Healthy smoothies

I've now seen several people who have either caused themselves to be diabetic or to have other phenomena associated with excessive consumption of carbohydrates, all by innocently indulging in a carbohydrate-packed smoothie every morning.

Kay, for instance, has a smoothie of a half-pint blueberries, a banana, a scoop of whey, low-fat yogurt, a cup of milk every morning. The rest of her diet was fairly healthy: salads with oil-based dressing for lunch, salmon and asparagus for dinner, only an occasional carbohydrate indulgence outside of her morning smoothie ritual. Yet she had a HbA1c (a reflection of prior 60 to 90 days average blood sugar) at the near-diabetic range of 5.9%.

The mistake most people make when making smoothies is relying too heavily on carbohydrates like fruit. A smoothie like the one made by Kay can easily top 50, 60, or 70 grams carbohydrates per serving, more than sufficient to send blood sugars up to 150 mg/dl or more.

So what can you put in your smoothie and not send you over the edge to diabetes, small LDL, and all the other undesirable phenomena of excessive carbohydrates? Here's a list:

--coconut milk, unsweetened almond milk. Less desirable: milk, full-fat soymilk
--ground flaxseed
--oils: flaxseed oil, coconut oil (melted), extra-light olive oil, walnut oil
--dried coconut
--extracts: vanilla, almond, coconut, cherry, hazelnut
--spices: cinnamon, nutmeg, ginger
--herbs: mint leaves, cilantro
--cocoa powder (unsweetened)
--nut or seed butters (peanut butter, almond butter, sunflower seed butter)
--tofu
--exotic ingredients (ingredients you wouldn't expect in a smoothie): spinach, kale, cucumber

How do you sweeten a smoothie? This is what trips up most people. If you resort to fruit like bananas, pineapple, or apple, you will readily send your blood sugar skyward. Honey, agave syrup, and sugar, of course, all increase blood sugar and/or have the adverse effects of fructose. Be careful of yogurt, also, for similar reasons.

Therefore, to sweeten your smoothie, consider:

--Small servings of berries, e.g., 8-10 blueberries, 2 strawberries, a few wedges of apple, half a kiwi
--Non-nutritive sweeteners like stevia, Truvia, sucralose, xylitol, erythritol. Also, sugar-free (sucralose-based) syrups like those from DaVinci and Torani are useful. (Just be aware that non-nutritive sweeteners can increase appetite--use sparingly.)

Also, note that, if you have divorced yourself from wheat, cornstarch, and sugars, your desire for sweet should be much reduced. Foods other people find just right will taste sickeningly sweet to you. You might therefore find that foods like peanut butter or coconut milk have a mild natural sweetness; added sweetness is only minimally necessary.

Coming next: I'll share a smoothie recipe or two of mine. Anyone want to share a recipe?

    Once I gave up artificial sweeteners in additon to added sugars, my sense of sweet changed dramatically.  A lot of foods I used to love are now sickeningly sweet.

    It took me months to adjust to my new taste buds, and initially, I was not thrilled about theh change.  However, it did remove the need for virtue to avoid sweets.

    I think it is safe to say that diabetics should generously include blueberries in their diets. Blueberries actually may increase insulin sensitivity, lower blood glucose, triglycerides and abdominal fat.

    Does anyone have any cookbook or recipe website recommendations for what ingredients I should eat? I've cut way back on sugar and carbs and have lost some weight. I'd like to take things to the next level, but I'm really struggling with finding recipes, especially with a variety of ingredients. I feel like eggs and veggies are the only foods "allowed". Thanks in advance for any help.

    Very nice topic.  While I minimize these for myself I make one for my 2.5 year old.  I has to many carbohydrates but the trade is to get some nutrients he would otherwise not get.

    This morning was 1/2 Banana, Coconut water 2tbs, 1tbs raw cocoa powder, Almond butter 1tsp, 1 egg from a local farm, heavy raw cream 1/4 avocado, 1 cup raw spinach.

    This is generally consumed by him over a full day so the overall impact is lower.

    Wow! Great ideas.

    I, too, prefer whole foods. But many people like the idea of making a smoothie and consuming it on the run, so I try to help them make healthier alternatives.

    Smoothies can be a delicious indulgence on occasion, too. My favorite is to combine unsweetened cocoa powder with peanut butter, along with unsweetened almond milk and some coconut milk. A little sweetener is required due to the bitterness of the cocoa. It tastes like a Reeses peanut butter cup.

    I am a long time reader of this AWESOME blog - thanks Dr. Davis for all your time and effort. Thanks also to all that comment - I read every single one.

    As Dr. Davis said, some excellent ideas here. I myself love a couple of eggs for breakfast but when the weather warms up I like doing a smoothie instead. Mine includes:

    4 cups or so leafy greens (organic baby spinach, kale, dandelion, collards etc)
    1/2 can coconut milk
    2 Tbsp coconut oil
    2 eggs (raw)
    a handful of frozen berries (maybe 1/4 cup)
    a drop of vitamin K2

    You can add darn near anything to this (fish oil, cod liver oil, other powdered or liquid supplements). It looks green but the taste is not objectionable. It is not sweet but the handful of berries makes it palatable without overloading the carbohydrates. I have tested my blood sugar after drinking this and most often even after only 1 hour, a nice even 78. I drink the whole thing for breakfast M-F and it fills me up until early afternoon. It also gives me a great sense of satiety that I don't get with anything else - I just feel good!

    For people who like having a smoothie/shake I really encourage you to add some leafy greens. I think the best one to start with would be organic baby spinach. It is very mild and an excellent way to add some to your diet.

    I've started making eggnog (sugar-free and alcohol-free, of course) for breakfast. I throw in my vitamins, too. I've choked on pills before, so this is a good way to take them.

    @Davide, the study you refer to is a rat study funded by people who sell blueberries. The article doesn't say what the rest of the diet was, but if it was low-nutrient pseudo-food that's sometimes used in rat studies, adding back pretty my anything with nutrients would have improved the rats' health. In real life, eating a bunch of fruit raises your blood sugar if you're diabetic.

    Hey, Doc.

    Blueberries are supposedly extremely healthful.

    You wrote something about 8-10 blueberries to put into a smoothie.  Is that the amount one should eat to get full advantage of their healthful properties without the disadvantages of their sugar?

    Can one eat more if combined with other low glycemic foods that will presumably blunt the effects of the sugar?

    Thanks.

    I've been diagnozed with pre-diabetes (fasting glucose: 105mg/dl, HGB A1C 5.8%) last July and have since then been trying to lose weight and change my diet. Luckily, my lipid panel seems ok (Chol 160mg/dl, triglyc 107mg/dl, HDL 60mg/dl, VLDL 21mg/dl, LDL 79mg/dl). However, I have been having a hard time finding low GI foods/snacks that will let me life within a 1600 cal/day diet to maintain sufficient cal deficit for weight loss of ~1-1.5 lbs/week.

    Here is the smoothie I have been making, not for breakfast, but rather for post-gym recovery and "dinner-dimmer" to avoid binging.

    1/4c frozen blueberries

    1c unsweetened vanilla almond milk

    1t ground chia seeds

    1t glutamine

    1sc whey protein powder (Jillien Michel's)

    1/2 banana

    1-2c spinach



    Fairly satisfying and pretty yummy!

    Dr Davis
    How can peanut butter be good.
    Think about the lectins.

    "The far bigger concern, however, is that peanuts contain lectins which are believed to have inflammatory and atherogenic potential.  Most plants contain lectins, some of which are toxic, inflammatory, or both. Many of these lectins are resistant to cooking and to digestive enzymes, and some have been scientifically shown to have significant GI toxicity in humans. Lectins from grains (especially wheat) and legumes (including peanuts and soybeans) are most commonly associated with aggravation of inflammatory and digestive diseases in the body. (As an aside, dairy from cows fed grain-based diets can also contain these grain-derived lectins.)

    Recent research by Dr. Cordain has suggested that these lectins may effectively serve as a “Trojan horse” allowing foreign proteins to invade our natural gut defenses. Cordain reports, “An experiment conducted by Dr. Wang and colleagues and published in the prestigious medical journal Lancet revealed that PNA got into the bloodstream intact in as little 1-4 hours after subjects ate a handful of roasted, salted peanuts.” (Unfortunately, the abstract of this study is not available without a subscription.) The lectins can cause damage well beyond the gut – commonly in joints, brain, and skin of affected individuals. Continued exposure of the gut by these toxins leads to a persistent stimulation of the body’s defense mechanism in a dysfunctional manner, i.e. autoimmune disease. (Allergies fall into that category as well.)" from Dr Loren Cordains Paleo Diet

    I always use home made kefir fermented 24 to 48 hours room temp and another few days in fridge to get rid of almost all the sugar.  My favorite smoothie:
    12 oz kefir (from raw milk)
    1 egg (yes raw but only from one local farmer)
    1 1/2 tablespoonsful cocoa powder
    1/2 avocado when I have
    1/2 tsp glucomannan powder
    and whatever else I feel like throwing in including left over veggies.
    Because my kefir is so sour, I do use stevia to sweeten.

    I hope you don't mind if I take issue with a few things:  Lots of recent information on artificial sweeteners increasing risk of heart attack and stroke.  There are lots of other problems with sucralose and aspartame too.  Peanuts are virtually all contaminated with a mold toxin called aflatoxin and should be avoided.  Extra light olive oil has been heavily processed, often with chemicals and is more toxic than healthy.  I'm hoping you meant extra virgin olive oil?

    One odd comment by Dr. Davis seems to be the low amount of blueberries.

    Most berries don't contain that much fructose, and blueberries (anthocyanins) have health benefits on their own. Even for lipid numbers --
    http://inhumanexperiment.blogspot.com/2009/08/anthocyanins-from-berries-increase-hdl.html


    I don't think 5g of sugar from half a cup of berries will put someone over the edge, if taken with fiber and/or protein. I have also read that blueberries will actually lower one's serum glucose levels.

    And did you mean extra-virgin olive oil?

    Ari--

    While there are individual differences, 8-10 blueberries will just stay below the threshold of most people's tolerance before boosting blood glucose. (It can vary, depending on what else you eat with it, time of day, your weight and state of insulin sensitivity, etc.)

    I prefer stevia. Xylitol and erythritol are other excellent choices, provided you watch out for appetite stimulation.

    Comments about peanuts--

    I know of those data. I'm just not sure about how genuine those concerns are.

    While I love Cordain's work and I have read the few studies on this question, I am not convinced that anything but habitual and substantial exposure has any adverse effect. In other words, if I have a tablespoon of peanut butter once or twice a week, does that really have adverse effects?

    There are indeed foods that can exert undesirable health effects in such small doses. I'm not convinced that peanuts are among them.

    Dr Davis once mentioned that a level handful of berries is all you can eat in one day. I still love my cup of dark berries (from a Three Berries bag from Costco) every night on top of the handful, which I eat with almond milk and flaxseed in the morning. Given that I don't eat other carbs or dairy, I wonder whether this is why my Hemo A1c is now 5.7, which is high for a non-diabetic.

    Doc,
    Is heavy cream a good ingredient for a smoothie?  Being unable to find any coconut milk with kosher certification, I figured that heavy cream sounded tasty.

    I figured if it's milk fat rather than lactose, the insulin increase might be small.

    Insulinotropic Properties of Dairy Protein.


    Milk consumption modifies the insulinemic and glycemic response to carbohydrate-rich food in both type II diabetic and healthy subjects [42]. A population-based prospective study (CARDIA) revealed that dairy consumption was inversely associated with the incidence of all components of the insulin resistance syndrome (IRS) among overweight individuals (BMI>=25kg/m2). Each daily occasion of dairy consumption was associated with 21% lower odds of IRS. These associations were similar for blacks and whites and for men and women [43]. Of the milk proteins, whey leads to higher pre-meal insulin concentrations than casein [44] and may contain the predominant insulin secretagogue because the insulin area under the curve (AUC) after preloads of 25 g carbohydrate with 18.2 g of whey protein was 50% higher than after milk or cheese [42]. Addition of whey to a meal containing rapidly digested and absorbed carbohydrates, stimulated greater plasma insulin concentrations (+57% after lunch) and reduced postprandial blood glucose (–21% at 120 min AUC) in type II diabetic subjects [45]. Amino acids may be the primary factor accounting for the insulinotropic effect of whey protein. Healthy subjects that ingested mixture of leucine, isoleucine, valine,lysine and threonine resulted in glycemic and insulinemic responses similar to those after whey ingestion [46] suggesting that branched-chain amino acids (BCAAs) are the major determinants of insulinemia as well as lowered glycemia caused by the whey drink. However the BCAA mixture did not stimulate incretin (GIP and GLP-1) response while the whey drink did suggesting that the action of whey is not simply related to amino acid content and presumably due to the action of peptides. The authors concluded that whey-induced hyperinsulinemia occurs by two or even more separate pathways, one connected to the significant increment in certain amino acids but the other connected through the incretins, which are believed to interact with bioactive peptides derived from proteins [46].

    1- yes, milk increases insulin production, confirming the blog starting premise
    BUT
    2- opposing the blog unproven conclusion that does NOT lead to diabetes, on the contrary:

    A population-based prospective study (CARDIA) revealed that dairy consumption was inversely associated with the incidence of all components of the insulin resistance syndrome (IRS) among overweight individuals (BMI>=25kg/m2).

    Hi Annonymous,
    I am following your comments here and from an earlier posting I believe. Well, am trying to organize some ideas; basicly thinking out loud here. At this point I am not dealing with the diabetic individual's response or diabetic case management.

    Some comparative charts I've seen tracking levels of both insulin and blood glucose simultaneously over a few hours come to mind. The initial "spike" in insulin was followed by lesser "flush" of insulin many (not a few, nor several) minutes later, and again a mini "blip" or two  farther along in time. While the blood glucose, for it's part, did not follow a linear rise and linear decline either.

    If my memory serves the two factors (insulin increases and blood sugar waves)did not coincide in a proportionate overlay pattern . There was an initial relationship seemingly involving insulin and blood sugar showing up to be seen, as we expect in first meal of the day.

    Bloggers seem to propose the  hormone insulin activates in response to blood sugar, "drives" (or tries to drive) glucose into cells and then both go back to discrete levels (if there is no metabolic syndrome). In other words it's unexplicitly
    represented as a one step, two step, bow out until next time eat and go back to some baseline.

    Studies charting one and not the other give an incongruous picture; the two (insulin and blood glucose) don't seem to dance just with respect to each other. I think this is what you found with the insulin raising properties of dairy/whey having an inverse (reducing) effect in living humans of insulin resistance.

    If you have any insight into the signaling role of the hormone insulin I'd like to hear it. Maybe you'd post it back over on the recent thread where Doc showed the insulin response chart. The topic here is "smoothies".

    You are right about the misplacememt of my earlier posts - they are not about smoothies but whether dairy is bad or good, the topic of the previous blog.  I've reposted there as well, but here is the summary:

    According to research (CARDIA cited above), and regardless of insulin/glucose curves,  DAIRY LOWERS YOUR RISK OF DIABETES.  The more daily servings, the lower the risk.

    If you disagree please present support information. This matters to us all who read this type of blog and care for what we eat.

  • Might-o'chondri-AL

    3/22/2011 2:50:50 AM |

    Again Annon.,
    My thinking is that the factor in dairy responsible for what your study found is Insulin-like Growth Factor (IGF); not insulin.
    IGF, a hormone acting protein, has hypo-glycaemin effect; it lowers blood sugar. IGF also improves kidney function, engenders nitrogen balance and decreases cholesterol.

    IGF I & II are found in cow's milk, but not in whey. The % of IGF content varies with phase of lactation the cow is experiencing.

    IGF I in human milk ranges from 1.5 to 19.0 ng/mL -1; at different post natal stages. IGF II in human milk ranges from 2.7 to 35.0 ng/mL -1; at different post natal stages.

    IGF I in cow milk ranges from 2.0to 101.0 ng/mL -1; while IGF II
    ranges from 2.0 to107.0 ng/mL -1 at different lactation stages. So my suggestion is to look at dairy's IGF to explain the benefit you allude to.

    IGF BP2 (insulin-like growth factor binding protein 2) is an
    "anti-diabetic" protein; and when upregulated it modulates any acute hypo-glycemic
    action of IGF.

    I post this here because your last post on "insulin secretagogue" was brief.

    I'm late to the party, but I want to offer (as others have) that ripe avocados make for an incredible smoothie ingredient.  I recently made one comprised of the following simple ingredients: ice, avocado, heavy cream, sugar-free Torani syrup (vanilla).  It was spectacular, and I'm sure that it is easy to adapt and vary it according to personal tastes.

    Some practical info... if you put melted coconut oil in  smoothie, then add a bunch of cold ingredients, you wind up with chunks of frozen coconut oil all over the place.

    Instead, add the melted coconut oil to a pastured egg and blend to emulsify.  Now when you add the berries or peaches and milk and such, the coconut oil will stay smooth within your smoothie, which is supposed to be a SMOOTHIE, not a CHUNKY.  ;)

    My favorite ingredients besides eggs and coconut oil (which are the basis of all my smoothies, having given up on all protein powders in favor of pastured eggs) are leftover cold coffee, cocoa, raw milk, cream, frozen blueberries (1/2 cup), frozen other berries (full cup), shredded dried coconut, nut butters, stevia to taste - not all at once.  Sometimes, I like a mocha/coffee smoothie, sometimes a fruit smoothie, sometimes a nut butter/chocolate smoothie (can do a "nutella" flavored one or an "almond joy" flavored one).  

    Sometimes, I change the flavors up with DaVinci sugarfree syrups, but honestly, I don't consider that "health food".  I've never noticed a reaction to sucralose, but feel it is generally safer to use stevia if one has bg issues, and small amounts of maple syrup or molasses if one does not (they taste too strong to overdo like white sugar).

The notion of genetic modification of foods and livestock is a contentious issue. The purposeful insertion or deletion of a gene into a plant or animal's genome to yield specific traits, such as herbicide resistance, nutritional composition, or size, prompted the Codex Alimentarius Commission, an international effort to regulate the safety of foods, to issue guidelines concerning genetically-modified foods.

The committee is aware of the concept of unintended effects, i.e., effects that were not part of the original gene insertion or deletion design. In their report, last updated in 2009, they state that:

Unintended effects can result from the random insertion of DNA sequences into the plant genome, which may cause disruption or silencing of existing genes, activation of silent genes, or modifications in the expression of existing genes. Unintended effects may also result in the formation of new or changed patterns of metabolites. For example, the expression of enzymes at high levels may give rise to secondary biochemical effects or changes in the regulation of metabolic pathways and/or altered levels of metabolites.

They make the point that food crops generated using techniques without genetic modification are released into the food supply without safety testing:

New varieties of corn, soybean, potatoes and other common food plants are evaluated by breeders for agronomic and phenotypic characteristics, but generally, foods derived from such new plant varieties are not subjected to the rigorous and extensive food safety testing procedures, including studies in animals, that are typical of chemicals, such as food additives or pesticide residues, that may be present in food.

In other words, conventional plant breeding techniques, such as hybridization, backcrossing, and introgression, practices that include crossing parental plants with their progeny over and over again or crossing a plant with an unrelated plant, yield unique plants that are not subject to any regulation. This means that unintended effects that arise are often not identified or tested. Plant geneticists know that, when one plant is crossed with another, approximately 5% of the genes in the offspring are unique to that plant and not present in either parent. It means that offspring may express new characteristics, such as unique gliadin or gluten proteins in wheat, not expressed in either parent and with new immunological potential in consuming humans.

Dr. James Maryanski, the FDA's Biotechnology Coordinator, stated during Congressional testimony in 1999 that:

The new gene splicing techniques are being used to achieve many of the same goals and improvements that plant breeders have sought through conventional methods. Today's techniques are different from their predecessors in two significant ways. First, they can be used with greater precision and allow for more complete characterization and, therefore, greater predictability about the qualities of the new variety. These techniques give scientists the ability to isolate genes and to introduce new traits into foods without simultaneously introducing many other undesirable traits, as may occur with traditional breeding. [Emphasis mine.]

Efforts by the Codex Alimentarius and FDA are meant to control the introduction and specify safety testing procedures for genetically modified foods. But both organizations have publicly stated that there is another larger problem that has not been addressed that predates genetic modification. In other words, conventional methods like hybridization techniques, the crossing of different strains of a crop or crossing two dissimilar plants (e.g., wheat with a wild grass) have been practiced for decades before genetic modification became possible. And it is still going on.

In other words, the potential hazards of hybridization, often taken to extremes, have essentially been ignored. Hybridized plants are introduced into the food supply with no question of human safety. While hybridization can yield what appear to be benign foods, such as the tangelo, a hybrid of tangerines and grapefruit, it can also yield plants containing extensive unintended effects. It means that unique immunological sequences can be generated. It might be a unique gliadin sequence in wheat or a unique lectin sequence in beans. None are tested prior to selling to humans. So the world frets over the potential dangers of genetic modification while, all along, the much larger hazard of hybridization techniques have been--and still are--going on.

Imagine we applied the hybridization techniques applied by plant geneticists to humans, mating an uncle with his niece, then having the uncle mate again with the offspring, repeating it over and over until some trait was fully expressed. Such extensive inbreeding was practiced in the 19th century German village of Dilsberg, what Mark Twain described as "a thriving and diligent idiot factory."

    Metabolite screening should be done to compare with old standard and apparently is being done to some extent; there will always be someone who reacts adversely to what is innocuous to most people.  Since field agriculture is not free of  problems there will always be need for adaptations.

    Japanese daikon root pickle made today has a different degree of physiological benefit  than when made with a traditional old cultivar of smaller sized daikon.  Hinze's rats might have found old fashioned fare more appetizing but they don't have to struggle to produce it like hungry people worldwide must try to do.

    It's astounding that tests are not done -- are not mandated by law and international treaty -- on hybridized plants prior to the plants being sold for human consumption! One doesn't need to be a bio-chemist to see the danger there.  Of course, I have to wonder what kind of tests should be required.  Some dangers may not be readily apparent.  It could take a human generation or two for the problems to be recognized.  We are lab rats!

    I'm surprised to see stuff about hybrid and GMO plants here.  

    I was an avid gardener before I became disabled and very gung-ho about using open-pollinated seeds, mostly heirlooms.   Even though I didn't save seed, I only bought open-pollinated seeds and plants in order to encourage their preservation by seed companies.  No F1 seeds for me, and DEFINITELY no GMO.  

    When you look into the history even a little bit, you realize even the so-called heirlooms are all pretty new plants.  

    It's been a very short period of time that sweet corn has even existed - corn was always a grain, not a vegetable.  

    Similarly, tomatoes used to be much more acidic than modern varieties are.  It used to be safe to can tomatoes in a hot-water bath.  But new tomatoes need to be canned in a pressure canner... or you have to add acid to the recipe to safely do the water-bath thing and avoid botulism.

    Also, most people have no idea how much yummier heirlooms are.  Vegetables for factory farming have been bred for things like uniform harvest by machinery, ability to keep in storage, not bruising when shipped across country, etc.  Not for TASTE.  

    A Brandywine tomato (my favorite heirloom) tastes NOTHING like what you can buy in a grocery store - because when individuals were doing the breeding, taste was a factor as opposed to  ease of machine harvest and transport and long-term storage.

    You can get good seeds from companies that have taken the No-GMO pledge... such as Baker's Creek Heirloom Seeds, Bountiful Gardens, Southern Exposure Seed Exchange, Pinetree Garden Seeds and Seed Savers Exchange.

    The largest problem is with corn.  Monsanto corn has a gene that makes the plant resistant to Round-up, their primary pesticide.  Even farmers who intend to raise heirlooms have found their fields pollinated by neighbor's Monsanto corn - and been sued since the gene is patented.  

    Farmers that raise heirloom seeds have to raise corn in very isolated spots, and good seed companies test each batch of seed to make sure it's not been infected by the GMO gene.

    Almost ALL corn available today is not only not open-pollinated, but not even normal hybrid corn; rather most of it is GMO.  There's a very few sources of things like non-GMO cornmeal and almost no sweet corn.  

    Same with soybeans - it's all pretty much GMO.  

    IMO, very good reasons to avoid these products in the diet.  I keep a small batch of non-GMO  cornstarch and non-GMO tamari for cooking purposes, but we eat very little corn or soy - and absolutely none of their oils.  Even the non-GMO stuff, corn is very carby, soy causes thyroid issues, and their oils are full of PUFAs. But the small amounts we use in our diet are absolutely non-GMO.

    I forget if it's been released yet or not, but there's a GMO alfalfa coming down the pike.  If the gene is as invasive as the corn gene is, soon it'll be hard to find pasture-raised meat and dairy that hasn't been raised on GMO feed.  

    The largest problem worldwide is in poor countries, where farmers traditionally saved seed to plant again the next year.  These folks literally cannot afford to buy seeds every year.  When all that is available is patented seed or hybrid seed, they are screwed in terms of being able to raise their own food.  People literally starve due to the geopolitics of GMO seed.

    Read up on Monsanto.  They're pretty damned evil.  Probably responsible for more infant deaths than even Nestle.  I personally won't buy products from any company that sells Monsanto products; it's really THAT bad.

    Well, I shall stop my rant now.  I've been ranting about this since back when I was in grad school doing recombinant DNA work myself... I'm getting bored with myself.  ;)

    Thanks for the detailed commentary, jpatti. Exceptionally well said.

    A return to the simplest forms of farming and plant selection are, I agree, are about the only ways to dodge all the genetic shenanigans provided by agribusiness. Scary stuff.

    Thank you! for stating a musing I have expressed for years! Plant breeding starting with Mendel has probably done a whole lot more than soem obscure snippet of gene insertion....not being a proponet here but I agree that a much larger point is missed......but this theme seems to run in a lot of directions in the health world like worrying about "SmartMeters" and their radiation when that cell phone, cordless phone and wireless signals are right there in their face......or how African-American kids in urban environments are asthmatic and all the potential causes make the news  EXCEPT that the notion that that high carb diet they most likely are eating is the main trigger......ditto for all the suffering this population group has later in life.....

    thanks for reviving this Mark Twain quote... to book end it  perhaps reviving Parkinson's Law would be appropriate.

Heart attack guaranteed

Heart attack guaranteed

What if you knew for a fact that your risk for heart attack was 100% by, say, age 58? This is indeed true for many people, though at age 60, 65, 70--or 45.

In other words, unless something were done about the causes of heart disease, you would inevitably suffer a heart attack at 58.

What sort of action could you take at age 45?

Obviously, not smoking is an absolute requirement. Continue and you may as well start getting your affairs together.

How about exercising and eating a generally healthy diet? Will your risk be reduced to zero? No. It might be reduced 20-30%, depending on genetic factors.

How about a statin drug? Watch TV ads during Oprah, and you might think it's a cure. But in reality, while it is a financial bonanza for the drug manufacturers, it will reduce risk for heart attack by 30%.

(Note that risk reduction by following multiple strategies is not necessarily additive. In other words, if you have a healthy lifestyle and take a statin agent, is risk reduced 60% (30 + 30)? No, because the effects may overlap.)

So, eating healthy, exercising, and taking a statin drug might reduce risk 35-40%, maybe 50% in the best case scenario. Would you be satisfied? Most would not.

Add fish oil at a truly therapeutic dose. Risk reduction by itself: 28%.

Add niacin or other strategies for correction of your individual, specific causes of heart disease: Now we're up to 90% reduction.

Throw in a tracking process to prove whether or not atherosclerotic plaque has progressed or reversed. Now we're approaching 100% if plaque reverses. The only way I know how to track plaque is through CT heart scans. What other test is readily available to you with low radiation exposure, yet is relatively inexpensive and precise? It certainly is not stress testing, heart catheterization, CT angiograms, or other techniques. Cholesterol won't tell you. Besides CT heart scans, there's nothing else I know of.

Let's fact it: For many people, uncorrected risk for heart attack is truly 100% at some age. Take action while you can.

That, in a nutshell, is the Track Your Plaque program.
