Nutrition expert reveals the must-have ingredients for meal prep ahead of the London Marathon

  • A nutrition expert reveals which ingredients appear most frequently across top-rated recipes- and names the must-haves for your London Marathon meals.
  • Using data from the nation’s top recipe site, the research analysed over 200 top-rated recipes to see which ingredients proved the most popular.
  • The top ingredient came out as garlic, followed by onion, and olive oil – with garlic being known for its anti-bacterial and flu-busting properties to keep you fit before the big run.

A nutrition expert has listed the key ingredients to have in your muscle-building meal preps ahead of the London Marathon, according to recipe reviews – and it turns out garlic is essential.

The sports nutrition experts at Bulk.com analysed over 200 protein-rich recipes rated four stars and above on the nation’s leading recipe site BBC Good Food, to identify which ingredients appeared most frequently and reveal how their health benefits can help you perform your best.

As well as looking at which ingredients are must-haves for your cupboards, the study also analysed the nutritional content of popular dishes to see which are the best for building muscle and helping with stamina – and created three staple recipes designed to help you prioritise meal prepping.

And it turns out these are the top five ingredients you need to include in your meal prep this season:

  1. Garlic – Garlic proved the most popular ingredient, as it is essential to virtually every dish analysed. Known for its antibacterial properties, garlic offers protection against the common cold – which is great news for maintaining your health ahead of the run – and is also a useful source of potassium to support normal blood pressure.
  1. Onion – The backbone to plenty of dishes and proving among the most popular ingredients in the study, onions are a source of organic sulfur compounds which work to reduce cholesterol. They are also a reliable source of B and C vitamins, which help different enzymes function and strengthen our immune system.
  1. Olive Oil – Olive oil also appeared frequently across the top-rated recipes. Not only is it a great source of healthy monosaturated fats, but olive oil has also been shown to have anti-inflammatory properties and be an excellent source of antioxidants, helping your body neutralize free radicals that cause diseases.
  1. Tomato – Tomatoes make a solid base for many meals and they make a great source of fiber. Additionally, they area good source of vitamin B9 (folate) which aids tissue growth and normal functioning, as well as vitamin K1 (phylloquinone) which is important for bone health. Like onions, they are also a great source of vitamin C.
  2. Nuts – A variety of nuts can be great for the diet as they are packed with plenty of dietary fibre, healthy fats, and magnesium – particularly almonds, cashews, and brazil nuts. This helps to regulate biochemical reactions such as blood pressure, sugar levels and muscle function.
  3. Other ingredients that frequently occurred in popular recipes include pumpkin and butternut squash. Both are high in beta-carotene which converts into vitamin A and helps to maintain a healthy immune system, as well as maintain good skin and eye health.

Some surprising ingredients also included spinach, high in iron – which many people do not get enough of – and mustard, which is a great source of omega-3 fatty acids, as well as calcium, iron, and zinc.

Fish also appeared frequently in the top-rated recipes, which can be a source of vitamin D and omega-3 fatty acids. This is particularly helpful as we have a reduced ability to make vitamin D when it is cloudy.

A spokesperson from Bulk.com commented: “It is important for athletes to get nutritionally rich meals, especially ahead of the London Marathon which requires a lot of physical, and mental, effort.

“In order to make sure you are eating healthily and prioritising your training, meal prepping is a fantastic way to save time during the week before the big event, especially when you might not feel like cooking.

“Including these ingredients in your meal prep can help boost immunity and ensure you’re getting a varied diet full of protein and vegetables that will help you keep up your stamina and perform to the best of your abilities.”

The current British Nutrition Association guidelines suggest the average person requires 0.75g per kg of body weight of protein a day, and with chicken, chickpeas and lentils occurring in the top 20 ingredients, these are key to a balanced meal for those focusing on building muscle and eating healthily before the event.
