It's well established that being at our healthiest means eating a balanced diet – plenty of fruit and vegetables (at least five portions a day), balanced with starchy wholegrain carbohydrates, lean protein, and a little unsaturated fat.
For years, a diet built around meat, potatoes and vegetables was considered a solid way to achieve that balance. More recent research, however, shows that eating meat – particularly red or processed meat – regularly and in excess can contribute to chronic health conditions.
The Problem with Meat
Red meat (beef, lamb) and processed meats (sausages, burgers, bacon, ham) provide protein, vitamins and minerals, but also come with saturated fat and cholesterol. UK guidelines recommend limiting red and processed meat to around 70g a day, no more than three times a week – for context, three thin slices from a roast dinner, each roughly the size of half a slice of bread, add up to around 90g.
Eating more than the recommended amount has been linked to increased risk of obesity, high cholesterol, high blood pressure, heart disease and type 2 diabetes. Regular consumption of red and processed meat is also associated with increased colorectal cancer risk, which led the World Health Organisation to classify processed meat as a carcinogen and red meat as a probable carcinogen.
Beyond individual health, meat production – including poultry – has a significant environmental impact, with animal agriculture contributing substantially to greenhouse gas emissions.
Reducing how much meat you eat can meaningfully lower your environmental footprint alongside supporting your own health. If you notice digestive discomfort, bloating or fatigue specifically after eating red meat, it's also worth knowing that this can sometimes point to a genuine red meat intolerance or allergy, which is a different issue from the general health guidance above and worth investigating separately if it applies to you.
What Can I Eat Instead of Meat?
Meat is primarily valued as a protein source – needed for energy, and for muscle growth and repair. If you're cutting back, it's worth thinking about where that protein will come from instead.
Low-fat dairy and eggs provide protein without as much saturated fat. Plant-based foods are also a stronger protein source than many people realise – peas, beans, chickpeas, lentils, nuts and seeds are all genuinely protein-rich, as are many vegetarian or vegan meat alternatives (mince, sausages, burgers), which tend to be considerably lower in fat and free from cholesterol.
You don't need to give up meat entirely or become an expert with a tin of chickpeas overnight. Simply having a few meat-free days a week is a manageable starting point – "Meat Free Monday" has become popular with families looking to eat more healthily, and supermarket shelves are increasingly stocked with meat-free alternatives and inspiration as plant-based eating grows in popularity.
Making vegetables and plant-based protein the main event in more of your meals is often easier than expected, and both your health and the environment benefit from it.
