If you’re anything like me, and nearly every other human being on the planet, you love to have an ice cream or a smoothie every once in a while. But you might want to stop and think the next time you go to Starbucks for your iced mocha latte, because there is reason to believe that cold food and drinks are not so good for our health. Here’s why.

Our bodies are designed to process food and drinks that are warm, or at least room temperature. When you swallow that first spoonful of ice cream, you’re actually imposing serious stress onto your digestive system. Consuming cold food or drink on an empty stomach (i.e. in the morning) only compounds the problem, oftentimes leading to bloating, puffiness in the face, breakouts of acne and gastrointestinal issues, among other things.

The shock your system receives from an ice-cold beverage or food makes it harder for your body to take in any nutrients that might be present. When we don’t absorb nutrients, that creates a host of problems. It can cause disruption to our menstrual cycle and ovulation period, and worsen the symptoms of PMS. Consuming warmer food and drinks have the opposite effect, making them critical for fertility. If you’re trying to get pregnant, consuming smoothies and iced coffee will only make things harder for you.

Holistically speaking, warm food is also said to keep our hormones in proper balance. Cold food, on the other hand, is said to throw them off kilter, causing a range of problems including but not limited to stress, peevishness, thinning hair, skin irritation, too much stomach acid and changes in bowel habits.

So, try weening yourself off the smoothies and iced lattes and see if you notice any improvement in your physical and psychological wellbeing. Instead, drink warm coffee or tea, and room-temperature almond milk; eat dried fruits, vegetable soup, nuts, legumes, avocado and dark leafy greens (not out of the fridge!).
