Welcome back to another episode of Simple English Podcast.

I'm Lisa and today we have an important topic to talk, how the food we eat affects our brain.

I think most of us already know that food is fuel for our bodies.

But did you know it also affects how we think and feel?

To help us understand more about this, I've invited a Special guest today, Dr.

Adam, who's a nutrition expert and knows a lot about how our diet impacts brain function.

Don't forget to check out the free PDF file in the comment section below to get the full transcript and new vocabulary for this episode.

I'm excited to be here and to share some useful information with everyone.

Can you tell us in simple terms how what we eat actually affects our brain?

Our brain, just like the rest of our body, needs energy and nutrients to work properly.

If you don't put in good fuel, the engine won't run smoothly.

The food we eat provides the fuel that our brain uses to think, remember things and even manage our emotions.

So if I'm eating a lot of unhealthy food, will my brain have trouble working properly?

If you eat a lot of processed foods, things like chips, sugary snacks and fast food, it can slow down how your brain works.

These foods don't have the nutrients your brain needs.

Over time, eating this way can make it harder to concentrate, remember things, and

can even affect your mood, making you feel more anxious or sad.

So what kinds of foods should we eat to keep our brain in top shape?

There are plenty of brain friendly foods.

First, you want to focus on healthy fats, like the kind you find in fish, nuts and seeds.

Omega 3 fatty acids which are in salmon, flaxseeds and walnuts, are great for your brain.

They help build brain cells and keep them healthy.

Next, you should eat a variety of fruits and vegetables, especially colorful ones like berries, spinach and broccoli.

These are full of antioxidants which protect your brain from damage caused by free radicals.

Kinda like rust on metal, but in your brain.

I've heard people say you are what you eat, but

I didn't realize how true that is for our brain as well.

Are there any other nutrients we should focus on?

Another important one is protein, which you can get from things like eggs.

Proteins break down into amino acids, which help produce neurotransmitters, chemicals in your brain that manage how you feel and think.

Also, vitamins like B12 and folic acid are essential.

They're found in leafy greens, eggs and whole grains, and

they help keep your brain sharp as you get older.

It sounds like eating a balanced diet isn't just good for your body, but

Unfortunately, sugar can have a negative effect on brain function.

Too much sugar can lead to inflammation in the brain, which affects how your brain cells communicate.

if you eat too much, it can lead to problems like memory loss, mood swings, and

even increase the risk of conditions like depression over time.

That's a great reason to cut back on sugary snacks.

So basically, we need to focus on whole foods, healthy fats, free fruits, veggies, lean proteins, and

limit the junk food to keep our brain working well.

When you eat a variety of healthy foods, your brain gets everything it needs to function well and stay strong.

Alright, it's time for one of my favorite parts of the show, the fun fact.

Adam, do you have a fun fact for us today?

Did you know that your brain uses about 20% of the calories you consume each day?

Even though the brain makes up only about 2% of your body weight, it needs a lot of energy to keep you thinking, focusing, and

No wonder our food choices are so important for our brain.

It's working hard all day even when we don't realize it.

It's constantly active, even when you're sleeping.

This has been such an enlightening conversation.

Adam, thank you so much for breaking down how the food we eat affects our brain in such simple terms.

I'm glad to be here and share this information with everyone.

It's so important to know that what we eat not only affects our bodies, but

So to all our listeners, remember, next time you're making a meal or grabbing a snack, think about how it will fuel your brain.

A healthy diet isn't just good for your body, it helps your brain function better too.

Now it's time to learn some important vocabulary related to the topic.

Substances in food that help the body grow stay healthy and function properly.

Fruits and vegetables are rich in essential nutrients like vitamins and minerals.

Next word is omega 3 fatty acids a type of healthy fat that is important for brain function.

Found in fish, flaxseeds and walnuts, omega 3 fatty acids help protect brain cells and improve memory and focus.

Next word is Antioxidants Compounds that protect cells from damage caused by harmful molecules called free radicals.

Berries are full of antioxidants that keep the brain healthy and prevent cell damage.

Next word is Neurotransmitters Chemicals in the brain that transmit signals between nerve cells affecting mood and memory.

Proteins from eggs and beans help produce neurotransmitters essential for brain communication.

Next word is Inflammation the body's response to injury or harmful substances, which can also occur in the brain.

Excess sugar in the diet can cause inflammation in the brain, affecting memory and mood.
