For those who can’t grow pomegranates, consider sumac instead

Sumac is a shrub like tree or a tree like shrub that is an invasive plant in many areas. Types that have white berry clusters should be avoided as the white berries are poisonous but the types with clusters of red berry like seeds are safe to consume when made into a tea and they may be dried and ground into a spice. Native Americans use them in a lemonade like beverage and they are ground into a spice which is used in many Middle Eastern dishes and as a table condiment to sprinkle on foods to individual taste. The ground Sumac is mixed with salt or available plain in shaker bottles and is mixed with a few other spices in the blend called za’atar (sesame seed, salt, and thyme or hyssop).

Some of the phytonutrient content and medicinal properties  of edible sumac are similar to those found in pomegranate and may be associated with the bright red pigmentation. The botanical name for Sumac , ‘Rhus,’ translated as a foreign word means ‘red.’ Some people may be allergic skin reactions from touching the plant in nature (1) and as a more concentrated tea it has diuretic properties, which can have health benefits to help remove toxins if plenty of additional water is also consumed to prevent dehydration. (2)

Sumac is used medicinally in Arab countries. Studies on sumac extracts to date have indicated that the plant may be a source of bioproducts with the following bioactivities: antifibrogenic, antifungal, anti-inflammatory, antimalarial, antimicrobial, antimutagenic, antioxidant, antithrombin, antitumorigenic, antiviral, cytotoxic, hypoglycaemic and leukopenic (Rayne and Mazza, 2007).” (1)

The lemonade like flavor would be from the terpene limonene and possibly other terpenes found in the plant. Anthocyanins likely give it some of the bright color. It also contains tannins primarily in the form of gallotannins, which are similar to the elligatannins/ellagic acid found in pomegranate, (3), and other aldehydes and beneficial acids that give it tartness including vitamin C – ascorbic acid. (1) Eating a large enough amount on a regular basis may be important for the health benefits from phytonutrients. Research with elligatannins has found them helpful for cancer prevention and somewhat for treatment (4) but a recent study that used a small dose, 900 mg of pomegranate extract per day, found some changes in important genes but not conclusive health benefits. (5) Research on tumor inhibiting properties of sumac found it beneficial during early stages when the tumor is developing rather than as a treatment after it was formed (animal study). (6) Animal based trials in more recent research that found benefits using pomegranate extract used doses that would be equivalent to larger doses, 1 to 10 grams/kilogram body weight per day. The study and amounts used are discussed in this post and the link is in this earlier post. A beneficial substance that we have to make for ourselves, Nrf2 may be involved. Tannins, anthocyanins, and aldehydes were all mentioned as being helpful for helping promote our own body’s ability to produce more Nrf2. The gallic acid (related chemically to the gallotannins, the mango fruit is also a source (8)) is mentioned to help induce apoptosis in cancer cells (cell death) in an article discussing the role of oxidative stress in cancer treatment. (7)

“Gallic acid (3,4,5-trihydroxybenzoic acid, GA), a polyhydroxy phenolic compound, is abundant in natural plants such as gallnut, grapes, sumac, oak bark, green tea apple peels, grapes, strawberries, pineapples, bananas, lemons, and in red and white wine. Its antioxidative DNA-damage action has been well documented []. However, gallic acid induces apoptosis in several cancer cell lines by increasing ROS level and GSH depletion [].” (7)

That excerpt is from a section titled: 5.1. Anticancer ROS-Generating Compounds from Natural Origin(7), which also contains information on other phytonutrients and foods that contain them that have been found beneficial for preventing or treating cancer or reducing oxidative stress.

I bought some dried sumac prepared for table use but chose a brand without salt added to it so I could use as much as I want without having to be concerned about adding too much salt. The aroma and flavor are good and the color is very pretty, slightly more purplish than paprika but similar in the bright addition it makes when sprinkled on the surface of a food. It was $3.99 for a 9.33 ounce bottle at a Middle Eastern foods grocery store.

Phytonutrients with bright colors often seem to be associated with health benefits but that doesn’t mean all wild berries or plants are edible. Read guides and know what you’re harvesting before eating it – and avoid private property and nature preserves where it might be illegal to pick anything.

They are so common in some areas that I happen to have picture taken on a recent walk. A discussion with more detail and a close up image taken during late summer is available here: The ‘Lemonade Tree’: It’s Time to Harvest Sumac, EdibleEastEnd.com. (2)

Ellagitannins and red raspberries

Prior to the research on pomegranates and ellagitannins research was being performed on the use of red raspberries for their health and anticancer benefits. The summary points are that the whole fruit, the mixture of a variety of phytonutrients provides the benefits and that an isolated singe phytonutrient may be less bioavailable and less bioactive – less chemically likely to provide benefits as the mixture of phytonutrients that the whole food provides. An article from 2001 discusses this in more detail and mentions that early work on pomegranates suggested they would be an even better source of the group of ellagitannins and other polyphenols.

The compounds when working together within the body seem to help make cancer cells stop dividing and start dying by apoptosis like normal cells would – and without having any toxic effects on other normal healthy cells. The ellagitannins and other phytonutrients in red raspberries also seemed to prevent precancerous cells from becoming cancerous – dividing at above average rate of growth.

Other health benefits of the whole fruit used as a fruit puree equivalent to eating one cup of red raspberries per day, providing 40 mg of ellagitannins, included:

“European medical studies also demonstrate that red raspberry ellagitannins lower the incidence of birth defects, promote wound healing, reduce heart disease, and may reduce or reverse chemically induced liver fibrosis. In addition, the ellagic acid produced from the ellagitannins has anti-bacterial and anti-viral properties.”

Ellagitannins and pomegranates was a discussion begun in a previous post: Pomegranate polyphenols and Microglia M2 Activation. I didn’t include the information in my summary but one of the links mentions that whole pomegranate juice / juice made with the peel / provides about 2 grams per liter of ellagitannins which would be many times more than 40 milligrams. Two grams would be 2000 milligrams and a liter is slightly less than a quart which is four cups, so roughly the whole pomegranate juice/extract is providing 500 milligrams per cup. A cup of juice would be more concentrated, being a liquid, compared to a cup of loosely packed whole red raspberries with seeds and air space, so a cup of raspberry puree or red raspberry juice would likely provide more than 40 milligrams.

Black raspberries are a dark purple color were not mentioned in the 2001 article but a more recent study on cancer therapy from 2016 mentions them as a source of ellagic acid so they may have an equivalent amount of the beneficial phytonutrients.

Blueberries and blackberries and other berries are good sources of a variety of beneficial phytonutrients. Many types have the most prevalent phytonutrients listed and extraction methods that are typically used for commercial products are discussed in this research review: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5384171/

Pomegranate polyphenols and Microglia M2 activation

The short story is that pomegranate polyphenols activate a very strong positive defense mechanism against inflammation that may be less active in autism. Read more:

Pomegranate juice polyphenols induce a phenotypic switch in macrophage polarization favoring a M2 anti-inflammatory state. (1)

“Pomegranate juice given daily for 2 years to 40 prostate cancer patients with increasing PSA levels provides evidence for the possible utilization of a nontoxic option for prevention or delay of prostate carcinogenesis. It is remarkable that 85% of patients responded to pomegranate juice in this study.” Pomegranate Ellagitannins – Herbal Medicine, (4)

(Punicagilanin and other polyphenols from a group called ellagitannins are found in the pomegranate juice and more are available when the entire fruit is used to extract juice. The bioactive phytonutrients seem to start being excreted from the body within 12 hours based on clinical studies, so a daily intake would be required for consistent benefits. Pomegranate Ellagitannins – Herbal Medicine, (4))

The long story is best left to read on a website written by a doctor who is working with research on the role of endocannabinoids in autism, how they may be involved in the risk as well as treatment for patients with the condition.

  • Read more: What Glyphosate Does To Your Brain: (2), which is a continuation of an overview on the topic of the herbicide glyphosate, autism and an endogenous cannabinoid that acts on the CB2 receptors.
  • Read more: The Autism Brain, Glyphosate, and Super-Cannabinoid Production (3)
  • Glyphosate was originally produced as an antibiotic and mineral chelator and may affect many pathways in the body due to changes to enzyme and mineral access and due to its chemical similarity to an important amino acid, glycine, which can act as a brain neurotransmitter.

So the short story is our body needs endogenous cannabinoids to protect our brain and the brains of infants from inflammatory toxins and pomegranate polyphenols may be a substitute as well as the non-euphoric cannabinoid CBD which activates the CB2 receptors.

Other foods that also may provide some natural cannabinoids or polyphenols that affect the system beneficially may include the herb Rosemary, the spice Cardamom, and unrefined cocoa bean products such as dark chocolate and Baker’s Cocoa Powder or Baking Chocolate.
