What is the Actual Shelf Life of a Clif Bar?

If you are into an active life; running, hiking, cycling, or any other sport, you burn calories fast and need energy fast. Clif bars are designed to fuel your muscles for exercise that lasts for an hour or more.

But what is the shelf life of Clif bars? They should ideally be consumed 2 to 3 hours before you begin your exercise. They are a convenient boost to fuel your muscles. They are lightweight, and do not take up a lot of space in a hiking pack, day pack, or pocket, but they pack a punch.

But what is the actual shelf life of a Clif bar? Officially, they have a shelf life of 1 year from the date of purchase. However, extensive testing of Clif bars has shown that Clif bars are still edible more than 2 years after the best before date on the packaging if they have been stored away from heat and their wrappers are intact.

They can be purchased individually, in packs of 6, 12, 24, or 36, or as mini bars.

How Do You Know if a Clif Bar is Edible?

The ingredients in a Clif bar that spoil are the oils and sugar. These will turn rancid over time. As the oils and sugar go bad, the smell, appearance, and taste of the bar will be remarkably different.

A fresh Clif bar will be glossy and soft. If the bar is squishy and has an oily feel, it is not fresh and should not be consumed.

If the packaging is damaged, the bar may be off or it may have been tampered with. I do not recommend that you eat it.

If the bar has been exposed to bacteria, the packaging may become inflated and springy. If the package is inflated – like a balloon – be wary, it is likely to be spoiled.

Whether the packaging is intact or not, inspect the bar carefully when you open it. Over time, the bar will dry out. If it looks dry and does not have its usual feel, it is not going to be good to eat.

The best way to judge if your Clif bar is edible or not is to do the sniff test. If the packaging is intact and you get a nasty whiff when you open it, throw that bar away!

I do not have a strong stomach; I gag very easily. If it does not pass the sniff test, that is all the encouragement I need to throw it away.

If you are brave enough to taste the bar for a final verdict, go for it – but I do not recommend going much further than a tiny taste. If the taste is not what you were expecting, if it tastes a bit odd, or if it tastes downright nasty, spit it out and throw the bar away.

Finally, if the bar is two or more years past the best before date it is safer not to eat it.

What Nutritional Value is in a Clif Bar?

I am going to break this down to give you an idea of the nutritional value per bar versus how much of your daily diet each value represents.

One Clif bar contains:

  1. 250 calories (of the recommended daily allowance of 2000 – 3000 calories for adult men, and 1600 to 2400 calories for adult women)
  2. 45 grams (of carbohydrates of the recommended daily allowance of 225 to 325 grams)
  3. 9 grams of protein (of the recommended daily allowance of 0.36 grams per pound of body weight)
  4. 21 grams of sugar (of the recommended daily allowance of no more than 30 grams for adults)
  5. 5 grams of fat (of the recommended daily allowance of 44 to 77 grams if you eat 2000 calories in a day)

The carbohydrates are what fuel muscles, and give you strength and endurance for long, drawn out, intense exercise periods.

How to Emaximize Shelf Life

To ensure your Clif bar stays fresh for longer, there are a few things you can do:

  1. Check the packaging while you are in the store before you purchase it. If the packaging seems inflated or if there are any tears in the packaging, do not buy it.
  2. Check the expiration date before you buy, do not buy bars that have surpassed their best before date or that are near expiration.
  3. Store your Clif bars in a cool, dry place, well away from heat.
  4. Storing them in a closed carry-all will ensure they stay safe from scavengers.

Conclusion

Clif bars are a great way to boost your energy levels; however, they are not nutritious enough to sustain you. They are not to be used as meal replacements.

As a hiker, I always packed 2 bars per person per day. We did not go over that because in excess they can make you feel really ill.

I also feed them to my father when he is feeling a bit run down, and needs a boost to get him up and moving.

Keeping them stored in your car is a definite no-no, especially if you live in a very hot climate. Heat destroys them!

It is not recommended to feed protein bars to kids. Just as with power drinks, the nutritional values will be excessive for children. You will definitely have your kids bouncing off the walls.

If your child is ill and needs a boost, give them the mini bar. It has the same content, but a smaller payload.

It is safe to buy in bulk and store them for long term consumption, provided you store them away from heat. When you replace them, only open the new package when the last bar from the older package is finished.
