Cinnamon




Spice Up Your Holiday's with Cinnamon!

The strong smell of cinnamon is distinctive and has the power to take you right back to a Holiday memory or reminder of a favorite food. It once held such significance that wars were fought over it, it determined social and economic class and was also used as currency. It has even been said to have healing powers. So what is it about this Holiday spice that is so special?

What exactly is Cinnamon?

Cinnamon actually comes from a small evergreen tree native to Sri Lanka. True Cinnamon, or “Ceylon” Cinnamon is tough to find and most Cinnamon sold here in the United States is actually Cassia, a related spice. Cassia is also from a small evergreen tree but is native to China and Vietnam, and is obviously very similar to Ceylon Cinnamon. The powdered spice we recognize comes from the bark of those evergreen trees which provides us with a wonderful aromatic holiday flavor.

What are these “healing powers?”

The oils present in the bark are what hold the healing powers - cinnamaldehyde, cinnamyl acetate, and cinnamyl alcohol. Cinnamaldehyde, helps prevent over-clotting of our blood platelets. Too much clotting of the platelets can lead to inefficient blood flow in the body. It also helps to release arachadonic acid (a fatty acid in our bodies) which has an anti-inflammatory effect. Other components of the oil have been shown to stop bacterial growth, boost cognitive processing and have been used for warming effects in the body. Perhaps one of the greatest discoveries is cinnamon’s effect on blood sugar levels. Cinnamon actually slows the rate at which your stomach empties after meals, which in turn decreases or slows the rise of blood sugar levels. Recent studies, including US Agricultural Service and Journal of Clinical Nutrition, are showing that cinnamon helps to stimulate insulin receptors, helping to increase the cell’s ability to use glucose. This is particularly important in those with Type 2 Diabetes (23.6 Million Americans). Less than ½ teaspoon per day will reduce blood sugar levels in those with Type 2 Diabetes. Because of this effect on blood sugar levels, most people will find that cinnamon also cuts their cravings for sugar!

Cinnamon is also a very strong antioxidant. When measured against anise, ginger, licorice, mint, nutmeg and vanilla (all spices said to be strong antioxidants), cinnamon actually prevented oxidation more effectively than any of them! Mint was the 1st runner up.

Does Cinnamon have any calories?

Yes it does. Cinnamon contains about 6 calories per teaspoon. It has some fiber, iron and calcium and 2 teaspoons holds about 40% of the daily recommended intake of manganese!

So try starting your day off with some cinnamon tomorrow. Sprinkle a teaspoon or two in your oatmeal, breakfast shake or even in your cottage cheese!

Or you could try some Cinnamon Pumpkin Waffles!!

Ingredients:
1 cup whole wheat flour
1/4 cup wheat germ
1/3 cup white sugar
1 teaspoon ground cinnamon
1 teaspoon pumpkin pie spice
1/2 teaspoon ground nutmeg

1 tablespoon baking powder

3/4 cup milk
1/2 cup pumpkin puree
2 tablespoons melted butter
2 tablespoons olive oil
1/2 cup unsweetened applesauce
1 egg
1 egg white
1/2 cup chopped pecans

Directions:
1. Preheat a waffle iron according to manufacturer's instructions. Combine flour, wheat germ, sugar, cinnamon, pumpkin pie spice, nutmeg, salt, and baking powder in a bowl. Set aside.

2. Beat together milk, pumpkin puree, butter, oil, applesauce, whole egg, and egg white. Stir flour mixture into the pumpkin mixture along with the pecans.

3. Ladle the batter onto the preheated waffle iron. Cook the waffles until golden and crisp, 5 to 7 minutes. Makes 4 Servings.

Alcohol Part Two: Antioxidants

First, lets review what an "antioxidant" actually is.

"Anti” means “against, or opposed to” and “oxidant” refers to the process of oxidation (when a molecular process in the body causes an increase in oxygen). So an antioxidant is a molecule that slows or stops an increase in oxygen. Now normally we think of oxygen as a great thing - we need it to live! But increasing oxygen in certain chemical reactions can cause free-radicals (molecules with unpaired electrons) due to the transfer of electrons that happens. A free-radical can be highly reactive due to that unpaired electron, which can cause damage to our cells and leave them susceptible to disease.

Antioxidants go in and fill in that missing electron, making the free-radical whole again. So you can imagine with pollution in the air, chemicals and pesticides in the water we drink and food we eat, sun damage to our skin, there is a lot of cell damage that happens to our bodies that leave plenty of free-radicals running around. So, in a nutshell, antioxidants are very important to our daily lives, which is why you're hearing the word so often.

There are many different types of antioxidants. They are split into 2 groups - those that are soluble in water and those that are soluble in lipids (fats). This matters in the body because we have both liquids (blood, etc) and lipids (cell membranes, etc) which are in need of antioxidant activity.

The Antioxidant in Red Wine

The antioxidant that is found in Red Wine, the alcohol most commonly associated with antioxidants is called "Resveratrol" which is considered a polyphenol antioxidant (the term refers to the chemical structure) and Phytonutrient (chemical compounds that naturally occur in plants). Studies of resveratrol in mice/rats have shown anti-inflammatory effects, blood sugar lowering effects, and may combat obesity, cancer and cardiovascular disease. However, most of these studies have not been repeated in humans yet.

Resveratrol is found in the skin of grapes used to make wine. The reason red wine is said to be higher in resveratrol than white wine is because red wine is fermented with the skins longer than white wine. But guess what? You can just eat grapes and skip the whole fermenting thing and still get the resveratrol - hellloooooo.....

Peanuts, blueberries and cranberries also have resveratrol. Below are a few charts for comparison.


Content in wines and grape juice
Beverage Total resveratrol (mg/150mL)

Red Wines 0.30 - 1.07
Red grape juice 0.17 - 1.30
Rose Wines 0.06 - 0.53
Pinot Noir 0.06 - 0.30
White Wines 0.01 - 0.27




Content in selected foods
Food Serving Total resveratrol (mg)

Peanuts (raw) 1 c 0.01 - 0.26
Peanuts (boiled) 1 c 0.32 - 1.28
Peanut butter 1 c 0.04 - 0.13
Red grapes 1 c 0.24 - 1.25




Besides the antioxidants in wine, the alcohol itself does have effects on the body that can "help" certain things but mostly just temporarily. Alcohol thins the blood and also causes blood sugar levels to drop (more on that in Part Three). Which could look really good to someone who has thickening arterial walls due to plaque buildup or someone with pre-diabetes who runs high blood sugar levels. But those effects happen just while alcohol is in the body, and the negative effects outweigh the positive ones.


The moral of the story is this: if you currently drink alcohol, please do so in moderation or less. "Moderation" is defined as 1 drink per day for females and 2 drinks per day for males. A "drink" is 5oz of wine, 12oz of beer or 1.5oz (shot) of liquor. Now I honestly think that's pushing it towards too much...but those are the defined guidelines. Remember from the last blog post on alcohol that one drink per night can result in 10 lbs of weight gain per year...so "moderation" may not be what you need! In fact, when trying to lose weight, you should not drink alcohol AT ALL. And for those of you that don't drink but were considering picking it up due to the antioxidant value, don't. You can get antioxidants from plenty of other foods, without the toxins from the alcohol.

Antioxidants

Antioxidants

“Blueberries are good for you because they have lots of antioxidants.”
“…oh, I’ve heard that. What’s an antioxidant?”
“…umm, stuff that’s good for you that’s in blueberries…it like, helps you age slower…”
“Yeah but what is it? Is it like a vitamin or something?”
“…umm, I dunno…yeah probably.”

Ok, so I know lots of you have heard of “antioxidants” before, and we’ve all seen the word written all over boxes of food and bottled drinks and lord knows what else (clever marketers). But how many of you have heard someone tell you that they are good for you, and be able to explain what it actually is? I bet you’d have a similar conversation to the one above with half of Americans who preach antioxidants daily. I want you to start thinking of nutrition as science, because that’s exactly what it is, and when we think from a science angle – you have to keep asking why, how, what, where, etc.

Big, long scientific terms like “macronutrient”, “polyunsaturated”, “glycogenolysis” and “antioxidant” are really just big words for simple meanings. For instance, “macro” means “big” and “nutrient” refers obviously to the nutrition present – so a macronutrient is just a nutrient that we need in large quantities in our body. Similarly, “anti” means “against, or opposed to” and “oxidant” refers to the process of oxidation (when a molecular process in the body causes and increase in oxygen). So an antioxidant would be what? Something (a molecule) that stops the process of oxidation. See, learning isn’t so bad!

Ok, so we know that an antioxidant is a molecule that stops the process of oxidation. What’s the next question?

What is oxidation? And why do we need to stop it?
Oxidation is a chemical reaction that happens inside our bodies and outside our bodies daily. In the process, electrons are transferred, which increases the oxygen present. Some oxidation reactions can produce free-radicals, which are molecules with unpaired electrons. Since electrons are being moved from one substrate to another during oxidation, some can be left unpaired, causing the molecule or element to be highly reactive. These free-radicals running around can kick start a chain of events causing damage to cells in our body. Damaged cells inside the body are not good, and have been linked to chronic disease states and illness, including cancer.

What antioxidants do, is they go in and fill in that missing electron, making the free-radical whole again. So you can imagine with pollution in the air, chemicals and pesticides in the water we drink and food we eat, sun damage to our skin, there is a lot of cell damage that happens to our bodies that leave plenty of free-radicals running around. The point is, we need lots of antioxidants!

Where can you find antioxidants?
Tufts University did an ORAC analysis (Oxygen Radical Absorbance Capacity) on common fruits and veggies. Here are the top picks based on ORAC units per 100 grams (about 3.5 oz).

Fruits
Prunes -- 5570
Raisins -- 2830
Blueberries -- 2400
Blackberries -- 2036
Strawberries -- 1540
Raspberries -- 1220
Plums -- 949
Oranges -- 750
Red grapes -- 739
Cherries -- 670
Kiwi fruit -- 602
Grapefruit, pink -- 483

Veggies
Kale -- 11770
Spinach -- 11260
Brussels sprout -- 1980
Alfalfa sprouts -- 1930
Broccoli Flowers -- 1890
Beets -- 1840
Red bell pepper -- 1710
Onion -- 1450
Corn -- 1400
Eggplant -- 1390


Now, its not just the antioxidants in the foods that will help repair cell damage, but the combination of essential vitamins and minerals with antioxidants that will lead to an overall healthier life.

Go eat some antioxidants and enjoy!
