Pathophysiology of atherosclerosis is irreversible; only prevention makes sense.
This is a long page and one of the most important at this site, if you want to live long in the land. Only read further when you have time to ponder.
So, you have been told you have a damaged aorta or, perhaps worse still, hardening of the cerebral arteries. Actually, in this latter case, it is likely your family that would be told; by the time it has been diagnosed there is a good chance you have already lost your marbles and will not have a clue about the diseases of blood vessels.
Atherosclerosis, or hardening of the arteries, is a disease of civilisation. It's common in all Western societies and rare in those that have not come in contact with urbanisation.
It is also known as arteriosclerosis.
This page was last updated by Dr Bernard Preston on 24th February, 2022.
It is much worse in diabetics; type 2 is strongly associated with our Western lifestyle. Obesity is the number one cause, and interestingly those who consumed artificially sweetened beverages were even more at risk than those who enjoyed their sugar colas.
Those who had artificially sweetened colas every day had an increased risk of 2.21, but those drank sugared beverages had a smaller, but still significant probability of 1.34 of getting type 2 diabetes, report researchers who followed 66,118 French women over fourteen years. It is published in the American Journal of Clinical Nutrition in 2013. (1)
The side effects of artificial sweeteners are even worse than drinks with sugar when it comes to glucose intolerance, metabolic syndrome and diabetes.
Yo-yo diets also significantly increase the risk of cardiovascular events, report researchers in the New England Journal of Medicine. (2)

Pathophysiology of atherosclerosis causes hardening of the arteries.
The next steps in the atherosclerosis disease process are
All in all, the pathophysiology of atherosclerosis is extremely complex and still being unravelled by scientists.
It's long been known that unrefined oats is the most powerful foodstuff in the fight to lower elevated bad cholesterol, a big factor in the causes and prevention of atherosclerosis. Quaker Oats recipes ...
In general unrefined grains promote greater well-being of the blood vessels, but they are hard to get and there's a lot of deceit in the milling industry. That term wholemeal is usually a big fat lie.
A researcher at Tufts University, Mohsen Meydani, working in the pathophysiology of atherosclerosis and nutrition has now proved that oats does much more than simply lower blood cholesterol. Oats contains an antioxidant that prevents sticky blood cells from adhering to the walls of damaged arteries, even reducing hypertension, for example.
Control of blood glucose is also central in the prevention of atherosclerosis. With nearly a half of folk in the Western world showing signs of prediabetes, it is little wonder that cardiovascular disease is so prevalent. The solution, unpopular though it may be, is the avoidance of all refined carbohydrate.
It may seem hard to believe but in many Western countries the average person consumes 6 cups of sugar per week; that is over 40 teaspoons per day. This is one of the prime causes of obesity and diabetes, and the reason why Covid-19 deaths have reached half a million in America.
Can you imagine 150 pounds of sugar in one year? That is what the average person consumes; then you get health nuts like Bernard Preston who has almost none. Some people are having far more.

Here are the back issues.
Work is continuing on how oats not only reduces the inflammatory changes that build up in arterial cells walls damaged by atherosclerosis disease, but also helps by reducing the proliferation of damaged smooth muscle cells than line the inner walls of all arteries.
So, do not be totally despondent if you have been told you have atherosclerosis of the aorta for example, the very large artery that supplies the bowel and legs.
Whilst attempts to reverse atherosclerosis are probably in vain you can do much to prevent the further proliferation of atherosclerosis symptoms and disease at this site of inflammation and at new sites.
How much a loved one with cerebral atherosclerosis can be helped is less certain. But what's the harm in trying 2-3 tablespoons of oats every morning for breakfast? Almost certainly cheaper than all the frosties, crispies and toasties on the market.
More, research is now suggesting that that raised bad cholesterol is not caused by animal fat; high glycemic carbs are the demon. Butter is back, and white rice and white bread are definitely out, as all the sugary bagels and refined flour goodies; chocolate cake and the like. Whoops, baddies, not goodies.
Just as important is researchers are now finding that the antioxidant in oats also prevents any cancer cells that line the inner wall of your bowel from proliferating too.

Even better is to cook enough oats for several days, cool it in the fridge overnight, and then use it to make your delicious oats breakfast; a process called retrodegradation makes it difficult for enzymes to digest the starch in the small intestine, and it passes straight through becoming a 'prebiotic' for the bugs in the colon that form healthy short chain fatty acids instead of glucose, with no insulin rush.
There's lots of research coming out now about the microbiota in the large intestine; feed them with this resistant starch that is not digested in small intestine and you'll be far less likely to become diabetic or suffer from an autoimmune disease like lupus.
The whole subject of phytochemical foods is obviously vast; one can labour and fret over it but, much simpler, is to enjoy a wide array of coloured and unrefined foods. Just the influence of walnuts blood pressure reminds us of the importance of a healthy breakfast menu.
Omega-3 fatty acids, found in certainly oily foods, but especially fatty fish, freshly ground flaxseeds, walnuts and to a lesser extent other nuts like pecans, are a vital part in the fight against cardiovascular disease.
They are "essential" fatty acids, meaning your body can't make them from other fats. If you do not eat omega-3 foods regularly, you will develop atherosclerosis of the arteries.

Dairy products remain controversial, not least because the milk from a free range, pasture dairy cow is quite different than that from the poor beast that's never seen a blade of green grass. Nevertheless, butter is back with a vengeance, and should probably never have been banned.
all depends on which artery is blocked. If it's one of the lumbar
arteries, then you are likely to have repeated episodes of lower back
pain, because the injured tissues in your back will simply not be
getting enough blood; atherosclerosis symptoms are complex and varied.
If it's the one of the coronary arteries, then chest pain with exercise will be the order of the day, as the heart muscle doesn't get enough blood; angina.
If it's one of the iliac arteries that pass through the groin on the way to the leg, then you will get pain in the leg WITH EXERCISE. As soon as you rest, the pain goes away.
If you love to read, enjoy this freebie from my third book, Stones in my Clog, fascinating anecdotes from Bernie Preston's chiropractic coalface. Is it possible that a chiropractor could diagnose a blocked artery that medicine had missed for two years? Nope, it wasn't sciatica after all as they told him. Two simple basic tests made the diagnosis, confirmed by an angiogram, but the old rule repeats itself again and again: IF YOU DON'T LOOK FOR IT, YOU WON'T FIND IT.
This is the arteriogram taken after Bernie referred his patient to a vascular surgeon. Truth be told: I wasn't surprised, but all his doctors were. Walking gave him pain in the calf and he didn't have a pulse in the ankle.

atherosclerosis is brain exercise. Feed your brain, have lots of laughs and not a few sober

The pathophysiology of atherosclerosis also weakens the walls of arteries allowing for a bulging of the artery known as an "aneurism". Aneurisms are silent and deadly; it all begins with inflammation and atherosclerosis of the aorta, for example.
As the blood pressure rises, caused by the general narrowing of the arteries forcing the heart to pump harder, the bulge in the aneurism silently increases in size. Then one day, poof... a bout of coughing, bearing down too hard on the toilet, a fit of rage, rushing across a busy street increases the pressure sufficiently to burst the artery. In the case of the aorta, the usual result is very sudden death.
A narrowing of the artery by atherosclerosis of the aorta simply reduces blood flow to the various organs, notably the kidneys, the intestines, the spine and legs.
Intermittent claudication causes pain in muscles whilst exercising, but quickly relieved by rest; it's a sure sign of an advanced stage of the pathophysiology of atherosclerosis.
This reduced blood flow to the legs produces a strange syndrome characterised by no symptoms whilst the sufferer is at rest, but pain in a muscle(s) starved of oxygen as soon as it is forced to exercise. Resting immediately alleviates the pain as the need for oxygen in the muscle is reduced.
Walking produces severe pain in the calf, cycling in the thigh muscle.
The sign your chiropractor will look for to distinguish between claudication and sciatica is the presence of the pulse in the ankle and on the foot.
Postmortem studies have found a strong correlation between artheriosclerosis of the aorta and degenerative disc disease; that means chronic low back pain. The tissues of the spine simply don't get enough oxygen to heal after injury resulting in the development of the difficult lower back.
Homocysteine is the normal breakdown product of protein metabolism. But it's highly toxic to blood vessels and is immediately converted into two other substances in the body. But this process is utterly dependent on certainly B vitamins and zinc; without them there is certain onset of inflammation in the body including the arteries; pathophysiology of atherosclerosis.
Folk who do not consume enough of these vital substances will have raised homocysteine in the blood. It's even more toxic than raised LDL cholesterol; perhaps surprisingly free range eggs for their choline and omega-3 are part of the solution.
One of the those substances is betaine, found naturally in beets, after which it is named, spinach and 100% whole wheat; high dietary intake decreases the inflammatory markers by more than 20%. It's one of the reasons why men enjoying whole grains for breakfast (but not if they are refined) have a 29% lower risk of heart failure.
That could be a whole grain muesli, cooked rolled oats, or just a slice of 100% wholewheat toast; many folk have stomach pain with a raw breakfast cereal. Best to my mind is eggs Florentine on a slice of 100% wholewheat toast; it contains plentiful betaine, choline, magnesium and all the B vitamins.
Fat in nature is entirely of the 'cis' type; to make it solid, food companies hydrogenate it to the 'trans' form; margarine is easier to spread on your bread that sunflower oil.
But there's a simply huge problem; trans fats, by the same mechanism as high cholesterol, inhibit the responsiveness of a growth factor in the inner lining of arteries that prevents atherosclerosis, or hardening of the arteries.
If you are taking high blood pressure pills, it's very likely because you were a smoker, or had a diet high in cholesterol or trans fats.
Food companies are compelled (in theory) to list trans fats, but by using damn lies statistics they manipulate the figures to conceal. 20% of the fat in Marmite for example is trans fat, but they list it as zero per helping. Bettercreme sucks is another.
Magnesium is a vital mineral easily lost in the water used to cook vegetables; it's very important to prevent the development of the pathophysiology of atherosclerosis in blood vessels.
There's quite strong research coming out now that adequate magnesium
in the diet is vital for preventing the inflammation that affects the
wall of the arteries, and especially those of the heart.
How much is adequate? About 400mg per day and not many people on a typical Western diet are getting enough. Unfortunately, taking it in pill form is not as affective as getting it from your food. Dark green leafy veg, beans, nuts; look no further than Swiss chard food.
The beauty of a diet rich in these coloured foods is that not only will you be enjoying the protection of minerals like magnesium, but also phytochemicals like the kaempferol and cancer prevention.
in Japan shows that getting enough magnesium will reduce your chances
of having a heart attack or stroke by a massive 50%. See how you can
EASILY increase the mineral from your food.
High serum phosphate is also associated with atherosclerosis; they cause damage to the inner lining of the blood vessels with consequent calcification leading to hypertension. It has long been known to be associated with chronic kidney disease, stroke and heart attacks.
That serum phosphate comes from two sources, one of which cannot nor should be avoided; meat, starches and legumes. It is impossible to lower that without cause a protein deficiency. In our food it is organically bound and only about a half is absorbed from the gut.
However, the other source, which is not organically bound, is almost completely absorbed in the alimentary canal; this is the cause of high serum phosphate and the consequent damage to our blood vessels leading to a host of serious diseases including blindness. Processed meat, ham, sausages, baked good and soft drinks are the source of this killer.
Food additives like flavour enhancers, preservatives and those that preserve the colour of our food are particularly high in phosphorus; and those that help retain moisture in baked goods too.
For plants, going to seed is a normal part of the cycle of life and death.
But figuratively speaking, it's the avoidable part of slipping relentlessly towards an early, premature demise. And no where is it seen more clearly than in the aging of our blood vessels. When they are unable to get fresh, nutrient rich blood to our body parts, it is the beginning of the end.
Not much is written about the venous return of blood, but it is important too. There is new research coming out that even diseases like MS may be caused by a poor vascular system removing wastes from the brain.
Whether it's the brain, the heart, the musculo skeletal system, the pathophysiology of atherosclerosis is a subject that should absorbe us if we plan to live to a healthy and hearty eighty, with all our marbles intact. Have you heard of blue zone longevity? Ten times as many people live to 100 and still strong in their nineties is not unusual.
A good place to start is grinding flax seeds.
Foods to reduce inflammation is primarily about blood vessels and atherosclerosis, but also concerns the pain in muscles and joints. For example, the capsaicin health benefits in the chili family give protection to the body; we particularly like growing peppadews which can be hot but are milder than jalapenos and much less fiery than most of the pepper family.
Having said that, this green chili sauce recipe is a great favourite.
