Brits eat 11.5 billion sandwiches a year but two slices of white bread has around 200 calories. Sandwich options from the most popular diets include Vegan, Gluten- free, Raw, Paleo and the Dopamine diet.

Vegan Sandwich

A Vegan diet means no animal products at all, including butter, eggs and dairy.

Bread is normally vegan, except products like brioche which may contain eggs.

But if you’re on a vegan diet, you may struggle to get enough vitamin B12 which is only found naturally in animal products. A vitamin B12 deficiency can result in anaemia and even depression.

To supplement your vitamin B12 intake, Marmite is a great choice, top with bananas, which are full of vitamin B6 that helps with brain development and function.

Dopamine Diet Sandwich

The Dopamine Diet, popularised by celebrity chef Tom Kerridge, focuses on stress-busting ingredients to put a smile on your face.

Whole wheat bread is rich in tryptophan, an amino acid that converts to serotonin in the brain.*

Fill with tuna, as its high omega 3 content also helps to trigger the production of serotonin.

Paleo diet

The Paleo, or ‘caveman’ diet, consists of a high protein, low carb mix, mimicking the natural diet our ancestors had. If you can’t hunt or gather it, you can’t eat it. That means no pasta, cereal or bread.

You’ll have to be creative with this one, swap bread for sweet potato buns:

Method:

  • Choose a large sweet potato
  • Cut into rounds for your ‘bread’ slices
  • Roast in the oven for 25 mins

Fill with scrambled egg, spinach and bacon for a protein-packed lunch.

Gluten – free

Gluten is a protein found in wheat, barley and rye, going gluten free is recommended for treatment of coeliac disease. There are now many gluten-free breads on the market, but for a more interesting alternative, try using grilled portobello mushrooms as your slices. Fill with melted cheese and chicken for a hunger-busting lunch.

Raw food

The raw food diet is based on the principle that heating food destroys the essential nutrients and enzymes that aid digestion. Anything processed can’t be eaten, so bread is most definitely out.

Make your own wraps using rice paper rolls, fill with lettuce, avocado and red cabbage for a colourful and super healthy raw food wrap.

What about spreads?

While the obvious choice would be to opt for one of the many popular low-fat spreads on the market, they may not be as healthy as you first thought.

Although low-fat alternatives to butter can help to lower cholesterol, studies have shown that using butter is no worse when it comes to combating heart disease and strokes.**

Carly Yue, personal trainer and nutritionist at DW Fitness Clubs says: “We ultimately use spreads to add moisture – so why not try homemade guacamole, hummus or Greek yoghurt instead? All much healthier options.”
