Clif Bar – Dietitian Review

Are Clif Bars Healthy?

Clif bars are a suitable snack option for people with high carbohydrate needs, such as athletes or highly active individuals. These bars are nutrient-dense and energy-dense which can help those individuals to meet their high nutrient needs. They are also generally less expensive than other energy bars on the market, making them an appealing option for those on a budget. 

Energy bars provide a processed and condensed source of nutrition which is not necessary for the average person to meet their nutritional needs. A whole-food-based snack such as peanut butter with apple slices or yogurt and fruit would provide protein, fats, and complex carbohydrates in a more satiating format.

Compared to lower-calorie nut-based bars or granola bars on the market (non-energy bars), Clif bars are much higher in sugar*. A balanced snack bar or protein bar may be a more suitable snack bar alternative for the average adult than a Clif bar or other energy bar.

*the sugar content of Clif bars is comparable to other energy bars on the market.

Pre-workout snack:

These bars may be suitable for a pre-workout snack for athletes or active individuals looking for a convenient snack. Though the timing of this pre-workout snack will depend on the individual’s digestion, most people would tolerate a Clif bar if consumed ~2 hours before exercise.

There are 250-260 calories per Clif bar. This is moderate compared to other energy bars on the market.

Are Clif bars good to eat after a workout?

Are Clif bars a good protein bar?

Clif bars contain ~10-11g of protein per bar which is an appropriate snack portion of protein for the average adult. However, Clif bars are energy-dense and high in added sugar, which may not be necessary for the average adult to meet their daily nutritional needs.

Is it OK to eat a Clif bar every day?

Most people do not need to consume energy bars to meet their daily nutritional requirements. A protein bar or nut-based bar (non-energy bars) is a more suitable option for a daily snack for the average adult.
