10 Ways to Lower Estrogen


This info is from a great article on managing estrogen load - 10 Ways to Lower Estrogen Toxic Load. It's especially pertinent to me because my breast cancer is hormone (estrogen and progesterone) receptor-positive, which means estrogen can help stimulate tumor growth. I took aromatase inhibitors for two and a half years (Letrozole and Anastrozole) which block the enzyme aromatase, which turns the hormone androgen into estrogen.  I stopped taking Anastrozole a few months ago, choosing a more natural route for keeping estrogen low and moving safely through my system.


Understand how estrogen is metabolized 

Estrogen is metabolized by the liver. The liver converts excess estrogens into compounds that can be excreted by the body. The catch is there are three pathways through which estrogen can be metabolized. One is a “toxic” pathway that is linked to cancer development, the second is unfavorable for health, and the third is more benign and preferable.

If your body can convert estrogens along what is called the 2­hydroxy pathway it will be healthier and you’ll decrease your cancer risk, whereas if your body converts along the 16­alpha­hydroxy pathway it will be at greater risk of cancer. Don’t worry about the chemical names of the pathways, just remember that the C­2 pathway is healthier and the C­16 pathway and the C­4 pathway are unfavorable. The solution is to nutritionally support conversion of estrogen along the C­2 pathway, which can be initiated by ensuring you have a healthy gut.   


10 Ways to Lower Estrogen Toxic Load  


1) Improve Gastrointestinal Health
Poor gastrointestinal health can inhibit excretion of unwanted estrogen from the body and promote its reabsorption. A healthy gut with dietary fiber in the form lignan, such as flaxseeds, can bind to estrogen in the digestive tract so that it will be excreted from the body. Dietary fiber also reduces the amount of an enzyme (called B­glucouronidase) that uncouples or breaks apart bound estrogen that is on its way out of the body. When the estrogen breaks free in the large intestine, it re­enters circulation and is not removed from the body. This is a bad situation.

The solution is to eat adequate fiber and include lignans in the diet, including flax, leafy greens, and bran (oat, rye, barley). Eating plenty of probiotic foods or taking a probiotic is essential because it will increase the “good bacteria” in the gut and support neurotransmitter function.

2) Improve Diet With Low Carb, High­Protein, Omega­3 Fats
To avoid excess estrogen, you need to manage insulin because doing so is better for body composition, and persistently high insulin produces a poor endocrine profile that can inhibit estrogen metabolism. Getting your carbs from vegetable and fruit sources will provide the lignans and fiber needed for gut health and increase antioxidant levels, which can abolish free radicals that produced by estrogen that goes down the C­16 pathway. Omega­3 fats, which are found in fish, have been shown to promote the C­2 pathway over the 16 pathway, particularly EPA omega­3 fatty acids. On the flip side, diets low in omega­3s have resulted in estrogen being metabolized primarily through the C­16 pathway.

A high­ protein diet will produce a better body composition for most people. Plus, low protein diets have been shown to decrease activity of something called cytochrome P450 that metabolizes estrogen. The amino acids lysine and threonine have been shown to support liver function and since estrogen is metabolized by the liver, it is thought that these proteins can help get rid of estrogen from the body. Lysine and threonine are found in meat, fish, beans, eggs, and some seeds (sesame, fenugreek). Sesame seeds also provide fiber and fenugreek helps lower the insulin response to carbs, making both good additions to your diet.

3) Decrease Body Fat
The more fat you have, the more estrogen you’ll have because fat tissue increases levels of the aromatase enzyme that turns testosterone to estrogen. Decreasing body fat and building lean mass are key to cancer prevention and estrogen elimination. Another way to protect the tissues from circulating estrogen is to keep it bound to sex hormone binding globulin (SHBG). When it is bound to SHBG, estrogen is not available to bind with cellular receptors and won’t have its estrogenic impact. Flaxseed hulls are especially good at increasing SHBG (as well as inhibiting aromatase).

4) Use Phytoestrogens To Promote the C­2 Pathway
Include foods with phytoestrogens in your diet because they will take natural and chemical estrogens out of play in the body. Phytoestrogens are plant ­based compounds that can bind to estrogen receptors, but they have about 1/1000th of the effect on the body as real or chemical estrogen. When phytoestrogens bind to estrogen receptors they basically take up the parking sport of the true estrogen, and keep it from exerting its effect.

Lignans and isoflavones are the main phytoestrogens, and in addition to binding with estrogen receptors, they can increase SHBG levels (protects the body by binding to estrogen), decrease aromatase (prevents testosterone turning into estrogen), and shift metabolism of estrogen away from the C­16 pathway to the C­2 pathway (the safer pathway). The best phytoestrogens to include in the diet are flax, sesame, leafy greens, kudzu, alfalfa, clover, licorice root, and legumes.

5) Block Aromatase and Stop Testosterone From Turning into Estrogen
Blocking aromatase is key for getting rid of estrogen because it plays the main role in producing estrogen in men. If aromatase is present, there are two chances for estrogen to be produced in the body. First, the hormone androstenedione will be turned into testosterone unless aromatase is present in which case it will be turned into estrogen. Then, aromatase will turn testosterone into estrogen as well.

Nutrients that have a proven effect on aromatase include selenium, melatonin, zinc, green tea, and citrus flavonones—substances found in orange and grapefruit rinds along with tomato skins.

6) Improve Estrogen Metabolism By Promoting the C­2 Pathway
Promoting the C­2 pathway of estrogen metabolism is probably the most important thing you can do to prevent cancer. The first step of estrogen elimination is for enzymes to initiate metabolism by joining the estrogen molecule. This will happen at either the 2­carbon position or the 16­carbon position of the molecule, which determines the pathway the estrogen will head down. The C­2 pathway produces very weak estrogenic activity and is termed “good” estrogen. In contrast, the C­16 pathway produces robust estrogenic activity and promotes tissue damage that leads to cancer.

Key nutrients for supporting the C­2 pathway are EPA fish oils, phytoestrogens, and of special importance, B vitamins and a substance called DIM. The B vitamins, particularly B6, B12, and folic acid promote the C­2 pathway. B6 is also known to decrease gene activity once estrogen is bound to a receptor, meaning this vitamin can inhibit cell damage and cancer development. DIM is a compound found in cruciferous vegetables such as broccoli and cauliflower. It is often taken in supplement form because you would need to eat large quantities of these vegetables daily in order to provide sufficient DIM to have an effect on estrogen elimination.

7) Ensure Complete Elimination of Estrogen
Once you shift your estrogen elimination to the C­2 pathway you have to make sure it gets excreted from the body. Two things can happen along the way out that cause big problems. First, estrogen that is heading down the C­2 pathway can be easily turned into something called quinones, which are “highly reactive” and can damage DNA and cause cancer. In order to avoid the production of quinones you must have adequate amounts of two nutrients—magnesium and SAMe. This process of metabolizing estrogen to avoid quinones is called methylation and is the first place that things can go wrong on the estrogen elimination pathway.

As estrogen is heading out of the intestine, it needs to be bound to glucuronic acid, but there is a “bad” intestinal bacteria that contains an enzyme that breaks estrogen apart from the glucuronic acid. This is the second place estrogen detoxification can go wrong. When the “bad” bacteria, called glucouronidase, uncouples the bond between estrogen and glucuronic acid, estrogen re­enters circulation, effectively raising estrogen levels in the body and damaging tissue. To avoid this, you need a healthy gut, which you can get by supporting the probiotic bacteria in your gut and eating lots of fiber and lignans.

8) Supplement With Essential Nutrients
To review, the essential nutrients to help metabolize estrogen are the B vitamins, zinc, omega­3 fish oils, DIM (nutrient found in cruciferous vegetables), green tea, magnesium, selenium, and melatonin.
Vitamin E is another potent antioxidant that aids estrogen elimination. Low vitamin E is associated with elevated estrogen and it has been shown to inhibit the growth of breast and prostate cancer cells.
  
9) Watch What You Drink
Alcohol increases estrogen levels in men and women, and it has been shown to decrease testosterone as well. For optimal estrogen metabolism, it's recommended that you eliminate all alcohol besides certain red wine. Sardinian and Spanish wines are rich in antioxidants that help remove estrogens. Other good choices are Pinot and Merlot.  

10) Limit Chemical Estrogen Exposure
Avoiding chemical estrogens is one of the most important strategies for preventing cancer and protecting yourself. If you were able to have no contact with chemical estrogens, and you had good nutrition, a lean body composition, and a large proportion of muscle mass, it is very unlikely you’d have excess estrogen or be at risk of cancer. Unfortunately, chemical estrogens are everywhere. Because we cannot completely avoid contact with chemical estrogens, the reality is that you have to take responsibility for eliminating estrogen from your body and the bodies of your loved ones.

A better way to make decisions about your cancer treatment

Very glad to hear that shared decision-making is gaining traction. This is the way I prefer to work with my oncologist. Here's an overview from the American Cancer Society http://www.cancer.org/treatment/findingandpayingfortreatment/understandingfinancialandlegalmatters/informedconsent/informed-consent-shared-decision-making
Shared decision-making is a newer way of talking about treatment and treatment decisions, and some doctors are using it. It works like this: the doctor gives the patient information about the pros and cons of all the treatment options, including no treatment. This often means “homework” for the patient, such as reading, looking at DVDs, or sifting through other types of information. The patient tells the doctor about factors (preferences, health problems, home conditions, and such) that might make each treatment option better or worse than the others. Together, the patient and doctor decide which treatment is best for the patient. Or they may decide on something else, such as waiting for further developments before choosing a treatment. 
This is quite different from just saying “yes” or “no” to the treatment the doctor offers you. It may mean that you must take in more information, ask more questions, share more about yourself, and take more time to sort through your options together.This type of decision-making is especially helpful when there is no single “best” treatment option. For many people, the extra effort is worth it – they feel more certain that they made the best treatment choice for themselves. But for others, it may be too much or feel overwhelming (see the next section called “What if I want my doctor to make the decisions about my care…?). 
It’s OK to tell the doctor that you don’t want to share decision-making. But if you do want this kind of input let your doctor know. Be sure that you understand all the reasonable options for your situation, and go over them with your doctor. See the section called “What questions should I ask during informed consent?” to get some ideas of what to ask about each treatment option. Keep in mind that your doctor may not have as much information about some treatments as others, and you may need to get a second opinion to get a more complete picture.

Keeping glucose levels low is key to starving cancer


In 1924, Dr. Otto Warburg won a Nobel Prize for his hypothesis that cancer cells had a fundamentally different energy metabolism compared to healthy cells. Dr. Warburg showed that cancer cells exhibited a preference for the utilization of sugar (glucose) as a fuel, even when the oxygen that normal cells use for energy creation was available. He wrote:
“Cancer, above all other diseases, has countless secondary causes. But, even for cancer, there is only one prime cause. Summarized in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar.”
Stands to reason then, that step one of any cancer protocol would be to limit sugar, right?  Sadly, I have never once heard an oncologist mention this. What's worse, is most oncology centers have a big bowl of candy at the counter and a vending machine stocked with cookies, candy and high carb snacks. I know the people in these centers are well meaning. "It's comfort food" I heard one of them say, as I bit my tongue. "No, it's killer food" is what I wanted to say.

When I started my journey, I cut out all sweets, stopped drinking (yes that's sugar), went gluten-free, and limited meats, diary and other foods that contributed to an acidic environment. An acidic environment is a low oxygen environment. More on the pH connection later.

What I didn't realize initially was that it wasn't that simple. I had limited carbs, and had better carbs, but still didn't have the right protein-fat-cab balance. More research suggested that a ketogenic diet was a better fit.

A ketogenic diet calls for minimizing carbohydrates and replacing them with healthy fats and moderate amounts of high-quality protein. Paleo, Ideal Protein, Zone and Atkins are similar type diets, but tend to focus more on the protein, and less on the fat element and overall balance. Respectfully most diets are about weight loss, so fats are limited. With cancer, we're not as concerned about the calories.

The ketogenic diet gets its name from ketones, substances made when the body breaks down fat for energy. Fat, like sugar, is a source of energy. Unfortunately, the body goes to the glucose fuel first and only goes to ketones in long term storage when glucose is not available.

Here's the bottom line - if cancer cells don't get sugar, they die. But its not just about limiting sugar in your diet. It's about understanding the role of carbohydrates and their conversion to sugar and the importance of the protein-fat-carb balance. Getting the body to use ketones as a fuel source is an important part of the process.

How staring at your dog helps you beat cancer

A recent NY Times article The look of love is in the dog's eyes talks about how staring into the eyes of your dog causes the release of the hormone oxytocin in both you and the dog.
Japanese researchers found that dogs who trained a long gaze on their owners had elevated levels of oxytocin, a hormone produced in the brain that is associated with nurturing and attachment, similar to the feel-good feedback that bolsters bonding between parent and child. After receiving those long gazes, the owners’ levels of oxytocin increased, too.
Combine that with studies that show how oxytocin inhibits proliferation of cancer cells and you can see why I've added regular stare fests with Eva to my cancer protocol.

Truth is I was already staring at Eva pretty regularly, but with a different intent. She cries when she's hungry, which is pretty much all the time, and the way I get her to stop is just to stare at her.

I can't imagine life without a dog, much less trying to beat a life-threatening disease without the support of pets. It pleases me to no end that I now have scientific proof of the value of our stare fests.

Here are links to the oxytocin and cancer stories:

What I've Learned From Cancer

I’ve learned that the best cure is the one you believe in the most.

I’ve learned that people get sick for different reasons and they heal in different ways. 

I’ve learned there’s no such thing as false hope. 

I’ve learned that having a dog snuggle up beside you is the best medicine there is.

I’ve learned that a life-threatening disease is the fastest way to find out what your spouse is made of (though I don’t recommend it as a testing device).

I’ve learned that sometimes the people who are there for you aren’t always the ones you expect to be there.

I’ve learned to forgive those who weren’t there for me, understanding that people often don’t know what to say or do and many are afraid.

I’ve learned that a sick child brings out the best in parents, no matter what the age of the child or parent, and that cancer has a way of instantly erasing all the crap between you that once seemed important.

I’ve learned that fathers love by fixing and mothers love by cooking and cleaning.

I’ve learned what fear and love look like as they run together on the faces of those who love you most.

I’ve learned that Nicki Giovanni was right – we are responsible for those we love and for those who love us.

I’ve learned about the immense power of the mind to heal the body and how much control over healing each of us really has.

I’ve learned the power of words….
-   How the word malignant can evoke fear in even the bravest among us.

-   How the body listens to every word you say, so its important not to use clich├ęs like “This is killing me.” 

-   How the words doctors use influence whether their patients live or die. When doctors tell their patients they’re going to die, they generally do.   

I’ve learned that your unconscious and your body are very aware of the mood of an operating room – that it makes a difference how the doctors feel - about you, about what they’re doing, and about the eventual outcome.  (And it seems to help to have Motown playing in the background).

I’ve learned the power of prayer and how it doesn’t matter how someone prays or even how well they know who they’re praying for – it just matters that they pray.

I’ve learned what it feels like to receive love and energy from other people, to actually feel it coming into your body – it is both electric and soothing at the same time.

I’ve learned that a big part of healing is letting go, getting rid of all toxins, both emotional and physical.

I’ve learned that we attract to us the experiences we need in order to learn and grow.

I’ve learned that you don’t have to get sick to grow spiritually and emotionally (but it seems to work out that way for many of us).
  
I’ve learned there is no single explanation as to why I got cancer.  It wasn’t the mosquito truck or not having children, or smoking or drinking or too many cheeseburgers, or lack of nurturing, a bad marriage or a stressful job.  It is all of these things and none of them. 

I’ve learned that avoiding stress is very stressful.

I’ve learned that it’s true – shit happens.  It’s equally true that when it does, those of us looking for the pony amongst the shit are the ones most likely to survive.

I’ve learned that getting a new set of breasts is kind of like getting a new car.  You start seeing similar breasts all around you, when before you hadn’t noticed them at all.

I’ve learned that it’s not nice to make fun of middle-aged women who have round perky breasts because they might have had breast cancer.

I’ve learned that it’s not nice to make fun of middle-aged women who have round, perky breasts whether they’ve had cancer or not.

I learned how to ignore the drainage tubes sewn into my skin and the douche bags flapping from my chest.  I learned how to conceal the extra baggage under a stylish layered ensemble.  I learned how to accessorize cancer. 

I’ve learned that whenever possible, you should schedule mastectomies in the winter months because it makes for easier hiding of the afore mentioned drainage system.

I’ve learned it’s better to schedule hospital stays during holidays because you have a better choice of rooms.

I wrote this in 2001 when I ventured through cancerville the first time. Found it today and thought it would make a nice post. I'll follow up with new learnings soon.
