What are Phytosterols?

Keywords; what are phytosterols, cholesterol lowering plants, beta sitosterol, functional foods.


These are very important plant fats; compounds with a structure similar to that of cholesterol. They control the movement of fluids in plant membranes and are found in small quantities in every vegetable we eat.

Don't be put off by the formulation below. This isn't a lesson in organic chemistry but it may be interesting to some. Notice that cholesterol and beta sitosterol have very similar structures.

I'm a chemistry major; hence odd references to molecular formulations throughout this chiropractic site. The finer structure is important, but I think you'll agree I do try to keep it simple.

Their similarity to cholesterol means that these phytosterols compete with the intestinal absorption of ordinary animal fats. Eating larger quantities of plant phytosterols increases the fecal excretion of animal origin cholesterol that we have consumed in say dairy products.

What's particularly interesting is that food scientists have repeatedly confirmed that phytosterols reduce the unfriendly low density lipoprotein cholesterol whilst not affect the friendly high density form; blood levels of the latter should be as high as possible. The high density version helps keep blood vessel walls free of atherosclerosis. Everyone with a cholesterol problem should know about phytosterols.

Don't take them in pill form; they are so easy to incorporate in your diet. What could be simpler than half an avocado per day?


Cholesterol lowering plant phytosterols

Ordinary animal cholesterol + an extra ethyl group which is ringed.

The American national cholesterol education program recommends phytosterol enriched foods as part of their prevention of cardiovascular disease program.

This is where naturopathic and medical doctors find themselves poles apart. The former say we should be eating more foods that are rich in phytosterols. Medicine says we should enrich food artificially with phytosterols and take drugs to lower cholesterol; at a great profit to the drug companies. If you know what phytosterols are, you can save yourself a mint simply by including them regularly in your diet.

There are many studies proving conclusively that the phytosterol compounds will reduce serum low density and total cholesterol and, what's more, in a short time.

A study at McGill University found that after only 10 days, with no change of diet, the addition of beta sitosterol had a significant effect on low density cholesterol in the blood. They concluded that these findings suggest that a significant lowering of low density and total cholesterol in the blood plasma can be achieved by a modest dietary intake of the phytosterols in a food such as soybeans.

Personally, I would rather enjoy the phytosterols in avocado to soybeans which are not my favourite.  In any case avos have even more phytosterols than soybeans, and chickpeas, almonds and extra virgin olive oil are also particularly rich according to webMD.  They recommend aiming for 2000 mg per day, but the average American diet has less than a quarter of that.


Functional Foods

Phytosterols are considered to be functional foods, meaning that they have health promoting and disease preventing properties.

They not only improve the health of blood vessels but there are numerous studies indicating their anti cancer nature; particularly of breast, prostate and colon cancer. More, they have powerful anti oxidant properties.

The phytosterol beta sitosterol and the prostate gland are often mentioned in the same sentence. 

Conditions of the prostate gland like prostatitis which is now recognised very frequently to be a non infective condition, benign prostate hypertrophy which is really just a non cancerous enlarged gland, and prostate cancer which is the leading malignant and fatal cancer of men are all common in older men; they occur regularly and are particularly nasty.

The maximum urinary flow rate at which men can pee is reduced by prostate enlargement.


Squaws wouldn't understand perhaps since they tend to have the exact opposite problem; a leaking bladder is a known side effect of having taken post menopausal hormone replacement therapy. In brave talk, men have an air lock; it's difficult to initiate urination, and the stream is weak and slow. It takes for ever to have a sweet pee.

Perhaps worse, braves are unable to empty their bladders completely. The post void residual volume of urine is increased, meaning they have to urinate more often, and often have to get up several times at night. Disturbed sleep leads to other problems, not least of which is short term memory loss. Residual urine leads to bladder infections.

Non bacterial prostatitis, also called chronic pain pelvic syndrome, doesn't respond to antibiotics. It's a nasty condition causing men to visit the toilet more frequently, with urgency as they are unable to empty their bladders. In short, men suffer from difficult, painful and frequent urination.

It responds best perhaps to a prostate massage; a non painful but awkward and embarrassing procedure by which your doctor, and some chiropractors, massage the prostate, via the anus, for about two minutes. For my money, that's what I would do, rather than have a prostate operation which often leads to impotence. You're looking at a two minute embarrassment once a month as compared to the risk of permanent impotence? For me it's a no brainer.


Better still, and preferably before the symptoms start, this is the day to begin making sure you are eating adequate quantities of phytosterols.

However, in the event that you have already started with chronic prostate problems, there is very interesting research that beta sitosterol, a common phytosterol, has a very significant effect on the prostate gland.

A typical avocado weighing about 170 grams would contain roughly 130 milligrams of beta sitosterol according to Duester, writing in the journal of the American dietetic association.

In a powerful randomised, double blind, placebo controlled research project, the gold standard of research, men gained dramatic relief within six weeks from taking 130 mg of beta sitosterol daily. Not only did their symptoms decrease, but the residual urine in the bladder as determined by ultrasound scans and the flow rate improved dramatically.

Eating natural phytosterols as in avocados has no side effects; however there are concerns about taking it in pill form as there is also inhibition of the absorption of the fat soluble vitamins such as vitamin E. It's a completely natural substance that you should be eating every day. They are God's gift to the prostate.

A person enjoying plenty of fruits and salads might eat nearly 1000 mg of phytosterols, of which a large portion is beta sitosterol per day, but the meat and potatoes man might have almost none

Beta sitosterol

Research concludes that beta sitosterol is an effective treatment for benign prostatic hypertrophy.


Results

There was significant improvements when comparing the treatment of benign prostatic hypertrophy with beta sitosterol as compared to a placebo; the  quality of life especially was much improved. There were also significant improvements in the maximum urinary flow rate, and a decrease in the post voidal residue in those treated with beta sitosterol. 

The conclusions of the researchers is as follows; these results show that phytosterols and in particular beta sitosterol are effective in the treatment of a benign enlarged protstate.

What are phytosterols? Sesame seeds

The Journal of Agricultural and Food Chemistry reports the amounts of phytosterols present in nuts and seeds.

Sesame seeds have the highest total phytosterol content (~ 400 mg per 100 grams), sunflower seeds (280 mg/100 g), pumpkin seeds (265 mg/100 g).

The main problem with sesame seeds is that you have to "fletcherise" to get the nutritional value from them. Chew each mouthful 32 times! The best alternative is to grind them in a cheap coffee grinder and make them into Tahini, a sort of sesame "peanut butter", only nicer,  and not spoiled with the addition of sugar, chemicals and hydrogenated oils.

Tahini is widely used in the Middle East in various foods such as hummus. Rich in phytosterols. What is SESAME TAHINI ...?


SEED OILS

Various seed oils such as sunflower, rapeseed (Canola) and corn oil are rich in phytosterols, and are in fact one of the best sources. Phytosterol sitosterol (beta) is one of the most abundant of these cholesterol-lowering plant phytosterols.

This phytosterol complex is particularly heat labile; easily destructable.

Extraction of these seed oils involves multiple chemical extractions, heating to very high temperatures, refining, degumming and bleaching which results in a loss of 10-70% (Kochhar, 1983; Phillips et al., 2002) of the phytosterol in comparison with their crude oils, or just enjoying the freshly ground seeds. A simple coffee grinder in every kitchen for grinding seeds and spices is a must.

Furthermore, Piironenen et al found that the refining regimen causes significant oxidation and other intermolecular transformations of phytosterols.

Try and find cold pressed oils. Better still, enjoy olive oil; it's all cold pressed.


PHYTOSTEROLS AS A FOOD ADDITIVE

Farquhar et al. found that artificially adding a beta-sitosterol extract made food products unpalatable and unmarketable. Its chemical properties make it "difficult and inefficient" as a food additive. For more details read this link Biocatalysis and biomolecular engineering.


CONCLUSION @ WHAT ARE PHYTOSTEROLS

It really shouldn't be necessary for us to take extra phytosterols. If we eat them every day, we are far less likely to get raised cholesterol, prostate hyperplasia, haemorrhoids, varicose ulcers and many cancers.

They are found in all vegetables, salads, seeds and cold pressed oils. Fruit oils, from the olive and avocado too are rich in beta-sitosterol - up to 2%.

A friend confided in me: having an operation for piles is like having a roll of barbed-wire stuck up your rear-end.


So, now you know what are phytosterols ...



A phytosterol lunch

Did you know that you can literally make your own authentic hummus recipe in only four minutes? Well, that's my record; it's very cheap. I make 500ml of hummus twice a week. Chickpeas and freshly ground sesame seeds, the chief ingredients of hummus, make this into a phytosterol lunch! This my lunch today...



Whole wheat incidently is listed amongst those foods containing the greatest amount of phytosterol. Baking your own low GI bread is a cinch if you have a bread maker.

So, hummus made with chickpeas, olive oil and sesame paste, fresh whole wheat bread and avocado, salads... more than enough phytosterols to earn the butter on your bread.

HUMMUS AND HUMUS!

The key to healthy vegetables and fruit from the garden is humus, the break down product of your garden cuttings and clippings, plus all the vegetable waste like apple cores, eggs shells and potato peels from your kitchen. It's really not difficult, though turning the compost pile takes a bit of muscle work. Beats going to the gym. STARTING A COMPOST PILE ...

Hummus acts a wonderful phytogen, or flavour enhancer, to your meal. It makes an perhaps otherwise chewy salad meal palatable. In spring you may have avocados in abundance, but in the autumn there is an abundance of coloured salads from the organic garden. Can you count 10 coloured foods, all rich in phytosterols?

You may say, I don't possibly have the time to grow all these vegetables. True, I'm semi retired, but I also find time to treat half a dozen patients in need of chiropractic help most days, go gliding on Saturdays, trout fishing this weekend, and I've started my next book in The Family Affair series. The space created for gardening is made by turning the television OFF! Not that I don't watch some sport and the odd film.

That's cheese and pickled jalapenos on our low GI bread on the left. A rich, very filling and non fattening meal. Only the butter on the bread is slightly questionable; I won't eat margarine, but I could have used olive oil on the bread, it's true. When you eat as many foods that lower cholesterol that we enjoy, then you certainly don't have to fuss with statins and worry about raised cholesterol.


Two kinds of lettuce, young spinach, sweet basil, fresh corn on the cob, picked only half an hour ago, radishes, pepperdews, tomatoes without pesticides, hummus with parsley and mint.

As one surgeon put it, rather neatly, if we got back to eating the foods that our grandmothers served, rather than what our mothers taught us to eat, we wouldn't have those heart problems.

Interesting challenges of the day

1. Mr D has very severe midback back. He bent and twisted, feeding his son, and then laughed. Every breath is a nightmare. A sprung rib is every chiropractor's delight. He or she has golden hands. 30 percent better after one treatment.

2. Mrs C has a long history of severe, disabling migraine headaches since having her wisdom teeth removed. She clenches her teeth at night. After six treatments she has no migraines but some jaw joint discomfort remains; a bite plate is in the offing.

3. Mrs U has the trophy for the worst back this year. After major surgery with plates and screws two years later she still had paresis in the lower leg and severe disabling back pain. She's doing far better than expected, in no little part due to a lift in her shoe for a very short leg.

4. Mr V is 86 years old and hurt his back helping his wife into the car. Just one treatment of the sacroiliac joint and he's eighty percent better. It's not always like that.

5. Mr W lay on his back knocking down a pillar. Turning his head causes severe vertigo. He needs the Epley exercises, not pills, research shows. Update, he's fine.

6. I myself had an acute exacerbation of a femoral nerve lesion last year. One immediate treatment by my colleague has fixed the pain in the lower back, but there's some residual numbness in the lower leg; no soaring tomorrow alas.

7. This lady is a 86 year old woman with a 63 scoliosis. Chronic lower back has been her lot in life but she's well pleased with chiropractic and comes for chiropractic help once a month; some conditions you can never cure.

8. She is an 78 year old woman, is doing remarkably well with a bad sciatica. But over 200 pounds she is not losing weight; in fact, gaining despite my suggestions. She's high risk for a stroke. I have referred her to a dietician to crack the whip.

9. A 61 year old man with upper cervical pain yesterday; it's not severe but also not getting better of its own accord. He's afraid it may turn very acute as when I treated him three years ago. Since then it's been fine. 

10. A 64 year old woman has had scheuermanns disease; it's left her with a spinal kyphosis and chronic middorsal pain. She responds well to chiropractic treatment provides she come every six weeks or so for maintenance treatment.

11. Mrs C has been having severe headaches, and taking a lot of analgesics. It's a non complicated upper cervical facet syndrome, and she's doing well.

12. Mrs D, a middle aged woman with hip pain of one year duration, despite other treatment. Xrays reveal an impingement syndrome and early hip arthritis. There's much to be done.

13. Mrs B has had one of the nastiest of conditions; vertigo caused by a disturbance in the inner ear. Falling repeatedly and vomiting she consulted her doctor but medication didn't help. After two sessions of the Epley manoeuvres she was 50 percent better. After two weeks 75 percent improved. No longer vomiting all falling. She's not enjoying the Brandt Daroff home exercises.

And so the day goes; chiropractors shouldn't be treating the elderly most medical sites state but that's so much bunkum.

Greetings, Dr B.
You helped me quite some time back with a soothing and professional response which turned out to be exactly correct. I now consult a local chiropractor. You write a superb newsletter, too.

Your own unresolved problem. Pose a question

Knowing that up to 70% of the time the correct diagnosis is made with no examination, no special tests, no xrays, but just from the history, there's a fair chance I can add some insight to your unresolved problem. But at least 30% of the time, I may be quite wrong! Give plenty of detail if you want a sensible reply.


You visited this chiropractic help site no doubt because you have a problem that is not resolving and want to know more about what chiropractors do.

The quickest and most interesting way is to read one of my ebooks of anecdotes. Described by a reader as gems, both funny and healthful, from the life and work of a chiropractor, you'll love them. Priced right at $2.99, though Kindle fiddles the price without telling me.
