The Remarkable Effect of This On the Brain

The Remarkable Effect of This Diet on the Brain

It’s no secret that a diet high in fat can cause trouble to the body, but new research has discovered that the brain can also get caught up in the mess. 

One of the ways the brain keeps prime performance is through the work of the immune cells. They bustle around the brain like scavengers, getting rid of damaged cells or infectious agents in the brain. 

These immune cells are important for healthy brain function, but when a diet is so high in fat as to cause obesity, they stop bustling and start eating the connections between neurons. 

Too much fat in the body seems to cause chronic inflammation, which triggers these immune cells to have an autoimmune response. They stop mopping up toxins and instead turn on their own healthy brain cells. The fallout from this includes a reduced capacity to learn as efficiently.

According to researcher and neuroscientist Dr Alexis M. Stranahan, immune cells ‘eating synapses is contributing to synapse loss and cognitive impairment in obesity.’

It’s a scary prospect, but the damage is completely reversible. Changing to a low-fat diet for two months can reverse the damage completely and restore healthy cognitive function.

The research was conducted using two groups of male mice. (Mice are commonly used in research for their  biological and genetic similarity to humans.) One group ate a diet that was 10% fat, the other group ate a diet that was 60% fat. The human version of these diets would be along the lines of a healthy diet versus a fast-food diet.

After eight weeks, the mice on the high-fat diet were fatter – no surprises there – but they were similar to the mice in the low-fat group in terms of brain changes and other physiological measures.

At 12 weeks, the differences between the groups started to show themselves. The high fat mice were obese and there was evidence of reduced brain function.

At this point, half the mice in the high fat group were then placed on the low-fat diet. After about two months, their weight returned to normal, but they had a larger fat pad than their peers, making them a little more vulnerable to weight gain in the future.

The mice that remained on the high fat diet continued to get fatter, and the scavenger cells and neurons in their brain continued to wither.

As explained by Stranahan, ‘Instead of doing garbage disposal, they are taking your mailbox, your front door, your kitchen sink and all the stuff that you need, and not doing their job of getting rid of trash.’

This research is compelling and is further evidence of the way the body and mind are deeply connected. The health of the body will ultimately affect the health of the mind. Obesity is stealing people from the lives they deserve to be living and from the people who love them. What we now know is that it is also stealing the capacity for people to learn and grow and reach their fullest potential. That affects all of us.

Food is meant to be fun, and it’s important to remember that the effect of fat on the brain uncovered by this research didn’t start to emerge until the point of obesity. In the same way that any unhealthy relationship – with people, work, exercise , anything – will cause problems, an unhealthy relationship will food will also bring us undone. The good news it that this is completely reversible. It’s not often we have the problem and the easy solution in one easy package. Thanks science.

Love this site! The articles are articulate and explained very clearly. Very relevant to the reality of parenthood, especially when we all have our own baggage from our own upbringing.
These articles serves as a kind reminder to be mindful. Thank you.

This goes against everything that I am reading that fat is actually incredibly beneficial for the brain. Of course not all fats are created equal and there are definitely good fats like fish oil, and pasture butter, and coconut oil and bad fats such as the unstable fats industrialized seed oils and hydrogenated oils (that we were told were healthy). See Dr. David Perlmutter ‘s book Brain Maker.

Some fats are really healthy and essential for brain health, in particular the fats found in oily fish like salmon, walnuts and the other foods you refer to. You’ll see from the article that the study is referring to fat of the type and quantity that leads to obesity.

Could you put a copy or link to the Research article for further reading. I would like a clearer understanding of the diet that was used.

I have spoken about this to all my “college” students. I found out that for them, the taste is ” stronger” than “quality and nutrition” in food. So they go for the “taste.”

Disappointing, especially when people are intelligent but still make decisions based on their “emotions” rather than wisdom.

Hey Sigmund

Yes, absolutely. The problem is that the things that are being added to our food for taste are all sorts of unhealthy, and we probably don’t know the extent of what they can do. If this is what excessive fat does to the brain, we can only wonder what other things are doing. I expect we’ll see some interesting research on this.

How does high sugar affect the brain?

Although many foods are “low fat”, they are LOADED with either high fructose sugar or artificial sweeteners.

Sugar causes weight gain too, but is it a different type of fat from that of “high” fat foods? Is the affect on the brain the same using sweeteners the same?

Reply
Hey Sigmund

You’re absolutely right. Our food is loaded with so many things other than fat that cause weight gain. This research specifically looked at the effect of high fat on the brain, so the results are specific to that. It’s early days and there will no doubt be more research to come. I expect that future lines of research will explore the effects of other things, such as sugar, on the brain. It will be really interesting to see what we learn from this.

Let them know …

Anxiety shows up to check that you’re okay, not to tell you that you’re not. It’s your brain’s way of saying, ‘Not sure - there might be some trouble here, but there might not be, but just in case you should be ready for it if it comes, which it might not – but just in case you’d better be ready to run or fight – but it might be totally fine.’ Brains can be so confusing sometimes! 

You have a brain that is strong, healthy and hardworking. It’s magnificent and it’s doing a brilliant job of doing exactly what brains are meant to do – keep you alive. 

Your brain is fabulous, but it needs you to be the boss. Here’s how. When you feel anxious, ask yourself two questions:

- ‘Do I feel like this because I’m in danger or because there’s something brave or important I need to do?’

- Then, ‘Is this a time for me to be safe (sometimes it might be) or is this a time for me to be brave?

And remember, you will always have ‘brave’ in you, and anxiety doesn’t change that a bit.♥️

The temptation to fix their big feelings can be seismic. Often this is connected to needing to ease our own discomfort at their discomfort, which is so very normal.

Big feelings in them are meant to raise (sometimes big) feelings in us. This is all a healthy part of the attachment system. It happens to mobilise us to respond to their distress, or to protect them if their distress is in response to danger.

Emotion is energy in motion. We don’t want to bury it, stop it, smother it, and we don’t need to fix it. What we need to do is make a safe passage for it to move through them. 

Think of emotion like a river. Our job is to hold the ground strong and steady at the banks so the river can move safely, without bursting the banks.

However hard that river is racing, they need to know we can be with the river (the emotion), be with them, and handle it. This might feel or look like you aren’t doing anything, but actually it’s everything.

The safety that comes from you being the strong, steady presence that can lovingly contain their big feelings will let the emotional energy move through them and bring the brain back to calm.

Eventually, when they have lots of experience of us doing this with them, they will learn to do it for themselves, but that will take time and experience. The experience happens every time you hold them steady through their feelings. 

This doesn’t mean ignoring big behaviour. For them, this can feel too much like bursting through the banks, which won’t feel safe. Sometimes you might need to recall the boundary and let them know where the edges are, while at the same time letting them see that you can handle the big of the feeling. Its about loving and leading all at once. ‘It’s okay to be angry. It’s not okay to use those words at me.’

Ultimately, big feelings are a call for support. Sometimes support looks like breathing and being with. Sometimes it looks like showing them you can hold the boundary, even when they feel like they’re about to burst through it. And if they’re using spicy words to get us to back off, it might look like respecting their need for space but staying in reaching distance, ‘Ok, I’m right here whenever you need.’♥️
We all need certain things to feel safe enough to put ourselves into the world. Kids with anxiety have magic in them, every one of them, but until they have a felt sense of safety, it will often stay hidden.

‘Safety’ isn’t about what is actually safe or not, but about what they feel. At school, they might have the safest, most loving teacher in the safest, most loving school. This doesn’t mean they will feel enough relational safety straight away that will make it easier for them to do hard things. They can still do those hard things, but those things are going to feel bigger for a while. This is where they’ll need us and their other anchor adult to be patient, gentle, and persistent.

Children aren’t meant to feel safe with and take the lead from every adult. It’s not the adult’s role that makes the difference, but their relationship with the child.

Children are no different to us. Just because an adult tells them they’ll be okay, it doesn’t mean they’ll feel it or believe it. What they need is to be given time to actually experience the person as being safe, supportive and ready to catch them.

Relationship is key. The need for safety through relationship isn’t an ‘anxiety thing’. It’s a ‘human thing’. When we feel closer to the people around us, we can rise above the mountains in our way. When we feel someone really caring about us, we’re more likely to open up to their influence
and learn from them.

But we have to be patient. Even for teachers with big hearts and who undertand the importance of attachment relationships, it can take time.

Any adult at school can play an important part in helping a child feel safe – as long as that adult is loving, warm, and willing to do the work to connect with that child. It might be the librarian, the counsellor, the office person, a teacher aide. It doesn’t matter who, as long as it is someone who can be available for that child at dropoff or when feelings get big during the day and do little check-ins along the way.

A teacher, or any important adult can make a lasting difference by asking, ‘How do I build my relationship with this child so s/he trusts me when I say, ‘I’ve got you, and I know you can do this.’♥️
