Most people need about 50 - 70 grams of protein each day, and people trying to gain muscle mass require even more. When choosing which protein bar is right for you, consider your goals. Some protein bars are better for gaining muscle, while others are better for maintaining weight. Remember that protein bars aren’t always the best way to lose weight, especially bars that are high in calories or fat. For weight loss, consider meal replacement shakes as an alternative to protein bars.
What are the best protein bars?
We considered nutrition, taste and price to select our top protein bars. All these bars have at least 7 grams of protein and no unhealthy ingredients such as high fructose corn syrup. Remember there isn’t one bar that’s right for everyone or one bar with everything you need. When deciding which protein bar is best for you, consider your nutritional goals and dietary restrictions — but don’t forget to factor in your flavor and texture preferences.
Not all protein bars are good for you. The best protein bars provide a balance of protein, carbs, fiber, fat and other nutrients. In addition to being a convenient protein source, the benefits of protein bars include raised energy levels, increased calorie burning and decreased appetite. In combination with exercise and other healthy habits, eating protein bars can increase lean mass, power and strength.
Nutritionists don’t recommend more than one
protein bar per day
Athletes often use protein bars to recover after an intense workout. Others eat protein bars to help stabilize blood sugar and reduce blood pressure or cholesterol levels. Protein is especially important for menopausal women because it works with calcium to increase bone strength.
Protein is an essential macronutrient everyone needs in their diet. All proteins break down into amino acids. Animal protein sources include meat, eggs and dairy, and plant proteins sources include nuts, beans and lentils. Plant-based proteins are considered to be incomplete proteins because they lack some essential amino acids, but complementary plant-based proteins can be eaten together to form complete proteins. Foods rich in animal proteins also often contain vitamins B12 and D, plus omega-3 fat, heme-iron and zinc. People with high plant-protein diets are at lower risk for heart disease, obesity and Type 2 diabetes.
What to look for in a protein bar
Look for protein bars that are high in protein with moderate fiber and low sugars and carbs. Before you make a purchase, compare protein bar nutrition facts to check for synthetic ingredients and added sugar. Consider your budget as well — protein bar prices range from less than $1 to $4 or more per bar. You should also pick a taste profile you enjoy.
The role of protein in your diet is a significant factor when deciding which protein bar is right for you. If you’re trying to gain lean body mass, for example, look for protein bars with creatine. Keep in mind that many protein bars are high in calories and carbohydrates. For weight loss, look for bars with a 2:1 ratio of protein to carbohydrates. Some diets require you to count net carbs, which is the number of carbs minus the amount of fiber and a portion of sugar alcohols, instead of total carbs. Companies also sell vegan or animal protein bars with supplemental vitamins or minerals for those with special dietary needs.
