Boost Your Mood and Energy Without a Blood Sugar Crash

Sugar is a delicious and convenient item we sometimes choose when we need a mood or energy lift—especially in the afternoons. And, in the moment, right after we enjoy a sugary snack or drink, we seem to feel a bit better. But it doesn’t last long and is inevitably followed by the infamous “blood sugar crash.” This is when you feel even more sluggish and unproductive than you did before you had the sugary treat.

Can sugar really improve your mood and energy? More importantly, when you need a boost, what are the best things to eat and drink to avoid “crashing?”

Sugar For Your Mood?

We seem to feel a bit more light-hearted after a sugary snack. Or do we? Researchers have studied the effects that sugar has on our moods. Overall, there have been many mixed results. This recently led a team to put these conflicting studies together and see what the overall big picture says. After analyzing 31 studies, they published their somewhat surprising findings just a few months ago.[Ref 1]
They found that eating or drinking sugary items did not improve any aspect of mood at any time-point afterward. That’s right—objectively, we don’t feel any happier after we consume sugar.

Other researchers say, “the evidence to date does not support the specific subjective mood-enhancing effects of glucose [sugar] intake.”[Ref 2]
These studies looked at the short-term effects of sugar on moods, but what about in the longer-term? When it comes to long-term mood, a review of 10 studies found that regularly drinking sugar-sweetened beverages like soda increases the risk of depression.[Ref 3] Yes, it makes you feel even worse.

Overall, there isn’t much hard evidence that sugar is the mood-booster we think (and maybe want) it to be; and it can even crash our moods.

Sugar for Energy?

What about sugar’s ability to reduce fatigue and give us mental energy? One study looked at the effect sugar had on people’s ability to concentrate, remember things, and answer test questions.[Ref 4] They thought sugar would give the test-goers energy and alertness. However, the results showed no improvement.
Another study showed that sugar’s ability to improve mood only worked when people were told they were consuming sugar.[Ref 5]

These show that sugar doesn’t seem to give us the mental energy we think it does. But, does it crash our mental energy?

This recent study says, yes. Researchers found that within 30-minutes after consuming sugar people felt even more fatigue. Within 30 more minutes, they were even less alert.[Ref 1]

As you can see, sugar crashes not only our moods but also our energy.

Avoid Blood Sugar Crashes with These Foods

There are delicious and healthy foods that boost your energy. These ones are full of nutrients like vitamins, minerals, and antioxidants and won’t give you a blood sugar crash.

Foods like:

  • Berries, including strawberries (for your heart, blood sugar, and anti-aging effects)
  • Leafy greens (for your arteries, eyes, and muscles)
  • Legumes (e.g., beans, lentils, chickpeas, and split peas) help slim your waist and protect you from diabetes

It can be very quick and easy to incorporate berries, greens, and legumes into your meals. Try having a leafy salad for lunch or dinner (greens topped with berries or legumes), add fresh or frozen berries to your breakfast oatmeal, include legumes with dinner, or even blend fresh or frozen berries and greens together with almond or soy milk for a delicious smoothie.
