It's possible. While it's too soon to say, "an apple a day keeps the doldrums (feeling low & depressed) away," Researchers are studying the links between what we eat and how we feel. There is evidence that changing your diet can alter your metabolism and brain chemistry, ultimately affecting your energy level and mood.
Foods can boost energy in three ways: by providing sufficient calories, by delivering stimulants like caffeine, and by increasing the metabolism to burn fuel more efficiently. As for mood, the best foods are those that stabilize blood sugar and trigger feel-good brain chemicals, such as serotonin.
Smart Carbs
Cashews, Almonds, and Hazelnuts
These nuts are rich
in protein and magnesium, a mineral that plays a key role in converting
sugar into energy. Being low on magnesium can drain your energy. Good
sources of magnesium include whole grains, particularly bran cereals,
and some fish, including halibut.
Brazil Nuts
Add Brazil nuts to the mix for
selenium, a mineral that may be a natural mood booster. Studies have
linked low selenium to poorer moods. Smaller amounts of selenium are
also found in meats, seafood, beans, and whole grains. Don't overdo it:
Too much selenium is harmful. A new study shows that taking too much selenium could adversely affect the heart by raising LDL (Bad) cholesterol levels. Other studies have shown that high levels of selenium increase the risk of type 2 Diabetes and open angle glaucoma.
Lean Meats
Lean pork, lean beef, skinless chicken, and turkey are sources of protein that include the amino acid tyrosine. Tyrosine boosts levels of two brain chemicals (dopamine and norepinephrine) that can help you feel more alert and focused. Meats also contain vitamin B-12, which may help ease insomnia and depression.
Salmon
Fatty fish, such as salmon, is
rich in omega-3 fatty acids, which may protect against depression and
be good for heart health. Besides fish, sources of omega-3 include nuts
and dark green leafy vegetables.
Leafy Greens
Folate is another nutrient
that may lower the risk of depression. Find it in leafy green vegetables, legumes, nuts, and citrus
fruits.
