"Modern research has identified several important and beneficial nutritional compounds in Noni. Studies have suggested an exciting finding: that Noni increases the efficacy of the immune system by stimulating white blood cells into “overdrive”. Polysaccharide compounds (6-D-glucopyranose pentaacetate), which are found in the fruit, are generally believed to increase the overall killing power of white blood cells. Also, Noni fruit is full of many powerful antioxidants and compounds already believed to promote wellness such as: selenium (skin elasticity, skin health), xeronine (cell structure health and regeneration), glycosides (defense against free radicals), scopoletin (anti-inflammatory properties), terpine (helps the body detoxify), limonene and anthraquinones (antiseptic properties particularly for people with compromised or inhibited immune systems).

Noni might be a good one for you to investigate. It's available as juice or powder that you can add to juice or foods. Noni is one of the recently-dubbed "superfoods" - natural/raw foods that offer a multitude of health-promoting benefits.
Here's another quote:
"Noni – This Polynesian fruit has been in the news for quite some time and all for the best possible reasons. People the world over have started acknowledging the benefits of the noni fruit and researchers are giving it the status of superfood. The noni fruit has a strong smell and taste and is not palatable at first, but it takes a bit of getting used to. However, regardless of its taste, the noni is one of the most wonderful gifts of nature as it is power packed with nutrients that can fight numerous diseases and has loads of other benefits for you as well:
* Noni is rich with antioxidants that fight free radicals effectively, keeping you younger and healthier
* Other compounds such as selenium help in keeping the skin glowing, fresh and healthy
* Then there’s xeronine which works wonders for your cell structure and helps in cell regeneration
* Glycosides fight free radicals while scopoletin has anti-inflammatory properties
* An exciting new study shows that noni helps stimulate the white blood cells and kick starts the immune system to work effectively
Noni can be consumed fresh although its juice is highly popular now. Of course, some of its efficacy is compromised when mixed with sugar, so if you happen to visit tropical islands make sure to blend the noni fruit with coconut water and chug it down because it’s an excellent and tasty way of consuming noni. Noni powders are also available that can be mixed with juices and smoothies. Noni leaves are also consumed in the form of tea."
