More Food Myths…

Thursday, April 16th, 2009

It seems that everybody enjoyed my top ten food myths so I decided to add to the list.

Pick up any magazine and you will read about the latest diet fad or the next wonder food.  These tips often sound too good to be true because they are not!    Read on to learn the truth about some more food myths.  You will be surprised at what you learn!

11. Fruit juice is healthy

Fruit juice is a source of empty calories. Eating a piece of fruit provides vitamins, fiber and tends to reduce intake of other food. But most fruit juices are just sugary beverages, providing extra calories — all from refined carbohydrates — without sating appetite. And this goes for all juices, from apple and grape juice to acai berry or pomegranate juice.

12. Antioxidant water prevents disease.

Antioxidant water is a marketer’s dream come true because it really sounds like it should be healthy and naturally-occurring antioxidants in other foods have been shown to prevent illness. However, none of the antioxidant waters have shown any health benefits. Antioxidant water is just overpriced water with added sweeteners, flavoring, and supplements. Studies of antioxidant supplements have shown no benefits and their is no reason to believe that the antioxidant supplements in these waters will be any different.

13. Frozen vegetables are less nutritious than fresh ones.

The best time to eat a vegetable is right after it is picked. However, for those of us who do not live on a farm, this is not quite feasible. Nutrient levels drop during shipping and storage. They drop further as the veggies sit in your refrigerator. By the time you eat that fresh vegetable, is has far fewer nutrients and is not quite as fresh. Frozen veggies, on the other hand, are flash-frozen immediately after they are picked so they retain most of their nutrients.

14. Pork is fattening.

It’s true that sausage and ribs are loaded with calories, but three ounces of cooked pork tenderloin has only 140 calories - exactly what you’d find in three ounces of skinless chicken breast. That’s why they call pork “the other white meat”!

15. You should drink eight glasses of water a day.

Studies show that people often mistakenly believe they are hungry when they are simply thirsty. They then eat unneeded calories instead of just drinking a glass of water. A good diet strategy is to make sure you are fully hydrated at all times. However, you do not need to drink eight glasses of water a day to stay fully hydrated. Four glasses of water a day should be sufficient.

16. Trans fat-free foods don’t contain any trans fats

There is a loophole in the FDA’s trans fat labeling law. Any food with less than 1/2 gram of trans fat per serving can be called “trans-fat free.” Manufacturers get to choose what a serving size is, and it rarely matches up with what you want a serving size to be. A cracker company can decide that one small cracker is a serving but if you eat 12 “trans fat-free” crackers, you could have eaten up to 6 grams of trans fat. The key is to look at the ingredient list. If the product contains hydrogenated or partially-hydrogenated oils, it contains trans fats. Since trans fats are so unhealthy, these products should be avoided.

17. Sugar causes behavior problems in kids.

A 1995 study published in the Journal of the American Medical Association concluded that “sugar does not affect the behavior or cognitive performance of children,” yet the American Academy of Pediatrics reports that 93 percent of parents ask about avoiding sugar when their children are diagnosed with attention-deficit hyperactivity disorder. There is no evidence that sugar increases hyperactive behavior in children.

18. Wraps are a healthy lunch choice.

Whoever ran the marketing campaign for the wrap is a genius. How did this incredibly unhealthy and fattening product get the reputation of being a health food? A wrap (without anything in it) can have more than 300 calories. Wraps are never a healthy choice.

19. Exercise makes you hungry.

I have heard dieters say that they don’t exercise because it makes them hungry. The truth is, exercise does not significantly increase hunger. However, many people feel that they “deserve” to eat more calories because they exercised and so they allow themselves to indulge.

20. Skipping meals will help you lose weight.

Skipping meals is one of the worst things you can do when dieting. Yes, you save calories at that meal but studies show that you more than make up for those calories during the rest of the day. Also, you put your body into “starvation mode” so your metabolic rate lowers and your body tries to do whatever it can to hold onto calories. You are much better off eating small mini-meals every three or four hours.

Top Ten Food Myths

Wednesday, April 8th, 2009

Sometimes it seems that there is more nutrition misinformation floating around than actual truth.  It is hard to distinguish between what is fact- and what is mere fantasy.  Read on for the debunking of some of the more common food myths.

1. You will gain weight if you eat after 8 pm.

The bottom line for weight loss: calories in must be less than calories out.  It doesn’t matter when you eat the calories.  The problem with late night eating is that most people eat the appropriate number of calories during the day and then go overboard at night, especially when eating in front of the television.  So feel free to eat at night- just keep your total number of calories in check.

2. Fat-free foods are healthy.

Not all fat-free foods are healthy.  In fact, sugar is the quintessential fat-free food and nobody would dare say that sugar is healthy.  Many fat-free products actually contain more calories than the original.  To maintain flavor, anufacturers have to add something back when they take out the fat, and that something is usually sugar.  Be wary of fat-free snacks and always look at nutrition labels.

3.  You should not eat carbohydrates if you want to lose weight.

Carbohydrates are a part of a healthy diet!  However, some carbohydrates are healthier than others.  Whole grains, like brown rice, whole wheat pasta, and whole wheat bread, can help facilitate weight loss  by keeping you full.  Diets that don’t include any carbohydrates often fail because dieters get too hungry and feel deprived, increasing the likelihood of a binge!

4.  Some foods have ‘negative calories’.

It is a commonly-held belief that chewing and digesting certain foods burns more calories than the foods actually contain.  It is said that you can lose weight by eating these foods.  These purported miracle foods include cucumbers, celery and grapefruit.  Unfortunately, this is not true.  No food truly has ‘negative calories’.

5. Decaf coffee has no caffeine.

Decaffeinated coffee contains caffeine; it just contains less caffeine than regular coffee.  A cup of regular coffee has 100-150 mg of caffeine while a cup of decaf has 8-32 mg of caffeine.  You are better off drinking herbal tea with is truly caffeine-free.

6. Margarine is healthier than butter.

Neither margarine nor butter is healthy.  Butter has saturated fat that can increase LDL (bad cholesterol) levels, increasing the risk of heart disease.  Margarine, however, often contains trans fats which not only increase LDL but also lower HDL (good cholesterol) and can increase the risk of heart disease even more!  I recommend using a little bit of heart-healthy olive oil instead.  Olive oil contains monounsaturated fats which are proven to decrease the risk of heart disease.

7. Bananas are fattening.

One medium banana has only 105 calories and is full of fiber, magnesium and potassium which can help manage blood pressure.  Bananas also contain vitamin B6 which helps with immune function.  It is true that, per serving, bananas may have slightly more sugar, carbohydrates and calories than some other fruits.  But they are still a very healthy part of a balanced diet.

8. Cooking veggies destroys their vitamin content.

Cooking vegetables actually increases your body’s ability to absorb the nutrients in certain vegetables.  Tomatoes are a great example of this.  Lycopene, a phytonutrient that helps prevent cancer, is much stronger in cooked forms of tomatoes than in raw tomatoes.  It is true, however, that overcooking some vegetables in large amounts of water can decrease their vitamin levels by allowing the nutrients to slip out of the vegetables into the water.  To prevent this, do not overboil veggies.  Try to steam, roast, or microwave vegetables with as little water as possible and keep cooking time to a minimum.

9. High-fructose corn syrup is more fattening than regular sugar

High fructose corn syrup (HFCS) and table sugar (sucrose) contain similar amounts of fructose.  The two most commonly used types of HFCS are HFCS-42 and HFCS-55, which are 42 and 55 percent fructose, respectively. Sucrose is almost chemically identical, containing 50 percent fructose. The bottom line: there is no evidence to show any differences between these two types of sugar.  Both will cause weight gain when eaten in excess.

10. Salt causes high blood pressure and should be avoided

The truth is that restricting salt in people with high blood pressure can help lower blood pressure.  But that doesn’t mean that salt causes high blood pressure in normal individuals.  There is no reason for people with normal blood pressure to restrict their sodium intake.
