Vol. 159 December 1, 2016 Dementia Is Going Down, Weight Will Go Up

December 1, 2016

Hub thumbnail 2015

The incidence (number of new cases per year) of dementia in the U.S. is apparently declining.

The Framingham Heart Study which has been monitoring 5,200 adults and 5,000 of their off spring since 1975 revealed in February 2016 that the decrease in the rate of new dementia cases was about 20% per decade. The FHS statistics are based on a variety of data sources including questionnaires, medical records, and some direct examinations.

A more recently published study using direct testing of a larger (21,000), more diverse, over 65 year old (average age: 75) U.S. population reveals that the incidence of dementia decreased from 11.6% in 2000 to 8.8% in 2012. In case you want to “study up” for your test, it included:
recalling 10 nouns immediately and then a little later
serially subtracting 7 from 100
counting backwards from 20

Those with more years of education had a lower risk of dementia. (better “test takers” obviously).
Diabetes increased the risk for developing dementia by 39%. Ominously the incidence of diabetes in this studied population increased greatly from 9% in 1990 to 21% in 2012. Despite that, the overall incidence of dementia did decrease. Nobody knows why.

The Framingham Heart Study findings showed that obesity increased the risk of dementia. In this study obese people had a 30% lower risk for dementia, and in fact, underweight people had a 2.5 fold increase in their risk!

As Dr. Denis Evans, one of the study’s authors, said, “Its very complex.”

Speaking of obesity, the holiday eating season is upon us. Almost all of us expect to put on a little weight. Three scientists from three different countries (Finland, France, and U.S.) nicely graphed the average weight gains by month in three countries (Japan, Germany, and U.S.). No surprise. The Christmas season was the winner in all three countries, but Germany was the leader.

That Golden Week spike in Japan at the end of April and first week of May is when 5 of the 9 official Japanese holidays are clustered and most people take the whole week off.  (NEJM 375:12 Sept. 22, 2016, p. 1201)

Though the graph is impressive with its spikes and valleys the average weight gain in the U.S. measured in the 10 days after Christmas was only 0.7% or 1.33 pounds; much, much less than the 7-13 pound gains per week or two reported by some cruise ship travelers.

The bad news is that even though half of your holiday weight gain is lost shortly after the holidays, half of the weight gain remains until the summer … and beyond, which resets your baseline weight for the next year.
Oh, well. “Life is short. Have dessert first.”

Vol.138 December 15, 2015 Who Buys Baby Parts?

December 15, 2015

Hub thumbnail 2015

The Colorado gunman who shot and killed three people at a Planned Parenthood clinic in Colorado Springs is reported to have said “no more baby parts.”

 

The distorted flap about Planned Parenthood “selling baby parts” continues. On December 3 the Senate ( Republican-led) voted to strip Planned Parenthood (PP) of government funding. President Obama (a Democrat) will veto it if it reaches his desk. (I’m not suggesting that this is a political issue, of course) Planned Parenthood received $528 million from the U.S. government in 2014 to help support 700 clinics providing health services to mostly poor women. Why so much money? Basically because PP is providing subsidized women’s health services that in every other developed country except ours is provided by the government. The Congressional Budget Office estimates that if Congress were to succeed in blocking Medicaid patients from obtaining care at PP health centers 390,000 women would lose access to preventative health care in the first year alone. (1)

Who wants “baby parts”?

In 2014 NIH funded 164 research projects using fetal tissue with about 0.27% of its total grant money. (2) These projects were researching HIV/AIDS (39%) , eye development and disease (32%), Hepatitis C and other infections, (13%), diabetes (8%), and miscellaneous others including Alzeihmer’s and Parkinson’s. “Fetal tissue is a flexible, less-differentiated tissue … and it is a tool for research that can’t be replicated with adult tissue.” (3) It is different from stem cells, a medical tissue that came under attack back in W. Bush’s administration.

Use of fetal tissue has been legal since 1993 when Congress passed the NIH Revitalization Act which permits the tissue from any type of abortion to be used for fetal tissue research. The law requires complete and detailed informed consent from the woman to donate tissue from the abortion after she has made the decision to have an abortion. The law allows clinics to recover “reasonable payments” ($45-60 per specimen at PP) for providing the tissue to biological-research supply companies. The companies process the tissue and provide it to the researcher for about $800 per specimen. (I wonder if any Republicans have stock in some of those companies).

An estimated 5.8 Billion (yes, a “B”) people have received vaccines made with the two cell lines derived from fetal tissue. (Oh, NO, another red flag! “VACCINES”, “Guns”, “abortions” – all mentioned in the same blog! It’s almost enough to make you believe that there is a government conspiracy to enslave us all.)

“People are talking about fetal tissue, but really what the discussion is about is abortion.” (4) ( Duh!!)   3% of PP services are abortions, done in 1% of the clinics, and in just 2 states. (5) Planned Parenthood leaders have now instructed any PP clinic providing fetal tissue NOT to accept the measly 60 bucks.

Planned Parenthood has experienced 15 smear campaigns in 10 years according to its medical director (5). The current campaign has included:
1) six votes in Congress to restrict woman’s health care,
2) five Congressional committees currently investigating PP,
3) submission of 25,000 pages of documents by PP, and
4) 5 hours of testimony to one committee by its president.

Abortion politics appear to be as complex and almost as emotionally provocative as Presidential election politics, but the outcome of election politics will immediately affect only two women, not hundreds of thousands.

A HOLIDAY DIVIDEND:
Another learned cardiologist has reaffirmed the Hubslist axiom: “Just pick your parents right .” Dr. Lee Goldman, Dean of Columbia School of Medicine, explains that obesity is due to our genes in his new book, “Too Much of a Good Thing: How Four Key Survival Traits Are Now Killing Us.” He thinks that our overreaction to stress and our cravings for sweet, fatty, and salty foods all served us well in the cave man years when we had a life-span of 30 years, but that these “survivor genes” are now mismatched with our environment as we live into the 80’s. Of course, being a modern scientist he knows it is too late to “pick your parents”, so he is placing his hopes on future drug therapies that will turn off or block specific genes. Dr. Goldman says, “Gaining weight doesn’t mean that you are a terrible, non-virtuous person. This is the way you were built.” (6)

So, my holiday (includes New Year’s eve, of course) mantra for me and you is:
“Merry Christmas. Don’t beat yourself up. YOU are NOT in control.”

Vol. 137 December 1, 2015 Holiday Season Eating Advice

December 2, 2015

Hub thumbnail 2015

 

“WHY LISTEN TO SO-CALLED HEALTH ‘EXPERTS’
WHEN THEY ARE ALWAYS CHANGING THEIR MINDS
ABOUT WHAT’S GOOD OR BAD TO EAT?”

With the passing of the Thanksgiving turkey we are officially in the “holiday season”. Weight gain during the 6 week holiday season represents 51% of our annual weight gain which is actually only about a pound or two on average. Much less than the average weight gain during a 7-day ship’s cruise of a pound a day. So, what foods should be avoided in the next 6 weeks?

JUNK FOOD?
Junk Food has been the traditional scapegoat for our increasing obesity. But, what is junk food? Decades ago I remember a very savvy pediatric endocrinologist, Dr. Gilbert Forbes, challenging a forum of physicians at a national pediatric meeting to define junk foods.
“Food high in sugar and carbohydrates”, was our immediate response.
“Like grandma’s apple pie?” was Dr. Forbes’ equally quick reply.
“Oh… high starch foods” was our second try.
“Like potatoes? How come all Germans aren’t fat?”
Our working definition after an hour or more of back and forth boiled down to “anything wrapped in cellophane or delivered by a vending machine.” Dr. Forbes’ point was that it is the total number of calories ingested and not any particular food that contributes to obesity.
Today that definition still holds true

In its inexorable march towards the truth medical science has just thrown a stone at the junk food glass house. A Cornell study (1) based on nearly 5,000 surveys done by the CDC in 2007-2008 surprisingly showed that for 95% of the people their BMI  (a measure of obesity) was NOT linked to soda, fast food, or even candy. The researchers expected to find that the more junk food people ate the more apt they were to be obese. Instead they found no correlation between eating junk food and a higher BMI; no link between junk food and obesity. The researchers concluded that it was our increased intake of grains and added fats that was driving up the number of calories consumed by the average American.  “Junk foods may not be the central difference between fat and thin. Limiting those foods is a part of a healthy diet, but it might not be the whole thing.” (2)

 SUGAR?
Sugar continues to get a bad rap, and we consume more and more sugar substitutes. But, as we say in medical science, “there ain’t no free lunch”. Studies showing that Canadian lab mice were more prone to develop bladder cancer if fed saccharine (Sweet and Low) certainly caused a bit of a flap until someone calculated the comparative human doses to be several shovelfuls a day. Sucralose (Splenda) is now under investigation because its effect on our gut bacteria may make us more prone to gain weight and develop diabetes. Like Fox radio news says, “We report, You decide.”

SALT?
Excess (added) salt does seem to correlate with higher blood pressure.  I don’t have the space here to summarize again the whiplash swings of research on salt and disease, but I can tell another story from the past that makes the point more succinctly.
A bunch of physicians (all male – I told you this was a story from the past) who were having lunch at the same table in a hospital cafeteria started remarking about the prodigious amount of salt a cardiologist was pouring on his food. As the discussion heated up, the cardiologist looked up from his plate and stopped it with a question, “How many of you have talked to your father in the past year.” Half of us raised our hands. “You guys can eat what you want. The others better watch their diets. You just have to pick your parents right.”

EGGS?
After decades of branding eggs as “bad” because of its cholesterol the federal government’s Dietary Guidelines Advisory Committee reported in 2015 that “eggs are OK.” A 1999 Harvard study showed that there was no correlation between an egg a day and the risk of heart disease in healthy people (3). 90% of our cholesterol is manufactured by our own liver as directed by our genes. Restricting our intake of certain fats can normally decrease our cholesterol level by about 10% at most.

WINE or BEER?
Previous studies have shown that wine drinkers seemed to experience less heart disease and certain cancers. Efforts to analyze why wine seemed so healthy resulted in tagging resveratrol, a chemical in grape skin, as the “active ingredient”. Dozens of nutritional supplements containing resveratrol ($12 – $25 for a month’s supply) immediately hit the market. Four Danish scientists thought that answer might be too simple and launched a study of what else those wine drinkers were buying at the food store. After examining 3.5 million store receipt transactions from 98 supermarkets they found that wine drinkers were more apt to buy olives, low-fat cheese, fruits and vegetables, low-fat meat, spices, and tea. Beer drinkers were more likely to buy chips, ketchup, margarine, sugar, ready-cooked meals, soft drinks, and, of course, beer. (4)

BOTTOM LINE for this holiday season?
“PICK YOUR PARENTS RIGHT, AND EAT AND DRINK IN MODERATION.”

Vol. 114 June 1, 2014 Much Ado About Nothing

June 1, 2014

“[In response to] an announcement from another U.S. infant formula manufacturer
about its plans to decrease the caloric density of some of its formula to 19 kcal/fl. oz,
Mead Johnson Nutrition (MUN) would like to assure youthat we have
NO plans to modify the density of our formulas from 20kcal/fl oz to 19 kcal/fl oz.”
-Mead Johnson news bulletin to pediatricians, April 1, 2014

 

My last two blogs discussed the evils of added sugar documented by the movie “Fed Up” and the possibility of an FDA ban of added trans fats in manufactured foods.  Both describe politically correct responses to the growing awareness of U.S. and global obesity rates and prevalence. We are urged to become ingredient list readers and to “buy healthier” as a defense against food corporations’ slick advertising and successful lobbying against transparent ingredient lists.

Abbott is the latest food corporation to claim to save us all from the scourge of infant obesity, all by reducing its Similac calories by  1 kcal/fl. oz.   Mead Johnson’s (Enfamil) rebuttal warns that reducing the formula calories means that infants would need to consume 1.5 more ounces per day to “meet their daily energy requirements during the first six months.”  All my kids have left more than that on their bibs  and chins every day, or as Stephen Colbert might say,  “Give me a f&*king break!”

Abbott’s stated reason for the formula change, already labeled by Abbott as “Innovative”, is to help decrease excessive infant weight gain by matching its formula content more closely to breast milk. In my increasingly skeptical (cynical) view Similac is merely adding new marketing buzz words to the current debate about what makes obese infants and do they become obese adults?

It is hard for me to get too excited about minimal formula calorie changes when I remember that one can of Coke, Pepsi, or Sprite contains more sugar than  100% of the total daily requirement of sugar as defined by the American Heart Association (36 g).  Mayor Bloomberg’s campaign against the super-size soda which contains 128g of sugar and the efforts to remove soda vending machines from schools even make some sense. One kcal/fl oz. or 1.5 more ounces of formula a day certainly pales by comparison on the spectrum of “sublime to ridiculous”.

One of the perks of being a pediatrician is being reminded daily about the flexibility, innate wisdom, and versatility of infants and toddlers. In a two-page  news announcement peppered with scientific journal citations the American Academy of Pediatrics Committee on Nutrition notes that ” the number of formulas choices have increased and the selection process is more complicated”.  It concludes in one of its more common-sense statements that “infants appear to eat to satisfy energy needs and will compensate for low food energy density … by increasing food intake.” Duh? More importantly,  “Neither parents nor pediatricians should assume that newer and more expensive products have health benefits for infants.”


Vol.113 May 15, 2014 More “Bad Stuff” For You

May 15, 2014

“I have a chef who makes sure that I’m getting the right amounts of carbs, proteins and fats
throughout the day to keep me at my max performance level.”
Barry Bonds

My last blog reviewing the movie “FED UP” listed many of the compelling reasons why “added sugar” is bad for you and why food manufacturers keep adding it. Just as I was getting used to looking for the total grams of sugar on processed food labels, some active health food advocates are urging the FDA to declare partially hydrogenated oils (“trans fats”) as bad too. Now I will have to start scanning ingredient lists for that!

These particular “health food advocates” happen to be two scientists from Stanford University and Temple University writing an article in the New England Journal of Medicine (1). This bicoastal duo reports that since 1911 food companies have been adding artificial trans fats to foods to prolong shelf life, improve stability during deep-frying, and enhance taste. Unfortunately, added trans fats alter the balance of good and bad cholesterol in a harmful direction. The CDC estimates that 20,000 coronary events and 7000 deaths per year could be prevented by NOT ADDING trans fats to processed food. Denmark banned it in 2003. New York city banned it in restaurants in 2006, and California did so in 2008.

In 2006 the FDA required food processors to list trans fat as an ingredient, and many manufacturers reduced the amount added to their products to avoid having to declare it as an ingredient. Recently the FDA has proposed a regulation removing trans fats from its “GRAS” category (“Generally Regarded As Safe”) and declaring partially hydrogenated oils (trans fats) as “unsafe” in any food sold in the U.S.

The authors note that “over the past few decades, food-safety concerns have expanded from issues of food borne illness and contamination … to the effects food ingredients have on chronic diseases such as heart disease.” They end their essay optimistically with “regulatory reconsideration of ingredients such as sugar, caffeine, and salt may well be next on the agenda.”

Reeling from this latest disclosure of potentially dangerous things that I unknowingly put into my mouth, I sat back in my recliner with a relaxing glass of red wine only to read in WIRED magazine that wine is not the pure libation that I thought it was! Some of the FDA-approved additives in wine include:

  • sulfur dioxide to kill microbes and prevent oxidation,
  • ammonium salts to revive dying yeast to enhance fermentation,
  • pectic enzymes to improve clarity and color,
  • oak adjuncts (chips, sawdust, or oak “essence”) instead of oak barrel maturing,
  • gum arabic to soften a bitter wine,
  • Velcorin (dimethyl dicarbonate) to kill a half-dozen different bacteria and yeasts,
  • and, of course sugar.

Added sugar  from beet, cane, or corn syrup increases the alcohol content from fermentation. The process is called “Chaptalization”, invented by a Frenchman and illegal in California, Italy, and Australia.

It is simply a wonder that any of us live to be over 65.
I think I’ll just pop open a beer and settle back to read yet another article about how the ills of the elderly are bankrupting our country.
… Or better yet, a martini.
I almost have my physician convinced that gin is “a clear liquid”.

Vol. 112 May 1, 2014 Sugar is Bad! Oh no, Not Again.

May 1, 2014

hub

I say “oh, no, not again” because 30 years ago I spent some time in my practice and in the community
defending “bad” sugar against accusations that it caused hyperactivity and attention deficit syndrome.
Research, then and now, has shown that in only about 25% of hyperactive children
eliminating, not the sugar,but the dyes and other additives in sugary foods can reduce their hyperactivity.

 

The film “FED UP” which I just saw in advance of its general release on May 9 makes a compelling argument that the amount of “unaccompanied” sugar (the American Heart Association calls it “added” sugar) that we eat is causing our obesity epidemic. It is narrated by Katie Couric and produced by the producer of “An Inconvenient Truth”.

The film simplifies complex nutritional and biochemistry processes with an easily understood cartoon diagram showing sugar ingested without accompanying fiber or protein being absorbed quickly, traveling directly to the liver where it ignites a burst of insulin that converts the sugar directly into fat. If fiber or protein is ingested along with the sugar this absorption is slowed, less insulin is released, and less fat tissue results. Hence the campaign against super-size sodas in New York City and efforts to ban soda vending machines from our schools. The film points out how detractors try to reframe the soda discussions into terms of “individual liberty vs. an over-reaching government”, rather than that of a serious health issue.

“FED UP” explicitly demands that we demonize sugar the way we have demonized tobacco. “Both are extreme health hazards”.

The average daily consumption of sugar in the U.S. is 84 grams. The American Heart Association recommends 36 grams a day of added sugar. “Processed food” with its high sugar content gets the black mark here as compared to “real food”, which if it has sugar, also has fiber which delays its immediate conversion into fat. The film’s examples of the success, power, and money of the “sugar lobby” and big food corporations are particularly provocative. The film removes all blame from the fat individual and places it squarely on the persistently clever, seductive advertising (particularly to young children) of food processors and distributors. The film’s revelations of the ability of the food and sugar lobbies to resist truthful, transparent labeling and to continue to outmaneuver an amorphous front of three different federal regulatory agencies is compelling .

Fun facts presented by “FED UP” include:

  • When President Reagan cut the school lunch federal subsidy in the 80’s many schools outsourced lunch preparation to fast food suppliers and closed their school kitchen to lower costs. Today 80% of schools in U.S. have their school lunches provided this way (pizza, french fries, cheeseburgers, and sodas – Pizza Hut, MacDonald’s, etc.) Do you know where your schools get their lunches?
  • Promoting student choice of healthy alternatives is an easy, obvious answer to outsourced vendor lunches, but in a school where a healthy alternative is offered a cafeteria worker reports that “only about 25 out of 350 students actually choose it”.
  • Multiple sugar products are often hidden on ingredient labels by use of unfamiliar names.
  • All the fat taken out of milk and other dairy products during the 1980’s rush toward “fat-free” food has been successfully re-marketed as increased cheese products. Many food manufacturers added even more sugar to restore the taste of “reduced fat” foods.
  • Sugar is the ONLY ingredient on the ingredients list that is NOT accompanied with a “percentage of daily requirement” number. This “% number” has been kept off the labels by the sugar lobby. If it were added, we could quickly see that we often exceed our “daily requirement of sugar” about half way through lunch. The film depicts a bowl of corn flakes as actually a bowl of sugar.

A couple of reservations about the film:
1. The film touches only briefly on the genetic contribution to obesity. It explains the two, clearly thin brothers running around in the background of one of the featured fat families, as TOFI (Thin Outside Fat Inside), a recent concept which depends on specialized total body MRI imaging to identify.

2. Its explanation of why the rest of the world is also getting fat is “that we are so good at exporting our ads and processed food to the rest of the world”. I think that is too weak to explain the rise of obesity in countries like Spain, Switzerland, and Korea.

Internatl obesity rates
“FED UP” closes with some specific recommendations and challenges:

  • Reduce sugar intake by 50% by cooking “real” food.
  • Any food with more than 12 listed ingredients is a processed food not a “real” food.
  • Eat fresh, buy local
  • GO SUGAR FREE FOR 10 DAYS. A difficult thing to do because of all the hidden sugar in soups, sauces, catsup, yogurt, and canned foods. A family in the film did do it for 10 days, liked it, extended it, and lost dozens of pounds.
  • Ask your legislators to pass laws requiring the inclusion of “% of daily requirement” for sugar on all labels, just like all the other listed ingredients.

Dare I close with the tag line that this thoughtful, polemic film provides us (U.S.) with “much food for thought”?
.                                     Look for “FED UP” after May 9.
