Eating for Two: What’s Good for the Earth is Good for You

Ideas and recipes to improve your own heath and longevity by aligning your diet with what is consistent with Nature, Earth and Human Evolution

Overconsumption of any sugar has deleterious effects on our health.  However, of the primary types of sugars that our cells can utilize; glucose (common in root vegetables and grains), fructose (common in fruit, honey, agave and corn) and galactose (common in legumes and milk) I propose that fructose has the most detrimental effects on human health. Unlike glucose, which is metabolized by most cells as an energy source, fructose is mainly metabolized by liver cells.    As I mentioned in my last post, a study appeared way back in 1988 in the Journal of Diabetes Research and Clinical Practice that showed fructose has a reaction constant 7.5 times higher than glucose as well as a much higher calculated biohazard rating.  Supporting research has increased exponentially since then.

In small amounts AND in the presence of adequate antioxidants, the liver has no problem metabolizing fructose.  In fact, it converts it into glycogen which is the primary fuel for anaerobic muscles (the ones that get really big when you lift weights).  Any fructose left after the muscles have had their fill of glycogen is converted into triglycerides.  These “feed” fat cells for later use.  Depending on which study you read, this occurs if more than 5-7 grams of fructose is consumed in one sitting. In addition to being converted into triglycerides, the excess fructose initiates a damaging, inflammatory response in the liver along with producing elevated levels of free radicals known as reactive oxygen species (ROS).

Here is a brief summary of the amounts of sugar contained in one cup of various fruits and beverages:  Please note that I couldn’t find a breakdown of the glucose to fructose ratio.  Source: http://nutritiondata.self.com/

  • Coke                      (26g sugar) – almost all fructose
  • Bananas               (28g sugar)
  • Apples                 (13g sugar)
  • Apple juice         (24g sugar) – 15 grams of fructose
  • Grapes                 (23g sugar)
  • Apricots               (14g sugar)
  • Cherries               (15g sugar)
  • Grapefruit            (17g sugar)
  • Cantaloupe         (14g sugar)
  • Pears                     (16g sugar)
  • Plums                    (16g sugar)
  • Blueberries         (15g sugar)
  • Blackberries       (7g sugar)
  • Raspberries        (5g sugar)
  • Peaches               (13g sugar)

At first, the inflammation and free radical activity initiated in the liver from fructose results in fat accumulation inside the cells and mildly reduced function. If it continues along this path for any amount of time, a condition called non-alcoholic fatty liver disease, NAFLD, develops.  Scores of studies demonstrate that along with obesity, NAFLD incidence has been steadily rising in Westernized, developed countries and in counties that are becoming developed.   A study showed a 10-year doubling of NAFLD in one Chinese Population and demonstrated that a similar trend was seen in both Korea and Japan.

Note:  I thought it would be interesting to compare fructose consumption and NAFLD incidence in various countries.  I spent several hours and had a research assistant spend several more hours trying to find information on fructose sales or consumption in various countries. The information is very difficult and seemingly expensive to obtain.  If anyone has access to this type of information, please contact me or enjoy the dissertation subject. 

I would like to point out that many of these studies are performed by checking serum levels of the liver enzymes ALT and AST.  The pathological changes occur way before these enzymes levels begin to rise.  According to Dr. Michael Cave, a professor of hepatology, gastroenterology and nutrition at the Univerisity of Louisville, ALT and AST parameters should be much lower because these enzymes only begin to increase long after the inflammation and fat accumulation starts.  To be objective, Dr Cave also presents a strong case for an increase in fatty liver disease as a result of chronic exposures to several persistent organic pollutants  and xenobiotics.  Several studies show that exposing liver cells to fructose, then adding a xenobiotic, results in accelerated inflammation and disease.  It is possible that the rise of fatty liver disease has been a combination of increased fructose intake and exposure to these various environmental pollutants that are now ubiquitous in our environment.

Depending on which study you read, NAFLD is seen in 10-24% of America’s general population and 57-74% of obese individuals.  According to the Mayo Clinic’s website, they describe fatty liver disease as “common and for most people causes no signs, symptoms or complications”.  However, long before any physical symptoms present, the liver’s various functions diminish.  If this continues permanent liver damage occurs along with the cumulative toxicity effects of secondary dysfunction.  In addition, any persistent organic compounds that aren’t removed from the blood by the liver accumulate in fat tissue.

Here is a brief summary of the main functions of the liver:

  • Eliminating endogenous toxins like testosterone and estrogen
  • Eliminating exogenous toxins like gasoline vapors, prescription medications, pesticides, artificial fragrances, hormones from birth control usage that are now in the water supply and BPA from the PVC pipes that carry our water.
  • Generating antioxidants like glutathione which not only carry out Phase 2 detoxification in the liver but neutralize pollutants in the lungs and assist with the recycling of neurotransmitters in the nervous system
  • Metabolizing fat along with various types of cholesterol
  • Generating proteins and enzymes for physiological functions all over the body

It makes me cringe to think what is happening to the livers of those poor souls who become motivated to lose a few extra pounds.  They go running five miles per day, lift weights then drink a bunch of carrot juice or eat a banana because they’ve been misinformed into thinking it’s healthy.  Not only are they putting an extra burden on their liver to metabolize the fat that is being burned, they also have to detoxify the various persistent organic compounds that are released from that fat.  For the final assault they add massive doses of fructose.  It would be really interesting to check the liver enzyme levels on NBC’s “The Biggest Loser” contestants before and during the competition.  If I were them, I would do things to support the poor liver like eating more protein and vegetables, getting rid of the fruit and adding supplements like phosphatidylcholine, folic acid, B6, B12, alpha lipoic acid and N-acetyl cystiene.

Clearly, we evolved with the ability to eat fruit.  For the next post in this series, I will discuss this seeming idiosyncrasy along with how the rise of fructose consumption is causing us to devolve.

This is a continuation from the previous post in which one of my readers asked about methionine restriction as it relates to longevity and methionine content in eggs.  I never claim to be “the knower of the answer” but I like to provide enough information for people to form their own, and perhaps new, ideas.

 As I mentioned last time an increase in metabolism will always result in an elevation of all ROS in cells.  This, by default, speeds cell turnover and aging.  Inversely, reduced metabolism reduces turnover and aging of cells.  This is the same mechanism through which caloric restriction is theorized to promote longevity.   

Restriction of any substance that is severe enough to slow down metabolism causes the mind and body to go into a torpor-like state.  If it doesn’t, damage is incurred.  I see this regularly in my practice as a condition that I have termed “Boulder Syndrome” which I’ve talked about in previous posts.    

It seems that in order to live longer though means of dietary restriction, you have stop fully living or suffer health consequences.  Take SAMe as an example.  SAMe is made from methionine in the liver and acts as the rate limiting step in the production of several neurotransmitters. These include dopamine, serotonin, norepinephrine and its conversion in the brain to epinephrine.  Low levels of these neurotransmitters tend to reduce mental clarity, motivation, drive and overall energy.  This is likely part of the whole conservation mechanism that would naturally slow down the body in times of protein scarcity.

Eggs are so interesting because they contain all the essential nutrients to carry out Phase 1 detoxification and methylation in the liver (choline, methionine, magnesium, B12, B6 and folate).  It happens that a deficiency of any one or more of these essential nutrients has a documented effect on reducing fertility. (Sorry, I just didn’t have time to find that many references for one statement but I can assure you it is a fact).   As I mentioned in the previous post, this could be from some type of signaling from Phase 1 that would indicate the presence of sufficient nutients available for reproduction.  I suspect that if the above nutrients are scarce, Phase 1 probably slows for the purpose of conserving them to maintain other bodily functions more consistent with survival and not reproduction.

Consider how we evolved eating eggs.  In non-tropical zones, eggs are in abundance mainly in the spring and early summer.  As the weather warms the insects hatch providing a sustainable protein source for birds.  The increase in dietary protein, and thus methionine, in birds’ diets would signal the appropriate anabolic processes for them to become fertile and produce eggs.  A few weeks later, early humans would have access to these eggs which would provide the appropriate nutrients for signaling anabolic processes to start preparing them for reproduction.  Methionine moves like a wave through the food chain, from sulfur in soil to plants to insects to birds to humans, signaling the anabolic processes that enable reproduction.

In tropical zones, eggs would have been available most of the time as would an abundance of nutrients that would support reproduction. This scenario applies more to the people of the developed world.

I don’t think simple reduction of dietary methionine intake is sufficient enough to slow aging.  I think it has to be fairly extreme.  Alternatively, I do think that excess amounts of methionine, which would imply excess amounts of protein could be damaging especially if intake of magnesium, folic acid, B12 and B6 is insufficient.  We also have to consider that if we reduce methionine enough to slow down metabolism, caloric consumption must be reduced as well or the slower metabolism will lead to weight gain.

That said, if you would still like to try to reduce your dietary methionine here are some things to consider.  With regards to dietary intake, you have to look at absorption rates. This is influenced by the ratio of methionine to the other amino acids in the protein source.  As a general rule, amino acids will compete with one another for absorption. For example, if you have low levels of threonine, high valine levels inhibit the absorption of methionine  (Anyone want to research which protein sources have these ratios? Good data at http://www.nutritiondata.com/ )  The higher the ratios of other amino acids the lower the absorption will be of methionine.  Animal proteins contain high levels of methionine but much higher ratios of the various other amino acids so ultimately methionine absorption is diminished. I checked some methionine levels in various protein sources and unfortunately got varying results.  It turns out that methionine content of food is related to sulfur content in the soil so there will be significant variability depending on the geography of the food source.  However as a general rule, cottage cheese, eggs and fish were all similar in methionine content. Pork and poultry were a bit higher.  Beef was high but had really high levels of competing amino acids.  Legumes and seeds were much lower.  NOW FOR THE INTERESTING PART.  It has been suggested that a vegan diet offers less methionine and would contribute to longevity through methionine restriction.  However, I found a study done on amino acid absorption in rats.  It turns out that pinto beans, one of the least rich protein sources of methionine, had the highest absorption rate the amino acid.  I’m sure absorption of methionine from soy is low as well because some of the chemicals in soy interfere with overall amino acid absorption.

However, soy introduces an extremely important consideration that might make it impossible for humans to benefit from methionine restriction.  Soy contains estrogen-mimicking phytochemicals which will have some effect on producing anabolic processes. (the exact thing we’re trying to prevent to extend longevity) These chemicals must be detoxified by Phase 1 enzymes in the liver.  If this pathway is not working because of a deficiency of methionine, folic acid etc then there will be accumulation of these chemicals in the fat tissues possibly increasing incidence of hormone-sensitive cancers.  There are hundreds of anabolic hormone-mimicking chemicals that are now ubiquitous in our environment including BPA, several pesticides and hormones from pharmaceutical use. Any steps taken to reduce methionine will slow detoxification of these chemicals to a trickle.

If you want to continue to think creatively, be active, fully participate in life and be able to detoxify various environmental chemicals,  you have no choice but to consume foods that allow your body to do this.  If you want to attempt to extend your life through the means of caloric and methionine restriction then you will spend your life existing, not fully living and you might still get cancer.  Perhaps one way of using the current knowledge of caloric and methionine restriction to extend life is to follow what would naturally happen with the seasons.  For example, reduce your activity in the winter and practice caloric and methionine restriction.  Personally, I love skiing too much and need lots of protein to be able to do it.   That said, I’m going to continue to eat 8-10 eggs per week along with lots of kale.

Beans With Kale, Eggs and Salsa

Since my entry on “Promoting Longevity and Maximizing Telomere Length by Reducing Cell Turnover in Bone with Alkalizing Foods”, I’ve had requests for recipes to achieve this.  I will use the following breakfast recipe to demonstrate not only how to alter your diet to make it more alkalizing but an entire ethos on assembling food to promote longevity.

 Just Add Kale

Any vegetable that can be left in the fridge for weeks and still be in its pristine state is obviously full of antioxidants.  Unlike spinach and chard, kale is very alkalizing.  Being from the cruciferous family, kale is high in indoles.  This phyto-nutrient quells the effects of estrogen and helps to prevent and slow the growth of cancers of the prostate, colon, uterus and breasts.  Their estrogen-quelling effects also make them powerful for reducing the PSA by slowing or reversing prostate growth.  Indoles also help your body neutralize the effects of all those estrogen-like plastic chemicals and pesticides that are ubiquitous in our environment. Being a very hearty plant, it can be grown in harsher climates making it easier to obtain from closer sources thereby reducing its carbon load.  If you have a vegetable garden, kale is easy to grow organically in the cooler seasons.

Tear up two or three kale leaves and add them to any cooked dish or salad to help make your meal more alkalizing and increase your antioxidants.

If you enjoy making fresh vegetable juice, kale is a powerful addition.  Some people find its pungent bitterness objectionable but you only need a leaf or two to get benefits.

Super-Easy Healthy Breakfast Recipe

  • Heat Great Northern beans or Adzuki beans in a little water and add 2-3 leaves of kale torn into bite-sized pieces.  Allow these to steam together until the beans are warm and the kale is lightly steamed to a vibrant green color.  (3-5 minutes)
  • While beans and kale are cooking, add a fresh egg to butter on medium-high heat. (yes, you can eat butter)  When the yolk just begins to whiten, add 1-2 Tbsp of water.  Cover and steam for about 45 seconds depending on how cooked you like your egg.
  • Serve egg on top of beans and kale and add a little sea salt, salsa, and pepper.

Great Northern Beans – Beans are one of the best sources of low-glycemic carbohydrates balanced out with protein.  This balance reduces inflammation throughout the whole body to slow the aging process. It also reduces the survivability of cancer cells.  As I mentioned, pretty much any food that is a protein source is acidifying.  White beans, kidney beans and adzuki beans are all only mildly acidifying so they’re a better choice than animal protein.

Chicken eggs – Little more protein to reduce inflammation and meet one’s minimum daily requirement.  Chicken eggs are only a mildly acidifying protein source BUT it’s important to note that the alkalizing effect comes from the yolk.  The whites are actually acidifying.  In addition to being alkalizing, the egg yolks are one of the few foods that contain a substantial amount of the essential nutrient, phosphatidyl choline, which helps your liver distribute and emulsify fats.  The yolk also contain lots of other fat-soluable vitamins.  It’s also IMPORTANT not to destroy the health-giving nutrients by overcooking the yolk.  If it’s still a little runny all the nutritional benefits are retained.

Sea Salt – a good source of extra minerals and electrolytes makes sea salt incredibly alkalizing.

Salsa or fresh chopped tomato with lime, garlic and cilantro– most of the additional ingredients in salsa, neutralize the acidifying effect of the tomatoes.  In addition, garlic is anti-inflammatory and stimulates the immune system.  Cilantro helps to chelate various heavy metals from the body, especially mercury.
