"Believe it or not, most immune support is based upon the health of the individual,” said Registered Dietitian for HelloFresh Rebecca Lewis. “If you eat an adequate healthy diet full of nutrient-dense foods, stay hydrated and exercise regularly—your ability to fight the common cold increases greatly. When you are feeling run down, it is always a good idea up your intake of fruits and vegetables to replace any critical vitamins and minerals you may be missing in your diet. It’s also important to manage your stress and get enough sleep to keep up your mental energy.”
