He is the author of The Habit Trap, due out in early 2027. Aug 26, 2015 12:00 PM UTC Long-term couples know all too well the perils of the early evening hours: that touchy time after work but before dinner hits the table. It’s prime time for getting “hangry”, a handy portmanteau for hungry and angry. People commonly feel an uptick in anger or aggression when they’re hungry, says Dr. Brad Bushman, a professor of psychology at Ohio State University. “The brain needs fuel to regulate emotions, and anger is the emotion people have the most difficulty regulating,” he explains. Your brain’s primary fuel source is glucose, which your body makes from the foods you eat. And as far as fuel consumption goes, “the brain is a very demanding organ,” Bushman says. While your brain constitutes just 2% of your body weight, it uses 20% to 30% of the energy you consume, he says. **MORE**: [Here’s What Eating Does To Female Desire](http://time.com/3988514/women-romance-food/) So why do you feel hangry in the evening, but not first thing in the morning when you’ve gone the whole night without food? Willpower and self-control tend to flag as the day wears on, which further torpedoes your mood, Bushman says. That’s bad news for your partner. Bushman’s research has shown that compared to well-fed couples, glucose-deprived people tend to stick more pins into voodoo dolls meant to represent their spouses. The underfed study participants were also more likely to blast their partners with unpleasant noises. When your brain is struggling to control its emotions, you’re likely to lash out at the people with whom you feel most comfortable, Bushman and his colleagues concluded. So loved ones and close friends tend to bear the brunt of your glucose-starved brain. There seems to be another, deeper layer to your hunger-induced emotional fragility. Some of the same appetite hormones that signal to your brain _It’s time to eat!_ also fire up those brain regions linked with stress and anxiety, says Dr. Paul Currie, a professor of psychology and neuroscience at Reed College in Portland, Oregon. In fact, Currie says some of those regions overlap. **MORE**: [The 14 Worst Kinds of Late People](http://time.com/3984571/worst-types-of-late-people/) All of this makes sense, he says, when you look at the necessity of food in “evolutionary” terms. “If you’re an animal and you’re hungry, you need food to survive,” he explains. “So it’s natural that you would feel anxious and irritable and preoccupied until you’ve met that need.” What’s more, this stress-hunger crosstalk may go in both directions. Research has found that people tend to reach for food (especially energy-dense junk food) when feeling stressed. Of course, the chemical and neuronal processes going on in your hungry brain are complex and vary from one person to another, Currie says. So while you may have no problem keeping your cool before dinner, your friend may be an anger-grenade with a pulled pin. Fortunately, there’s a simple solution: eat something. If you know your mood tends to plummet before dinner, a preemptive afternoon snack that includes some carbs and protein—like peanut butter and apple, or some yogurt with berries—can help you hold onto your typically sunny disposition. ### You Asked: Your Top 10 Health Questions Answered  You Asked: Are Cleanses Healthy?

Illustration by Peter Oumanski for TIME ## Transcript [00:00] [ MUSIC ] [00:07] All five of our experts are nuts for almond butter. A [00:12] standard, two tablespoon serving of almond, butter [00:14] has a hundred and ninety- six calories, seven grams of [00:17] protein, and a whole bunch of fat. That's just fine with [00:20] Kristin Kirkpatrick who says the lack of carbs and an [00:23] abundance of protein and healthy fat make almond [00:25] butter a dieter's best friend. It's a good source of fiber [00:29] too. Most of us fall far short in the fiber department [00:33] and a serving packs an impressive 3. 3 grams of fiber [00:37] about 13 % of the FDA's daily recommended total. Keri [00:40] Gans recommends Recommend spooning some into [00:43] your morning smoothie or a bowl of oatmeal. But David [00:46] Katz warns that you should buy the kind that's made [00:48] from just nuts. Additions of salt, sugar and oils can [00:52] make the butter less healthy. Research continues to [00:55] mount that a diet that contains nuts may help reduce [00:58] the risk of heart disease, diabetes and stroke. [01:00] [ MUSIC ] Research by David Jenkins suggest that the [01:04] more nuts you eat the lower your cholesterol. However, [01:07] almonds don't have a great environmental reputation. [01:10] Growing almonds requires a lot of water, as much as [01:13] one gallon per nut. But David Zetland says that [01:16] forfeiting almonds isn't the solution. Taking better care [01:20] of our environment as a whole will allow us all to keep [01:23] snacking on these delicious and healthy nuts.
