Many of us are looking for ways to eat a healthier and more sustainable diet. And one way to do this is by reducing the amount of meat we eat.

That doesn’t mean you need to become a vegan or vegetarian. Our recent research shows even small changes to cut down on meat consumption could help improve health and wellbeing.

But not all plant-based options are created equal and some are ultra-processed. Navigating what’s available when eating out – including options like tofu and fake meats – can be a challenge.

So what are your best options at a cafe or restaurant? Here are some guiding principles to keep in mind when cutting down on meat.

Health benefits to cutting down

Small amounts of lean meat can be part of a healthy, balanced diet. But the majority of Australians still eat more meat than recommended.

Only a small percentage of Australians (10%) are vegetarian or vegan. But an increasing number opt for a flexitarian diet. Flexitarians eat a diet rich in fruits and vegetables, while still enjoying small amounts of meat, dairy, eggs and fish.

Our recent research looked at whether the average Australian diet would improve if we swapped meat and dairy for plant-based alternatives, and the results were promising.

The study found health benefits when people halved the amount of meat and dairy they ate and replaced them with healthy plant-based foods, like tofu or legumes. On average, their dietary fibre intake – which helps with feeling fuller for longer and digestive health – went up. Saturated fats – which increase our blood cholesterol levels, a risk factor for heart disease – went down.

Including more fibre and less saturated fat helps reduce the risk of heart disease.

Achieving these health benefits may be as simple as swapping ham for baked beans in a toastie for lunch, or substituting half of the mince in your bolognese for lentils at dinner.

How it’s made matters

For a long time we’ve known processed meats – such as ham, bacon and sausages – are bad for your health. Eating high amounts of these foods is associated with poor heart health and some forms of cancer.

But the same can be true of many processed meat alternatives.

Plant-based alternatives designed to mimic meat, such as sausages and burgers, have become readily available in supermarkets, cafes and restaurants. These products are ultra-processed and can be high in salt and saturated fat.

Our study found when people replaced meat and dairy with ultra-processed meat alternatives – such as plant-based burgers or sausages – they ate more salt and less calcium, compared to eating meat or healthy plant-based options.

So if you’re cutting down on meat for health reasons, it’s important to think about what you’re replacing it with. The Australian Dietary Guidelines recommend eggs, legumes/beans, tofu, nuts and seeds.

Tofu can be a great option. But we recommend flavouring plain tofu with herbs and spices yourself, as pre-marinated products are often ultra-processed and can be high in salt.

What about when dining out?

When you’re making your own food, it’s easier to adapt recipes or reduce the amount of meat. But when faced with a menu, it can be difficult to work out what is the best option.

Here are our four ways to make healthy choices when you eat out:

1. Fill half your plate with vegetables

When cutting down on meat, aim for half your plate to be vegetables. Try to also eat a variety of colours, such as leafy green spinach, red capsicum and pumpkin.

When you’re out, this might look like choosing a vegetable-based entree, a stir-fry or ordering a side salad to have with your meal.

2. Avoid the deep fryer

The Australian Dietary Guidelines recommend limiting deep fried foods to once a week or less. When dining out, choose plant-based options that are sautéed, grilled, baked, steamed, boiled or poached – instead of those that are crumbed or battered before deep frying.

This could mean choosing vegetarian dumplings that are steamed not fried, or poached eggs at brunch instead of fried. Ordering a side of roast vegetables instead of hot chips is also a great option.

3. Pick wholegrains

Scan the menu for wholegrain options such as brown rice, wholemeal pizza or pasta, barley, quinoa or wholemeal burger buns. Not only are they good sources of protein, but they also provide more dietary fibre than refined grains, which help keep you fuller for longer.

4. If you do pick meat – choose less processed kinds

You may not always want, or be able, to make a vegetarian choice when eating out and with other people. If you do opt for meat, it’s better to steer clear of processed options like bacon or sausages.

If sharing dishes with other people, you could try adding unprocessed plant-based options into the mix. For example, a curry with lentils or chickpeas, or a vegetable-based pizza instead of one with ham or salami. If that’s not an option, try choose meat that’s a lean cut, such as chicken breast, or options which are grilled rather than fried.

Sea moss is the latest “superfood” wellness influencers are swearing by. They claim sea moss products – usually in gel form – have multiple health benefits. These include supporting brain and immune function, or protecting against viruses and other microbes.

But do these health claims stack up? Let’s take a look.

What is sea moss?

Sea moss is produced using a kind of seaweed – particularly red algae – that grow in various locations all around the world. Three main species are used in sea moss products:

• Chondrus crispus (known as Irish moss or carrageenan moss)
• Eucheuma cottonii (sea moss or seabird’s nest)
• Gracilaria (Irish moss or ogonori).

Some products also contain the brown algae Fucus vesiculosus (commonly known as bladderwrack, black tang, rockweed, sea grapes, bladder fucus, sea oak, cut weed, dyers fucus, red fucus or rock wrack).

Most sea moss products are sold as a gel that can be added to recipes, used in smoothies, frozen into ice cubes or eaten on its own. The products also come in capsule form or can be purchased “raw” and used to make your own gels at home.

What’s the evidence?

Sea moss products claim a host of potential health benefits, from supporting immunity, to promoting skin health and enhancing mood and focus, among many others.

But is there any evidence supporting these claims?

Recent studies have reviewed the biological properties of the main sea moss species (Chondrus crispus, Eucheuma cottonii, Gracilaria and Fucus vesiculosus).

They suggest these species may have anti-inflammatory, antioxidant, anticancer, antidiabetic and probiotic properties.

However, the vast majority of research relating to Chondrus crispus, Gracilaria and Fucus vesiculosus – and all of the research on Eucheuma cottonii – comes from studies done in test tubes or using cell and animal models. We should not assume the health effects seen would be the same in humans.

In cell and animal studies, researchers usually administer algae in a laboratory and use specific extracts rich in bioactive compounds rather than commercially available sea moss products.

They also use very different – often relatively larger – amounts compared to what someone would typically consume when they eat sea moss products.

This means the existing studies can’t tell us about the human body’s processes when eating and digesting sea moss.

Sea moss may have similar effects in humans. But so far there is very little evidence people who consume sea moss will experience any of the claimed health benefits.

Nutritional value

Eating sea moss does not replace the need for a balanced diet, including a variety of fruits and vegetables.

Chondrus crispus, Eucheuma cottonii and Gracilaria, like many seaweeds, are rich sources of nutrients such as fatty acids, amino acids, vitamin C and minerals. These nutrients are also likely to be present in sea moss, although some may be lost during the preparation of the product (for example, soaking may reduce vitamin C content), and those that remain could be present in relatively low quantities.

There are claims that sea moss may be harmful for people with thyroid problems. This relates to the relationship between thyroid function and iodine. The algae used to make sea moss are notable sources of iodine and excess iodine intake can contribute to thyroid problems, particularly for people with pre-existing conditions. That is why these products often carry disclaimers related to iodine sensitivity or thyroid health.

Is it worth it?

So you may be wondering if it’s worth trying sea moss. Here are a few things to consider before you decide whether to start scooping sea moss into your smoothies.

A 375mL jar costs around $A25–$30 and lasts about seven to ten days, if you follow the recommended serving suggestion of two tablespoons per day. This makes it a relatively expensive source of nutrients.

Sea moss is often hyped for containing 92 different minerals. While there may be 92 minerals present, the amount of minerals in the algae will vary depending on growing location and conditions.

The efficiency with which minerals from algae can be absorbed and used by the body also varies for different minerals. For example, sodium is absorbed well, while only about 50% of iodine is absorbed.

But sea moss has also been shown to contain lead, mercury and other heavy metals – as well as radioactive elements (such as radon) that can be harmful to humans. Seaweeds are known for their ability to accumulate minerals from their environment, regardless of whether these are beneficial or harmful for human nutrition. Remember, more doesn’t always mean better.

What else am I eating?

While you won’t get a full nutritional breakdown on the jar, it is always wise to check what other ingredients you may be eating. Sea moss products can contain a range of other ingredients, such as lime, monk fruit powder, spirulina and ginger, among many others.

These ingredients differ between brands and products, so be aware of your needs and always check.

Despite their health claims, most sea moss products also carry disclaimers indicating that the products are not intended to diagnose, treat, cure or prevent any disease.

If you have concerns about your health, always speak to a health professional for accurate and personalised medical advice.
