It’s in Soup, It’s in Cans And It May Be Putting You and Your Family at Risk

In 2012 the FDA banned Bisphenol A (BPA) in baby bottles and sippy cups but  studies continue to mount that show the potential health dangers of BPA.  

Bisphenol A (BPA) is one of the most common man-made compounds. It is a plasticizer used to create water bottles, line metal cans, and coat store receipts. In 2004, the Centers for Disease Control and Prevention conducted a study that found detectable levels of BPA in 93% of the people tested.BPA is so widespread, it has become virtually impossible to avoid it.

The potential effects of BPA are well documented. It is an endocrine disrupter (a class of toxins Kirkman® tests for) that has been studied in both humans and animals and has been linked to alteration of glucose metabolism, early pubescence, declined spermatogenesis and obesity. Studies of animals confirm that even exposure in utero can lead to endocrinal changes that are correlated with obesity later in life.2

In a recent experiment, a family in Austria attempted to entirely eliminate plastic from their lives. The presence of BPAs in their bodies was measured shortly after banishing all offending items from their home. After two months, most of the family members registered only a slight drop in bodily BPA. The researchers attributed the absence of a significant drop to the family’s inability to entirely eliminate exposure to plastics outside of their home. (Additionally there were some methodological problems with the experiment: the family started the experiment with relatively low urinary concentrations of BPA, since they had limited their use of plastics prior to the experiment, and their initial levels weren’t checked until four days after ridding their home of plastics.)3

Though BPA may be impossible to avoid entirely, there is still good reason to at least try to limit your exposure to it. For years, research has unearthed links between this chemical and a wide range of health consequences. Studies of both humans and animals have shown BPA exposure leads to reproductive and cardiovascular problems as well as changes in metabolism.

A recent study indicates bodily concentrations can vary greatly depending on where the exposures originate. One of the most common uses for BPA is in the lining of cans for food, as a plastic lining on the interior that is intended to prevent the foods from developing a metallic flavor. The study found that individuals who consumed one can of food had a 24 percent higher urinary concentration than those who consumed no canned food. Those that consumed two or more cans had a concentration 54 percent higher.

The surprise in the finding, however, was that urinary concentration varied widely depending on the type of food: one or more can of fruits or vegetables led to a 41 percent increase, while one or more cans of pasta led to a 70 percent increase. Canned soups led to a shocking 229 percent increase. Almost as surprising as that staggering number, the study found that drinking canned beverages did not correlate with any increase in urinary BPA concentration.4

The publicity that BPA has received has led many companies to remove BPA from their cans. Though this may sound like good news, in many cases food producers have just switched to other plasticizers that, while not as infamous as BPA, may be just as bad. In their desire to label their cans “BPA Free” they may have switched to PVC, for instance, which is a known carcinogen.

The government stopped short of banning the chemical altogether as other countries have done, however, citing the inconclusive evidence linking the compound to health problems. Recent indications that BPA may be passed to fetuses in utero indicate that children are susceptible to the dangers of BPA before they are even old enough to hold a sippy cup.

Detoxify for a Healthier Pregnancy

  

By Timothy Prentiss
Staff Writer
Kirkman Group, Inc

A few months ago Kirkman® announced the launch of the P2i™ program, an ambitious new project intended to study the roles nutrition, genetics and toxic exposures play prior to and during pregnancy. Initiated by the non-profit organization the Forum, the P2i™ program will track pregnancy outcomes of women who follow the P2i™ protocol, which includes consuming high levels of nutrients and avoiding toxins. The researchers involved in the P2i™ program hope to find that by following this protocol women will be more likely to bear healthy babies who are born free of chronic conditions.

(Click here to learn more about the P2i™ program.)

Kirkman® has created an entire line of supplementsfor the P2i™ program, and is currently the only nutraceutical manufacturer whose supplements meet the exacting standards of the P2i™ program. Central to these standards is an emphasis on avoiding toxic substances. Kirkman’s P2i Baby™ products are Ultra Pure™, meaning they are screened for more than 950 potential contaminants. 

Of course, toxins can come from virtually anywhere (not just from tainted supplements). Environmental toxins can invade our bodies through the air, water, the food we eat and through our skin. Our bodies even produce toxins during certain normal bodily processes.

Whether toxins originate inside or outside our bodies, they need to be converted into compounds that can be safely excreted. This complex detoxification process involves multiple chemical reactions, requiring numerous organic compounds. P2i Baby™ Toxicity Control – Hypoallergenic supports this process by supplying nutrients that are used during the body’s naturally occurring detoxification activities. 

It is offered in vegetarian capsules and includes the following active ingredients:

Vitamin C, Vitamin E and Selenium

Vitamin C, Vitamin E and selenium all enhance the body’s detoxification pathways.

Taurine and N-Acetyl Cysteine

Sulphur-containing amino acids such as taurine and cysteine are required by the liver cells in order for detoxification to occur effectively.

Curcumin

Also known as turmeric, curcumin is a spice that has been shown to induce the body’s production of detoxifying enzymes.

Milk Thistle

Milk thistle is a flowering plant that detoxifies the body’s organs. Silymarin, the active component in milk thistle supports the liver and kidney cells from the toxic effects of certain drugs.

Glutathione

Glutathione is the body’s most powerful immune system supporter. It is also required for the detoxification of methylglyoxal, a toxin produced during metabolism.

Calcium D-Glucarate 

Calcium d-glucarate is required for glucuronidation, a process in which toxins are converted into water-soluble forms that the body can easily excrete.

In the Kitchen with Kirkman®: Cool Down with These Allergen-free Warm Weather Treats

 

 
By Nora Heston Tarte
Contributing Writer
Kirkman Group, Inc.

 

In most corners of the world, families are enjoying hot days in the peak of summer. But those warm weather treats that keep kids cool in the summer heat are often loaded with dairy, sugar, gluten and other allergens. Kids with sensitivities may not be able to run out to the ice cream truck when its song starts playing down the street or order up a scoop (or two) of their favorite flavor at the local ice cream shop.

 With a little work, however, there’s no reason every kid can’t still enjoy these summer staples. Whip up some dairy-, gluten-, sugar-, nut- and casein-free chilled choices for your brood. If you’re trying to keep them busy while school is out, make it a family project and get the kids in the kitchen too! (And if it’s cold where you are, store these recipes away for later use.)

 

Strawberry Ice Cream

Not only is strawberry a refreshing summer flavor, the bright pink color makes it especially appealing to kids! Mix together these alternative ingredients to create an ice cream treat kids with sensitivities can enjoy.

Ingredients –

  • 2 cups, unsweetened, organic frozen strawberries
  • 13 oz. can full-fat coconut milk
  • 1¼ cups unsweetened vanilla hemp milk
  • ½ cup honey
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon lemon juice
  • ½ teaspoon guar gum (optional)
  • 1 teaspoon Kirkman® No Sugar – Sugar Substitute (optional)

Expert Tip: Mix in a serving of Pea Protein Powder to up the nutritional value.

Directions –

Place strawberries and coconut milk in a blender and blend until smooth. Add the remaining ingredients and run again. Place mixture in the freezer for one hour, then remove and pour into an ice cream machine and process according to instructions.

Ice cream can be served immediately. For better presentation, put ice cream into the freezer until it hardens. Allow it to thaw on the counter until slightly softened before serving.

Chocolate Strawberry Banana Smoothie

Ingredients -

Directions –

Put all ingredients into a blender and blend until smooth. Serve immediately and store leftovers in the refrigerator, or freeze them in popsicle molds for a sweet treat for later.

Expert Tip: If your child wants a more liquefied smoothie, add additional water and match ratio to the chocolate powder to avoid diluting flavor.

Gimme Green Popsicles

Use a fruit-based popsicle as a refreshing outdoor treat that forgoes common allergens such as dairy, casein and more.

Ingredients –

  • ½ cup spinach
  • ¼ cup kale leaves, chopped
  • 1 ½ bananas
  • ½ of a pineapple
  • ¾ cup water

Directions -

Prepare the ingredients by cutting the tough stems off of the kale and chopping it into small pieces. Peel and chop the pineapple and banana. Next, puree spinach, kale, bananas and pineapple in a blender. Add water and process again. Pour mixture into molds and freeze until completely hardened – about three hours.

Expert Tip: Buy exciting ice pop molds to add another level of fun!

Frozen Banana Pops

Create a variety of flavors by mixing up the toppings on these banana-based, frozen sweets! The best part is there’s plenty of room to get creative so you can truly customize these pops to meet both your diet and your taste buds!

Ingredients –

  • 4 ripe bananas cut in half
  • Spread of choice
  • Toppings of choice

Directions -

Spread coconut oil, hemp butter, soy yogurt, honey or another item of your choice onto the bananas. Next, roll it over or dip it in the toppings of your choice. Think seeds, sugar-free candy, dried fruit, granola, coconut shavings, raisins or anything else that fits your family’s dietary restrictions.

Expert Tip: All of these recipes make it easy to add a dash of supplements to boost your child’s immune system, or give them a daily dose of medicine they won’t notice. Use flavor-free products when possible and always double-check to make sure the product can be safely mixed and blended. In some cases, applying heat is a supplement no-no, but that isn’t an issue here!

May is Allergy Awareness Month: The Difference Between Allergies and Intolerances

 By Timothy Prentiss
Staff Writer
Kirkman Group, Inc.

 

For decades the rate of allergies has been rising. Media coverage and general awareness of the subject have likewise risen.

Clearly there are benefits to this growing awareness: restaurants are more likely to offer meal options for those with dietary sensitivities, such as gluten; schools are more likely to be more careful or prohibit foods that could cause allergic reactions, such as peanuts and more.

However, the increased attention given to allergies has led to a number of misconceptions. For example, according to an article on the website, WebMD, the number of Americans with food allergies has increased to the point where it’s somewhere between three and four percent; however, the number of people who believe that they have an allergy is nearly 15 percent.1 Put another way, about 10 percent of Americans believe they have an affliction they don’t actually have.

The prevalence of these misconceptions is likely caused, in part, by confusion with intolerances (also know as food sensitivities). Strictly speaking, an allergy causes an immune system response. If this response is sufficiently drastic, it can cause anaphylaxis, a potentially fatal condition during which a person’s blood pressure drops and their airways become blocked.

Unlike allergies, in the case of intolerances, the digestive rather than the immune system has an adverse reaction. For example, a particular food causes irritation in the stomach or intestines; or, the body lacks the enzymes to properly digest food, which can lead to bloating, cramps, diarrhea or other symptoms. Though possibly very uncomfortable, an intolerance reaction (unlike a true allergic reaction) will not be life-threatening.

It’s not just among lay people that there’s confusion about allergies. Even by the standards of medical research, where conclusions and best practices are constantly evolving, the subject of allergies seems particularly murky and full of contradictions. To avoid developing allergies, some medical researchers and physicians, suggest avoiding common allergens, however, others say that we should be exposing ourselves to common allergens, particularly at an early age.2 This illustrates that at the most basic level, there is no consensus about what causes allergies, or, in other words, what allergies are.

The dominant theory holds that allergic reactions are simply a sort of glitch, a dangerous overreaction on the part of the immune system to a non-threat. The immune reaction developed as a defense against parasitic worms (known as “helminths”) that historically were common residents of human intestines. Modern sanitation has left us relatively worm-free, consequently, IgE antibodies that in the past kept these worms in check will mount attacks against harmless proteins that bear similarities to helminth proteins. This explanation for the cause of allergies has led to “worm therapy,” in which parasitic worms are intentionally introduced to the bodies of allergy sufferers. This method has shown some promise.

Recently, a researcher at the Yale School of Medicine has been testing an alternate hypothesis. Ruslan Medzhitov believes allergic reactions are not simply dangerous overreactions to harmless substances. Rather, he believes allergens themselves can cause cellular damage; the allergic response (though dangerous) actually performs a protective role.3 

Clarifying the cause or, if Medzhitov is correct, the purpose of allergic reactions will no doubt lead to refinements in treatment methods. More importantly, there may eventually be an explanation for the continuously increasing number of allergy sufferers.

In the Kitchen with Kirkman®: Making Summer Camp Snacks Nut Free!

 
By Nora Heston Tarte
Contributing Writer
Kirkman Group, Inc.

 

Many schools have made the move to “nut-free zones” in order to accommodate children with life threatening allergies. While the decision has been met with mixed reactions, the goal is to keep children with food allergies safe at school, while allowing parents peace of mind during the time their children are away. The policy also spills over into many camps and after school/summer activities.

Whether your child suffers from allergies or not, chances are you’ll need to learn how to pack some tasty treats for their lunch boxes without the use of peanuts or tree nuts. Take it a step further with these recipes for snacks and lunches for kids—free of dairy, gluten, fish, refined sugar, eggs and nuts!

Pea Butter and Jelly Sandwich

Does your child love peanut butter and jelly sandwiches, or have they never been able to try the American staple due to food allergies?

 A safe and healthy alternative to the often forbidden lunchtime snack is pea butter.

 Yes, that’s right: Pea butter!

 Yields 1 cup

Ingredients:

  • ⅔ cup dry whole yellow peas
  • ½ cup water
  • 2 ½ tbsp refined coconut oil
  • ½ tablespoon agave nectar
  • ¼ teaspoon sea salt
  • Gluten-free bread, sliced
  • Jelly of choice, sugar-free

 Directions:

  • Soften peas by placing them in a bowl and cover with one inch of cool water. Cover and let stand 24 hours.
  • When ready, preheat the oven to 350° F and line a baking sheet with parchment. 
  • Drain peas and spread in one layer on the sheet. Bake for one hour, stopping every 15 minutes to shake the pan (prevents burning).
  • Place the peas in a bowl to cool. Once cooled, move them to a food processor and add water.
  • Let stand 15 minutes then pulse until finely chopped. Add oil, agave and salt and run the food processor until the ingredients turn into a smooth, thick paste, adding more water if necessary.
  • Spread desired amount on gluten-free bread of choice, add sugar-free jelly. Voila!

 Can be stored in the fridge for up to two weeks.

Insider Tip:

Use the same pea butter as a spread for vegetables, gluten-free crackers and more!

 Busy Mom Hack:

Buy pea butter by the jar. It’s harder to come by than traditional peanut butter, but health-conscious brands make the blend with safety in mind.

 Chicken Noodle Salad

Kid lunches don’t have to be bland. In fact, there are plenty of ways to stuff your child’s lunchbox with flavorful foods that are allergen-free! Make this chicken and noodle salad packed with protein and plenty of veggies.

Yields 4 servings

Ingredients:

  • 4 ounces cooked, gluten-free, whole wheat pasta of choice, rinsed in cold water
  • 1 cooked chicken breast, diced
  • 1 large carrot, peeled and sliced
  • 1 red bell pepper, seeds and core removed
  • ½ cup sugar snap peas, sliced
  • ¼ cup dressing of choice, or fresh lemon/lime juice

Directions:

Cut all vegetables into matchstick slices. Combine with chicken and pasta. Serve with dressing or fresh squeezed juice of your choice.

Insider tip:

Meet picky eaters halfway. Do they have a favorite vegetable? Perhaps green bell peppers are favored, or olives sound more appealing. Mix in your child’s choices to customize this dish to their liking.

Busy Mom Hack:

Reuse the recipe but switch it up with different dressings, or serve over gluten-free rice instead of pasta!

Carrot Salad

Kids love color and crunch in their lunches, and as an added perk, this carrot salad tastes best when made ahead of time. Serve it with vegetables, fruit or gluten-free crackers for dipping.

Yields 6 servings

Ingredients:

  • 3 large carrots, grated
  • ¼ cup finely chopped fresh parsley
  • 3 tablespoons raisins, sun-dried cranberries or both
  • 3 tablespoons red-wine vinegar
  • 5 tablespoons olive oil
  • Salt and ground black pepper to taste

Directions:

Combine all dry ingredients in bowl. Toss and add oil and vinegar. Store in refrigerator until ready to serve.

Insider Tip:

Spread a tablespoon of dairy-free cream cheese on gluten-free bread and add the salad in between for a satisfying—albeit unusual—sandwich.

Busy Mom Hack:

Make it in the morning and send it to school with your brood (using proper refrigerating technology of course). By the time lunch comes around, the timing will be perfect.

Quinoa Pizza Bites

What kid doesn’t love pizza? Now you can serve it without feeling guilty about your child’s healthy diet being compromised, and free of worry they’ll be exposed (or expose a classmate to) potential allergens.

Yields 12 bites

Ingredients:

  • ¾ cup quinoa, uncooked
  • ¼ cup water
  • 2 tablespoons olive oil
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup marinara sauce
  • ½ cup dairy-free mozzarella and/or Parmesan cheese, shredded
  • 12 slices pepperoni
  • Ground pepper to taste
  • Oregano to taste

Directions:

  • Soften quinoa by soaking in water for about six hours. When ready to cook, preheat oven to 425° F.
  • Place small strips of parchment paper into each section of a muffin pan, and coat each with olive oil.
  • Place quinoa, water, remaining olive oil, baking powder and salt in blender. Run on high until it becomes a thick batter
  • Pour batter in muffin pan.
  • Bake for ten minutes, take out, flip onto a baking sheet, and bake for another 10 minutes or until edges are crispy and browned. Remove. 
  • Top with marinara sauce, shredded, dairy-free cheeses and pepperoni.
  • Return to oven for 8 minutes. Pull out and sprinkle with pepper and oregano.

Insider tip:

Place bites into a thermal lunchbox immediately so they stay warm for lunch or snack time at school!

Busy Mom Hack:

Can’t complete this task in the morning? Save it for free time while the kids are at school and hand deliver the warm bites at lunch. Check ahead to make sure this doesn’t violate your school’s policy.

Add a treat

 

 

Before you send your kid on their way, drop in a Just Fruit Pear Bar. This pure-fruit bar is packed with nutritious ingredients, free of casein, gluten and other major allergens and is certified vegan.

Fathers-To-Be, Your Good Health Matters Too!

 
 By Timothy Prentiss
Staff Writer
Kirkman Group, Inc

 

Women receive all kinds of prenatal healthcare services and advice. Far less attention is usually given to the health and nutrition of fathers-to-be, however, research is making it clear that the prospective father’s health is also important. The environmental exposures and nutritional choices of a father-to-be can have profound effects on reproductive outcomes, from failure to conceive to birth defects.1

The Effects of Environmental Exposures

Smoking and excessive drinking are likely the most common (and most commonly recognized) reproductive hazards and both can lead to reduced sperm counts.2  But there are other common exposures, including many encountered in workplaces, that can have detrimental effects on fertility.1

Millions of chemicals are commonly in commercial use. According to the CDC, more than 1,000 of these have reproductive effects on animals, but few have been studied in humans. Several of those that have been studied have been shown to lower sperm count, deform sperm shape (which can lead to an inability of the sperm to “swim” effectively) and/or alter sexual hormones.

Lead, for instance has been linked to all three of these negative outcomes. Exposure to other heavy metals as well as pesticides have also been linked to negative effects on sperm production. Potentially damaging chemicals used in workplaces include bromides (used in dyes, disinfectants and insecticides), styrene (used in plastic production) and tetrachloroethylene (used in dry cleaning).1

Some chemicals can actually alter the DNA contained in sperm cells, potentially leading to miscarriage or health problems for the offspring. Certain cancer medicationshave been found to have such an effect, as has smoking,3 however there isn’t yet much data on whether or not any chemicals used in workplaces can alter DNA.1

The Critical Role of Nutrition

High body mass has been linked to low sperm counts, both oligozoospermia, which simply means a lower-than-average count, and azoospermia, which indicates a sperm count so low that sperm is actually undetectable.

For both underweight and overweight men, there is a slightly increased chance of azoospermia or oligozoospermia. Those deemed “morbidly obese,” however, have twice the odds of low sperm counts.4

Research on the impact of diet on male fertility is still at an early stage, but it has already become clear that poor diets have a negative effect. A 2012 study found that men who ate diets containing large quantities of fruits and vegetable had sperm with greater motility than those who ate a standard western diet including greater amounts of fat and refined grains.5

Though this study only indicated that having a generally nutritious diet was beneficial, other studies have narrowed their focus to look at specific nutrients. One found that vitamin E and selenium supplementation both increased motility and reduced the concentration of malformed sperm.6 Another found significant count and motility improvements following regular, high-dose intake of vitamin C7. High doses of vitamin B-12 were found to increase sperm counts for both humans8 and rats.9

P2i BabyTM

Kirkman’s new product P2i Baby™ Preconception Vitamins & Minerals for Men – Hypoallergenic — part of Kirkman’s P2i Baby™ line—is packed with these nutrients that have been shown to improve male fertility. It includes 142% of the recommended daily allowance of selenium and 100% of the recommended daily allowance of vitamin E, which have both been shown to improve motility and sperm count. High levels of vitamin C and vitamin B-12 are also included (416% and 1,666% of recommended daily allowance, respectively).

These supplements are Ultra Pure™, meaning they are tested for and verified free of more than 950 environmental contaminants. Not only do they provide nutrients that have been demonstrated to improve fertility for men, they are also free of chemicals that have been shown to negatively affect fertility.
