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.

The need to feel connected to, and seen by our people is instinctive. 

THE FIX: Add in micro-connections to let them feel you seeing them, loving them, connecting with them, enjoying them:

‘I love being your mum.’
‘I love being your dad.’
‘I missed you today.’
‘I can’t wait to hang out with you at bedtime 
and read a story together.’

Or smiling at them, playing with them, 
sharing something funny, noticing something about them, ‘remembering when...’ with them.

And our adult loves need the same, as we need the same from them.♥️
Our kids need the same thing we do: to feel safe and loved through all feelings not just the convenient ones.

Gosh it’s hard though. I’ve never lost my (thinking) mind as much at anyone as I have with the people I love most in this world.

We’re human, not bricks, and even though we’re parents we still feel it big sometimes. Sometimes these feelings make it hard for us to be the people we want to be for our loves.

That’s the truth of it, and that’s the duality of being a parent. We love and we fury. We want to connect and we want to pull away. We hold it all together and sometimes we can’t.

None of this is about perfection. It’s about being human, and the best humans feel, argue, fight, reconnect, own our ‘stuff’. We keep working on growing and being more of our everythingness, just in kinder ways.

If we get it wrong, which we will, that’s okay. What’s important is the repair - as soon as we can and not selling it as their fault. Our reaction is our responsibility, not theirs. This might sound like, ‘I’m really sorry I yelled. You didn’t deserve that. I really want to hear what you have to say. Can we try again?’

Of course, none of this means ‘no boundaries’. What it means is adding warmth to the boundary. One without the other will feel unsafe - for them, us, and others.

This means making sure that we’ve claimed responsibility- the ability to respond to what’s happening. It doesn’t mean blame. It means recognising that when a young person is feeling big, they don’t have the resources to lead out of the turmoil, so we have to lead them out - not push them out.

Rather than focusing on what we want them to do, shift the focus to what we can do to bring felt safety and calm back into the space.

THEN when they’re calm talk about what’s happened, the repair, and what to do next time.

Discipline means ‘to teach’, not to punish. They will learn best when they are connected to you. Maybe there is a need for consequences, but these must be about repair and restoration. Punishment is pointless, harmful, and outdated.

Hold the boundary, add warmth. Don’t ask them to do WHEN they can’t do. Wait until they can hear you and work on what’s needed. There’s no hurry.♥️
Recently I chatted with @rebeccasparrow72 , host of ABC Listen’s brilliant podcast, ‘Parental as Anything: Teens’. I loved this chat. Bec asked all the questions that let us crack the topic right open. Our conversation was in response to a listener’s question, that I expect will be familiar to many parents in many homes. Have a listen here:

School refusal is escalating. Something that’s troubling me is the use of the word ‘school can’t’ when talking about kids.

Stay with me.

First, let’s be clear: school refusal isn’t about won’t. It’s about can’t. Not truly can’t but felt can’t. It’s about anxiety making school feel so unsafe for a child, avoidance feels like the only option.

Here’s the problem. Language is powerful, and when we put ‘can’t’ onto a child, it tells a deficiency story about the child.

But school refusal isn’t about the child.
It’s about the environment not feeling safe enough right now, or separation from a parent not feeling safe enough right now. The ‘can’t’ isn’t about the child. It’s about an environment that can’t support the need for felt safety - yet.

This can happen in even the most loving, supportive schools. All schools are full of anxiety triggers. They need to be because anything new, hard, brave, growthful will always come with potential threats - maybe failure, judgement, shame. Even if these are so unlikely, the brain won’t care. All it will read is ‘danger’.

Of course sometimes school actually isn’t safe. Maybe peer relationships are tricky. Maybe teachers are shouty and still using outdated ways to manage behaviour. Maybe sensory needs aren’t met.

Most of the time though it’s not actual threat but ’felt threat’.

The deficiency isn’t with the child. It’s with the environment. The question isn’t how do we get rid of their anxiety. It’s how do we make the environment feel safe enough so they can feel supported enough to handle the discomfort of their anxiety.

We can throw all the resources we want at the child, but:

- if the parent doesn’t believe the child is safe enough, cared for enough, capable enough; or

- if school can’t provide enough felt safety for the child (sensory accommodations, safe peer relationships, at least one predictable adult the child feels safe with and cared for by),

that child will not feel safe enough.

To help kids feel safe and happy at school, we have to recognise that it’s the environment that needs changing, not the child. This doesn’t mean the environment is wrong. It’s about making it feel more right for this child.♥️
Such a beautiful 60 second wrap of my night with parents and carers in Hastings, New Zealand talking about building courage and resilience in young people. Because that’s how courage happens - it builds, little bit by little bit, and never feeling like ‘brave’ but as anxiety. Thank you @healhealthandwellbeing for bringing us together happen.♥️
