My mother always used to tell me “eat your greens, they’re good for you!” It turns out, mother was more right than she could possibly know.
Eating one’s greens may be even more crucial for immune health than we previously thought, according to recent research which has discovered that an immune cell population essential for intestinal health may be controlled by leafy greens in the diet.
The immune cells, termed innate lymphoid cells (“ILCs”), are located in the lining of the digestive tract. They were discovered in 2013 by researchers at the Walter and Eliza Hall Institute of Molecular Research in Australia. 
Let me back-track a bit. Science has, for many years, divided the immune system into two types: innate and adaptive. Innate immunity is present at birth and does not require prior exposure to protect you against pathogens. Adaptive immunity only develops when you have been exposed to a pathogen, for instance chickenpox. Once exposed to a pathogen, your immune cells are able to recognize the invader and mount a defense against it. Adaptive immunity provides the SWAT team that identifies an invading enemy and makes the specific weapons (known as antibodies) needed to destroy it. The fascinating thing about ILCs is that they are neither innate nor adaptive, they sort of straddle the two.
ILCs include cells that have been known for decades, such as natural killer (NK) cells and lymphoid tissue-inducer (LTi) cells. NK cells are key in protecting us from cancer as they recognize a huge array of tumor cells and cancer stem cells and help to eliminate them through cytotoxicity and the production of cytokines. Other ILCs are found mainly in the mucosal lining of the gut and in other mucosal-associated lymphoid tissues, where they work hard to protect us from pathogens.
The 2013 research  discovered that a gene called T-bet is essential for producing these all-important ILCs. Going back to the subject of eating greens, they found that the gene responds to signals in the food we eat. They discovered that T-bet is the key gene that tells precursor cells to develop into ILCs. It does this in response to signals from the food we eat and to the presence of bacteria in the gut.
Here’s how it works. Apparently proteins in green leafy and cruciferous vegetables interact with a cell surface receptor that switches on T-bet. Researchers think that the proteins in leafy greens may be part of the same signaling pathway used by T-bet to produce ILCs.
These researchers were excited about the discovery because it has been exceedingly difficult to isolate or produce ILCs. So finding out that something as simple as leafy greens and cruciferous vegetables in the diet can turn on the gene responsible for making ILCs is noteworthy. Without eating greens and without T-bet, the body becomes more susceptible to bacterial infections and other diseases.
Beyond their role in immunity, ILCs are also found in adipose (fat) tissue where they regulate thermogenesis and prevent inflammation that may lead to metabolic syndrome, obesity-related asthma and insulin resistance. 
Interestingly, while reading all the research as I prepared to write this article, I came across any number of web articles that boldly denied that diet had any role to play in bolstering immunity – despite the vast amount of research that’s being published to the contrary. Some people live in an interesting land called DENIAL.

If you are struggling to overcome breast cancer, it is important to understand the role of a strong immune system. It is vital that you know that there are many powerful natural boosters for the immune system and that they enhance healing and help to stimulate the body’s natural healing defenses, making them perfect for use just prior to surgery, post-surgery and/or when you are going through chemotherapy and/or radiation.
The Importance Of A Strong Immune System
Once you are through with your treatments, building a strong immune system becomes even more important, to keep recurrences away. Your immune system is your first line of defense against not only pathogens, viruses, and bacteria, but cancer cells. If your immune system is under-reacting to an internal threat, cancer is often the result.
My Favorites To Build A Strong Immune System
Here’s my list of favorite supplements to build a strong immune system. Please don’t use everything listed below all at the same time. Always consult a health professional before embarking upon any regimen to get personalized recommendations for dosages and which of the following is best for you.
American ginseng (Panax quinquefolius) – a tonic herb, it can boost energy levels and decrease recovery time post-surgery.
Andrographis (Andrographis paniculata) – has been studied recently for its immune stimulating effects, as well as anti-inflammatory benefits. There’s a good article on it on the Memorial Sloan-Kettering Cancer Center website .
Ashwagandha (Withania somnifera) – an Ayurvedic herb useful for strengthening the immune system, it also combats the effects of stress, reduces anxiety and depression, and has anti-inflammatory benefits.
Astragalus (Astragalus membranaceus) – used for centuries by the Chinese, astragalus is a potent enhancer of the immune system.
Curcumin – a yellow pigment derived from the root spice turmeric, a powerful antioxidant. We have loads of research on its anti-cancer activity, and it decreases the levels of two enzymes in the body that cause inflammation. 
Echinacea (Echinacea angustifolia) – boosts the immune system by increasing production of white blood cells which help fight disease.
Essential oils – vast quantities of research now exist proving beyond a shadow of a doubt exactly how essential oils can be used to enhance immunity. Nearly every single essential oil contains phytochemicals (plant chemicals) that have research-backed anti-cancer and immune-stimulating properties. This is a vast subject, so if you’d like to know more about how to use essential oils – and which ones help the most, just subscribe to my newsletters. I share loads of great information in my free newsletters.
Glyconutrients – plant based and organic, these supply all eight of the simple sugars our cells require for proper communication, thus assisting with brain function, immune function, etc. When the cells are communicating better, everything starts working more optimally. What I like about them is that they help to create healthy stem cells. See my article Breast Cancer Stem Cells – Stopping Them In Their Tracks.
Goji or Wolfberry (Lyciumbarbarum) – unlike some herbs, this one has good research ,  which indicates its usefulness for increasing immunological responses. Best taken in a juice as it tends to preserve the polysaccharide content that dried fruit does not contain. The brands I love are Young Living’s NingXia Red (you can get that from me) and Freelife GoChi. Both taste amazing and are super easy to take and work the best for boosting immunity.
Goldenseal (Hydrastis canadensis)– a natural antibiotic, goldenseal contains the phytochemical berberine. It’s wonderful for helping to prevent and fight infections, it is a potent anti-inflammatory, helps boost white blood cells, and one 2010 study found that berberine inhibited the growth of two different types of breast cancer cells better than the chemo drug doxorubicine .
Green tea (Camellia sinensis) – contains potent antioxidant compounds that neutralize free radicals and prevent damage to the immune system. In addition, green tea stimulates the liver to secrete interferon, an immune compound that helps fight infection. To bolster immune function, drink 3 or more cups of organic green tea daily.
4Life Transfer Factors – specially formulated to help immune cells identify health threats and speed up the immune response to those threats. Transfer factors work by transferring immune memory and knowledge from one entity to another, a rather different approach to immune system support. I’ve taken these myself, have recommended them for hundreds of others and everyone loves them. You can get them from me. Contact me for more information.
It’s always a good idea to let your physician know exactly what you are taking in order to avoid any possible drug interactions.

The fact is, high insulin levels (which occur as a result of having lots of sugar in your diet) are associated with a 283% increased risk of breast cancer.
Sugar also depresses your immune system by 50-90% for up to 5 hours after consumption, something cancer patients absolutely cannot afford to have happen.
Cancer cells act much differently than normal cells. Normal cells need oxygen. Cancer cells despise oxygen. In fact, oxygen therapy is a favorite among many of the alternative clinics I have researched.
You see, cancer metabolizes through a process of fermentation. If you know anything about making wine, you’ll know that fermentation requires sugar.
Most natural therapists recommend a specific sort of diet – juicing organic vegetables and fruits is one of the best because the juices contain living enzymes and vitamins which will help to kill the cancer cells. Cancer cells like cooked foods over raw because cooking destroys enzymes and heat sensitive vitamins.

About Cancer and Emotions: Regret Lowers Your Immunity
The Huffington Post today added to our knowledge base about cancer and emotions and how interrelated they are.
According to a study done by Montreal’s Concordia University, the distressing feelings that come with experiencing regret can have a negative impact on your immune system.
Not too surprising! For myself, prior to my breast cancer diagnosis, I was all too aware that I was under a super-abundance of stress and not handling it well at all. Negative emotions like worry, fear, unremitting anger, an inability to forgive someone – quite simply, they are all toxic.
Experienced for long enough they can depress your immune system, the very thing you need to keep disease at bay or overcome it.
What to do about it? Well, quite simply you have to do what works for you. According to livescience.com, if you are able to get in touch with your emotions (name them), you can tame them, according to new research that covers the benefits of meditation and may help to discover why meditation works.
“Brain scans show that putting negative emotions into words calms the brain’s emotion center. That could explain meditation’s purported emotional benefits, because people who meditate often label their negative emotions in an effort to ‘let them go.’ Psychologists have long believed that people who talk about their feelings have more control over them, but they don’t know why it works.”
So you must do what works for you, whether it be talking with your psychiatrist, your best friend, or spending some time in reflective meditation. Don’t know how to meditate? Want some help? I’ve created a downloadable how-to-meditate course specifically for cancer patients.
