For many years, there has been a medical controversy whether to eat and to feed your pet foods that contain plant based estrogens (phytoestrogens).
The controversy involves whether phytoestrogens bind the estrogen sites in the body, thus stopping harmful estrogen from other sources from binding these sites; or do the phytoestrogens actually cause a health risk adding to the amount of estrogen occurring in the body, as do xenoestrogens and other estrogen mimickers?
Recent information published by researchers from the University of Toronto measures and lists the actual amounts of phytoestrogens that occurs in many foods we eat and feed our pets.
Past lists of food containing phytoestrogens were rarely measured and if they were, they never included the amounts of nine different groupings of phytoestrogens. The sub groups of phytoestrogens that were measured are as follows:
I have included in my article Natural Estrogens That Occur in Nutrients, a list of foods published by the University of Minnesota and other websites, and in addition, my own clinical experience.
The following list of foods, for the first time, measures all nine sub-groupings that contain phytoestrogens and measures the actual amount of phytoestrogen each food contains.
Foods Containing Phytoestrogens:
Based on 100 grams of each specific food:
Alfalfa (sprouts) 441
Meats from mammals (ham 2.3, hotdog 3.1, breakfast sausage 1.2) Note: Please realize that meats and dairy products may be low in phytoestrogens, but contain huge amounts of total mammalian estrogen and should not be consumed in the case of estrogen dominance.
Dates (Dried) 329
Licorice (Black) 862
Oats (Oat Bran Bread is 13.2)
Red beans 10.4
Sesame Seeds 8,008
Soybean Sprouts - 789
Sunflower Seeds 216
Estrogen Inhibitors - Foods Low in Phytoestrogens and High in Aromatase Inhibitor:
Berries (Blueberries 17.5, Raspberries 47.6, Strawberries 51.6)
Citrus Fruits (Oranges 19, Grapefruit 6.2)
Most Fruits (Peaches 64.5, Banana 2.6, Cantaloupe 7.1)
Green beans – 105.8
Melons (Watermelon) 2.9
Squashes (Zucchini 5.1, Winter Squash 113.7)
White Rice 6.2
White Flour (White Bread is 5.7)
Please remember that the foods listed below that contain meat and dairy products will have a higher estrogen content than listed.
Veggie Burger 1,671
Peanut Butter 80
Olive Oil 180
Multi Grain Bread 4,798
Protein Bar 2,723
Tuna (Canned) 1.3
Milk (Cow) 1.2
Coffee (Regular) 6.3
Tea (Black) 8.9
Orange Juice 8.6
Red Wine 53.9
White Wine 12.7
Hopefully this will give you an idea about foods that contain phytoestrogens to eat or not to eat.
Estrogen deficient humans or animals will actually know the food they need to eat.
Those humans and animals that are estrogen dominate will know the foods to stay away from.
Please also make sure none of these plant foods come from GMO seeds. For more information please go to www.drplechner.com and under Foods and Supplements, please read the article titled, Effects of GMO’s for You and Your Pet.
Hopefully the information in this article will help keep you and your pet healthier, happier, and live a longer life.
