Phytochemicals in Plants: Immune-Boosting Goodness

While visiting a farmers market, I came across a booth that carried a variety of edible plants. I had never seen such beautiful and bold colors in all of my life, and the bouquet of smells was intoxicating. I found out that what makes these plants so gorgeous and healthy are phytochemicals.

Plants contain thousands of phytochemicals like lycopene, flavonoids, and others. Studies have found that these compounds may boost the immune system and potentially destroy cancer-forming cells.

Sources of Phytochemicals

These foods provide the basic nutritional benefits of vitamins and minerals. In addition, these foods have a secondary health benefit obtained through phytochemicals, which have been found to provide a defensive barrier against cellular damage.

  • Tomatoes are high in vitamin C and also contain the phytochemical lycopene, which may reduce the incidence of protstate cancer.
  • Citrus fruits like oranges, lemons, limes and grapefruits contain flavonoids, which may have an anti-cancer effect.
  • Many dark green leafy vegetables like spinach and collard greens contain lutein, found to protect the cells from damage.
  • Studies have found that isoflavones, saponins and phytoesterols, found in soybeans and legumes for example, might slow down the growth of tumors.

Ways to Get More Phytochemicals

It is true that availability and access to fresh fruits and vegetables are limited in some parts of the country, resulting in fruits and vegetables to be cost-prohibitive. However, there are a number of ways to increase the intake of these health-promoting foods without too much cost or effort. If the produce is out of season or expensive, then look to the frozen food section; there are a variety of delicious and wholesome choices.
