Sugar and Moderation
mod-er-a-tion [mod-uh-rey-shuh n]
-noun
1. the quality of being moderate; restraint; avoidance of extremes or excess; temperance.
We already know that sugar can cause tooth decay and periodontal disease, but brushing your teeth after every meal won't keep you safe. The following is a list of some of sugar's metabolic consequences from a variety of medical journals and other scientific publications...
* Sugar can suppress your immune system and impair your defenses against infectious disease.
* Sugar upsets the mineral relationships in your body. Example: Sugar interferes with the body's absorption of calcium and magnesium. Why is this problematic? Calcium maintains healthy bones, supports proper functioning of nerves and muscles, and helps your blood clot. Magnesium relaxes your nerves and muscles, builds and strengthens bones, and keeps your blood circulating smoothly. It is no surprise that sugar can contribute to osteoporosis.
* Sugar can cause a rapid rise of adrenaline, hyperactivity, anxiety, difficulty concentrating, and crankiness in children. Additionally, sugar can reduce the learning capacity, adversely affect school children's grades, and cause learning disorders.
* Sugar can produce a significant rise in total cholesterol, triglycerides and bad cholesterol, and a decrease in good cholesterol.
* Sugar can cause a loss of tissue elasticity and function. Sugar can make your skin age prematurely by changing the structure of collagen.
* Sugar can impair the structure of your DNA. Diets high in sugar will increase free radicals and oxidative stress. Sugar feeds cancer cells and has been connected with the development of cancer of the breast, ovaries, prostate, rectum, pancreas, biliary tract, lung, gallbladder, and stomach.
* Sugar can increase fasting levels of glucose and can cause reactive hypoglycemia. Sugar can cause a decrease in your insulin sensitivity, thereby causing abnormally high insulin levels and eventually diabetes. In oral contraceptive users, sugar can elevate glucose and insulin responses.
* Sugar can weaken eyesight; research shows sugar can cause cataracts and nearsightedness.
* Sugar can cause many problems with the gastrointestinal tract including: an acidic digestive tract; indigestion; malabsorption in patients with functional bowel disease; increased risk of Crohn's disease; ulcerative colitis.
* Sugar contributes to obesity.
* Sugar can cause autoimmune diseases such as arthritis, asthma, and multiple sclerosis. Sugar can cause atherosclerosis and cardiovascular disease. Sugar can increase your risk for diseases such as gout and Alzheimer's. Sugar has the potential of inducing abnnormal metabolic processes in a normal, healthy individual and to promote chronic degenerative diseases.
* Sugar can increase your systolic blood pressure.
* Sugar can interfere with your absorption of protein. Sugar can change the structure of protein and cause a permanent alteration of the way the proteins act in your body. High sugar intake increases advanced glycation end products--sugar molecules that attach to and thereby damage proteins in the body.
* Sugar lowers the ability of enzymes to fucntion.
* Sugar can increase the size of your liver by making your liver cells divide, and it can increase the amount of liver fat.
* Sugar can increase kidney size and produce pathological changes in the kidney such as the formation of kidney stones.
* Sugar can cause an increase in alpha, delta, and theta brain waves. This can alter your mind's ability to think clearly. Sugar can cause depression.
* Sugar can cause hormonal imbalances such as increased estrogen in men, exacerbated PMS in women, and decreased growth hormone.
* Your body changes sugar into 2-5 times more fat in the bloodstream than it does starch.
* The rapid absorption of sugar promotes excessive food intake in obese subjects.
* Sugar can slow the ability of your adrenal glands to function.
* Sugar can damage your pancreas.
* Sugar can increase your body's fluid retention.
* Sugar can compromise the lining of your capillaries.
* Sugar can make your tendons more brittle.
* Sugar can cause headaches and migraines.
* High sugar intake can cause epileptic seizures.
So what should we do about our sugar intake? Look for "no-sugar added" options or products made with stevia. Avoid artificial sweeteners (Splenda, Equal, Sweet & Low), as they have an adverse effect on insulin absorption. If you insist on using sweetener packets, I recommend Sun Crystals, a 5-calorie-per-serving combination of natural stevia and sugar. Switch your granulated white sugar (which is highly refined) for organic, unbleached sugar or unrefined brown sugar (a.k.a. raw sugar) which is slightly purified, crystallized evaporated cane juice. It has a distinctive caramel flavor and comes in varieties such as demerara, dark muscovado, and turbinado. Try unrefined dehydrated cane juice, which is made by extracting and dehydrating cane juice with minimal loss of color, flavor, or nutrients. Other natural sweeteners include pure maple syrup, unsulphured, molasses, barley malt, rice syrup, agave nectar, and honey (please note that darker honeys tend to have a stronger flavor than lighter ones).

Sweet potatoes
According to The World's Healthiest Foods, sweet potatoes "contain unique root storage proteins that have been observed to have significant antioxidant capacities."
Sweet potatoes are an excellent source of vitamin A (438% DV in the form of beta-carotene), a very good source of vitamin C (37% DV) and manganese (28% DV), and a good source of copper (9% DV), dietary fiber (15% DV), vitamin B6 (15% DV), potassium (15% DV), and iron (4%).
Sweet potatoes have healing antioxidant properties thanks to it's high levels of vitamins A and C, which work in the body to eliminate free radicals. Free radicals are chemicals that damage cells and cell membranes and are associated with the development of conditions like atherosclerosis, diabetic heart disease, and colon cancer. Vitamins A and C are anti-inflammatory and therefore helpful in reducing the severity of conditions such as asthma, osteoarthritis, and rheumatoid arthritis.
Did you know the antioxidant activity in sweet potato skin, regardless of its color, is almost three times higher than in the rest of the tissue? Regarding color, sweet potatoes can be white, yellow, orange, red, or purple!
Because they have a significantly lower glycemic index than white potatoes--in fact, the lowest among root vegetables--sweet potatoes are a great replacement for traditional starches such as rice, white potatoes, and pasta.
The nutritionists at the Center for Science in the Public Interest (CSPI) ranked sweet potatoes number one in nutrition of all vegetables due to its dietary fiber, naturally occurring sugars and complex carbohydrates, protein, vitamins A and C, iron, and calcium. Check out the CSPI vegetable rankings here.
So how should you eat them? Try sprinkling a baked sweet potato with cinnamon or turning this nutritious root veggie into baked sweet potato chips or oven fries--delicious, trust me! Personally, I prefer to eat mine baked and plain. Just avoid the sweet potato casseroles full of brown sugar and marshmallows or substitute them with healthier options like Maple-Roasted Sweet Potatoes or a healthier version of sweet potato casserole!

The incredible edible egg!
Eggs are packed with a number of nutrients. One egg has 13 essential vitamins and minerals for only 70 calories and 5 grams of fat. At around just $0.14 each, eggs are an affordable source of high-quality protein including all nine essential amino acids, as well as healthy unsaturated fats. Lutein and zeaxanthin, two antioxidants that contribute to eye health, are also found in eggs.
THIRTEEN ESSENTIAL VITAMINS AND MINERALS
Choline (23% Daily Value): Essential for normal functioning of all cells, including those involved with metabolism, brain and nerve function, memory and the transportation of nutrients throughout the body. Choline also helps prevent birth defects, as well as helps promote brain and memory development in infants.
Selenium (23% Daily Value): Acts as an antioxidant to prevent the breakdown of body tissues. Selenium works hand-in-hand with vitamin E to protect against some chronic diseases.
Riboflavin (14% Daily Value): Helps to produce energy in all the cells of the body.
Vitamin B12 (11% Daily Value): Works to support normal digestion and nerve cell function.
Phosphorus (10% Daily Value): Essential for healthy bones, teeth and cell membranes. Phosphorus is also required for energy production in the body.
Pantothenic Acid (7% Daily Value): Helps breakdown food and assists body cells in producing energy.
Folate (6% Daily Value): Promotes proper fetal development and red blood cell formation.
Iron (5% Daily Value): Plays an important role in red blood cell production and oxygen transport.
Vitamin A (5% Daily Value): Supports growth and maintains healthy skin, vision and immune function.
Vitamin D (5% Daily Value): Works with calcium to strengthen bones and teeth.
Zinc (4% Daily Value): Assists in maintaining immune function, as well as body tissue growth and repair.
Vitamin B6 (3.5% Daily Value): Keeps nerve transmission running smoothly and aids protein in immune function.
Calcium (3% Daily Value): Helps build and maintain strong bones and teeth. This mineral also plays an important role in nerve function, muscle contraction and blood clotting.
TWO MACRONUTRIENTS
Protein (13% Daily Value): Essential for building and repairing body tissue and muscle, and aides in immune function. High-quality protein, like the protein in eggs, may also help people maintain a healthy weight. In fact, recent research shows that eating eggs for breakfast, as part of a reduced-calorie diet, helps overweight adults feel fuller for longer, feel more energetic and lose more weight.
Unsaturated Fats (1.9 grams monounsaturated, 0.68 grams polyunsaturated): Function as insulators and building blocks of hormones and cell membranes. Intake of these unsaturated “heart healthy” fats has been shown to help lower cholesterol levels, particularly when consumed in place of saturated fat.
TWO ANTIOXIDANTS
Lutein & Zeaxanthin (166 micrograms): Contribute to eye health and help prevent common causes of age-related blindness. Both antioxidants are found in the egg yolk and are believed to reduce the risk of developing cataracts and age-related macular degeneration, a disease that develops with age and causes blurred or distorted vision. While eggs contain small amounts of these nutrients, research shows that lutein and zeaxanthin may be more bioavailable from eggs than from richer sources.
PROTEIN AND WEIGHT MANAGEMENT
One egg provides 6 grams of protein... 12% of the Recommended Daily Value! Eggs provide all of the essential amino acids; while many people think the egg white has all the protein, the yolk actually provides nearly half of it.
The high-quality protein in eggs helps you to feel full longer and stay energized, which contributes to maintaining a healthy weight. In fact, research shows that eggs eaten at the start of the day can reduce calorie intake, preventing snacking between meals and keep you satisfied on those busy days when mealtime is delayed.
MUSCLE STRENGTH, REPAIR, AND PRESERVATION
Research indicates that high-quality protein may help active adults build muscle strength and middle-aged and aging adults prevent muscle loss. Consuming eggs following exercise is a great way to get the most benefits from exercise by encouraging muscle tissue repair and growth.
CRACKING THE CHOLESTEROL MYTH
While cardiovascular disease continues to be the number one killer of Americans, many adults are confused about what foods to eat and what to void. A January survey of healthy adults conducted by the Egg Nutrition Center shows that nearly one out of four (24 percent) Americans still avoid eggs for fear of dietary cholesterol, even though 30 ears of research has never linked egg consumption to heart disease. As a result of this myth, many Americans are missing out on the beneficial nutrients of the incredible egg.
A 2007 study of 9,500 people reported in Medical Science Monitor showed that eating one or more eggs a day did not increase the risk of heart disease or stroke among healthy adults, and that eating eggs may be associated with a decrease in blood pressure. Also in 2007, researchers showed that egg consumption contributed less than 1 percent of the risk for heart disease when other risk factors were taken into account. The researchers concluded that broad recommendations to limit egg consumption may be misguided, particularly when eggs' nutritional contributions are considered.
"People should feel secure with the knowledge that the literature shows regular egg consumption does not have a measurable impact on heart disease risk for healthy adults," says Stephen Kritchevsky, Ph.D., director of the J. Paul Sticht Center on Aging at Wake Forest University. "In fact, many countries with high egg consumption are notable for low rates of heart disease.
Not only have decades of research shown no association between egg intake and heart disease risk, but eggs are an excellent source of choline, which plays an important role in breaking down homocysteine, an amino acid in the blood that may be associated with an increased risk of heart disease.

BMR and BMI
To estimate how many calories you should consume in order to maintain your weight, you'll need to do a little math. By using a simple formula called the Harris-Benedict principle, you can assess your basal metabolic rate -- also known as your BMR. (Then, to lose weight, you'll need to cut calories or burn extra calories and shoot for a level lower than the results you get with this formula.)
Your BMR is the amount of energy your body needs to function. We use about 60% of the calories we consume each day for basic bodily functions such as breathing. Other factors that influence your BMR are height, weight, age and sex.
Women = 655 + (4.3 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)
Men = 66 + (6.3 x weight in pounds) + (12.9 x height in inches) - (6.8 x age in years)
Calculate Activity
1. If you are sedentary (little or no exercise): BMR x 1.2
2. If you are lightly active (light exercise 1-3 days/week): BMR x 1.375
3. If you are moderately active (moderate exercise 3-5 days/week): BMR x 1.55
4. If you are very active (hard exercise 6-7 days a week): BMR x 1.725
5. If you are extra active (very hard exercise & physical job or 2x training): BMR x 1.9
Add this number to your BMR. The result of this formula will be the number of calories you can eat every day and maintain your current weight. In order to lose weight, you'll need to take in fewer calories than this result. As you lose weight, you can re-calculate the formula to assess your new BMR.
BODY MASS INDEX
Body Mass Index (BMI) is essentially a ratio of weight to height. It is a reliable indicator for weight categories which may lead to health problems such as diabetes, cancer, and heart disease. The concept of BMI was invented in the 1800's by Belgian polymath Adolphe Quetelet but its popularity can be attributed to a 1972 paper by Ancel Keys which suggested that BMI is the best proxy for body fat percentage compared to height and weight.
Here is a BMI calculator from the CDC.
BMI CATEGORY
< 18.5 : underweight
25.0 – 29.9 : overweight
> 30.0 : obese
