Diet can go a long way toward increasing or lowering energy levels. No one wants to consume foods that will make it harder for them to get through the day, so the following are a handful of foods that pack an energetic punch.

1. Cashews: Cashews, which are high in magnesium, help to convert sugar into energy. Magnesium deficiency can lead to low energy levels, so nuts that are high in magnesium, including cashews, can provide that mid-afternoon jolt that some people are seeking. Cashews are high in calories, so it’s best for those looking to lose weight or maintain healthy weights to adhere to serving suggestion guidelines.

2. Skinless chicken: A study from researcher Judith Wurtman of the Massachusetts Institute of Technology Clinical Research Center found that alertness tends to increase when the brain produces the neurotransmitter dopamine and the hormone norepinephrine. Skinless chicken contains an amino acid known as tyrosine that helps in the production of both dopamine and norepinephrine. If skinless chicken is not available, other foods that may provide this same effect include fish, lean beef and eggs. In addition, lean meats like skinless chicken contain enough vitamin B to help ease insomnia.

3. Salmon: Omega-3 fatty acids can help the body fight inflammation, which has been linked to a host of ailments, including chronic fatigue. Salmon is also high in protein, which can eliminate the mid- to late-afternoon hunger pangs that can derail healthy diets and contribute to weight gain.

4. Beans: Beans are loaded with fiber, and that’s a good thing for energy levels. Like magnesium, which can also be found in beans, fiber takes awhile to digest, extending the energy-boosting properties of foods loaded with fiber. In spite of the growing movement to eat and live healthier, many adults still do not include enough fiber in their diets. Men and women can consult with their physicians to determine how to make that happen, but eating more beans is a good start.
