1. Quinoa

Quinoa is member of the goosefoot family, and is technically a seed, though it is often referred to as a grain. Quinoa is quick cooking (15-20 minutes) and makes the perfect base for salads, side dishes and morning porridge. As quinoa is gluten-free, protein-rich and easy to digest, it’s considered an ideal endurance food.
2. Kale

The Mother of all dark, leafy greens, kale is a hearty vegetable that’s chock full of antioxidants, vitamins and minerals. It also contains chlorophyll, which enables plants to receive energy from the sun. When you eat kale (and other dark green veggies) you absorb and assimilate this natural, vital energy.
3. Almonds
High in healthy fats and protein, as well as vitamin E, magnesium and potassium, almonds (especially raw almonds) are great for snacking. They also add crunch and flavor to salads, cereals and porridge. Pre- or post- workout, almonds provide the satiation and nutrition you need to keep you going!
4. Apples
Research has suggested that an apple can be more effective in providing a boost of energy than a cup of coffee! That’s because apples contain natural sugars. When eaten in their whole form, apples also contain fiber, which slows down the absorption of sugar, providing a slow, sustainable release of energy.
5. Lemons
Toxins are everywhere and a toxic overload can cause fatigue, acne and serious illnesses. But lemons can help you kick those babies to the curb and reclaim your energy—and your health. Renowned for their healing powers, lemons flush toxins, alkalize the blood and support the immune system and liver.
