low fat diet. While high fat diets can improve short-term markers of glycemic control and insulin sensitivity, they may also mask underlying insulin resistance by reducing carbohydrate intake. This means that poor insulin sensitivity might not be directly addressed but rather managed by the diet's restrictive nature.
