Brazil nuts can help your dog live longer!

Add a Brazil nut to your dog’s diet to help prevent cancer, the leading disease killer of dogs. Read about the critical cancer-fighting difference between the sodium selenite used in most dry dog foods and the selenomethionine found in Brazil nuts and other foods

 

A variety of fresh food is best for animals and humans

Human nutrition and lifestyle studies prove that we can improve the odds that we will live long, healthy lives.  It’s simple: Eat a variety of fresh, minimally-processed foods, especially fruits and vegetables. Stay lean, exercise often, and avoid toxins.  Good nutrition is critical.  Dietary habits may be instrumental in about 60% of cancers in women and about 40% in men. (1)

 

Good diets are just as important for dogs. Unfortunately, many of our dogs are eating diets composed exclusively of highly processed, grain-based foods with synthetic vitamins and minerals.  Even the best of the “healthy” dry foods are grain-based. No wonder one in three dogs will die of cancer!  One easy step you can take to help your dog live longer is to add crushed Brazil nuts, a source of natural forms of selenium, to his food. 

 

Selenium is essential to health, and hard to find

Selenium is an essential trace mineral of fundamental importance to human and canine health.  Adequate selenium is necessary for the normal functioning of the immune system and thyroid gland.   Selenium is receiving considerable attention for its possible role as an effective naturally occurring anti-carcinogenic agent.  Recently, the American Association for Cancer Research reported than high selenium consumption may protect humans from bladder cancer. (2)  Animal studies have shown a beneficial effect of high selenium levels in the prevention of cancer. (3)

 

The form of the selenium is important: Natural, food-derived forms of selenium may have beneficial effects not shared by human-synthesized selenium compounds. (4)

 

Dogs evolved consuming two organic forms of selenium: selenomethionine (an essential amino acid found primarily in plants) and selenocysteine (an amino acid found mostly in organ meats).  Most dry and canned dog foods today use an inorganic type of selenium, sodium selenite or sodium selenate. These forms of selenium are considered toxic by the National Toxicology Program of the US Department of Health and Human Services. (5)

 

The body uses the selenium in food differently than food supplemented with sodium selenite.  A 2003 study in The Journal of Nutrition stated that “the absorption, distribution, and excretion of selenium in food were …distinctly different from sodium selenite.” (6)  Natural forms of selenium are superior to human synthesized forms.   Dr. John W Finley, supervisor of the Trace Element Absorption and Bioavailability Laboratory and the Grand Forks Human Nutrition Research Center, and one of the leading researchers on selenium stated:

 

 “Something in the whole foods must boost selenium’s anticancer property,” and  “These results are further evidence that broccoli may be an especially good source of selenium, and nutrition professionals may be wise to take this info into account when giving nutritional advice.” (7) 

 

Is selenium deficiency a contributing factor to canine hip dysplasia?

Insufficient selenium intake can cause serious health problems, including Kashin-Beck disease which is characterized by the degeneration of the articular cartilage between joints (8), thyroid disease and a variety of cancers.  We’ve read unpublished, yet well researched, reports linking selenium deficiency with hip dysplasia. (9)

 

There is a wealth of data about farm animals which shows organic forms of selenium (selenomethionine) outperform sodium selenite.  One of the reasons for this is that natural forms of selenium can be stored in the body for later use, while selenite cannot be stored. (10)

 

Perhaps some dogs are not able to sufficiently use the inorganic forms of selenium found in most dry dog foods.  Therefore, if a bitch were unable to fully utilize sodium selenite, her puppies would be more likely to have joint problems.  Pottenger’s classic study with cats shows that problems due to nutrient deficiency get worse with each generation. (11)   Is the source of the selenium used in most dry dog foods one of the reasons many dogs, purebred and mixed-breed, have hip problems?  It may be one of the nutritional causes.

 

It’s easy to correct this situation

Whether you’re feeding dry, canned, or the best frozen raw diets, you can easily ensure that your dog is getting enough selenium by adding Brazil nuts.  The selenium in broccoli and other vegetables will vary according to the amount of selenium in the soils.  Brazil nuts, on the other hand, are a reliable source of selenium.   Of course, the fresher the nut, the better.  In our home tests with our dogs, freshly shelled Brazil nuts won over shelled nuts bought at natural food markets, in both flavor and fragrance.  We recommend that people add one-half of a crushed Brazil nut per day for every 50 pounds your dog weighs. Since natural forms of selenium are stored in the body, you can easily add one crushed nut every other day, or, for toy dogs, ten pounds or less, one crushed nut per week is great! 

And eat two yourself!
