Are you a health nut and zombie fanatic? Believe it or not the two go limb in limb. Very similar to the human food pyramid, the zombie food pyramid was designed to help those get the proper nutrients and right amount of calories needed to maintain a healthy diet.

An image by artist Mike Capen for Threadless.com displays the six important food groups necessary for a healthy zombie diet. The food groups include: Bones, stomach, intestines, liver, heart and lungs, and of course a heavy helping of brains. Brains are the most important food group of the zombie food pyramid, so what foods as humans can we eat to help boost our brain?

Avocados

Avocados are a fatty fruit which help blood flow, making it a great food to eat for brain health. According to WebMD, the fruit also lowers blood pressure which helps contribute to a healthy brain. Since avocados are high in calories, WebMD suggests eating 1/4 to 1/2 of an avocado a day.

Blueberries

Steven Pratt, MD, author of Superfoods Rx: Fourteen Foods Proven to Change Your Life says that this delicious fruit should actually be called brainberries. Studies on animals have revealed that eating blueberries can help the brain from oxidative stress, and also has the ability to reduce age-related conditions like Alzheimer's disease or dementia. WebMD suggests eating at least a cup of blueberries a day.

Walnuts

Walnuts have a high amount of antioxidants which is very beneficial in combatting damage to the brain, says MyHealthNewsDaily.com. You don't have to limit yourself to this brainy-looking nut though. WebMD says that eating ant nuts and seeds can befit your brain because they are great sources of vitamin E. Snack on nuts throughout the day to feel their benefits.

Coffee and Tea

Freshly brewed tea, which contains caffeine, can help boost brain power says WebMD. Drinking tea may lead to enhanced memory, focus and mood. WebMD suggests drinking around two to three cups of tea a day. MyDailyHealthNews.com states that coffee can also be beneficial to the brain, in that the caffeine can be therapeutic for someone with Alzheimer's disease.

Salmon

Salmon is rich in omega-3 fatty acids, which WebMD says is essential for brain function. MyHealthNewsDaily.com echoes WebMd, stating that eating omega-3 fatty acid foods can help slow typical cognitive decline. A 4-ounce serving is suggested two to three times a week.

Keeping a healthy brain is important whether a zombie apocalypse occurs or not. A strong brain will be able to help you prepare for a zombie apocalypse, like making an emergency kit and an emergency plan. And if survival doesn't seem feasible in a zombie infested world, then at least you will have a delicious brain for them to feast on.
