It's extremely unfortunate and really maddening that Trump signed an order to protect the maker of Roundup, Bayer aka Monsanto last week as a matter of "national security."

For those who haven't been following my posts about this, glyphosate which is the main ingredient in the formulations for herbicide in most of America's non-organic farming, has been strongly linked to cancer in human studies and causative in animal studies in multiple studies.

The hilariously ironic part is those who supported RFK, Jr. because he was trying to make America healthy again aka MAHA, now realize that he doesn't really have our interests at heart. (He signed off on this order as necessary.)

It's not even just cancer.

Take a look at the screen capture I have attached: it's from a study showing that 99% of women having children in Indiana contain levels of glyphosate in their blood in urine. And those who have more glyphosate in their samples have lower birth weight babies.

Your food supply is not healthy If you're eating non-organic vegetables.

You got to take a look at the Environmental Working Group site. They're testing everything year to year. You can eat non-organic for what is safe.

My parents have said, "Well, we've eaten whatever we wanted, nothing's happened to us." (Which by the way isn't even true.) But if you're over 80, half your food supply was probably okay. If you're under 80 it's not.

It's extremely unfair because a lot of people can't afford to eat organic and a lot of grocery stores don't even carry a good selection of organic foods at reasonable prices. The best I could say is check the EWG website for what is okay to eat non-organic.

In the end, food supply is only part of the equation in being healthy, but it's a big part. You still can protect yourself with adequate exercise, low stress, removing emulsifiers, and everything else you see me posting about.

I just don't like it when the government isn't looking out for our best interests.

A very important announcement was made in the news today. A very powerful herbicide that is a mixture of agent orange and glyphosate is being taken off the market. Likely not due to a health ban, but probably some economic reason. It's a mixture of agent orange and glyphosate. Both of them have been linked to many diseases but especially relevant for my work is that they both have been linked to increase cancer rates.

They've been sprayed on non-organic soy, corn and cotton for decades.

In this study of 68,000 people, they found that people who had the highest organic food consumption had a 25% lower risk of getting cancer over the study period.

This is why I recommend everybody to eat organic foods and use organic cotton as much as possible budget depending.

A very important announcement was made in the news today. That will be bypassed because of all the political stuff you're probably reading. A very powerful herbicide that is a mixture of agent orange and glyphosate is being taken off the market. Likely not due to a health ban, but probably some economic reason. It's a mixture of agent, orange and glyphosate. Both of them have been linked to many diseases but especially interesting and relevant to me is that they both have been linked to increase cancer rates.

They've been sprayed on non-organic soy and corn and cotton for decades.

Why did the EPA allow these to be used at all?
Wasn't all the veterans getting dozens of diseases including many cancers enough? Nope.

That's a important question and why I recommend everybody to eat organic foods and use organic cotton as much as possible budget depending.

Very excited to have my book Healing Before You're Cured on the bookshelf at my favorite vegan restaurant, Follow Your Heart. If you've never been there, it's an iconic spot for vegetarian and vegan food on Sherman Way in the valley. You need to go. You've probably seen the labels in grocery stores all over the United States, mostly on their salad dressings in the refrigerated section!

And if you're there go check out my book, there are signed copies on the bookshelf.

Shout out to my "book publicist," who talked to the manager, the amazing Rosanna, the first time to get it considered on the shelf!

Happy New Year!

At dinner the other night Hal Zeitlin asked me what would be different if I wrote Healing Before You're Cured now (if you didn't know I wrote a book on integrative medicine a few years back). What has changed, he asked?

The premise of the book, that physical mental emotional and spiritual health all ties together to give you the best health, that is the same.

What has changed is the science. One of the biggest questions I used to get in talks was "does it matter to eat organic?"

Intuitively I would say yeah it does help but at that time, and at this time, organic vegetables are still more expensive, significantly so. The data supporting this intuition was fairly non-existent.

Since that time, there has been a few large scale studies looking at people who eat organic food versus non-organic. And the difference in cancer rates between the two is about 25%. Meaning that people who eat only organic have about a 25% lower rate of cancer.

The biggest study of course didn't happen in the United States. It was in France (screen caps below) and if you want the reference let me know.

Now the question is why, why doesn't the United States care about this very important topic? We spend trillions of dollars on medicine in this country, why not look at the food? (That's an entire topic on itself!)

The biggest reason that organic food matters is the type of pesticides that are used. In December one of the largest studies supporting the use of Roundup was retracted by the journal that published it in 2000. I noted that because I follow the science very closely.

Today, the New York times finally published an article about it- that the supposedly seminal paper was tainted, that the researchers were actually heavily influenced by Monsanto, and their internal scientists directing the study from behind the scenes.

Regardless, if you have the financial means and you care about your health, I would eat only organic vegetables and fruits. It's not because non-organic vegetables and fruit are inferior, it's that the pesticides used are completely different in terms of their carcinogenicity.

Happy New Year!

Very honored to have been on Jenn Greenhut's Instagram Live show "What's Your Story" segment. Jenn has an incredible nonprofit called Love Zero Negative, focusing on triple negative breast cancer survival.

Big takeaways are:
1.the power of boosting your vegetable servings trying to get to a goal of 30 servings a week. This has incredible benefits.

2. Meditation is easy. Just start doing a little bit at a time. Here's the YouTube link for the IG live video we did.

Pay attention to the temperature of your cooking. Over 275° bad stuff starts to happen: You'll start producing carcinogens. Acrylamide, HCAs, PAHs start forming with increasing concentration with increasing temperature.

Keep your dial on your stove at low/medium to avoid forming these molecules!

Lion's mane is a great mushroom to protect your cognitive faculties. Proven in studies to do just that.

Been in and out of the hospital seeing older friends after a fall the last couple months. I want to remind anybody over 65 that after a hip fracture, the chance you dying in the next year is 28%.

How do you counter the risk of falling? You have to make sure your muscles are strong enough to catch yourself when you trip.

I asked older patients all the time How do you prevent yourself from falling? They usually say "I'll try not to trip" or "I've got to be careful at night when I go to the bathroom."

Those things are helpful but the reality is we all trip. We all stumble. It's just that when you're younger you can catch yourself because you have the muscle strength.

Here's a study and people over 60 showing that weightlifting even just for a year gives you benefits for the next 5 years. This is how you stop yourself from falling: By having the strength to catch yourself when you inevitably trip.

Your personality style predicts for cancer risk! Type A, type B, and then there's the type C. That's a suppressive type that you probably didn't know about. If you don't react at all, and you're generally stoic for every single event you might be that type C!
