Nutrition: Fat Intake

www.somclifestyle.com

Information from the USDA  indicates that a diet that includes a high intake of saturated fats, trans fats, and cholesterol increases the risk of unhealthy blood lipid levels which in turn increases the risk of heart disease. A high intake of fat; more than 35%  of calories increases saturated fat intake and makes it more difficult to avoid consuming excess calories which can exacerbate existing issues that occur with obesity and overweight. Most fat sources should be poly or monounsaturated fats. These types of fatty acids are found in fish, nuts, and vegetable oils.

The  USDA recommends that adults consume less than 10% of calories from saturated fatty acids, less than 300mg daily of cholesterol, and keep trans fat consumption as low as possible. Total fat intake should remain between 20-35% of total calories consumed. USDA recommendations for children include a total fat intake between 30-35% of calories consumed for 2-3 year olds; a fat intake of 25-35% of total calories consumed by children and adolescents ages 4 through 18. Most of these fats consumed should be mono and polyunsaturated fat sources.

There are some health benefits of fat. Fat supplies energy and essential fatty acids. Fats also serve as a carrier for the absorption of fat soluble vitamins A, D, E and K as well as cartenoids.  Fats serve as building blocks for membranes and play a key regulatory role in numerous biological functions.

Data from a 1994-1996 study estimated that the average daily intake of trans fats was about 2.6% of total energy intake.  Processed foods and oils provide about 80% of trans fats while only 20% occurs naturally in food from animal sources. Some examples of high saturated fat foods include:  regular (non low fat) milk, cheeses, ground beef (25% fat), whole milk, croissants, frozen desserts, butter, and fried chicken and fish. Foods that include high amounts of trans fats include: cakes, cookies, crackers, pies, bread, animal products, margarine, fried potatoes, potato chips, corn chips, popcorn, and household shortening.

A major contributor to many diet related diseases is the overconsumption of fat. The type and quantity of dietary fats can be risk factors for the development of coronary heart disease and some cancers.  It is estimated that diet related diseases cost society over $250 billion annually in medical expenses and lost productivity.  Dietary Guidelines set in 1990 recommended that total fat consumption should be 30% or less of total caloric intake and saturated fat intake should be limited to less that 10% of total calories consumed.  Most Americans exceed these recommendations on a daily basis, which is a major factor in the quality of their health. 

A USDA study from 1989-91 and 1994-95 that monitored the fat intake of children found that total grams of    fats consumed increased for preschoolers and adolescent males. Adolescent males had the highest levels of fat intake of all the children included in the study: 95g in 1989-91 and 99g in 1994-95. Preschoolers increased their consumption of total grams of fat from 53g in 1989-91 to 55g in 1994-95. The study also indicated that that caloric intake increased in all groups of children included in the study.

A low fat diet reduces the risk for some chronic diseases. Diets that are low in fat and that are rich in fruits and vegetables provide essentials nutrients for the body without exceeding caloric needs.  In addition to fruits and vegetables, foods like POPCAKE pancakes have only 3 grams of fat, 1.5 grams of saturated fat, and no trans fats. Foods like POPCAKE pancakes are an easy way to enjoy low fat foods.

Nutrition: How’s Your Cholesterol?

Thursday, April 15th, 2010

Cholesterol DiagramHigh cholesterol levels are a major risk factor for heart disease.  According to data from the National Cholesterol Education Program; high blood cholesterol levels increase the risk for heart disease and heart attacks. Heart disease is the number one killer of U.S. men and women.  Annually, more than one million Americans have heart attacks and half a million people die from heart disease.

Cholesterol is a fat like substance that builds up in the walls of arteries. When too much has accumulated in the arteries it becomes a condition known as “hardening of the arteries.”  When this occurs, the arteries have become narrowed and blood flow to the heart is slowed down or blocked.  Blood carries oxygen to the heart. If enough blood and oxygen cannot reach the heart the end result is chest pains. A heart attack results when the blood supply to a portion of the heart is completely cut off by a blockage. High cholesterol does not have any symptoms and many Americans are unaware that their cholesterol levels are too high.

Factors that affect cholesterol levels include diet; the saturated fat and cholesterol levels in foods make blood cholesterol levels go up. Weight also affects cholesterol. Being overweight is a risk factor for heart disease and also tends to increase blood cholesterol levels. Physical inactivity is also a risk factor for heart disease. Regular physical activity lowers LDL (low density lipoproteins or “bad” cholesterol) levels and raises HDL (high density lipoproteins or “good” cholesterol) levels. Higher LDL levels increase the chances of developing heart disease or having a heart attack.

Major risk factors that that increase LDL levels include: smoking, high blood pressure, low HDL cholesterol, family history of early heart disease and age.  Conditions like obesity and physical inactivity are also risks for high cholesterol levels.

Cholesterol levels can be lowered to healthy levels by lifestyle changes like a low saturated fat and cholesterol diet and weight management. Both are proven as effective methods of lowering LDL cholesterol levels. In junction with regular exercise, incorporating foods like Popcake pancakes into a low saturated fat and low cholesterol diet is an easy way to reach and maintain healthy cholesterol levels. One serving of three 3.5” pancakes has only 1.5g of saturated fat and just 45mg of cholesterol. Foods like Popcake pancakes help promote good health and healthy bodies.

Nutrition: Sodium Friend or Foe

Thursday, April 15th, 2010

Sodium IntakeSodium is becoming an increasing health problem in the U.S diet and is being linked to various diseases such as hypertension and high blood pressure. According to information from the Mayo Clinic, fast foods as well as processed foods contain extremely high levels of sodium and Americans consume large amounts of fast and processed foods. 77% of the sodium in Americans diets is from fast and processed foods.  There are other sources that add sodium to the American diet: 5% of salt is added while cooking, 6% is added while eating, and 12% is from natural resources. By far, fast and processed foods lead the way as the main source of sodium in the American diet.

Sodium is essential in small amounts and promotes good health.  Sodium helps maintain the proper amount of fluids in the body, helps transmit nerve impulses, and influences the contraction and relaxation of muscles. Kidneys regulate the amount of sodium in your body. When sodium levels are low, the kidneys conserve sodium, when levels are too high; the excess is excreted through urine. If the kidneys are unable to eliminate enough sodium to maintain the proper amount in the body, it begins to accumulate in the blood. Sodium attracts and holds water, which in turn begins to increase the blood volume. Increased blood volume causes the heart to work harder to move blood through the vessels which increases the pressure in the arteries.

According to information from an article from Stephen Daniel, a study from Korea reported that preferences for fast food may enhance preferences for salt which suggests that the globalization of America’s fast food industry is also bringing the health risks associated with fast food along with it.  A report from the Journal of Human Nutrition and Dietetics states that adolescents with the highest intake of fast food also exhibited the highest level of preference for salt. A study from the American Heart Association’s Journal Hypertension found that reducing salt intake form 9.7g to 6.5g daily could reduce blood pressure from 146/91 to 141/88 mmHg within six weeks. This suggests that a minimal amount of salt reduction could promote significant steps toward low blood pressure in a relatively short amount of time. The average daily salt consumption in the West is between 10-12g which exceeds the World Health Organization’s (WHO) recommendation of 5g per day by more than double.

In 2007, an article published in The Lancet Chronic Diseases Series states that reducing salt intake globally by 15% could prevent nearly  9 millions deaths from 2006-2015.  The Annals of Internal Medicine further supports this claim by reporting that reducing American salt consumption by a mere 10% could prevent as many as half a million heart attacks and save the country approximately $32 million in health care costs. Information from the website Healthnews.com states that the reduction of salt intake can promote lower blood pressure levels; a key factor in heart attack and stroke prevention.  This article further supports the theory that cutting a small amount of salt consumption can facilitate large scale positive health outcomes.  The reduction of the amount of salt in processed foods by 9.5% could prevent 531,885 strokes and 480,358 heart attacks in the lifetimes of adults ages 40-85. Additionally, quality adjusted life years would increase by 2.1 million and amount to a total of $32.1billion savings in health care costs.  A decrease of salt consumption of 6% could prevent 327,892 strokes and 306,137 heart attacks while saving nearly $22.4 billion in health care costs and extending quality adjusted life years by 1.3 million.

A  CDC study has found that 75% of Americans consume more than the 2.3g daily recommendation of sodium. This study has also reported that excessive salt consumption contributes to 100,000 U.S. deaths annually. A report found on Healthnews.com has also found a link between salt and sugary drinks like soda. A London study found that children between the ages of 4-18 who ate a high salt diet also drank more sugary soft drinks. It is estimated that if children cut their salt intake by half, which amounts to about an average reduction of 3g daily, a decrease of 2 sugar sweetened soft drinks or an approximate 250 calorie reduction would also occur per week per child.  If the U.S population decreased salt intake by one half teaspoon, the health benefits would be equivalent to a substantial decrease in obesity rates, preventing heart attacks, and reducing smoking rates by 50%.

Numerous studies have indicated that a minimal decrease in salt consumption could have maximum health benefits. Simple things like reducing the amount of fast and processed foods in your diet can drastically reduce the amount of sodium intake and promote good health. Consider foods like Popcake pancakes that are low in sodium and calories and are also 97% fat free. Foods like Popcake pancakes make healthy food choices easy.

U.S. Nutrition 101

Friday, April 2nd, 2010

nutrition-popcake from www.colegacy.orgA recent Reuters report has alarmingly indicated that the level of extreme obesity in children is much higher than previously thought.  This puts U.S children at greater risk of serious health problems as they age. According to the Journal of Pediatrics; a study of more than 700,000 children and teenagers in Southern California found that more than 6% or 45,000 were extremely obese. This same study also indicated that that extreme obesity is rising in almost every group.  7% of boys and 5% of girls are currently classified as extremely obese as are more than 2% of children under five.  If this trend continues and major lifestyle changes do not occur the children in this study and others who are obese can expect a 10-20 year shorter life span and will develop health problems in their 20’s that are generally associated with 40-60 year olds. 

According to pediatrician Amy Porter; this may be the first generation of children who do not outlive their parents. Currently, 1/3 of U.S. children are obese. Obesity and overweight in children is extremely indicative of these health problems being a lifelong issue. 80% of children who are overweight at the ages of 10-15 will be obese by the age of 25. Overweight children account for 25% of obese adults. Adolescents who are overweight are projected to increase the prevalence of obese 35 year olds in 2020 to a range of 30-37% in men and 34-44% in women. Obese children and adolescents are at risk for health factors associated with cardiovascular disease, diabetes, and the increased prevalence of other adult diseases. Sleep apnea is being diagnosed in record numbers in children and teenagers are being referred to orthopedists because of the severity of their knee and joint problems due to excess weight. Type 2 diabetes accounts for 8-45% of new pediatric diabetes cases depending on geography, 2 million adolescents ages 12-19 have pre diabetes, and approximately 176,500 people under the age of 20 have type 2 diabetes. The rate of new cases of type 2 diabetes has doubled in the last decade.

Two thirds of U.S adults are overweight or obese. There are obvious health risks associated with unhealthy body weight such as chronic illnesses like heart disease and diabetes, but more and more studies are indicating the extreme economic impact of obesity. According to a report by Dr. Lesley Russel; chronic illnesses that are directly related to obesity are estimated to add $150 billion annually to U.S health care costs.  Obesity has been linked to a 36% increase in health care spending and more than a quarter of U.S healthcare costs are related to physical inactivity, overweight, and obesity. Exercise and physical activity are obvious solutions to promote health and physical fitness and also combat excess weight and obesity and yet the majority of Americans do not participate in the recommended amount of exercise. A 2003 study reported that more than half; 54.1% of adult Americans failed to meet the recommended guidelines for physical activity.

As obesity rates continue to rise, so do the economic costs straining the country’s already embattled health care system. Dr. Russel also reported that obesity accounts for 7% of Medicare expenditure and 11% of adult Medicaid expenditures. From 1987-2002 private health insurance spending increased from $3.6 billion to an astounding $36.5 billion. This is a more than tenfold increase.   In 2002, spending on medical care related to obesity accounted for 11.6% of all private health care spending. For obese individuals annual medical expenses were $7,235 almost $2,000 more a year than those of a healthy weight who spent $5,390 on annual medical expenses.  Health care spending for obese adults was 56% higher than normal weight adults according to a 2002 study.  Employers of obese workers are also economically impacted. A 2008 study reported that private employers spent approximately $45 billion annually as a result of medical expenses and excessive absenteeism of obese employees.  Obese workers have 183.63 lost work days per 100 full time employees compared to 14.19 lost work days per 100 full time employees of normal weight.

Obese workers have more than twice as many compensation claims as normal weight workers. Children that are treated for obesity are three times more expensive for the healthcare system.  There is also a growing body of evidence that suggests a link between mental health and obesity. Adults who are currently or have been diagnosed with depression are 60% more likely to be obese.  Those with anxiety orders are 30% more likely to be obese and less likely to exercise. Children treated for obesity were also far more likely to be diagnosed with mental health disorders.   There is also an indication that obesity may be a risk factor for Alzheimer’s disease.

Additional information from Dr. Russel’s study had indicated a dramatic increase in U.S obesity rates in the past thirty years. Obesity is associated with approximately 112,000 excess deaths per year in the U.S population in relation to healthy weight individuals.  Even within the past two decades, the obesity rate in the United States has increased exponentially. In 1990, no state had a prevalence of obesity higher than 15% and in ten states the prevalence of obesity was less than 10%. By 2007, only Colorado had a prevalence of obesity less than 20% and thirty states had prevalence equal to or greater than 25%. Three states: Alabama, Mississippi, and Tennessee   had a prevalence of obesity equal to or greater than 30%. A 2008 report indicates that adult obesity rates continue to increase in 37 states and no states show a decline in obesity rates. The rate of combined overweight and obese Americans now exceeds 60% in 32 states and it is predicted that 75% of Americans will be overweight or obese by 2015.

As alarming as these statistics may be, it is still possible to reverse this disturbing trend. The personal choices that people make and teach their children have the greatest impact on their lives and the lives of their family.  Choosing to take a walk or ride a bike for an hour instead of watching television for an hour is a simple and effective choice to preserve good health. Along with regular physical activity, smart food choices also facilitate a healthy body weight and good health. Consider food choices like POPCAKE pancakes as part of a healthy lifestyle. POPCAKE pancakes are 97% fat free, low fat and low sodium and are wonderfully complimented by other healthful foods like fruit. Incorporating these kinds of choices into daily life makes healthy living simple.

Do You Know What You Are Eating?

Health It’s no secret that obesity is a significant problem in the United States affecting adults and children alike. It is important that parents instill good nutritional and exercise habits in their children at a young age. According to the CDC, a study conducted from 1999-2001 has shown that 16% or over 9 million 6-19 year olds are overweight or obese. This number is triple was it was in 1980. The same study also concluded that an additional 15% of the same age group was determined to be at risk of becoming overweight.  In the past three decades obesity has more than doubled in children ages 2-5 and in adolescents ages 12-19. The obesity rates in children ages 6-11 have more than tripled. The study also revealed a correlation between childhood obesity and obesity in adulthood. Obese children, particularly teenagers, were 70% likely to be obese as adults. The detrimental effects of obesity are most readily observed through medical issues, but the consequences are much far more dispersed.

According to the Institute of Medicine, the economic expenditures associated with hospital costs for children and youth for treatment of obesity related illnesses and diseases has increased from $35million from 1979-1981 to $127million form 1991-1997. This figure may seem staggering but considering that diagnoses for type 2 diabetes in children has increased from 4% in the pre 1990’s to 8-45% during the 1990’s it’s not so hard to believe. 60% of obese children between the ages of 5 and 10 have a risk factor for developing heart disease.  25% of this same demographic has at least two risk factors for heart disease including high blood pressure, high cholesterol, and high triglyceride levels.

The United States is unfortunately known as a fast food nation. Because of the prevalence of fast food in most American diets, most American’s sodium levels are far higher that what is deemed healthy.  Most children love fast food and are a staple of many of their diets. According to the National Association of County and City Health Officials; a recent study in the journal Hypertension has shown a statistically significant correlation between salt intake and total fluid intake that generally includes a sugar sweetened soft drink.  The vast majority of fast food kids’ meals include salty French fries and a sugary sweet soda. This not only exacerbates the childhood obesity problem with the calorie, fat, and sugar levels of the meal; this same study has shown that the high sodium content of fast food kids’ meals causes children to crave high content corn syrup drinks. Even those who don’t frequent fast food establishments will still have a hard time minimizing sodium levels in food.  According to nutrition.org, the sodium added to processed foods accounts for 75% of the sodium in U.S diets.

According to the CDC, heart disease is the leading cause of death in the United States for both men and women.  In 2006 631,636 or 26% of Americans died from heart disease. Heart disease is attributed as the cause of more than 1 in 4 deaths.  Annually 785,000 Americans suffer their first heart attack while another 470,000 suffer from their 2nd or 3rd. As if the loss of life statistics weren’t disturbing enough, the price tag associated with the treatment of heart disease in 2010 will cost the nation $316.4 billion. This figure includes the total cost of health care, medications, and lost productivity.  According to the CDC, obesity accounts for 33.9% of the risk factors for heart disease and inactivity accounts for 39.5% of the risks factors for heart disease. According to the Women’s Heart Foundation,  1.5 million heart attacks occur in the U.S annually and 500,000 of these are fatal. 14 million Americans have a medical history of heart attack or angina.  A heart attack occurs about every 20 seconds and a heart attack related death occurs every minute.

Another medical problem that is directly related to obesity is chronic fatigue.  Fatigue and obesity are linked by a medical abnormality known as Insulin Resistance.  Insulin facilitates glucose into cells for energy in a person of healthy body weight. In an obese person, Insulin Resistance desensitizes the cells ‘to insulin and impairs the process.  This results in unbalanced glucose and insulin levels. This imbalance can cause other health risks including diabetes. 50% of Insulin Resistance cases are caused by lifestyle factors and choices. Insulin Resistance and excess weight both cause fatigue- which can increase the fatigue levels in an obese person. According to howstuffworks.com, OHS or Obesity Hyperventilation Syndrome occurs when a significantly obese person does not breathe enough oxygen while sleeping. OHS is believed to result from both a defect in the brain’s control over breathing and excessive weight due to obesity pressing against the chest wall. This pressure against the chest wall makes it difficult for a person to take a deep breath. The shallower breaths result in too much carbon dioxide in the blood and not enough oxygen.  This causes chronic fatigue due to sleep loss, poor sleep quality, and chronic hypoxia or low blood oxygen levels. Morbid obesity is the primary risk factor for OHS.  OHS can also include cardiovascular complications such as hypertension and right heart failure. Left untreated, OHS can cause significant heart and blood vessel complications, severe disability or death.

Sleep and a healthy body weight have a significant relationship, particularly in children. According to the Pediatrics Journal, a recent study has shown a strong correlation between lack of sleep in children and an elevated obesity risk as they grow older. The same study has shown that each additional hour a third grader sleeps at night reduces the risk by 40% that the child will be an obese 6th grader. Irregular bedtimes, caffeine intake, and televisions in children bedrooms are all believed to be contributors to a child’s loss of sleep and obesity. Sleep deprivation is believed to upset the balance between two hormones that regulate appetite: ghrelin; which promotes hunger and leptin; which is a hormone that contributes to the feeling of fullness. The third graders that comprised this study slept an average of 9 hours. Those least likely to be obese slept 10-12 hours consistently.

Parents have the opportunity to instill good nutrition habits in their children at an early age. While U.S. children are bombarded with images of fast foods and unhealthy foods through advertising, parents have a crucial role in showing their children the healthy food alternatives that are far better choices for their health and overall well being.  Food choices like Popcake pancakes are ideal to promote healthy lifestyle choices. Popcake pancakes are low fat, low sodium, and 97% fat free. Popcake pancakes can be used to make countless healthy and delicious breakfasts, lunches, dinners, and snacks.  Parents can feel good about the nutritional value of Popcake pancakes and children will love the taste and the wide variety of meals that can be created.
