In Response To: FRUSTRATION???? (Alex)


1. Deflect isn't going to allow you to regularly consume avoids any more than a bullet-proof vest can't protect your head, arms or legs. It may have some value as a 'morning-after' pill, but beyond that I would not posit...

2. It is used to primarily repair lectin damage, typically by lowering the activity of lectins in the gut and blood. Some lectins are are not food derived (such as bacteria, Candida, pollen, or even our own immune systems) and dietary avoidance will not inhibit them.

3. One way this repair mechanism works is by 'prying off' lectins which have already adhered to cellular receptors, such as insulin. Since insulin blockage by dietary lectins has been linked to both insulin resistance and obesity, using DEFLECT can help accelerate weight reduction in diet-compliant individuals by speeding up the time it takes for the regeneration of new insulin receptors or the 'cleansing' of the old ones. This can take upwards of one year in some individuals who just follow the diet, and explains why some dieters do not see weight loss in the early stages of the program. It is because of this 'lectin-locking' function that many other diets (which do have accelerated weight loss in their early stages) cause their followers to lose muscle mass and fat -when what we want is to lose only the fat. If the weight loss in ER4YT is occasionally slow, at least it is healthy: Losing only body fat means that that a person's weight loss can sometimes be only 50% as rapid as other programs which are destroying muscle and fat. The problem is that muscle is hard to get back, and any drop in muscle mass results in a lower metabolic rate, leaving the dieter more likely to gain back the weight, but this time only in body fat.

4. Many lectins can amplify the effects of auto-immune disease, such as thyroiditis, rheumatoid arthritis, schleroderma, fibromylagia and pemphigus. Research shows that some of the lectins which can cause this may actually be manufactured by the body itself (serum lectins). By acting as sacrificial molecules, Deflect can block this action.

5. Many people with 'food sensitivities' or 'leaky gut' have a phenomena called 'active endocytosis' where prior lectin damage results in an intestinal absorption surface that actively scoops up macromolecules. Because these larger molecules are very antigenic, then tend to increase local inflammation and thus increase the leaky gut. Again, by acting like 'sacrifical molecules' Deflect can block this, while also inhibiting bacterial adhesion to the gut as well (bacteria use their own lectins to attach to the intestines) a secondary cause of leaky gut. The amino sugars in DEFLECT can also help prevent re-infection by H. pylorri and many gram-negative bacteria which cause bladder infections, by flooding their own lectin receptors, thereby preventing adhesion, the first step needed for infection.

6. The amino sugars in Deflect encourage healthy bowel flora, although they don not provide a source of flora themselves. These same amino sugars are healthy enhancers of joint gliding surface and synovia as well.

7. Cancer metastasis is in many ways similar to infection, as both require attachment in their early stages. There is some evidence that amino sugars can block metastasis to certain organs, such as the liver, which have their own lectins lining their inner surfaces.


The following information is from the North American Pharmacal product flyer:


North American Pharmacal® introduces its new DEFLECT™ line of dietary supplements designed by the distinguished naturopath Dr. Peter D’Adamo, author of the bestselling book Eat Right 4 Your Type.

DEFLECT™ products provide anti-adhesive therapy to lectin sensitive individuals. These ABO specific formulas block the effects of dietary lectins before they cause problems , by providing a source of free blocking carbohydrate.

What is lectin?

According to an old definition ‘lectins are carbohydrate-binding proteins or glycoproteins.’ William Boyd therefore coined the term lectin in 1954, deriving it from the Latin word legere meaning ‘to choose.’ Boyd was also the first researcher to identify the blood type specificity of many common dietary lectins.

Typically, lectins can bind to many of the carbohydrate antigens found in the gut and immune system, causing a variety of health problems. These can include intestinal dysbiosis, bowel hyperpermiability, immune dysfunction, food sensitivities and systemic inflammation. This is usually accomplished by direct agglutination of the target cells. Lectins can occur in very common foods in the diet, and the majority are specific for the carbohydrates of the ABO blood typing system. In one study, the edible parts of 29 of 88 foods tested, including common salad ingredients, fresh fruits, roasted nuts, and processed cereals were found to possess significant lectin-like activity as assessed by hemagglutination and bacterial agglutination assays. (2)

Several common lectins, in particular, wheat germ agglutinin, are known to bind to the insulin receptor and mimick the hormonal effects of insulin on adipose tissue, an under-appreciated action which can account for why individuals on high carbohydrate diets often have difficulty contolling their weight. Thus, lectin blocking is a safe and rational method for enhancing weight loss.

In the words of one lectin researcher:

“Most lectins in our diet are resistant to breakdown during gut passage and are bound and endocytosed by epithelial cells. These lectins are powerful exogenous growth factors for the small intestine, can induce dramatic shifts in its bacterial flora and interfere with its hormone secretion. In addition, lectins which are transported across the gut wall into the systemic circulation can modulate the body's hormone balance, metabolism and health. Although these physiological effects are mediated or reinforced by immune responses, they are primarily the result of the specific chemical reactivity of lectins with cell surface receptors of the gut.” (3)

What is DEFLECT?

DEFLECT is a natural product composed of ‘blocking sugars’ designed to interfere with the adherence of troublesome dietary lectins. Since many lectins are ABO blood type specific, there are 4 different DEFLECT formulas: one for each blood type. The blocking sugars in DEFLECT can be considered ‘sacrifical molecules’ that attach to carbohydrate receptors on the lectins, rendering them unable to bind to the cells of the body.

The DEFLECT formulas provide a source of free blocking amino sugars (blue) which bind and block lectins before they can attach to the cells.

Since each blood type is succeptible to lectins with different carbohydrate specificities, Dr. D’Adamo designed formulas to block lectins by using mono and poly saccharides specific for each blood type.

Situations where DEFLECT™ products may be indicated include:

• Carbohydrate intolerant individuals who typically gain weight on high carbohydrate diets.
• ‘Leaky Gut’ and intestinal dysbiosis.
• Food sensitivies.
• Individuals with a low inflammatory threshold.
