How Food Affects Your Moods
Can your diet help put you in a good mood (or a bad one)?
Can your diet really help put you in a good mood? And can what you choose to
eat or drink encourage bad moods or mild depression?
While certain diets or foods may not ease depression (or put you instantly
in a better mood), they may help as part of an overall treatment plan. There's
more and more research indicating that, in some ways, diet may influence mood.
We don't have the whole story yet, but there are some interesting clues.
Basically the science of food's affect on mood is based on this: Dietary
changes can bring about changes in our brain structure (chemically and
physiologically), which can lead to altered behavior.
How Can You Use Food to Boost Mood?
So how should you change your diet if you want to try to improve your mood?
You'll find eight suggestions below. Try to incorporate as many as possible,
because regardless of their effects on mood, most of these changes offer other
health benefits as well.
1. Don't Banish Carbs -- Just Choose 'Smart' Ones
The connection between carbohydrates and mood is all about tryptophan, a
nonessential amino acid. As more tryptophan enters the brain, more serotonin is
synthesized in the brain, and mood tends to improve. Serotonin, known as a mood
regulator, is made naturally in the brain from tryptophan with some help from
the B vitamins. Foods thought to increase serotonin levels in the brain include
fish and vitamin D.
Here's the catch, though: While tryptophan is found in almost all
protein-rich foods, other amino acids are better at passing from the
bloodstream into the brain. So you can actually boost your tryptophan levels by
eating more carbohydrates; they seem to help eliminate the competition for
tryptophan, so more of it can enter the brain. But it's important to make smart
carbohydrate choices like whole grains, fruits, vegetables, and legumes, which
also contribute important nutrients and fiber.
So what happens when you follow a very low carbohydrate diet? According to
researchers from Arizona State University, a very low carbohydrate (ketogenic)
diet was found to enhance fatigue and reduce the desire to exercise in
overweight adults after just two weeks.
2. Get More Omega-3 Fatty Acids
In recent years, researchers have noted that omega-3 polyunsaturated fatty
acids (found in fatty fish, flaxseed, and walnuts) may help protect against
depression. This makes sense physiologically, since omega-3s appear to affect
neurotransmitter pathways in the brain. Past studies have suggested there may
be abnormal metabolism of omega-3s in depression, although some more recent
studies have suggested there may not be a strong association between omega-3s
and depression. Still, there are other health benefits to eating fish a few
times a week, so it's worth a try. Shoot for two to three servings of fish per
