An increasing number of office workers are opting to bring homemade lunches to work in response to rising food costs and a growing desire to eat healthier, according to recent research. Nearly half of employees report preparing packed lunches more frequently than a year ago, with 69 percent citing the expense of buying meals near the office as a primary reason.
Dr. Federica Amati, a registered public health nutritionist and nutrition lead at Imperial College London, highlights the advantages of home-packed lunches, both in terms of cost savings and nutritional control. She emphasizes that such meals do not need to be complicated or require extensive preparation early in the morning.
Dr. Amati outlines five key components of a balanced packed lunch. First, a sufficient source of protein is essential, typically from animal or plant sources such as chicken, fish, eggs, lentils, chickpeas, tofu, or feta cheese. A typical portion should provide between 25 to 40 grams of protein to promote satiety throughout the afternoon.
Second, dietary fibre plays a critical role. Incorporating legumes and intact whole grains—grains where the kernel remains visible, such as quinoa—can help individuals meet recommended daily fibre intake levels. Currently, UK adults consume an average of 20 grams when 30 grams per day is advised, and higher fibre intake is linked to lower risks of cardiovascular disease and type 2 diabetes.
Fats derived from plants and fish constitute the third element. Extra virgin olive oil, nuts, seeds, avocado, and oily fish not only enhance flavor but also aid in the absorption of fat-soluble nutrients. Dr. Amati cites a large dietary study demonstrating that a Mediterranean diet rich in olive oil or nuts reduced major cardiovascular events by approximately 30 percent. Adding a tablespoon of high-quality oil at the time of eating is a simple method to incorporate healthy fats.
Variety is the fourth principle. Consuming five or more different plant-based foods daily—including grains, legumes, vegetables, fruits, nuts, seeds, herbs, and spices—supports gut microbiome diversity and resilience. This diversity is linked to improved digestion and overall health.
The fifth recommended element is the inclusion of fermented foods such as sauerkraut, kimchi, live yogurt, or aged cheese. Emerging studies, including a small trial from Stanford Medicine, indicate that increased consumption of fermented foods can enhance gut microbiome diversity and reduce inflammation markers.
Dr. Amati also advises keeping a small stock of nutritious provisions at the workplace. Items such as mixed nuts and seeds provide beneficial fats, protein, and fibre, while wholegrain oatcakes or rye crispbreads serve as convenient bases for toppings like hummus, cottage cheese, or tinned fish. Long-lasting fruits like apples, pears, and bananas, alongside seasonings such as chilli flakes and za’atar, can provide added flavor and nutritional value.
This guidance reflects a broader trend of workers taking greater control over their diet as they balance budget constraints with the desire for healthier eating habits.
