Trans Fatty Acids: The poison in our food supply that most people are STILL eating every day

Most people are eating a poison every day without giving it a second thought. This substance can increase belly fat and consuming even small amounts (2% of total energy intake) is consistently linked to coronary heart disease. The research also says that this stuff can increase visceral fat, contribute to insulin resistance, increase risk of type 2 diabetes, increase bad cholesterol, decrease good cholesterol, trigger systemic inflammation and adversely affect almost every cell in your body.
What substance could be so harmful that it causes all of these health problems and yet is so prevalent in our food supply that most people are eating dangerous amounts every single day? This industrially manufactured ingredient is called Trans fatty acids (TFA’s).
TFA’s are not found in nature, with the exception of some ruminant-derived TFA’s in certain dairy products (usually contributing less than 0.5% of total caloric intake). TFA’s come mostly from the industrial hydrogenation of vegetable oils, which alters the natural cis configuration of the oils to the trans configuration. If you see “partially hydrogenated” oil in the ingredients list of any food product, then it contains TFA’s.
TFA’s have been studied for decades, but were largely ignored until the past several years. Research papers linking trans fats to heart disease date back to the 1970’s. In 1994, the Center for Science in the Public Interest petitioned the Food and Drug Administration to put trans fats on food labels (didn’t happen until 2006). Since 2006, TFA’s have thankfully received a decent amount of publicity when they were in the news regarding new food labeling laws and the banning of their use in restaurants in some states.
New studies have been published in the past year confirming the dangers of TFA’s. Four recent studies indicated 24, 20, 27 and 32% higher risk of myocardial infarction (MI) or CHD death for every 2% energy of TFA consumption isocalorically replacing carbohydrate, SFA, cis monounsaturated fatty acids and cis polyunsaturated fatty acids, respectively.
TFA intake in the United States still averages 2-3% of total energy intake, 4% in some developing countries where fast food is being introduced and as high as 8-10% in certain subgroups (who eat large amounts of baked goods, fried foods, pastries, doughnuts, etc). The government recommended maximum is 1% of total energy intake (2 grams!). Some experts say there is NO safe level of TFA intake.
Legislation has been enacted in some states banning the use of TFAs in restaurants. It was big news New York. As of 2008, 11 cities and counties have adopted regulations to restrict TFA use in restaurants. However, industrial TFA use is still widespread and lots of people are still scarfing them down every day.
If Trans fats are so dangerous, why is their use so widespread? Dietary fat expert Udo Erasmus put it this way: “TFA’s are a food manufacturer’s dream: an unspoilable substance that lasts forever.” TFA’s are cheap and for countless food products, they can prolong shelf life, allow easy transport, provide solidity at room temperature (to make spreads), and increase suitability for commercial frying.
Although most people have heard of TFA’s, the bad news is that this increased awareness has not been enough to translate into behavior change.
A study recently published in the Journal of The American Dietetic Association (ADA) found that in 2007, 73% of Americans knew that TFA’s increased risk of heart disease, compared to 63% in 2006. However, the bad news is that 79% of Americans could not name 3 foods that contain trans fats. 46% of Americans could not name any sources of trans fats on their own.
“Knowledge about food sources of fats remains low” says Robert Eckel, professor of Medicine at the University of Colorado.
Public health messages have been raising awareness, but they haven’t been enough. “TFA’s are bad for you.” Ok, so now what? What you really need are some simple behavior guidelines and a list of foods to eat very infrequently if you eat them at all.
Here are some good places for you to start.
4 Ways to Avoid Trans Fatty Acids
1. Eat mostly foods that do not have a label. At the risk of stating the obvious, if you don’t eat anything that comes in a box or package with a label, then you won’t ever consume manmade TFA’s. If your diet consists primarily of fruits, fibrous vegetables, root vegetables, beans, legumes, brown rice, unprocessed whole grains, nuts, seeds, eggs, fish and lean meats, you’re home free.
2. Watch for label loopholes. WARNING: Food companies are lying to you on their product labels to make you think their foods are TFA-free. The front of their package may say “ZERO grams of trans fats,” and yet there is hydrogenated oil listed in the ingredients. How could that be? There is a label loophole where the government allows companies to claim zero trans fats if there is less than a half a gram per serving. So the food companies sneakily manipulate their serving sizes until the servings are so small that the TFA content falls below the per serving limit.
3. Read ingredients lists. The primary source of TFA’s is partially hydrogenated vegetable oils. In particular, soybean, sunflower, cottonseed and palm oils are frequently hydrogenated. Your first step then, is to read food labels on any packaged products and look at the ingredients list. If it contains partially hydrogenated oils, it contains TFA’s.
4. Avoid foods that contain TFA’s most of the time. TFA’s are commonly found in baked goods (bakery), fried foods and packaged convenience foods, especially:
cookies*
crackers*
biscuits*
pastries*
pies*
doughnuts*
packaged frozen foods (breaded chicken, breaded fish, etc)
corn chips
potato chips
packaged popcorn
some breads
frostings
french fries (fried potatoes)
taco shells
margarines and spreads
shortening
some salad dressings
some candies
some artificial cheeses
* major food sources for American adults
In 2002 when I published the first edition of my ebook, Burn The Fat, Feed The Muscle, I warned my readers of the dangers of trans fatty acids. I was not the only one either. Years ahead of the 2006 law requiring trans fats to be listed on food labels and the 2007-2008 restaurant TFA bans, numerous health professionals were already warning people to stay away from TFA’s.
Not enough people heeded the warnings, while meanwhile, politics and commercial interests delayed legislation. No doubt, skyrocketing rates of obesity, diabetes and cardiovascular disease can be largely linked to the continued use of these artificial fake food additives. In the US alone, 1,700,000 new cases of diabetes, 233,600 diabetes-related deaths, 600,000 myocardial infarctions and 451,300 coronary heart disease-related deaths are reported every year.
A campaign for better education and lifestyle change is worth supporting. As researchers from Harvard said, “A comprehensive strategy to eliminate the use of industrial TFA in both developed and developing countries, including education, food labeling, and policy and legislative initiatives, would likely prevent tens of thousands of CHD events worldwide each year.”
For a healthy and balanced lifestyle, and for better long-term compliance, I’m rarely in favor of tagging any foods as totally “forbidden” or to use words as strong as “poison” in describing foods. But if there are any exceptions, trans fats are one of them.
If you are unable or unwilling to eliminate TFA’s from your diet completely, then you would be wise for the sake of your health and your family’s health, to keep foods containing TFA’s to a bare minimum and avoid eating any TFA-laden foods on a daily basis.
Last, but not least, be on guard, because history tells us that when one harmful food additive is banned, it is often replaced with another, which is sometimes even worse. That’s why item #1 on my list of four ways to avoid trans fatty acids is the best way to avoid anything that is harmful to your health.

Calorie Restriction For Life Extension: What They Didn’t Tell You On Oprah
By Tom Venuto
www.brunthefat.com
On a recent episode of the Oprah show, one of the guests was a 51 year old man with the heart of a 20 year old. He’s been following a calorie restriction plan and they said he might be one of the first people to reach 120 years old by following this plan. There have been stories both in the lay press and scientific press about calorie restriction for years and it has been a frequent talk show topic on other many other TV shows. However, before you cut your calories in half in hopes of adding another decade onto your life, you’d better get the other half of the story they didn’t talk about on Oprah.
I’ve seen a lot of strange things in the health field, and although calorie restriction (CR) is the subject of serious and legitimate scientific study, I consider CR to be one of those strange things. Of course, that’s because I choose a different lifestyle – the muscle-friendly Burn The fat, Feed The Muscle lifestyle – but there’s more than one reason why I’m not a CR advocate:
Hunger while dieting is almost always a challenge. There’s some hunger even with conservative calorie deficits of 15-20% under maintenance. Prolonged hunger is one of the biggest reasons people fall off the weight loss diet wagon because it’s unpleasant and difficult to resist. This is why pharmaceutical and supplement companies spend millions of dollars on researching, developing and marketing appetite suppressants. Yet CR advocates put themselves through 30-50% calorie restriction on a daily basis as a way of life in the hopes of extending life span or health.
Practitioners of CR follow a low-calorie lifestyle, but technically, they are not in a chronic 30% calorie deficit. That would be impossible. What happens is their metabolisms get very slow (that’s part of the idea behind CR; if you slow down your metabolism, you allegedly slow down aging). So a 6 foot tall man who would normally require nearly 3,000 calories to maintain his weight, might eventually reach an energy balance at only 1800 or 1900 calories. This is not just due to a ‘starvation mode’ phenomenon, that’s only part of it. It’s primarily because he loses weight until he is very thin and his smaller body doesn’t need many calories any more.
Does caloric restriction really extend lifespan?
The biological mechanisms of lifespan extension through calorie restriction are not fully understood, but researchers say it may involve alterations in energy metabolism (as mentioned above), reduced oxidative damage, improvements in insulin sensitivity, reduction of glycation, modulation of protein metabolism, downregulation of pro-inflammatory genes and functional changes in both neuroendocrine and autonomic nervous systems.
Mouse studies on CR go back as far as 1935 and monkey studies began in the late 1980’s. So far the results are clear on one thing: caloric restriction does increase lifespan in rodents and other lower species (yeast, worms and flies). Studies suggest the life of the laboratory rat is 25% longer with CR (even longer with aggressive CR). Primate studies are still underway and humans have been experimenting with CR for some time. In primates and humans, biomarkers of aging show signs of slower aging with CR. This makes many proponents talk about this CR as if it were a sure-thing, already proven through double-blind randomized clinical human trials.
The truth is, there is NO direct experimental evidence that you will live longer from practicing CR. Due to the length of human lifespans, we will not have the necessary data for at least another generation and perhaps multiple generations. Even then, it will still be highly speculative whether CR will extend human life at all and if so how much. We can only estimate. I’ve seen guesses in the scientific literature ranging from 3 to 13 years, if CR is practiced for an entire adult lifetime.
Jay Phelan, a biologist at UCLA is skeptical. He says the potential life extension is on the lower end of that range and the increase is so small that it’s not worth the semi-starvation:
“There is no current evidence that lifelong caloric restriction leads to increased lifespan in primates. It’s certainly tantalizing that things like blood pressure or heart rate look as though they are a lot healthier and I believe they are. Whether or not this translates to a significantly increased lifespan, I don’t know. I predict that it doesn’t.”
I don’t quibble qualitatively with their results. Yes, it will increase lifespan, but it will not increase it by 50% or 60%, it won’t increase it by 20% or 10%, it might increase it by 2%. So if you tell me that I have to do something horrible for every day of my life for a 2% benefit – for an extra year of life – I say no thanks.”
Is prolonged caloric restriction unhealthy?
When caloric restriction is practiced with optimal nutrition (CRON), it is not inherently unhealthy. Actually, it appears the reverse is true. First, the weight loss that comes with the low calories produces improvements in the health markers, as you would expect. Second, the meticulous choice of food from CRON practitioners, where they pick high nutrient foods and avoid empty calories means that they are making healthy food choices. Third, advocates say that the CR itself improves health. I wonder, however, how much does CR improve health independent of the weight loss and the optimal nutrition?
By losing fat and maintaining an ideal body composition (the fat to muscle ratio) and eating high nutrient density foods, I propose that even at a more normal caloric intake, you will get very significant health and longevity benefits. I also propose that gaining muscle in a natural way (no steroids) will increase your quality of life today and as you get older.
Aside from the fact that we are not lab rats, the truth is, none of us knows when our day will come. We could get plucked off this physical plane at any moment and have no control over how it happens. My belief is that we should make our lifestyle decisions based on quality of life, not just quantity of life. That includes our quality of life today as well as our anticipated quality of life when we are older. Maybe we ought to be focusing more on “health span” than life span.
Downsides of calorie restriction for life extension
One fact about calorie restriction that they often don’t mention on these talk shows is that the benefits of CR decline if you start CR at a later age. This was discussed in a research paper from the Journal of Nutrition called, “Starving for life: what animal studies can and cannot tell us about the use of caloric restriction to prolong human lifespan.” The author of the paper, John Speakman from the School of Biological Sciences at the University of Aberdeen in Scotland, said that the later in life you begin to practice CR, the less of an increase in lifespan you will achieve. Even if the CR proponents are right, if you started in your late 40’s or mid 50’s for example, the benefit would be minimal. If you started in your 60’s the effect would be almost nonexistent. Essentially, you have to “starve for life” to get the benefits.
While some CR proponents claim that they aren’t hungry and they cite studies suggesting that hunger decreases during starvation, Speakman and other researchers say that hunger remains a big problem during CR – especially in today’s modern society where we are surrounded with convenience food and numerous eating cues – and that alone makes CR impractical:
“Neuroendocrine profiles support the idea that animals under CR are continuously hungry. The feasibility of restricting intake in humans for many decades is questionable.”
Let’s suppose for a moment that CR is totally legit and the claims are true. Many of the proposed benefits of CR come at the expense of what many of us are trying to do here: gain and maintain lean body mass. One spokesman for CR is 6 feet tall and 130 pounds. Another poster boy for CR is 6 foot tall and 115 lbs. Measurements of rodents under CR not only show large reductions in skeletal muscle but also bone mass.
I am not suggesting that these CR practitioners are anorexic, a concern that has been raised about CR when practiced aggressively. However, they are losing large amounts of fat-free tissue and that is plainly obvious for all to see when you look at their bony physiques. I am not imposing my body standards on others, but 115 to 130 lbs at 6 foot tall is underweight for a man by any standard. Furthermore, researchers say that at the body mass indices sustained by most voluntary CR practitioners, we would expect females to become amenorrheic. “One thing that is completely incompatible with a CR lifestyle is reproduction” says Speakman.
With that kind of atrophy, I have to wonder what their quality of life will be like in old age. While many people struggle with body fat for most of their adult lives, I’m sure almost everyone knows an elderly person who wrestles with the opposite problem: they are seriously underweight and they struggle to eat enough and maintain lean body mass.
My grandmother, before she passed away, was under 80 lbs. We could not get her to eat. She was weak and very frail. I have reported many times about the research showing how most overweight people under estimate calorie intake and eat more than they think or admit. In elder care homes, the research has often showed the opposite – the patients over estimate how much they eat. They swear they are eating enough, but they arent and they keep losing dangerous amounts of weight. With underweight, atrophied seniors, weakness means less functionality and lower quality of life and a fall can mean more than broken bones, it can be life-threatening.
Life extension with more muscle
While there is a commonality between CRON and the way I recommend eating (high nutrient density, low calorie density foods), in most regards, CR is the opposite of my approach. In my Burn The Fat, Feed The Muscle program, we go for a higher energy flux nutrition program, which means that because we are weight training and doing cardio and leading a very active lifestyle, we get to eat more. Because we are so active and well-trained, the eating more does not have a negative effect as it would on a sedentary person, who might get sick and fat from the additional calories. We active folks take those calories, burn them for energy, partition them into lean muscle tissue and we enjoy a faster metabolism and extremely high quality of life.
As a bodybuilder, CR is not compatible with my priorities, but hypothetically speaking, if I were to practice a lower calorie lifestyle, I wouldn’t follow an aggressive CR approach. I’d probably do as the Okinawans do. They have a very simple philosophy: hari hachi bu: eat until you are only 80% full. While this does not mean there is a carefully measured 20% calorie deficit, it’s consistent with what we practice in the Burn The Fat, Feed The Muscle lifestyle for a fat loss phase, and avoiding overeating is certainly a smart way to avoid obesity and health problems. Incidentally, the Okinawans eat about 40% less than Americans, and 11% less than they should, according to standard caloric intake guidelines, and they live 4 years longer than Americans.
If someone is being “sold” on CR by an enthusiastic CR spokesperson, or simply curious after watching the latest TV talk show (where they are looking for controversial stories), it’s important to know that there is more than one side to the story. If you carefully read the entire body of research on CR, you will see that the experts are split right down the middle in their opinions about whether CR will really work. CR for humans remains highly controversial and there are no guarantees that this will extend your life.
Researchers at the National Institutes of Health in Baltimore, MD put it this way:
“Because it is unlikely that an experimental study will ever be designed to address this question in humans, we respond that “we think we will never know for sure.” We suggest that debate of this question is clearly an academic exercise.”
In closing, let me go back to one of the original questions I was asked: “Can the BFFM food plan also be thought as a longevity lifestyle, but with more muscle mass?” Absolutely beautifully said! That’s precisely what Burn The Fat, Feed The Muscle is.
I believe that by making healthy food choices but doing so at a higher level of calorie intake and expenditure, that we can fend off sarcopenia – the age related decline in muscle mass that debilitates many seniors – while enjoying a more muscular physique, greater strength, and a less restrictive lifestyle. Most gerontologists agree – by making simple lifestyle changes that include strength training and good nutrition, you can easily turn back the biological clock 10 years without going hungry.
