History

The Divine Origin of Cocoa

Mayan and Aztec creation story: discovered in the Mountain of Sustenance by the god Plumed Serpent (Quetzalcoatl) Quetzalcoatl was eventually poisoned by 3 sorcerers and became insane.

He burned down the houses, most of the cocoa trees, and disappeared on a raft into the open sea It was said he would return again with a cured and open mind in 1519 AD

The rest of the story...

Medicinal Uses

16th to 20th century manuscripts from Europe list >100 medicinal uses for cocoa of which 3 roles remain consistent: 1) To treat emaciated patients to gain weight 2) To stimulate nervous systems of apathetic, exhausted or feeble patients 3) To improve digestion and elimination Also popular treatment for: *Anemia *Kidney Complaints *Mental Fatigue *Fever *Indigestion *Hemorrhoids *Abdominal Pain *Vaginal Irritation *Decreased appetite *Tormented Thinking *Worms *Decreased sexual desire

Flavanol Content of Cocoa Powder

Health Effects

- Improves endothelial function in patients with coronary artery disease (Heiss et al. Journal of the American College of Cartiology, 2010) - Blood pressure lowering capacity (Desch et al. American Journal of Hypertension 2010) - Anti- hypertensive effects (Taubert et al. JAMA 2003) - Anti- thrombotic and anti-atherogenic effects (Holt et al. JAMA 2002; Mathur et al. J Nutr 2002) - Reduce peripheral vascular resistance and improve cardiovascular benefits (Heiss et al, JAMA 2003) Mars, Inc., plans to seek a health claim for chocolate from the Food and Drug Administration (FDA) in the next few years based on research they sponsored regarding the potential role of cocoa

Polyphenol Content

Total polyphenol content in chocolate products depends on the amount of non-fat cocoa solids (NFCS) (ie NOT including cocoa butter) Polyphenol content: #1 Cocoa powder #2 Unsweetened baking chocolate (100% Cacao) #3 Dark chocolate #4 Milk chocolate #5 Chocolate syrup

Cocoa Processing

• Cocoa is the fermented and dried bean from the fruit of the cacao tree (

Theobroma cacao

).

• Beans undergo fermentation, drying, and roasting o Fermentation breaks down cells and diffuses poly phenols • Nibs may undergo

alkalization

(ie. Dutching with potassium carbonate) to develop flavour and colour.

Cocoa Processing (Cont'd)

Nibs are milled to create COCOA LIQUOR particles suspended in cocoa butter) (cocoa • Liquor is pressed to extract the COCOA BUTTER • • Cocoa mass is dried into COCOA POWDER or Cocoa liquor is combined with more cocoa butter and other ingredients to make CHOCOLATE • WHITE CHOCOLATE is cocoa butter without cocoa liquor or cocoa powder

What does "% Cacao" mean?

Percent (%) cacao content refers everything derived from the cocoa bean % Cacao Content = Cocoa liquor + cocoa butter + cocoa powder For example, in Ghirardelli's 60% Cacao Dark Chocolate, the 60% cacao content is made up of cocoa butter and chocolate liquor with the remaining 40% made up of sugar, vanilla, and other ingredients.

Bioavailability

Percent of Non-fat Cocoa Solids:

Biggest determinant of polyphenol content.

Alkalinization, a.k.a "Dutching":

Dramatically decreases flavonoid content in cocoa powder.

Raw cocoa (under fermented/under-roasted):

higher polyphenol content but may be bitter or astringent. Generally never heated over 118 degrees.

Region of Origin:

Phenolic content varies based on region of origin but beans often blended in finished product.

Take Home Messages

Choose "natural" or "natural process" cocoa powder

Choose dark chocolate with the highest % cacao (ie the least amount of sugar and milk added)

Raw products have higher polyphenol content but may be more bitter or astringent

Cacao's Nutritional Brags

Magnesium

: #1 source of magnesium of any food. Works to support the heart, boost mental focus, and relieve constipation. Also linked with a lessening of PMS symptoms. Primary reason women crave chocolate during their monthly cycle?

Iron:

Raw cacao contains approximately 314% of RDA of iron per 1 ounce (28 g) serving. Works to carry oxygen from the lungs to every part of the body.

Antioxidants:

polyphenols, catechins, and epicatechins. By weight, more antioxidants than red wine, blueberries, acai, pomegranate, and goji berries COMBINED.

Others:

Copper, Manganese, Zinc. Omega 6 fatty acids.

Cacao Chemicals

Tryptophan: serotonin/melatonin synthesis Phenethylamine: "Love chemical" Anandamide: "Bliss chemical" Theobromine: Aphrodisiac?

vasodilation.

Marketplace

Cacao nibs:

Roasted: specialty chocolate/grocery stores. Raw varieties: online •

Cocoa powder:

Dutch/Alkalized widely available. Natural: mostly specialty stores/online •

Dark Chocolate:

Cacao Nibs Trail Mix Recipe

1 cup dried cranberries 1 cup cacao nibs 1 cup raw cashews 1 cup raw pumpkin seeds Combine all ingredients in a big bowl. Store trail mix in an airtight container. Enjoy !

Original recipe, B. Beasley, 2012

RP's Raw Brownies

1 cup walnuts 1 cup dates (pitted) 1/4 cup cacao powder Process in food processor for about 30 seconds, or until well combined. Mixture should be dry and chunky. Press mixture into a small springform pan. Refrigerate until a knife can be inserted and it isn't too sticky when removed.

Cut into pieces, then pop into a ziplock baggie and freeze. The brownies can be eaten fresh, from the fridge or from the freezer, but they won't last long!

Discuss...

Would you recommend cocoa to a client with high blood pressure or CVD? Why/why not? If so, how would you incorporate it into their diet?
