As the winter months continue on and racing season quickly approaches, getting back on track with our diet after the holidays is at the top of most athletes minds.  While training hours are picking up it’s important we make sure we’re getting the right foods in to support our workouts and immune system health.  Here are some tips and tricks to get those nutrients and stay strong and healthy during cold and flu season!

Get a variety of fruits and vegetables:  during the colder months it can often feel more challenging to get in those recommended 6-10 servings a day. But with a little planning ahead, you can grab these nutrient rich cold weather seasonal options:

  • Brussel sprouts
  • Cabbage
  • Winter squash
  • Beets
  • Onions
  • Carrots
  • Turnips, Rutabaga, Parsnips
  • Potatoes
  • Citrus fruit
  • Pomegranates
  • Dark leafy greens
  • Escarole
  • Fennel

Frozen fruits and vegetables are also a great option as they are frozen at their peak ripeness when they are most nutrient packed. They can make a quick and easy side to meal, addition to Greek yogurt or oatmeal, or added to smoothies. 

Make sure you’re getting enough protein: as athletes, protein is always an important nutrient to promote muscle repair and recovery after workouts but it also plays a role in supporting the body’s immune system. Eat a variety of protein sources including eggs, lean meat, beans and peas, seafood, nuts and seeds. 

Key nutrients to focus on: eating a balanced diet is always the best way to promote a healthy immune system and adequate recovery between sessions but these specific nutrients can help give an extra boost:

  • Vitamin A: found in red bell peppers, kale, spinach, carrots, eggs, and sweet potatoes.
  • Vitamin C:  found in citrus fruit, red bell peppers, and berries.
  • Vitamin E:  found in nut butters, almonds, and hazelnuts.
  • Zinc: found in nuts, beans, seeds, lean meats, seafood, and milk.
