Feed your Brain: 10 foods that Build Brain Strength

We often think about reshaping our bodies through exercise, but have you ever thought about reshaping your brain?

The human brain has an incredible ability to adapt and react and make new connections and pathways. With the right kind of stimulation and the right kind of mindset, you can reshape your brain. A healthy lifestyle and a good diet will help you unleash the power inside your brain.

Check your sleep habit before changing your diet

The better you sleep, the healthier you eat. This is a scientific fact. If you are sleep deprived, your body secretes a digestive hormone called ghrelin, which increases your appetite. It also releases less leptin, a hormone that signals you to stop eating when you are full.

When these imbalances occur, your metabolism is out of whack and not only do you crave sugar and high fat foods, you eat them in large quantities to combat fatigue. With insufficient sleep, your body also secretes fewer feel good hormones – serotonin and dopamine. Your body will ache and feel cheated as it relies on these hormones to feel great. To compensate, you will eat plenty of sugary foods to re-capture that good feeling sensation. Should you eat this way for too long, unleashing the power inside your brain becomes a struggle.

What about glucose and caffeine?

Refined sugar contains glucose and fructose. When you eat sugary foods, your brain uses glucose for energy. Both glucose and caffeine react the same way – they quickly boost your mental ability and energize you, but their effect is short lived. Over a period of time, too much glucose or caffeine impairs mental and physical functions. I know what you’re thinking; there’s a lot of talk about coffee being good for you. A bit of coffee is fine; it contains antioxidants and it gives you a kick-start. Health experts recommend a daily intake of 300 mg of caffeine (3-4 cups) and 30-45 gm of sugar.

Ten foods to feed your brain

Your brain needs healthy blood vessels as much as your heart does. Choosing foods that are good for your heart will also be good for your brain. The key to healthy eating is moderation and variety.

  • Omega-3s: without these fatty acids, your brain is like a car running on empty. When a car is empty, it stops. Your brain won’t stop, but it can shrink. New studies show an increase in the hippocampus (where the brain forms and stores memories) and in gray matter volume in people with higher than average levels of omega-3s in their blood. Fatty acids are vital to brain tissues and cells. To get plenty of omega-3s in your diet, eat fish twice a week or take fish oil supplements. Other sources are nuts and seeds, flaxseed oil, squash, kidney beans, spinach, broccoli and soybeans.

    Colorful fruits and vegetables: contain antioxidants, the substances that protect your brain against cell damage by blocking free radicals. Free radicals are the “bad guys” that work with damaged cells that cause diseases, from skin wrinkles to cancer. Examples are dark green leafy vegetables, berries (especially blueberries), bananas, apricots, melons and mangos. Red coloured foods, such as tomatoes and red cabbage are rich in lycopene – a very powerful antioxidant.

  • Pumpkin seeds: when I crave a crunchy snack, I reach for pumpkin seeds instead of pretzels or crisps. Just a handful is packed with protein, fiber, minerals, vitamins and antioxidants. Both seeds and oil are rich in zinc and fatty acids. Either raw or roasted, they’re nature’s perfect snack that promotes healthy skin, improves your brainpower and protects against diseases such as high blood pressure, arthritis, osteoporosis and cancer. The seeds are high in tryptophan, a compound that prevents depression and helps you sleep at night. At Halloween, when you carve that big pumpkin, think twice before throwing out those seeds.
  • Eggs: contain B12, lecithin and essential fatty acids that protect against brain shrinkage, which is often seen in Alzheimer’s. As we age, our body’s natural choline weakens. Egg yolk is high in choline, which nourishes brain cells and improves memory. Since the yolk is also high in cholesterol, healthy people shouldn’t eat more than three eggs a week. Other sources of choline are soybeans, peanuts, kidney beans, broccoli, cauliflower, brussel sprouts and black beans.
  • Avocados: this fruit long deemed “too fat” has been put on the back burner. It’s time to bring the avocado at the front for brain health and anti-aging. It contains monounsaturated fats (good fat) and fiber. It’s high in vitamin E, potassium and magnesium. It has anti-inflammatory properties; it lowers blood pressure and improves circulation to the brain. A few slices of avocado per day and as a side dish is sufficient.
  • Whole grains: complex carbohydrate sources give a steady stream of energy to your brain. They contain fiber, vitamins and minerals. Choose whole-wheat bread and whole grain pasta, cereals or rice. Go brown instead of white. Wheat, bran, wheat germ, barley, oatmeal and quinoa contain folate and B vitamins that help brain function and memory. Lentils, whole beans and starchy vegetables are also complex carbohydrates.
  • Green tea: the anti-inflammatory compounds and catechins in the tea can keep your mind sharp and fresh. Green tea helps you to relax and resist mental fatigue. Drinking two cups of green tea per day can help prevent cognitive impairment.
  • Dark chocolate: a bit of dark chocolate is fine. Dark chocolate with 70 percent or more pure cocoa is naturally high in flavonols that increase blood flow to the brain and boost concentration. Before reaching for coffee, try a piece of chocolate instead.
  • Red wine (or grape juice):  red wine in moderation (1 glass a day for women; 2 for men) can improve memory and cognition. Red wine is rich in resveratrol, an antioxidant that improves blood circulation in the brain. It can reduce the risk of stroke and Alzheimer’s. Cranberry juice, berries, grapes and peanuts contain resveratrol.
  • Spirulina:  the last, but not the least. My neighbor, out of concern, gave me a brochure on spirulina and she urged me to get some for my family and me. My two girls and I are vegetarian and my husband has significantly cut back on meat. We are all taking spirulina on a daily basis and we feel great.  Spirulina is a blue-green algae and is 100% natural. It is often described as the most complete food source. Spirulina comes in capsules, powder or flakes. It can be dissolved in juices or sprinkled on food. It is very high in protein, minerals and vitamins, including B complex vitamins. It is a source of iron, folic acid, magnesium and calcium. It is high in beta-carotene, an antioxidant vitamin important for your eyes. There is increasing evidence that spirulina prevents cognitive diseases and maintains brain health.
