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.

‘Brave’ doesn’t always feel like certain, or strong, or ready. In fact, it rarely does. That what makes it brave.♥️

We teach our kids to respect adults and other children, and they should – respect is an important part of growing up to be a pretty great human. There’s something else though that’s even more important – teaching them to respect themselves first. 

We can’t stop difficult people coming into their lives. They might be teachers, coaches, peers, and eventually, colleagues, or perhaps people connected to the people who love them. What we can do though is give our kids independence of mind and permission to recognise that person and their behaviour as unacceptable to them. We can teach our kids that being kind and respectful doesn’t necessarily mean accepting someone’s behaviour, beliefs or influence. 

The kindness and respect we teach our children to show to others should never be used against them by those broken others who might do harm. We have to recognise as adults that the words and attitudes directed to our children can be just as damaging as anything physical. 

If the behaviour is from an adult, it’s up to us to guard our child’s safe space in the world even harder. That might be by withdrawing support for the adult, using our own voice with the adult to elevate our child’s, asking our child what they need and how we can help, helping them find their voice, withdrawing them from the environment. 

Of course there will be times our children do or say things that aren’t okay, but this never makes it okay for any adult in your child’s life to treat them in a way that leads them to feeling ‘less than’.

Sometimes the difficult person will be a peer. There is no ‘one certain way’ to deal with this. Sometimes it will involve mediation, role playing responses, clarifying the other child’s behaviour, asking for support from other adults in the environment, or letting go of the friendship.

Learning that it’s okay to let go of relationships is such an important part of full living. Too often we hold on to people who don’t deserve us. Not everyone who comes into our lives is meant to stay and if we can help our children start to think about this when they’re young, they’ll be so much more empowered and deliberate in their relationships when they’re older.♥️
When we are angry, there will always be another emotion underneath it. It is this way for all of us. 

Anger itself is a valid emotion so it’s important not to dismiss it. Emotion is e-motion - energy in motion. It has to find a way out, which is why telling an angry child to calm down or to keep their bodies still will only make things worse for them. They might comply, but their bodies will still be in a state of distress. 

Often, beneath an angry child is an anxious one needing our help. It’s the ‘fight’ part of the fight or flight response. As with all emotions, anger has a job to do - to help us to safety through movement, or to recruit support, or to give us the physical resources to meet a need or to change something that needs changing. It doesn’t mean it does the job well, because an angry brain means the feeling brain has the baton, while the thinking brain sits out for a while. What it means is that there is a valid need there and this young person is doing their very best to meet it, given their available resources in the moment or their developmental stage. 

Children need the same thing we all need when we’re feeling fierce - to be seen,  heard, and supported; to find a way to get the energy out, either with words or movement. Not to be shut down or ‘fixed’. 

Our job isn’t to stop their anger, but to help them find ways to feel it and express it in ways that don’t do damage. This will take lots of experience, and lots of time - and that’s okay.♥️
The SCCR Online Conference 2021 is a wonderful initiative by @sccrcentre (Scottish Centre for Conflict Resolution) which will explore ’The Power of Reconnection’. I’ve been working with SCCR for many years. They do incredible work to build relationships between young people and the important adults around them, and I’m excited to be working with them again as part of this conference.

More than ever, relationships matter. They heal, provide a buffer against stress, and make the world feel a little softer and safer for our young people. Building meaningful connections can take time, and even the strongest relationships can feel the effects of disconnection from time to time. As part of this free webinar, I’ll be talking about the power of attachment relationships, and ways to build relationships with the children and teens in your life that protect, strengthen, and heal. 

The workshop will be on Monday 11 October at 7pm Brisbane, Australia time (10am Scotland time). The link to register is in my story.
There are many things that can send a nervous system into distress. These can include physiological (tired, hungry, unwell), sensory overload/ underload, real or perceived threat (anxiety), stressed resources (having to share, pay attention, learn new things, putting a lid on what they really think or want - the things that can send any of us to the end of ourselves).

Most of the time it’s developmental - the grown up brain is being built and still has a way to go. Like all beautiful, strong, important things, brains take time to build. The part of the brain that has a heavy hand in regulation launches into its big developmental window when kids are about 6 years old. It won’t be fully done developing until mid-late 20s. This is a great thing - it means we have a wide window of influence, and there is no hurry.

Like any building work, on the way to completion things will get messy sometimes - and that’s okay. It’s not a reflection of your young one and it’s not a reflection of your parenting. It’s a reflection of a brain in the midst of a build. It’s wondrous and fascinating and frustrating and maddening - it’s all the things.

The messy times are part of their development, not glitches in it. They are how it’s meant to be. They are important opportunities for us to influence their growth. It’s just how it happens. We have to be careful not to judge our children or ourselves because of these messy times, or let the judgement of others fill the space where love, curiosity, and gentle guidance should be. For sure, some days this will be easy, and some days it will feel harder - like splitting an atom with an axe kind of hard.

Their growth will always be best nurtured in the calm, loving space beside us. It won’t happen through punishment, ever. Consequences have a place if they make sense and are delivered in a way that doesn’t shame or separate them from us, either physically or emotionally. The best ‘consequence’ is the conversation with you in a space that is held by your warm loving strong presence, in a way that makes it safe for both of you to be curious, explore options, and understand what happened.♥️
