How Green Smoothies Can Devastate Your Health

green smoothiesGreen smoothies are all the rage these days. Many people are drinking them every day or at least several times a week in an attempt to get healthy and “alkalize” the body.

Whenever I visit the cafe of my local healthfood store, there are usually several people in gym clothes lined up to order a green smoothie to sip after their workout.

Green smoothies are made by blending large amounts of raw leafy green vegetables with fruit to soften and sweeten the taste. Typical vegetables included in green smoothies are cruciferous vegetables like kale, broccoli, collard greens, maca (usually as a supplemental powder) as well as others like spinach, swiss chard, celery, and parsley.

Is the green smoothie fad a truly healthy habit over the long term? Or, could regular consumption of these seemingly healthy drinks contribute to serious health problems over time?

Raw Leafy Greens Contain High Oxalate Levels

Frequent consumption of large quantities of raw, leafy green vegetables as occurs when a person drinks green smoothies can be deceiving at first as a person will probably initially feel great after adopting this habit particularly if he or she is coming off a highly processed, nutrient poor diet.

The vegetables used in green smoothies are almost without exception high oxalate foods.  Over time, a high oxalate diet can contribute to some very serious health problems particularly if you are one of the 20% of people (1 in 5) that have a genetic tendency to produce oxalates or if you suffer from candida or other fungal challenge.   In those cases, a high oxalate diet can deal a devastating blow to health.

Oxalate Toxicity Not a New Problem

Humans have suffered the effects of oxalate toxicity since ancient times. A 2000 year old mummy from Chile was discovered through x-ray analysis to have an oxalate kidney stone about the size of a golf ball!

Oxalates can be deposited almost anywhere in the body and wherever they land, pain or worse is the result.

75-90% of kidney stones are oxalate related with 10-15% of Americans afflicted at some point during their lives. As the star shaped crystalline stones pass from the kidney, they cause pressure and pain in the bladder and urethra and can actually tear up the walls of the urinary tract.

Oxalate Stones Can Form in Any Tissue

Oxalate stones can show up in any body tissue including the brain and even the heart.

Crystals comprised of oxalates resemble shards of glass. They can become lodged in the heart causing tiny tears and damage to this vital muscle. With every single contraction, more damage is caused as the heart pumps life giving blood to the rest of the body.

Oxalate crystals which end up in the thyroid can cause thyroid disease by damaging thyroid tissue.

A frequent location for oxalates to end up is skeletal muscle which will cause pain with even normal movement and make exercise nearly impossible.  Dr. William Shaw, Director of The Great Plains Laboratory for Health, Nutrition and Metabolism who has studied oxalates extensively, is convinced that oxalate toxicity is a factor in fibromyalgia the pain of which can absolutely devastate a person’s life (1).

Vulvodynia – Painful Sex

Cases of women experiencing painful sex are on the rise with oxalates a possible culprit.

Vulvodynia, a condition causing pain in and around the vagina, is linked to oxalates deposited in this delicate reproductive tissue. Oxalate crystals are very acidic and they cause irritation, burning, and stinging sensations for affected women with an accompanying feeling of rawness whenever they engage in sexual relations.

Oxalates Are Fungal in Origin

A surprising finding is that oxalates are produced in large amounts by fungus.  Large stones have been found in the sinuses and lungs of people suffering from systemic fungal infections such as candida or Aspergillus.

Therefore, anyone who suffers from any sort of candida or other fungal challenge like fungus nails or dandruff would be wise to be very concerned about oxalate intake via the diet.

Consumption of green smoothies would not in any way contribute to improvement of health in these situations. The majority of people today suffer from gut imbalance and candida (yeast) issues caused by antibiotic and prescription drug use including the Pill. This renders a high oxalate diet which includes frequent green smoothies an unwise practice for virtually everyone.

Does Cooking Destroy Oxalates?

What about cooking the greens first? Would this reduce the risk of oxalate overload and make green smoothies safer?

Not really, because oxalates are extremely stable. While cooking high oxalate foods and discarding the cooking water does reduce the level of anti-nutrients, it remains quite high.

Green smoothies are usually consumed frequently by those who swear by them. As such, a light steaming of the veggies first would not make a significant difference over the long term if they are consumed regularly. If you consume green smoothies only occasionally, however, a light steaming is a good idea. This practice adds a degree of safety to the process.

Healthier Alternatives to Green Smoothies

The best course of action for health, then, is to opt out of the green smoothie diet fad. This is especially important if you have any sort of gut imbalance or candida issues.

If you enjoy green leafy vegetables, be smart about it and don’t overdo. Enjoy them in moderation in salads or cook them and carefully drain and discard leafy green cooking water. Never use it in soups and sauces! Be sure to serve cooked leafy greens with a healthy fats like butter (not margarine or any factory fats synthesized with rancid and/or GMO vegetable oils like Smart Balance) for maximum absorption of minerals.

Another option is to drink raw cultured vegetable juice or eat raw cultured vegetables. Not only will you get enhanced nutrition from the culturing process which adds enzymes and nutrients, but you will also get a beneficial and therapeutic dose of probiotics to help balance gut function and improve digestion.

Another option is to do shots of fresh, green wheatgrass juice. Wheatgrass juice is very low in oxalic acid. Here is a link to my favorite green juice recipe using wheatgrass and ginger that is totally safe to drink regularly.

What to do if a Green Smoothie Diet Has Already Harmed Your Health

Are you already are suffering from some of the ailments described in this article? Do you suspect a high oxalate diet which includes green smoothies or a daily spinach salad may be the cause? If so, stop this practice immediately and consult with a holistic physician. You will likely need professional assistance to guide you on the road to recovery. Ridding your body of oxalate crystals that are potentially irritating one or more of your body tissues is no simple task! It is advisable not to attempt this on your own.
