Nutrisystem side effects: Cancer warning | Side Effects


1. Nutrisystem Cancer Warning?!

I was shocked to see that people Google Nutrisystem cancer warning so I decided to look into it. After some research, I was able to find a statement from Nutrisystem on Facebook in regard to the cancer warning:

“In accordance with Prop 65 we need to disclose a warning that consuming our foods or dietary supplements can expose. you to chemicals including lead, which is known to the state of California to cause birth defects or other reproductive harm.

The chemicale that the state of California requires us to warn customers about are naturally present in the soil, like lead, that plants take up while growing. Other chemicals, lie acrylamide, naturally form when foods are browned.”

Essentially, Nutrisystem is complying with Prop 65 a controversial California law requiring companies to disclose if there may the presence of one or more of the 900 or so substances on the Prop 65 list. Companies like Nutrisystem list the cancer warning to avoid lawsuits, but the wording usually shocks customers.

Prop 65 warnings are everywhere!

This cancer warning became California law 30+ years ago with good intentions, but many people think Prop 65 is too far-reaching and alarmist and needs to be reigned in.

Anyway, Nutrisystem food is packaged and not organic, so if that bothers you, maybe consider an organic diet or meal delivery like Factor 75.

2. Does Nutrisystem Cause Cancer?

There is no evidence that Nutrisystem causes cancer. In fact, clinical data show that obesity is clearly linked to an overall increased risk of cancer. So, dropping that extra weight should actually reduce your risk of many kinds of cancer.

Also, Nutrisystem asks you to supplement their foods with groceries including fresh vegetables and fruits which have been shown to reduce your risk of certain types of cancer.

Want to lower your cancer risk? When choosing groceries to supplement your Nutrisystem meals, check the labels for toxic ingredients like high fructose corn syrup, artificial sweeteners, refined grains, and sodium nitrates which may be linked to cancer risks.


3. Most Common Nutrisystem Side Effect? Gas!

Fiber is really good for you! Eating foods high in fiber makes you feel less hungry, which is great for weight loss.

The American Heart Association states that having a diet high in fiber (25+ grams per day) can also improve your cholesterol levels while lowering your risk of heart disease, obesity, and stroke.

Nutrisystem understands fiber’s benefits, and that’s why its food is relatively high in it. So, what could be bad about that?

Fiber can cause gas! That’s probably why some users complain in their reviews of feeling bloated and gassy on Nutrisystem.

You see, when you start Nutrisystem, you make the switch to foods that are generally low in calories and high in fiber. Your body may need time to adjust to this healthy change in your diet; specifically to the increase in fiber.

Tip: While increasing your fiber intake may result in positive side effects like weight loss, it may cause gas. (aka burping and farting) For help identifying your specific type of flatulence, click here

While gas is the most common side effect of Nutrisystem’s fiber-rich foods and probiotic shakes, other side effects include abdominal pain, stomach problems, bloating, constipation, and diarrhea.


4. Side Effects from Preservatives?

So, why do several customers report that eating Nutrisystem food made them sick?

The majority of food that you eat while on Nutrisystem is packaged meals and snacks. Packaged foods of all kinds use preservatives to keep the food fresh. These preservatives are common in prepared foods, and while they are FDA regulated, their presence, along with higher fiber content, may cause side effects in certain people.

Since many of Nutrisystem’s prepared foods include preservatives like nitrates, you may experience side effects from them including headache, lightheadedness, and nausea.

Tip: Consider reading user reviews of the Nutrisystem program as well as for specific Nutrisystem foods (on their site) to learn of potential side effects

5. Side Effects from Nutrisystem Food Ingredients?

Because Nutrisystem sends you prepared foods, you should be mindful of their ingredients, especially if you have allergies or sensitivities to certain foods.

Nutrisystem has special plans for both men and diabetics, and all plans require you to supplement your foods with fresh groceries like fruits and vegetables, which may cause similar side effects.


6. Any Sudden Change In Diet Can Cause Side Effects!

When you change your diet, your body needs to adjust. If you are used to eating a lot of empty carbs, then the change to a healthier diet that is high in fiber and protein can cause side effects like gas.

Talk to your doctor before starting any diet, and report any potentially serious side effects or discomfort right away.
