Start each day with a mix of high-quality protein and beneficial fats to build the foundation for an energized day. Avocado provides the monounsaturated fat that helps blood circulate better, which is essential for optimal brain function. Worst alternative: a trans-fat-filled, sugar-laden cream cheese Danish.
Green it: If you decide to mix your avocado with eggs, make sure your supplementary protein is free range, cage free, or organic.
These delicious berries are one of the best foods for you, period, but they’re very good for your brain as well. Since they’re high in fiber and low on the glycemic index, they are safe for diabetics and they do not spike blood sugar. Blueberries are possibly the best brain food on earth:
they have been linked to reduced risk for Alzheimer’s, shown to improve learning ability and motor skills in rats, and they are one of the most powerful anti-stress foods you can eat. Avoid: dried, sweetened blueberries.
Green it: buy local and organic, and be mindful of seasonality. When blueberries are out of season, opt for cranberries, grapes, goji berries, blackberries or cherries to get your brain boost.
Nuts contain protein, high amounts of fiber, and they are rich in beneficial fats. For getting an immediate energy boost that won’t turn into a spike later, you can’t do better than nuts. The complex carbs will perk you up while the fat and protein will sustain you. Nuts also contain plenty of vitamin E, which is essential to cognitive function. You don’t have to eat raw, plain, unsalted nuts, but do avoid the ones with a lot of sweetening or seasoning blends. Filberts, hazelnuts, cashews, and walnuts are great choices, with almonds being the king of nuts.
For those avoiding carbs, macadamia nuts are much higher in fat than most nuts. By the way, peanuts just aren’t ideal. Aside from the fact that many people are allergic, peanuts have less healthy fat than many other types of nuts…maybe that’s because peanuts are not actually a nut! They’re still much better than a candy bar (While “nut” is in their name, peanuts are in fact legumes and actually grow underground).
Green it: try to choose organic, raw nuts, and if you can’t get those, at least avoid the tins of heavily-seasoned, preservative-laden nuts that may have taken many food miles to get to their destination.
Try sunflower seeds, sesame seeds, flax seed, and tahini (a tangy, nutty sesame butter thattastes great in replacement of mayo and salad dressing). Seeds contain a lot of protein, beneficial fat, and vitamin E, as well as stress-fighting antioxidants and important brain-boosting minerals like magnesium.
Green it: Again, just look for organic and try to avoid the highly-seasoned, processed options. In general, things like fruits, vegetables, seeds and nuts are pretty low-impact, environmentally speaking, in comparison to meats.
Opt for the fruit over the juice so you get more fiber. Pomegranatescontain blueberry-like levels of antioxidants, which are essential for a healthy brain. Your brain is the first organ to feel the effects of stress, so anything you can do to offset stress is a smart choice.
Green it: pomegranates are seasonal and not generally local for most of us, so enjoy sparingly and rely on other berries like acai, grapes and cherries when you can’t get this fruit.
6. Green Leafy Vegetables
Spinach, kale, chard, romaine, arugula, lolla rossa – whatever green you like, eat it daily. Green, leafy vegetables are high in iron. Many people tend to be deficient in iron, which is too bad, because the deficiency is linked to restless leg syndrome, fatigue, poor mood, foggy thinking, and other cognition issues.
Green it: choose organic, and shop at your farmers’ market or order from a local CSA. Leave out the red meat a few days a week and rely on a big, well-seasoned green stir fry or salad.
Go figure, but tomatoes don’t usually make the brain-boosting food lists. Tomatoes contain lycopene, an antioxidant that is particularly good for your brain – it even helps prevent dementia. You have to cook tomatoes to get the lycopene. But this does mean that ketchup is good for your brain. Although because of the sugar in it, you should look to other sources for most of your lycopene intake, such as fresh tomato sauce.
Green it: try to eat tomatoes that are local and get your lycopene in vitamin form when tomatoes aren’t in season. You’ll know when that is – the tomatoes will be pale, tasteless, and pithy.
8. Olive Oil
Though we know the brain does need a small, steady supply of glucose, don’t overlook fat. Studies have consistently shown that a low-fat diet is not the health boon we hoped it would be (remember the 90s low-fat craze?). In fact, avoiding fat can increase foggy thinking, mood swings, and insomnia. A diet rich in healthy fats is essential to clear thinking, good memory, and a balanced mood. Your brain is made of fat, after all.
One study of men found that those who relied on the processed vegetable fats found in salad dressings, snacks and prepared foods had 75% higher rates of mental degradation (dementia, memory loss) than men who ate healthy fats. Most processed foods and fast foods use corn oil, palm oil, soybean oil and other Omega-6 fats. You don’t want Omega 6 fats. Even saturated fat is safer than Omega 6’s.
Choose healthy fats such as those present in olive oil, nut butters, nuts and seeds, flax, oily fish, and avocados. Avoid processed fats found in pastries, chips, candy bars, snacks, junk food, fried foods and prepared foods. Eating the wrong fat can literally alter your brain’s communication pathways.
Green it: look for organic, local, or farmers’ market options when it comes to your food. You should also explore herbal remedies for mood swings and brain health.
You have to brew tea fresh or you won’t get the benefits of all those catechines (antioxidants) that boost your brain. Because many teas contain caffeine, don’t have more than 2-3 cups daily.
Green it: buy organic, fair trade loose leaf or packets to support sustainable business practices.
