Here’s the ugly truth about avocados (that you won’t like):

I used to think they were the most amazing superfood you could possibly eat.

I even recommended them to my patients…

Until I found this out: 🧵
Many avocados are artificially ripened.

They’re placed in gas chambers and treated with ethylene gas to speed up the process.

But this prevents natural flavor compounds and phytonutrients from developing.

It may look perfect outside, but it lacks quality inside.
Now let’s talk about avocado oil.

A study of 22 major brands revealed alarming findings:

• High oxidation levels (causing inflammation)
• Oils diluted with soy or canola
• Some products contained 0% avocado oil

82% of avocado oil on shelves is not what it claims to be. Image
Why oxidation matters:

Oxidized oil becomes harmful & causes inflammation.

Just like a cut apple turns brown, avocado oil goes rancid when exposed to air, heat, or light.

You can’t taste it, but it is still there and damaging your body at a cellular level.

And it gets worse…
There are no official U.S. regulations for avocado oil.

Unlike olive oil, which has international standards, avocado oil can be diluted, deodorized, or mislabeled with no legal consequences.

Some bottles don’t even list an expiration date.

So how can you protect yourself?
How to protect yourself:
• Choose dark glass bottles
• Check for a harvest date & expiration date
• Avoid the cheapest brands
• Fresh oil should have a slight green tint

Keep in mind: “Product of USA” may still be grown in China, blended in Mexico, bottled in the U.S.
What about guacamole?

Most fast-food guacamole contains less than 5% avocado, and sometimes none at all.

It’s often replaced with:
• Green peas
• Hydrogenated oils
• Starches and fillers

What you’re actually eating is mostly green goo.
Even skincare products can be misleading.

Many “avocado oil” creams list soy, palm, or mineral oil first.

The avocado oil is often just a trace amount, added for marketing purposes.
How to pick real avocados:
• Choose ripe, firm fruit
• Avoid shiny, wax-coated ones
• Test ripeness with a gentle thumb press

When selected properly, avocados are highly nutritious, packed with potassium, magnesium, and healthy fats. Image
One medium avocado provides up to 900 mg of potassium, essential for muscle, nerve, and heart function.

They’re also rich in magnesium and have far less omega-6 than seed oils.

But these benefits only apply to real, properly ripened avocados.
Avocados are still one of the best foods out there when chosen carefully.

They provide healthy fats, potassium, magnesium, and support overall health.

“Oatmeal is the healthiest food you can eat for breakfast.”

That’s what many people believe.

But the truth? Oatmeal isn’t as healthy as you might think. Here’s why: 🧵
I used to eat oatmeal every morning.

It’s marketed as heart-healthy, blood sugar-friendly, even a ‘superfood.’

But after reviewing the research, I found 3 major problems with oatmeal that most people have never heard of.
1/ Oatmeal and blood sugar

Studies often claim oats “improve” cholesterol and glucose.

The catch? They’re only being compared to white bread.

Oats may cause a smaller spike, but they still raise blood sugar.

That’s not truly blood sugar friendly.

Autophagy acts as your body’s anti-aging cleaning system.

It essentially eats the “junk” in your cells and converts it into usable material.

Here are 7 ways to naturally increase autophagy: 🧵
Autophagy occurs inside your cells.

It breaks down old proteins, damaged mitochondria, and accumulated cellular debris.

This process not only removes waste but also converts it into material that your body can use to build healthier cells.
Autophagy is one of the most important processes for cellular renewal.

Your body performs autophagy naturally, but to maximize its benefits, you need the right triggers.

Here are the seven most effective ways to increase it:

When you think of “healthy food,” what comes to mind?

Can you guess what I would think of?

Here are 7 of the healthiest foods you can eat, and why they are so beneficial: 🧵
What defines a healthy food?

One that:
• Is low in carbohydrates
• Is nutrient-dense
• Supports gut health
• Minimizes insulin spikes
• Provides essential fats and phytonutrients

Foods that excessively raise insulin levels or deplete nutrients can negatively impact health.
Only two categories of food do not trigger an insulin response. These are:

• Fiber
• Fat

Lean, low-fat protein can cause significant insulin spikes.

An ideal diet incorporates high-fiber, high-fat, nutrient-dense foods.

Now let’s explore the 7 healthiest foods you can eat…

The most dangerous place for fat to build up isn’t your belly.

It’s your arteries.

Here are 4 foods that can help keep them clean and protect your heart: 🧵
Plaque in arteries isn’t just cholesterol.

It’s a mix of:
• Calcium
• Protein
• Cholesterol

Inside plaque, researchers often find biofilms: colonies of harmful microbes protected by calcium.

So why does plaque form?
Plaque forms where arteries are damaged or inflamed.

This damage usually comes from:
• Sugar and refined carbs
• Seed oils (omega-6)
• Alcohol and junk food
• Diabetes and insulin resistance

That’s what allows calcium and LDL to harden inside arteries.

These 3 foods DAMAGE your kidneys with every bite...

Most people have no idea.

Here’s what they are... and what to eat instead: 🧵
Your kidneys are incredible.

Each one contains a million tiny filters called nephrons.

Together, they filter 50 gallons of blood per day, recycling 99% of it.

But certain everyday foods silently destroy them. Here are some of the most damaging…
1/ Fried chicken (fast food style)

Fried in seed oils at high heat, then coated in flour.
This combination creates glycation, which is sugar binding to protein.

The result? Damaged proteins that clog the kidneys, raise A1C, and worsen diabetic symptoms. Image

It’s hard to know which supplements and foods actually help your body and which are just hype.

Here’s how I’d rate some popular ones on a scale from 1 to 10:

1/ Ashwagandha: 🧵
8
Ashwagandha is highly effective at managing stress and cortisol. It can help calm the body and support overall adrenal health.

2/ Black seed oil: 10
Black seed oil is incredibly versatile. It supports the immune system, helps maintain a healthy inflammatory response, and promotes healthy skin and hair.
3/ Probiotics: 9-10
Quality matters. L. reuteri is one of the best strains for supporting a healthy microbiome.

4/ Electrolytes: 8
Many electrolyte formulas are low in potassium and contain hidden maltodextrin. Good ones include enough potassium, magnesium, and sea salt.
