Food Myth 1: Salt is bad for you.
Truth: In 1996, the Journal of the American Medical Association published a meta-analysis of 56 clinical trials done since 1980 in people with normal blood pressure, and found that extreme salt reduction offered little benefit. In addition, recent studies have discussed a growing state of iodine deficiency in the United States, which may be the result of the US government's unsound advice that all Americans avoid eggs and lower salt intake. Worse, there is also evidence that iodine deficiencies contribute to atherosclerosis and heart disease.
Truth: Eggs are a perfect food, providing protein, nutrients and important fatty acids that contribute to the health of the brain and nervous system. The consumption of eggs has been shown to reduce systemic inflammation markers such as C-Reactive Protein, indicating that they have an anti-inflammatory effect.
Truth: People who eat margarine have twice the rate of heart disease as those who eat butter. (Nutrition Week 3/22/91 21:12). The process of making margarine involves several toxic chemicals and specialized equipment. To make butter, you only need a food mixer and a quart of cream. Personally, I prefer the food that is closer to nature. In addition, the scientific evidence, honestly evaluated, does not support the hypothesis that saturated fats cause atherosclerosis or heart disease.
Truth: No scientifically valid study has ever shown a link between saturated fat consumption and heart disease. A recent meta analysis concluded "that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of Coronary Heart Disease or Coronary Vascular Disease."
Throughout the years that heart disease was on the rise in America (1920-1960), the consumption of animal and tropical fats declined, while the consumption of highly inflammatory hydrogenated and refined vegetable oils increased dramatically. This correlates to the now widely accepted theory that unchecked and chronic inflammation is the underlying, unifying cause of heart disease, atherosclerosis, diabetes and a host of other health issues.
Note that the fat in animal products is not all saturated. About 51% of the fat in a steak is monosaturated (like olive oil). About 45% of the fat is saturated fat, but of that, a third is a type of fat called stearic acid, which has been shown to increase the good HDL cholesterol and leave LDL unchanged. The remaining 4% is polyunsaturated fat which has been shown to lower LDL cholesterol. So in summary, 70% of the fat in a steak or in bacon or lard will improve your levels of HDL and LDL cholesterol.
Truth: This editorial in the journal Circulation discusses the fact that the rates of death from all causes are higher in those populations with cholesterol levels lower than 180 mg/dl. This study concluded that "The relative risk of non-cardiac death was 2·27 times higher in the low cholesterol group than in the controls."
Truth: Children need the rich nutrition found in saturated fats to grow and develop normally. It is for this reason that healthy human breast milk is on average about 60% fat.
Truth: Two 1990 studies on red meat found a higher risk of colon cancer among those who eat red meat. However, no study done in Europe has ever shown an association between meat consumption and cancer. This suggests that European sausage and luncheon meat, included in the label of "meat consumption," are prepared by traditional methods that require few additives, while the similar products in the United States contain many carcinogenic preservatives and flavorings. In addition, many other studies have shown that a vegetarian diet, and in particular, refined vegetable oils are more carcinogenic than red meat.
There are several studies that support this hypothesis. In 1975, Rowland Philips compared Seventh-Day Adventists physicians, who do not eat meat, with non-Seventh Day Adventist physicians, and found that the vegetarian doctors had higher rates of gastrointestinal and colon-rectal cancer deaths. National Cancer Institute data show that in Argentina, where high levels of beef are consumed, the rates of colon cancer are significantly lower than other western countries where less beef is consumed.
Red meat from cattle that have been raised humanely is a rich source of nutrients that protect the heart and nervous system including vitamins B12 and B6, zinc, phosphorus, carnitine and Coenzyme Q10, and should be a part of a healthy diet. Just be sure to buy pastured, grass fed meat.
Truth: Cereal grains, in particular wheat and rye, contain many anti-nutrients and natural toxins which are associated with celiac disease and other autoimmune diseases such as rheumatoid arthritis.
In addition, grains, even whole ones, are very high in carbohydrates. There is a huge and growing volume of research which implicates high carb consumption in the epidemics of obesity, diabetes, heart disease and a host of other health problems in the United States.
In the raw state, whole grains are poisonous and cannot be digested by humans, as we don't have 4 stomachs like ruminant animals to break these foods down. They must be processed in some way for human consumption.
Truth: Your body makes more cholesterol on a daily basis than you could ever eat. If you want to lower your cholesterol, you have to eat less carbohydrates, because the body makes cholesterol from sugar (glucose). Any basic biochemistry text will confirm that fact.
Truth: Most modern soy foods are unhealthy foods for humans. Modern soy products are not cooked or fermented properly to neutralize the abundant natural toxins in soybeans, and they are processed in a way that damages the proteins and increases the levels of carcinogens. Read Kaayla Daniel's The Whole Soy Story: The Dark Side of America's Favorite Health Food for more information.
Truth: The Women's Health Initiative Study results, which were published in the Journal of the American Medical Association in 2006, clearly showed that over time, a dietary intervention that reduces total fat intake and increased intakes of vegetables, fruits, and grains does NOT significantly reduce the risk of CHD, stroke, or CVD.
In fact, other studies have shown that when study participants stopped eating fruits and vegetables for a period of 10 weeks, damage to DNA and blood lipids DECREASED. In other words, a diet high in vegetables and fruit increases oxidative damage to cellular DNA.
Truth: The link between a low fat, low cholesterol diet and better health has never been proven by any scientific study. The low fat diet-heart health hypothesis was the outcome of several non-scientific factors driven by aggressive, arrogant personalities and newly financed medical organizations.
The real results of this "low fat is good, eat more grains" advice can be seen in the state of health enjoyed by the average American and the care given to us by our health system.
After following the low fat diet advice given by the American Heart Association and other government agencies for the past 30 years, the United States has one of the highest adult and infant mortality rates of any modern industrialized country.
The skyrocketing rates of diabetes in the US and the rates of chronic disease in general are overwhelming our health care system. The rates of heart disease and cancer have not diminished despite millions of dollars spent on research.
However, the pharmaceutical companies and the medical establishments are doing well financially, as the AHA and other Federal agencies continue to promote the high carb, low fat diet that has caused serious health problems for millions of American citizens.
Truth: Medical schools do not teach nutrition to doctors; they teach doctors how to treat symptoms with drugs. On average, doctors get about 2 weeks of nutritional training. Here's more info about the lack of nutritional training for doctors.
Truth: The modern USDA Food Pyramid is based on principles that have never been proven in any scientific study, and it is heavily influenced by food supply politics, and the food manufacturing and agricultural lobbying. You can read about the history of the USDA Food Pyramid here.
Truth: An essential nutrient is one that must be obtained from the food supply because the human body is unable to make it internally. There are only four essential nutrients needed by the human body to thrive:
Truth: The diet that the American Diabetes Association recommends actually makes diabetics sicker by advocating the consumption of too many carbohydrates. Multiple studies have shown that higher carbohydrate consumption makes diabetic blood sugar control worse, elevates HbA1c levels and worsens blood lipid panel numbers.
