Not getting enough green foods in your diet? Try these potent powders

You know the basics. All green foods are rich in chlorophyll, vitamins, minerals, and antioxidants-and they increase the body's alkaline balance. Beyond that, each green has its own unique set of characteristics. 

Here's a quick rundown of our favorites.

1. Wheat Grass

Wheat grass, one of the original super greens, is rich in superoxide dismutase (SOD), a powerful antioxidant produced by the body that's especially protective of blood vessels and heart health. It's also high in minerals, amino acids, and vitamins, especially vitamins A, C, and K. Studies show that wheat grass can treat ulcerative colitis and promote detoxification from bisphenol A (BPA), a toxic compound found in consumer products such as plastic water bottles. Don't be fooled by the name-most people with gluten sensitivities can tolerate wheat grass since it doesn't contain gluten.

2. Barley Grass

Barley grass has a nutrient profile that's very similar to wheat grass. Like wheat grass, it contains SOD; it's also high in iron, potassium, magnesium, and phosphorus. In one study, barley grass significantly reduced total and LDL cholesterol levels. In another study, 1.2 grams of barley grass capsules per day improved the health of people with diabetes.

3. Alfalfa

Alfalfa is especially high in minerals and trace minerals. Plus it contains coumarin, an anti-platelet substance that can help prevent blood clots and improve circulation. Alfalfa also contains phytoestrogens and may help decrease hot flashes and reduce menopausal discomfort. Note: If you have lupus or another autoimmune disorder, be careful about using alfalfa seeds, since they can worsen these conditions. Check with your health care provider first.

4. Chlorella

Chlorella, a member of the blue-green algae family, is a single-celled organism that's an estimated 4 billion years old. It's rich in protein and vitamins, especially vitamins A and B. Chlorella is considered the most alkaline of all the greens, and contains an exceptionally high concentration of chlorophyll. Several studies have suggested that chlorella can support immune function, protect against cancer and inflammation, boost energy and stamina, and treat fibromyalgia, hypertension, and ulcerative colitis.

5. Spirulina

Spirulina, also a single-celled member of the blue-green algae family, contains up to 70 percent protein by weight, with a complete amino acid profile. It's rich in B vitamins, especially B12, plus iodine, minerals, and gamma-linolenic acid (GLA)-a fatty acid that boosts brain and heart health and protects joints. Studies show that spirulina can help protect against neurodegenerative disorders, improve exercise performance and fat oxidation, strengthen immunity, increase the body's concentration of the antioxidant glutathione, boost energy, and help treat patients with HIV/AIDS. Spirulina is also regarded as a skin-enhancing supplement-many women swear it gives skin a healthy glow.

6. Matcha

Matcha, a relative newcomer to the green foods scene, is a very finely powdered green tea. Matcha is rich in epigallocatechin gallate (EGCG), a powerful antioxidant. Studies have also shown that green tea has antiatherosclerotic, antibacterial, anticancer, antidiabetic, antiobesity, and antiviral effects.
