First lady Melania Trump and son Barron have recovered from Covid-19, after, she says, taking “a more natural route” of vitamins and healthy eating , according to an official White House statement. She also said she kept her morale up by focusing on her family, and stressed that mental health is a crucial part of overall well-being. While her husband, President Donald Trump, took a catalogue of pharmaceuticals – including remdesivir, the steroid dexamethasone and Regeneron, an experimental antibody drug – the first lady credited her diet and “fresh air” for helping her to recover. She didn’t specify what vitamins or foods in particular she relied on, but noted that her symptoms were minimal, including aches, a cough and fatigue. “I encourage everyone to continue to live the healthiest life they can. A balanced diet, fresh air and vitamins really are vital to keep our bodies healthy,” she wrote in the statement, published Wednesday afternoon. Barron was asymptomatic The 14-year-old Barron Trump tested positive for Covid-19 soon after his parents did, according to the statement. “Naturally my mind went immediately to our son,” the first lady wrote of her reaction to she and her husband testing positive. “To our great relief he tested negative, but again, as so many parents have thought over the past several months, I couldn’t help but think ‘what about tomorrow or the next day?’” 5 things to know about sneakerhead addict Barron Trump “My fear came true when he was tested again and it came up positive. Luckily he is a strong teenager and exhibited no symptoms.” The first lady said her son has since tested negative for the virus. “In one way I was glad the three of us went through this at the same time so we could take care of one another and spend time together,” she wrote. Eating well won’t cure or prevent Covid-19 It’s true that good nutrition is essential for a strong immune system and overall health. Eating healthily can protect against some underlying conditions, such as Type-2 diabetes, obesity, heart disease and high blood pressure, that are linked to higher risks of Covid-19. However, there’s no evidence that diet alone can stave off the illness or help treat it if you do get sick. “If you’re in contact with coronavirus, it doesn’t matter how many oranges you eat, you’re going to get it,” Dr Caroline Apovian, director of the Center for Nutrition and Weight Management at Boston Medical Center, previously told Business Insider . “The only thing that a healthy diet and being in shape will do is make sure if and when you get sick, it won’t be as severe.” Vitamin D may help and Dr Anthony Fauci recommends it While the first lady didn’t mention vitamin D specifically, it’s become one of the most well-studied supplements for fending off viral infection. Her husband has also been taking a regimen of vitamins and supplements, and vitamin D is at the top of that list. Why everyone is Googling holidays in Taiwan at the end of 2020 Extensive evidence has linked vitamin D deficiency to a greater risk of infection, particularly from respiratory diseases like Covid-19, although researchers don’t fully understand if vitamin D supplements can cause better health outcomes. Dr Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, recommends taking vitamin D at the moment, and has said he does so himself. Vitamin C and zinc may shorten some infections and speed healing Two other nutrients have an important role in immune system health, but haven’t specifically been shown to treat or prevent coronavirus. Vitamin C is a well-documented antioxidant, and getting enough of it is crucial for a healthy immune system. It hasn’t been shown to prevent disease, but there’s some evidence it may make it easier for people to recover from illnesses such as the common cold. There’s also some data that zinc, a mineral necessary for human health, may help shorten the duration of some infections such as the common cold. Research has shown it’s important for immune system health generally. But so far, there’s no specific studies showing that zinc can treat or improve outcomes in patients with Covid-19. Walking and jogging outside is crucial for health and well-being As for the fresh air the first lady mentioned, taking a walk or a jog outdoors offers substantial health benefits. Exercising outdoors is one of the safest ways to work out right now, since it gives you plenty of space to avoid other people, although it’s still best to bring a mask for those times when you might encounter others. 5 ways Barron Trump isn’t like any White House resident before Doing so can boost your mood, improve your sleep, and get you some additional vitamin D (produced naturally in response to sunlight).
