Getting the flu sucks. Yet, when winter comes around, it\u2019s just something we have to deal with, time and time again, right? Wrong! Linia Patel<\/strong>\u00a0shares five effective ways to boost your immune system, so you can fend off colds and flu.<\/h3>\n

1. Stay on top of your vitamin D levels. <\/b><\/span>Super-nutrient vitamin D not only strengthens your bone and dampens inflammation but also slays colds. Recent research has shown that people with low vitamin D levels are 36% more likely to catch a cold than those who are not.\u00a0The reason for this is that vitamin D helps your body produce a protein called cathelicidin that fights bacteria. As it\u2019s the sunshine vitamin and most of us don\u2019t get enough of that over winter, it\u2019s recommended to take a supplement over the winter period.<\/p>\n

Practical tip:<\/b> In my clinical experience, 1000IU of D3 a day during autumn and winter is sufficient to maintain good vitamin D levels.<\/p>\n

\u00a02.\u00a0<\/b><\/span>Strengthen your gut:<\/b><\/span> The microbes in your gut not only help your body to digest food, but they also help to regulate your metabolism and your immune system. In fact, almost 70% of your immune system is in the gut. Eating fermented food (think bio-live yogurt, miso, kimchi, kefir, sauerkraut), popping a probiotic or increasing dosage if you are already on one boosts the level of good bacteria in your gut. The good bacteria in probiotics influence your body\u2019s T cells, the crucial white blood cells that help power your immune system. They also help reduce inflammation, which prevents infection.<\/p>\n

Practical tip:<\/b> <\/span>When you start feeling run down, reach out for an extra boost of probiotic-rich food like bio-live yogurt, miso soup, kimchi, pickles or sourdough bread.<\/p>\n

3. Eat an anti-inflammatory diet: <\/b><\/span>Studies have shown that a high intake of simple sugars decreased white blood cell production by up to 50%. Eating a diet based on whole foods and loading up on antioxidant-rich vegetables and fruit will boost your overall health and help protect you from other viruses and infections.\u00a0On the other hand, a diet that is high in refined foods and sugars will dramatically decrease your immune function.<\/p>\n

Practical tip:<\/b> <\/span>Feed your body nutrients, not empty calories \u2013 and this is especially true when you are about to get the flu or are already sick.<\/p>\n

4. Sleep some more:<\/b><\/span> Getting enough sleep is crucial for a cold-free winter and also vital for a speedy recovery if you have one. A lack of sleep leads to an increase in the body\u2019s level of cortisol, a stress hormone that can take a toll on your immune system. Lowering your levels of cortisol increases your immune response.<\/p>\n

Practical tip: <\/b><\/span>Don\u2019t sacrifice sleep, even for exercise. Aim for at least seven hours a night and, if you don\u2019t get that, then try to have a nap.<\/p>\n

5. Reach for zinc and vitamin C when you start feeling run down:<\/b><\/span> While vitamin C should be part of your\u00a0winter\u00a0regimen (think citrus fruit and fresh veg and fruit) the other nutrient that can help curb cold symptoms fast is zinc.\u00a0Research has shown that zinc (found in fish, poultry, legumes, nuts and seeds) can also help shorten the duration of a cold by a few days. That\u2019s because it has powerful immune-boosting and protective effects and studies suggest that it helps stop the replication of a cold\u2019s cell.<\/p>\n

Practical tip: <\/b><\/span>Reach for 15-25mg of zinc a day when you start feeling run down for a short-term bout (one to two weeks max). Remember that with nutrition and particularly supplements, more is not better. Long-term use of zinc can lead to a copper imbalance. Interestingly, food sources that are high in zinc are naturally balanced in zinc and copper. How cool is nature?<\/p>\n
