Anorexia nervosa is a severe mental health disorder where people fear weight gain. Those with the disorder have distorted body image and hold rigid beliefs their body is too big. They typically manage this through restricted eating, leading to the serious medical consequences of malnutrition.

Anorexia has one of the highest death rates of any mental illness. Yet there are currently no effective drug treatments and the outcomes of psychotherapy (talk therapy) are poor. So we’re desperately in need of new and improved treatments.

Psilocybin, commonly known as magic mushrooms, is one such novel treatment. But while it shows early promise, you won’t see it used in clinical practice just yet – more research is needed to test if it’s safe and effective.

What does treatment involve?

The treatment involves the patient taking a dose of psilocybin in a safe environment, which is usually a specifically set up clinic. The patient undergoes preparation therapy before the dosing session and integration therapy after.

Psilocybin, extracted from mushrooms, is a psychedelic, which means it can produce altered thinking, sense of time and emotions, and can often result in hallucinations. It also has the potential to shift patients out of their rigid thinking patterns.

Psilocybin is not administered alone but instead with combined structured psychotherapy sessions to help the patient make sense of their experiences and the changes to their thinking. This is an important part of the treatment.

What does the research show?

Research has shown improved effects of psilocybin-assisted psychotherapy after one or two dosing sessions, a couple of weeks apart. Most research to date has targeted depression.

Psilocybin has been found to increase cognitive flexibility – our ability to adjust our thinking patterns according to changing environments or demands. This is one of the ways researchers believe psilocybin might improve symptoms for conditions such as depression and alcohol use disorder, which are marked by rigid thinking styles.

People with anorexia similarly struggle with rigid thinking patterns. So researchers and clinicians have recently turned their attention to anorexia.

In 2023, a small pilot study of ten women with anorexia was published in the journal Nature Medicine. It showed psilocybin-assisted psychotherapy (with 25mg of psilocybin) was safe and acceptable. There were no significant side effects and participants reported having valuable experiences.

Although the trial was not a formal efficacy trial, 40% of the patients did have significant drops in their eating disorder behaviour.

However, the trial only had one dosing session and no long-term follow up, so further research is needed.

A recent animal study using rats examined whether rigid thinking could be improved in rats when given psilocybin. After the psilocybin, rats gained weight and had more flexible thinking (using a reversal learning task).

These positive changes were related to the serotonin neurotransmitter system, which regulates mood, behaviour and satiety (feeling full).

Brain imaging studies in humans show serotonin disturbances in people with anorexia. Psilocybin-assisted psychotherapy is showing promise at modifying the serotonin disturbances and cognitive inflexibility that have been shown to be problematic in anorexia.

Research with animals can provide unique insights into the brain which can sometimes not be investigated in living humans. But animal models can never truly mimic human behaviour and the complex nature of chronic mental health conditions.

What’s next for research?

Further clinical trials in humans are very much needed – and are underway from a research team at the University of Sydney and ours at Swinburne.

Our trial will involve an initial 5mg dose followed by two subsequent doses of 25mg, several weeks apart. An initial low dose aims to help participants prepare for what is likely to be a new and somewhat unpredictable experience.

Our trial will examine the usefulness of providing psychotherapy that directly addresses body image disturbance. We are also investigating if including a family member or close friend in the treatment increases support for their loved one.

Data from other mental health conditions has suggested that not everyone sees benefits, with some people having bad trips and a deterioration in their mental health. So this treatment won’t be for everyone. It’s important to work out who is most likely to respond and under what conditions.

New trials and those underway will be critical in understanding whether psilocybin-assisted psychotherapy is a safe and effective treatment for anorexia, and the optimal conditions to improve the patient’s response. But we are some way off from seeing this treatment in the clinic. One of the big issues being the cost of this intervention and how this will be funded.

You might remember cottage cheese from your childhood. Back then, it was considered “diet food”. You ate it out of the tub, with celery or spread it on crackers for a low-calorie snack. Then cottage cheese went out of fashion.

But cottage cheese is having a resurgence. In recent months, Google searches for “cottage cheese” have risen to the highest levels since 2004.

Social media influencers have been promoting its benefits on TikTok and Instagram with hashtags such as #cottagecheese, #cottagecheeseforlife, and #cottagecheeserecipe. Sales of cottage cheese around the world have skyrocketed.

Let’s see why cottage cheese is having such a moment.

What is cottage cheese?

Cottage cheese is a fresh dairy cheese product with a mild flavour and a slightly tangy taste. It is made by curdling cow’s milk, then draining the whey, leaving behind the curds. These curds are usually small and lumpy, and the texture can vary from creamy to dry, depending on the amount of whey left in the cheese.

The term “cottage cheese” is said to have originated because the cheese was generally made in cottage-type houses from leftover milk, after making butter.

Cottage cheese is cheap, costing about A$12 per kilogram in the supermarket, similar to ricotta cheese.

It’s also surprisingly simple to make at home using freely available recipes. All you need is milk, salt and a splash of vinegar.

We’re using cottage cheese in new ways

It’s difficult to know what started the latest cottage cheese trend. But the creativity of social media means people are sharing alternative ways to use cottage cheese, changing people’s views from it being boring and lacking flavour to it being versatile and healthy.

People are spreading cottage cheese on toast and using it to make dishes such as porridge, dips, salads, bread and flatbreads. They’re using it in cakes and scones, and in desserts such as mousse and ice cream.

Is cottage cheese healthy?

Compared with other cheeses, cottage cheese is low in fat and therefore energy (kilojoules or kJ). This makes it a smart choice for people looking to cut down on their daily energy intake.

For example, 100 grams of cottage cheese contains about 556kJ. The same amount of cheddar contains 1,254kJ and parmesan 1,565kJ.

Many cheeses are rich in protein but they often contain higher amounts of kilojoules due to their fat content. But cottage cheese has substantial amounts of protein with fewer kilojoules.

This makes cottage cheese an ideal option for people aiming to maximise their protein intake without eating large amounts of kilojoules.

Some 100g of cottage cheese provides 17g protein. This is about the same found in three eggs, 60g chicken breast or 320 millilitres (about 300g) full-fat yoghurt.

Cottage cheese also contains high levels of vitamin B12 (important for healthy brain function), riboflavin (supports healthy skin and eyes), phosphorus (helps build strong bones and teeth) and folate (essential for cell growth).

However, cottage cheese is lower in calcium compared with other cheeses. It contains just 89 milligrams per 100g. This compares with parmesan (948mg), haloumi (620mg) and ricotta (170mg).

You’ve convinced me. How can I use cottage cheese?

Beyond its excellent nutrition profile, the resurgence of cottage cheese is enabling people to experiment in the kitchen. Its neutral flavour and varied textures – ranging from smooth to chunky – makes it suitable for a range of dishes, from sweet to savoury.

TikTok and Instagram have some great recipes. You could start with an old faithful recipe of celery and cottage cheese, and work your way towards new options such as cottage cheese ice cream.

The healthiest recipes will be those that combine cottage cheese with wholefoods such as fruits, vegetables, nuts and seeds, and lean protein sources.

For instance, you can make a cottage cheese wrap then fill it with vegetables and a lean source of protein (such as chicken or fish).

Other combinations include cottage cheese salad dressings, vegetable dips and egg salads.

Cottage cheese’s rise in popularity is well deserved. Including more cottage cheese in your diet is a smart choice for getting a high dose of protein without adding processed ingredients or too much energy. Embrace the trend and get creative in the kitchen.
