In the 1980 movie, "The Shining," Jack Torrance (Jack Nicholson) breaks through a door with an axe ("Heeere's Johnny!") and tries to murder his wife and son. Was that just another low-blood-sugar day for the enraged Jack? Maybe.

Hypoglycemia (low blood sugar) can make you feel, well, not yourself. And according to recent research from Ohio State University, hypoglycemia not related to diabetes can fuel tensions between married folks, even triggering overt acts of aggression.

You can get blood sugar dips because you miss a meal; eat an extreme diet; drink too much alcohol on an empty stomach; or exercise intensely without proper nourishment. (Hypoglycemia related to Type 1 or Type 2 diabetes can happen if diabetes medication lowers blood sugar too much, you eat too little of the right foods, or you exercise without adjusting your medications.)

We might dispute some of the study's findings - it takes a lot of energy to get really angry, and with low blood sugar you're much more likely to fall asleep than become aggressive - but that aside, the study does point out that a healthy diet helps create a happy marriage.

Here are some of our favorite foods that will help you get along: Salmon and sea trout are loaded with omega-3s that may lift your mood. Inflammation-soothing kiwi can cool you down. Pumpkin seeds and whole-grain barley help keep blood sugar steady for hours. Red hot chili peppers stimulate release of mood-lifting endorphins. Hey, you never know where new flavors and spices can lead!
