Meryl Brandwein RD/LDN : Nutrition Bars
Nutrition bars go by many names including “protein bars,” “energy bars,” and “meal-replacement bars.” Nutrition bars are generally much larger by weight than snack bars (such as granola bars) or candy bars (such as chocolate bars) and have a much higher protein content –generally 10 grams to 30 grams of protein in a nutrition bar versus little or no protein in a snack bar or candy bar.
Many bars have now added a fiber category and add that on as a benefit to the bar. Those with 2.5 mg of fiber are claiming to be good sources of fiber, while others containing 5mg. or more can claim to be an excellent source. The recommendation for fiber is at least 20grams per day.
Many of the fats in some bars are saturated, and some bars also contain hydrogenated oils as well as high fructose corn syrup.
Another concern in the area of nutrition bars is the protein it contains. Most use soy, whey, or casein isolates. These protein isolates are usually obtained by a high temperature process that over denatures the protein therefore making it almost useless. This process also can create nitrates and other carcinogens. Soy protein isolates also are high in mineral blocking phytates and potent enzyme inhibitors that can lead to abnormal cell growth.
Sugar Alcohols are used in some bars to reduce the calorie content of the bar. Sugar alcohols are maltitol or lactitol. While these provide fewer calories than sugar they can cause bloating and gas and in very high amounts can act as a laxative.
It is therefore it is recommended that the nutritional bars be used primarily as a snack or as a supplement to the diet, but not used to completely replace a meal. Bars may be a sufficient way to enhance energy temporarily, but should not be used on a long term basis to provide the nutrients lacking in ones diet.
Some of the better bars on the market are the “raw” food bars or the natural food bars. These bars tend to have more natural ingredients without added chemicals or additives. Keep in mind that these bars should primarily be used as a snack and not to replace meals. They are great as an after school snack, and are good for those playing sports, for those who need that something extra to get through a practice. While they are a better option than some of the more commercial types of bars, these bars can have a high calorie count so use them wisely.
