Eating too much sugar
Those sugary pumpkin lattes and Halloween cookies could be wreaking havoc on your immune health.

If you want to keep your immune system working effectively, you may want to keep your alcohol consumption to a minimum.
"Excessive alcohol intake of over 14 drinks per week can suppress your immune system and can lead to more severe symptoms when you do get sick," explains DeSoto.
Eating processed snack foods
While processed snacks, like chips and cookies, may be convenient, they could be doing a number on your immune health.
"Highly processed foods contain high amounts of sodium, saturated fat (potentially even trans fat), and sugar. These components can lead to developing heart disease and kidney disease, leading to chronic inflammation and compromising your immune system," says Leonila Campos, MBA, RD, CEO and founder of Fueled by Leo, Inc.
Eating fast food
If you want to keep your immune system working effectively, you may want to think twice before hitting the drive-thru.
"Fast foods are high in saturated fats and low in unsaturated fat. High saturated fat intake can prompt inflammation in the body, thus weakening immune function," explains registered dietitian nutritionist Hannah Byrne, MS, RDN.
Eating too much salt
Before you pick up that salt shaker, consider the risk that extra sodium could be posing for your immune health.
"Excessive sodium intake causes high blood pressure and fluid retention," says Byrne. "Fluid retention causes the kidney to then excrete excess sodium, which then can reduce the body's ability to fight infection."
Not eating enough calories
While eating the wrong foods can have serious consequences for your immune health, eating an insufficient number of calories can have the same effect.
"People who purposely restrict their food intake or suffer from disordered eating behaviors or an eating disorder are more susceptible to harming their immune system," says Roxana Ehsani, MS, RD, CSSD, LDN, a national media spokesperson for the Academy of Nutrition and Dietetics. "When we don't nourish our bodies with enough nutrients each day, we aren't supporting a healthy and strong immune system."
