BEWARE: Mood Swings and Protein Shakes!

How Soy Protein Isolate Affects Your Behavior

Like some of you who are reading this, I too became obsessed with protein shakes. I would have them in the morning while getting ready for the day or I would take them in my car waiting for the weight to drop..so handy, right?  I would believe people when they told me that I was having diarrhea because my “body was cleansing itself”..what?? (I found out later it was the fake sugar). My mood swings were up and down like a yo yo and I observed others taking the same product getting irritable and cranky. At the time I just jotted it all down to them having a bad day. Boy, was I wrong!

After watching Dr. Oz explain how we should avoid soy for our health, I began reading the product label on my protein shake and I noticed the first ingredient listed was “soy protein isolate”.    What was this and what was it doing to my body? This lead me to start my research, partly because I have hypothyroidism and knew I was feeling some negative physical effects.

Soy is Americas largest cash crop being touted as having a myriad of health benefits and it does not matter if it states “non GMO” as this is used as a buzz marketing word. The soy bean is stripped and processed and pulverized right down to expose the garbage waste product called soy protein isolate. Kind of like cardboard.

What’s so bad about soy?:

  • Contains Isoflavones (Genistein and Daidzein).  In soy the isoflavones are built in insecticides.  If they kill bugs are they good for humans?

  • Isoflavones are estrogen like substances which have the same effect as the bodies estrogen.  Cancer comes from having too much estrogen.  Irritability and mood swings, fat gain from the waist down, fibrocystic breast disease uterine fibromas are all associated with estrogen dominance.  Instead of helping prevent the bad effects of environmental or natural estrogen dominance soy isoflavones are now known to increase the bad effect of estradiol and estrone the two major bad guys of the estrogen family.  (1,2,3).

  • Kills testicular tissue.  In men it permanently reduces testicular function and lowers Luteinizing Hormone production. LH is what signals your testicles to work.  This increases the probability of estrogen dominance in men with its hair loss, swollen and cancerous prostates. (4,5).   Male children fed soy formulas and soy products may not ever get to like girls.  Doris Rapp MD, the worlds leading pediatric allergist, asserts that environmental and food estrogens are responsible for the increase in male homosexuality and the worldwide reduction in male fertility. (6)

  • Isoflavones decrease thyroid hormone production. This can stunt children’s growth and make the rest of us tired and fat. (7,8,9).

  • Female children fed the estrogens in soy formula and products hit puberty very very early sometimes as young as age 6 to 8!  (10).

  • Pregnant women eating soy products may affect the sexual differentiation of their children.  Studies show malformations of the reproductive tract or offspring born with both male and female sexual organs. (11).

  • Isoflavones decrease GOOD cholesterol (HDL). (12,13).

  • Soy contains Phytin, which takes essential minerals such as iron, zinc, magnesium etc. out of the body before they can be absorbed.  Also soy contains Trypsin inhibitors block this vital anti cancer enzyme, anti fibrosis enzyme. (14).

  • A 7000 man 30 year epidemiological study done in Hawaii shows soy is connected with a higher rate of Vascular Dementia (Alzheimer’s disease).  (15,16).

Any opinions to contradict the facts noted above have been paid for by the Agribusiness giants Monsanto and Archer Daniels Midland.  Once public knowledge of their manipulation of public opinion and of the FDA becomes widely known, expect monster class action lawsuits against these folks.  They’ll deserve it in spades!

Modified Palm Oil :Good or Bad?

Keeping Ahead of the Food Industry’s Devious Ploys.

So, again I was stuck at the supermarket for 2 “friggin” hours reading labels. Does this sound like you? I noticed that I wasn’t seeing “hydrogenated” anymore…anywhere! Instead, I was seeing a lot of ” modified palm oil or modified palm kernel oil. What was this new word? Was it bad for my family? Just the word “modified” kind of scared me. Changing something into something else that is desired sound like tampering with nature. So, I started inquiring around the store. No one seemed to know what it meant. So, I thought I would investigate and put it out there to inform any one who was interested.

Palm oil is the second-most consumed oil in the world and it is quickly replacing the partially hydrogenated fats (or trans fats) in many of your favorite treats. But there’s a dark side to palm oil. Read on to discover what you need to know about this controversial oil.

Palm oil, derived from the fruit of the oil palm tree (Elaeis spp.), is abundant and inexpensive. It is also odourless, tasteless, and solid at room temperature, which makes it ideal for use in packaged foods, margarines, and shortening.Palm oil is trans fat- and cholesterol-free, making it an ideal replacement for those pesky partially hydrogenated oils.

Good Oil, Bad Fat

In its purest form, palm oil is a source of valuable nutrients, including beta carotene, vitamins E and K, magnesium, and essential fatty acids. However, this form is rarely used, says Patricia Chuey, registered dietitian and manager of nutrition affairs for the Overwaite a Food Group.

Instead, food manufacturers use modified palm oil, which is high in saturated fat and no more nutritious than the partially hydrogenated oils it is replacing, says the Center for Science in the Public Interest (CSPI). In fact, a recent study published in the Journal of Nutrition found a link between the consumption of palm oil and an increased risk of heart attack.

Current recommendations to reduce saturated fat intake have led to listing palm oil among the foods to avoid, says Dr. Jennie Weisenburger, a naturopathic doctor at the Bellevue Natural Health Clinic in West Vancouver. “There are different schools of thought when it comes to saturated fats and the health benefits and the health risks associated with consuming them,” she says. At issue is palmitic acid (the main saturated fat in palm oil); some studies have linked it to high cholesterol and heart disease and some have not, Weisenburger explains.

Palm Oil and the Environment

It’s not just the saturated fat in palm oil that is raising concerns. Palm oil is grown predominantly in Malaysia and Indonesia, where palm oil plantations contribute to the destruction of Southeast Asian rain forests, says a CSPI report released in 2005. Rather than using abandoned agricultural land, which is costly to rehabilitate, palm oil producers clear rain forests and peat swamp forests to create plantations. The soil and water from these lands are polluted by pesticides used on the plantations and the release of effluents into the environment. According to the CSPI report, they are also endangering the lives of the Sumatran tiger, orangutans, elephants, and rhinoceros.

The American Palm Oil Council (APOC) calls the CSPI’s report “highly inaccurate,” accuses them of “excessive exaggeration,” and suggests the study’s authors have never been to Malaysia to study the oil palm industry. Strict laws are in place in Malaysia to ensure the protection of the environment and its wildlife, says the APOC. They point to the Malaysian Palm Oil Industry’s involvement in the Round-table for Sustainable Palm Oil, an initiative focusing on the development and maintenance of responsible, sustainable palm oil plantations, as evidence of their commitment to the environment.

Finding Balance

Though some palm oil producers likely shirk their responsibilities, others take every step necessary to protect the environment and its wildlife. Palm oil and the issues that surround it serve as a good reminder of the importance of being mindful of the impact of our food sources on the earth.

There is no question that palm oil, in its purest form, contains valuable nutrients and can be part of a healthy diet. But, as always, be cautious of consuming too many processed foods. Look for organic expeller-pressed palm oil that is minimally processed. Avoid palm kernel oil, which is less healthy because the oil is extracted from the pit with a hydrocarbon solvent.

Healthy living means not only making choices that are wise for our species but also making choices that keep the Earth and the rest of its inhabitants safe.

Easy Ways to Limit the Palm Oil in Your Diet

  • Get your dietary fats from polyunsaturated fats, especially omega-3 fatty acids (fatty fish, flaxseeds, nuts, nut butters, liquid egg products), and monounsaturated fat (avocados and vegetable oils such as canola, olive, and soybean oils).
  • Limit your consumption of processed foods.
  • Bake homemade cookies and treats instead of buying commercially prepared treats.
  • Daily calories from fat should represent only 20 to 35 percent of total calories (about 45 to 75 g per day for women and about 60 to 105 g per day for men), recommends the Canadian Heart and Stroke Association.
