Blending vs. Juicing

A chapter from Victoria’s up-coming book “Green Smoothie Revolution”
After I published my first book about green smoothies, I have received many inquiries from my readers asking whether blending was preferable to juicing. I also heard that some nutritionists were concerned that blending might accelerate the oxidation of the food. I was very curious to find the answer for myself and decided to seriously research this question.

I conducted a simple experiment. I chose potatoes for my experiment because it is easy to observe the process of oxidation in potatoes. You probably remember an instance when you left a slice of raw potato on your cutting board and observed it turning brown within several minutes. That is why my grandmother used to put peeled potatoes in water, to prevent browning or oxidation.

First, I peeled two potatoes so that the color of their peel wouldn’t interfere with the results of my experiment. I then juiced one potato in a twin-gear juicer and blended the other one in a Vita Mix blender with one cup of water. I placed both cups of fluid on the table and took a photograph of them. I was taking photographs frequently for two days. The potato juice started to turn brown within a matter of minutes and became dark brown by the end of the first hour. The blended potato stayed almost white for two days. The top of both liquids, which was exposed to the air, turned dark almost instantly. I repeated this experiment three times with different kinds of potatoes and various shapes of glasses. The results were the same.

It was clear that the juiced potato oxidized much faster than the blended potato. Since I am not a professional scientist, I decided to seek the opinion of someone with the appropriate expertise. I went to the local university and consulted with Gregory T. Miller, professor of chemistry of Southern Oregon University. After researching this matter, he wrote the following:

The browning is the result of oxidation of specific biomolecules in the fruit or vegetable. My students study this in lab so I have some familiarity with the process (albeit they are studying the enzymatically regulated oxidation). My wife is also a winemaker and deals with oxidation of her juice/wine or a regular basis. I also possess a huge number of resources on the oxidation topic in the form of biochemistry, medical, and nutritional books. Here are my thoughts:espiratory tract ailments.

Many people believe that the blending process will cause increased oxidation due to thousands of tiny air bubbles getting mixed into the “juice”. This effectively increases the surface area of oxygen in the liquid and facilitates the oxidation process. However, in grapes at least, I have observed the opposite to be true. The blended grape stays a truer color much longer. I believe this observation in grapes to be a result of numerous antioxidants released as the grape is blended (breaks open more cells than juicing). I believe this is what you are seeing with the potato, as well.

Potatoes contain numerous antioxidants. This may come as a surprise to many people because of the pale color of many varietals. Among others, potatoes are rich sources of phenolics, flavonoids, carotenoids, and anthocyanins. The concentration of each vary with the type of potato. Since your potatoes are skinless (where the greatest concentration of the tyrosinase enzyme is located), I believe the blending process releases a much higher percentage of these antioxidants from the tissue than the juicing process.

It is also possible that, in many fruits and vegetables, the bulk of the fiber released during blending reduces the oxygen saturation in the solution but, if true, I think this is a secondary issue.

Now I understand why it is commonly advised to drink squeezed juice within minutes of making it, and why smoothies can stay fresh for two or three days in the fridge. Even though I can clearly see the many benefits of smoothies, I still don’t want to completely disregard juicing. One of the main advantages of juice is that it requires next to no digestion and can be absorbed and assimilated immediately into the bloodstream, allowing the digestive system to rest. This important quality of juice allows it to be used by people who suffer from severe nutritional deficiencies or have highly irritable digestive system. People with these conditions often cannot tolerate any fiber at all, and juice may provide invaluable nourishment for them. Later, when their health will improve, these people can switch to drinking smoothies.

I agree with Dr. Doug Graham that juices are a fractured food, which is missing an essential component—fiber. When we consume enough fiber, we take a load off of our organism by improving our elimination. Toxins often build up in the colon and fiber cleans them out. When most toxins have been removed by fiber, then the body has a greater ability to absorb nutrients, thus improving digestion. Humans could not live on juices alone, whereas green smoothies are a complete food.

If I don’t have a blender around me, I juice. One time I gave my blender to my brother because I thought that he needed it more than I. While waiting for my new Vita-mix, I was juicing greens because I could not live without them. While I was juicing, I quickly got tired by the limited variety of flavors, in addition to that, I noticed that I I felt hungrier and I had to add more salads to my menu, as juices were not as filling as smoothies. Contrary to that, smoothies are very filling; I can live on them for days, and even weeks. I know of people who have chosen to live on smoothies for several weeks or months with beneficial results. You will find the extraordinary story of Clent Manich’s green smoothie experiment further in this book.

Five Reasons to Eat Low Glycemic Index Foods

May 15, 2009 By 1 Comment

Glycemic is the concentration of glucose (sugar) in the bloodstream. In order for the body to function normally a fixed range of glycemia (70 to 100mg) is required. The Glycemic Index (called GI Index) is a method that ranks foods based on how fast they raise glycemia.

There is typically a range of low (55 or less), medium (56-69), and high (70-99) Glycemic Index foods. The problem with most people is that they tend towards the high end of the glycemic index.

A Low Glycemic Index diet is a good idea for many reasons.

1. Helps Weight Loss

Eating low Glycemic foods helps to lose and control weight. When the higher Glycemic foods are consumed the extra glucose is stored as fat. So low Glycemic foods help to keep that glucose balance in your body, normally keeping you from gaining weight.

2. Improves Diabetes Control

If you are a diabetic then eating low Glycemic foods is a good idea. A low Glycemic diet increases the body’s sensitivity to insulin and improves diabetes control.

3. Reduces Health Risks

The risk of heart disease and high cholesterol are reduced. When you consume high Glycemic foods which include fried foods, white bread, doughnuts, baked potatoes, carbonated beverages, and beer, you are putting your body at a greater risk of heart attack and stroke.

4. Provides Slow, Even Energy

Low Glycemic foods release their energy slowly to the body. This helps the body to have a more concise and constant supply of energy. This in turn prevents drastic fluctuation in blood-glucose levels helping you to avoid feeling of fatigue, fogginess, and instability.

5. Balances Your Appetite

You can lose weight and have a lower BMI eating low glycemic foods. People who eat a greater amount of high glycemic index foods on average have greater levels or body fat. Lower Glycemic Index foods (under 55) metabolize slower and keeps your appetite balanced. If your appetite is balanced you won’t eat a much and you will lose weight.

The foods you should focus on to maintain a low glycemic number include: kidney beans, whole wheat pasta, tofu, soy milk, plain yogurt, apples, pears, sweet potatoes, bean sprouts, and many other fruits and vegetables.

The medium glycemic index foods include: bananas, pineapples, popcorn, and oatmeal. These foods are not as bad as the high GI foods and are a better choice when you can’t get to the low GI foods.

As mentioned earlier, high GI foods include most fried foods, pitas, doughnuts, soda crackers, baked potatoes and even watermelon.

The consumption of lower Glycemic Index foods is a wise way to watch your weight, keep blood pressure and cholesterol levesl down, keep up your energy level so that you can work more effectively through the day and help you maintain a stronger healthier life. The fact that they are mostly whole foods makes them readily available and very easy to prepare and add to your daily diet.

Health is not a joke and every precaution should be taken to ensure that your health is as good as it can possibly be. With research, a properly balanced diet that includes foods low on the GI food list, and other smart eating tactics, you can be a healthier and happier you.

Nutrition, Whole Foods Help Curb Cravings

May 11, 2009 By 3 Comments

At the foundation of every craving is an unbalanced diet.

Cravings are a sign that either your body has become too dependent on a substance (like salt or sugar) or that your body is missing out on important nutrients.

When you fill up on empty calories and junk food, your body will feel like it still needs to eat because it hasn’t received any nutrients with your meals. That’s why one of the most effective ways to reduce your cravings is to eat a balanced diet.

A balanced diet full of whole, unprocessed foods gives your body exactly what it is looking for. When you receive the same kind of nutrients that are necessary for proper body functioning, you won’t have as many cravings. Reduced cravings means that you won’t overeat and you’ll naturally lose weight.

The first step is to get rid of any processed foods that are a regular part of your diet. Packaged foods that are processed in a factory have excess chemicals and are normally higher in fat and calories than whole foods. Eating a lot of these types of foods will leave your body wanting more of both the chemicals and food in general. When your diet relies on these type of foods, you will feel full but will literally be starving your body of nutrition.

Vitamins cannot replace the natural nutrients and minerals that are found in fresh, whole foods. In order to reduce your cravings and get back on track with eating better, you’ve got to shift your diet. One of the easiest ways to tell if you are eating right is to take notice of where you do most of your shopping at the grocery store. If you concentrate your shopping on the outside aisles, then you’re eating fresh, whole foods. Most processed foods are found in the center rows of a grocery store. Stick to the fresh fruits and vegetables, whole grain breads, meats (if you eat them) and you’ll see a reduction in cravings.

In addition to craving more food than you should eat, you may also experience cravings for food substances like salt or sugar. Unfortunately, with these additives the more you eat, the more your body wants them. In order to curb this craving, you’re going to need to take steps to remove them from your diet entirely.

It may be hard at first, and you’ll definitely go through a withdrawal period where you experience an intensification of your cravings. Increase your water intake, start an exercise program and keep eating healthfully. Chemical additives and excess sugar and salt can sometimes be hard food addictions to break. Commit yourself to eliminating these things from your diet for at least 2 weeks and you’ll see a big difference.

The best way to eliminate cravings from your life is to incorporate fresh, whole foods into your diet. Remove harmful substances from your diet and once you get over the initial withdrawal, your health will be better and you won’t experience cravings any longer.
