The bakery at Safeway grocery offers a variety of bagels, including the jalapeno cheese bagel. Adding toppings to your bagel changes the calories, so keep the toppings in mind, too, if you're counting your daily calories.

According to My Fitness Pal, each Safeway jalapeno cheese bagel has 260 calories. However, since the recommended serving size is half a bagel, you'd consume only 130 calories if you limited yourself to the serving suggestion.

A single jalapeno cheese bagel from Safeway has 2 g of fat, with one of those grams being saturated, 48 g of carbohydrates, 10 g of protein, 2 g of dietary fiber and 2 g of sugar. One bagel also has 16 percent of a person's daily requirements of iron.

Butter and cream cheese are common toppings for bagels. Each tablespoon of plain cream cheese adds 51 calories to a bagel, while a tablespoon of butter adds twice that much: 102 calories.
