Should I Stop My Statins?

(0) Comments | Posted January 7, 2014 | 5:00 PM

You've probably heard of Lipitor, Zocor, and Crestor. You may even be taking one of these cholesterol-lowering drugs, which are known as statins. They are the most commonly prescribed medication, and for years, they’ve been touted as the best way to manage cholesterol.

Now, top Harvard cardiologists are questioning current cholesterol guidelines. The data to support this claim isn’t as solid as we thought, and we are now seeing that statins can cause some serious side effects, such as:

  • Muscle pain, damage, and aching
  • Mitochondrial damage
  • Type 2 diabetes
  • Neurologic problems such as memory loss
  • Sexual dysfunction

In fact, researchers are now learning that mistakes were made in previous studies, prompting doctors to prescribe statins to patients who really didn’t need them. And this is a dangerous mistake to make, because statins come with some serious risks. More cardiologists are speaking out.

We used to think that there were very few side effects associated with this drug, but the truth is, up to 20 percent of statin users have experienced serious side effects like muscle pain, damage, and aching or high muscle enzymes. Statins can also poison your mitochondria, which are your cells’ energy-production factories and the single most important factor in healthy aging and wellness. Statins can hinder the mitochondria’s ability to produce energy effectively and can even kill cells off completely.

In one study, two groups of overweight, sedentary people were put on an exercise program for 12 weeks. One group was given a statin and the other group wasn’t. After 12 weeks, the group that had been taking the statin saw no improvement in their fitness level. It was as if they hadn't exercised at all! In fact, when muscle biopsies were performed, doctors found the members of this group had four and a half percent less energy-production capacity in their cells. They were actually in worse condition than before they started the exercise program!

This is quite serious. I believe, in the next 10 years, we're going to see a backlash against statins. In fact, we're starting to see it already. We’re seeing now that they may not benefit everybody we thought they would. And we’re seeing that there are some serious risks involved. So, stay tuned for more on this.

In the meantime, I encourage you to read my blogs on statins, which show how they cause diabetes and neurologic problems. Also, read my blogs that explain how you can optimize your cholesterol and get the right type of cholesterol. Learn more about how to take care of your heart in a way that supports your health rather than damages it.

5 Steps to Solve Your Migraines

(1) Comments | Posted January 2, 2014 | 8:59 AM

Migraines are a big problem. They affect millions of people and are responsible for billions of dollars in health care costs. In fact, they're one of the most common reasons people end up the emergency room.

The question we really need to ask isn't, "How do you treat a migraine?" but rather, "What is causing the migraines?"

This is where Functional Medicine comes in. Functional Medicine is medicine by cause, not by symptom. It helps us discover the underlying triggers of disease. And you know what? The root cause of your migraine may not be in your head at all. In fact, it may be caused by many other factors. Let's go through some of the things that can cause migraines, because 10 people with the exact same symptoms might have very different underlying causes.

Migraines can be caused by:


  1. Sensitivity to foods like peanuts or dairy or eggs. I had a patient who had migraines for 40 years, and we discovered that they were caused by the eggs she was eating. When she stopped eating eggs, the migraines went away; when she started eating them again, the migraines came back.

  2. Gluten allergy. This is a special kind of food allergy that creates a lot of inflammation. Many people are sensitive to gluten, the protein found in wheat, barley, rye, oats and spelt.

  3. Hormonal imbalances. For example, many women get premenstrual migraines, which is often caused by imbalances in estrogen and progesterone -- too much estrogen, not enough progesterone. This can be caused by stress; by consuming too much alcohol, sugar, flour and starches; and by not getting enough exercise or sleep.

  4. Vitamin B deficiency. Some people who don't get enough riboflavin get migraines.

  5. Imbalances in melatonin. Newer studies have shown that this may be related to sleep cycles, which can be improved with melatonin.

  6. Magnesium deficiency. Magnesium is the relaxation mineral. If you're deficient in it, you can often get headaches and migraines. I once had a patient with chronic migraines who tried everything to cure them, but nothing helped. It turned out that she had a massive magnesium deficiency. I gave her a very high dose of magnesium, and her migraines went away.

So, remember: migraines are not all the same. You have to find the underlying cause. Here are some simple things you can do to identify and eliminate what might be causing your migraines:

  1. Do an elimination diet. Get rid of the common food allergens. Use my book The UltraSimple Diet as a guide.
  2. Try magnesium. Take 300 to 600 milligrams twice a day in the form of magnesium glycinate or citrate.
  3. Try riboflavin or vitamin B2, 400 milligrams a day. It will turn your urine a dark yellow, but don't worry about it.
  4. Balance your hormones to stop premenstrual migraines by exercising; eliminating caffeine, alcohol, and sugar; and eating a diet rich in plant foods, especially the broccoli family, flax seeds and tofu as well as other vegetables, and fruits.
  5. Try melatonin, which has been shown to help relieve migraines. Take 1 or 2 milligrams at night.

These are just a few simple things you can do at home to fix your migraines, and I have many more suggestions. So, I encourage you to read my blogs on migraines and take advantage of the information on my website.

And if you like this House Call, I encourage you to share it with your friends and family on Twitter and Facebook, sign up for the newsletter, and submit your questions, so that, next week, I may make a House Call to you.

Wishing you health and happiness,

Never Eat These FrankenFats

(39) Comments | Posted December 9, 2013 | 10:29 AM

Thank God! Trans fats are banned at last. But they are still in our foods, so beware!

Recently, the FDA issued a ban on all trans fats, deeming them unsafe for human consumption, and it's about time! For more than 20 years, the science has shown these fake FrankenFats to be hazardous to our health. Thankfully, the government has finally caught on.

Trans fat was invented for use in margarine and shortening. But do you know why they call it shortening? Because it shortens your life! It was supposed to be a better butter, but in fact, it's worse. Did you know that if you put butter and margarine side by side, flies will land on the butter but they won't land on the margarine? It's just too toxic for them. The trans fat it's made from is an oddly shaped fat that:

  • Slows your metabolism
  • Causes weight gain
  • Increases inflammation
  • Lowers your good cholesterol
  • Raises your bad cholesterol
  • Causes diabetes, obesity, heart attacks, strokes, dementia, cancer, and inflammation


The first step in getting trans fats out of our food supply was the change in food labeling laws. Food manufacturers actually had to put the amount of trans fat in their junk food on the label. But there was a loophole created by food industry lobbyists that allowed them to hide the trans fats. They ONLY had to notify consumers that their product contained trans fat if it was greater than half a gram per serving. If something says zero trans fat, it can still have lots of trans fats.

Take, for example, whipped topping like Cool Whip. The label says zero trans fat, but if you look closer, you'll see it says water and partially hydrogenated fat and high fructose corn syrup. Well, partially hydrogenated fat is trans fat. But because the law states that you can say zero trans fat on the label if there is less than half a gram per serving, they can put zero trans fats. Since most people don't know that hydrogenated fat and trans fat are the same thing, food makers have been able to hide the trans fat content in plain sight using this little trick.

Finally, the FDA has officially declared trans fats to be unsafe and has banned their use. And you know that when the FDA stands up to the powerful the food industry lobby, it's got to be bad.

So, you really don't want to eat anything made with trans or hydrogenated fats. The purpose of trans fat is to prolong the shelf life of the food. It never goes rancid. You can make piecrust out of shortening even if it has been sitting in the cupboard for 30 years. You know why they call it shortening? It shortens your life. Flies won't even land on it if you leave it out on the counter!

It is hidden in almost all convenience food and fried foods:

  • microwave popcorn
  • cupcakes
  • cookies
  • donuts
  • many fried foods
  • pizza
  • baked foods
  • frozen foods


And don't just look at the trans fat content of the food; look on the label for the word hydrogenated, and make sure it doesn't have that on it. This one simple thing will improve your diet and upgrade the quality of the food you eat. You'll feel better and you'll be healthier for it.

So, now I'd like to hear from you. Leave a comment below and let me know what you think about the FDA's trans fat ban. Have you eliminated foods made with trans or hydrogenated fats? Has this improved your health? Let me know. And if you'd like to receive this newsletter each week, sign up on my website. Share it with your friends and family on Twitter and Facebook and send me your questions, so that, next week, I may make a House Call to you.
