Is Processed Fructose a Poison?

Is Processed Fructose a Poison?

Monday, 02 September 2013 22:13

What is a poison? Well, interestingly, there are different theories as to what makes something a poison. But most of them go something like this:

"A dangerous chemical, natural or unnatural, enters the blood through the skin, gut or lungs and travels to the liver, the primary organ of detoxification."

The liver attempts to "detoxify" the chemical creating metabolites — sometimes the metabolites are less toxic and sometimes they're not — in order to excrete the chemical and any remnants of it out of the body.

So for us to believe that fructose is a poison, it needs to follow, in some respects, the pathway I just described — and I'll get to that soon.

But first, let's clarify something...
Is Blue Corn Healthy?

Is Blue Corn Healthy?

Anthocyanins are a type of plant-based antioxidant found in abundance but not exclusively in berries. Take, for instance, blue corn, which is regular yellow corn that has a high level of anthocyanins. The anthocyanins are actually what give it a bluish hue.

Fortunately, anthocyanins are good for you from any source, including corn. Just take a look at this short list of benefits that are commonly attributed to anthocyanins:

Enhance glucose metabolism and reduce glucose absorption
Induce cancer apoptosis (programmed cell death) in several cancer cell lines.
Metabolize toxins and inhibit DNA damage.
Inhibit inflammatory gene expression and reduce inflammation.
Reduce capillary permeability and fragility and boost nitric oxide.
Metabolize carcinogens.

So this is why I am interested in both blue corn and anthocyanins. See where I am headed now?
Warning: Chronic Inflammation Can Damage Your Heart & Health

Warning: Chronic Inflammation Can Damage Your Heart & Health

Wednesday, 31 July 2013 12:37

Inflammation is the way your body responds to a problem. Whether battling an infection or cancer, or healing from a bone fracture, your body needs to deliver powerful immune and repair cells to the impaired location through your bloodstream in order to fight and fix the problem.

Inflammation is really designed to be an acute process that gets in and out quickly. The longer the immune and repair cells stay in a location, the greater the chance they'll actually cause damage to surrounding healthy cells and tissues.

Chronic inflammation, simply put, is acute inflammation that did not resolve properly. The result is damage and disease. This is why we call chronic inflammation the common denominator of all age-related disorders.
The 250:250 Weight Loss Rule

The 250:250 Weight Loss Rule

Monday, 01 July 2013 21:52

I did a search on Google for weight loss, weight loss supplements and weight loss nutrients. You can only imagine how many web pages and products Google found. We’re talking millions of web pages and thousands of product pages. No kidding.

But here are my questions. Have we overly complicated weight loss and do we really need thousands of “miracle” fat burners? Well, I think we have complicated it too much and I don’t think we need thousands of products. Let me explain.
Heart Disease Risk Factors Your Doctor Won't Tell You About

Heart Disease Risk Factors Your Doctor Won't Tell You About

Modifying traditional heart disease risk factors is not enough to protect your heart. Many Americans continue to suffer from heart attacks and stroke despite receiving a clean bill of health from their doctors. So what are we missing?

Traditional medicine modifies just 6 risk factors — obesity, smoking, high LDL-cholesterol, low HDL-cholesterol, high triglycerides, and high blood sugar.  However, integrative and alternative doctors have come to recognize 11 additional risk factors.

Here are two additional risk factors to consider if you want to keep your heart healthy …

Red Cabbage is Good for Bad Nerves

Diabetic neuropathy results from two destructive processes caused by high blood sugar: oxidative stress and glycation. Here at Life Extension® we are always looking for innovative ways to help fight against the damaging effects of high blood sugar.

The latest discovery is found in almost every grocery store in the nation … red cabbage. Researchers at the United Arab Emirates University studied red cabbage extract’s protective action against oxidative stress. Their results are quite amazing.1

Diabetes was induced in male rats using a common laboratory technique (infusion of the chemical streptozotocin). Within 60 days, all of the rats infused with streptozotocin exhibited many symptoms of diabetes including loss of body weight, high blood sugar, kidney problems and nerve cell dysfunction.
The Health Benefits of Walnuts: A True 'Super Food'

The Health Benefits of Walnuts: A True 'Super Food'

Wednesday, 22 May 2013 16:39
The Greeks called the walnut “the nut of Jupiter,” fit for the gods. Native to Persia, walnuts now come from California, which has over 122,000 acres of walnut trees. The tree itself is very hardy and is 15 years old before reaching full production. The average tree produces for 45 years.

Walnuts are high in unsaturated, fatty acids, iron, and B vitamins. The oil in walnuts has a tendency to absorb strong odors, so they should be kept in cold storage. Manufacturers of syrup toppings, ice cream, candy, casseroles and baking products all rely on walnuts.

Although many nuts have proven to be really beneficial to your health, studies are showing that walnuts contain almost twice as many antioxidants as other nuts. And that’s not just an interesting statistic — all of those antioxidants really do your body a lot of good. Below, we’ll take a look at two big stand-out benefits of walnuts.
