The food you consume affects how you feel and how well your body functions. While a nutrient-dense, well-rounded meal supports your immune system, a meal that’s low in nutrients and high in ultra-processed foods weakens and impairs immune function at old age. According to WebMD, the common foods that can weaken your immune system at old age are given below.
1. Many processed foods contain unhealthy fats, sugars, and additives. These can improve a product’s taste, texture, and shelf life, but as they may weaken the immune system.
2. Packaged chips, bakery items, and frozen dinners are full of salt. Too much salt in the body can trigger inflammation and increase the risk of autoimmune diseases. Salt can inhibit the normal functioning of the immune system, suppress anti-inflammatory responses and alter the gut bacteria. Thus, it’s best to limit your salt consumption in your daily diet.
3. Fried foods compete with fast foods and processed meats for AGE content. Remember, these end products increase the risk of cell damage and inflammation. They also drain your body of antioxidant mechanisms, disrupt gut bacteria and cause cell dysfunction.
4. Nicotine from cigarettes, chewing tobacco, or any other source can weaken your body’s ability to fight germs. Yes, vaping counts too. And it’s not just the nicotine. Other chemicals in e-liquids seem to suppress your immune response, especially when you inhale them through vaping.
5. Under this category, we have white bread, pasta, crackers, and cereals. Many of these are found in the packaged goods aisles at the grocery store. These also include some of those sweets we talked about earlier. These foods are made with white flour, which has been stripped of many nutrients, including fiber. Because they lack fiber, they raise blood sugar quickly and promote inflammation.
7. Drinks like soda, juices, sweetened tea, energy drinks, and alcohol have been linked to having a negative impact on human health. These can increase the production of the stress hormone cortisol, upset blood sugar levels, and interfere with the function of insulin, which can all cause a weak immune system. In addition, such drinks are known to disrupt the circadian rhythm.
