The most dangerous food for your heart… Isn’t sugar. It’s something far more common... and it’s probably in your pantry right now. Here’s what it is and why it’s worse than you’ve been told: 🧵

Sugar is harmful to your heart. But there is a food that does even more damage. Some believe it must be omega-6 oils like soy or corn oil. These are harmful. Yet there is a form of these oils that is far more destructive. They are called trans fats.

You may think trans fats were banned years ago. But they never completely disappeared from our food supply. In fact, food manufacturers still use them in ways that are hard to detect. And the health risks are severe.

Trans fats can: • Increase the risk of heart attack and stroke • Worsen insulin resistance and type 2 diabetes • Promote cancer Emerging research also suggests potential links to autoimmune conditions, infertility, and even bone health. Why are they so harmful?

Trans fats are harmful because of how they are made. Oils like soy, corn, or canola are heated to extremely high temperatures and chemically altered. This process changes the structure of the fat and creates partially hydrogenated oils, the main source of trans fats.

When you consume these fats, they become part of your cell walls and blood vessels. This makes your arteries stiff, inflamed, and more prone to damage. It also raises the risk of serious heart problems. To make matters worse, food labels can be misleading…

If a product contains less than 0.5 grams of trans fat per serving, it can legally claim “zero trans fats.” Most people eat more than one serving, so the amount can add up quickly. Independent testing shows many foods labeled “zero trans fats” still contain significant amounts.

Even when companies reduce trans fats, they often replace them with fully hydrogenated oils. These might not be labeled as trans fats, but they are still highly processed and can harm your body. You might be surprised how many everyday foods still contain them.

Trans fats are also found in: • Pie crusts • Popcorn • Cookies and crackers • Croutons • Certain beef sticks and snack foods • Many restaurant meals Even hospital and school meals often contain them.

Here is how to protect your heart: • Read labels carefully • Avoid anything with “partially hydrogenated” or “hydrogenated” oils. • Choose natural fats from grass-fed animals or healthy oils like olive, avocado, and coconut. Your heart depends on it.

Every 2% increase of trans fats in your diet raises your risk of dying from a heart attack by up to 35%. That is why avoiding them completely is essential. The challenge is that trans fats hide in many everyday foods, even ones you think are safe.

@dr_ericberg Everyone knows until they know better. The simple answer is to buy fresh produce and cook from scratch, steer clear of mass produced crap. That way when every bright spark changes their minds as to what’s the worst thing you can consume you won’t need to worry.

@dr_ericberg Stop the sugar fear-mongering! The “sugar is harmful for your heart” line was built on bad science that lumped sugar with PUFA + trans fats. In reality, sugar fuels thyroid + glycogen, lowers stress hormones, and protects the heart. PUFA is the real culprit.

@dr_ericberg Root cause. Doctors today never look for root cause. They don't use the words"'cure" or "heal" which ps is the job of a physician. They "treat" with petroleum based drugs. They treat lab tests not people. They try to kill the problem and manage the sickness (telling people they

@dr_ericberg Does this fat transform you in a transsexual?

@dr_ericberg Your thread is gaining traction! #TopUnroll https://threadreaderapp.com/th... 🙏🏼@GoldStuart for 🥇unroll

@dr_ericberg Great info Dr. Berg. Thank you. 🙏 (shared)

@dr_ericberg I just heard that heating olive oil can turn it into trans fat. Is that true? If so what is the best oil to cook with?

@dr_ericberg How are drugs "petroleum based?"

@dr_ericberg I’m sorry am I the only one that thought this might be an article on why men shouldn’t wear Speedos? 🤣

@dr_ericberg Read labels if it has a word that sounds like “genated” on the end avoid

@dr_ericberg Us you are doing a holy job to aware about these facts . May god bless you with healthy and happy life .

@dr_ericberg Could you discuss the thought that the heart is a vortex, not a pump? Dr. Tom Cowan and others has some different, thoughtful, as in thinking differently, thoughts on what we have been told.

@dr_ericberg everything that nature didn't create is dangerous to our hearts or health...

@dr_ericberg Vagina?

@dr_ericberg I learned about hydrogenated fats and seed oils a long time ago and rarely if ever eat any and avoid eating out for the reason that most restaurants use both.

@dr_ericberg Thank you! I have completely fixed this for the last two years being in a carnivore diet with grass fed butter and the occasional avocado.

@dr_ericberg Great thread One often overlooked fact is that trans fats don’t just harm your heart, they also impair your immune system by promoting chronic inflammation, which can affect everything from recovery to overall resilience against illness.

@dr_ericberg The most dangerous food, Pfizer

@dr_ericberg You are a blessing. When I tell people that trans fats etc. are unhealthy, they typically shrug & say, "I've always eaten it". I've found that people are often unwilling to change their
