What is iced tea?
Iced tea is a chilled beverage made by brewing tea leaves in hot water and then cooling the brewed tea. The most common varieties are black iced tea and green iced tea. Iced tea can be enjoyed plain, sweetened with sugar or honey, or flavored with lemon, mint, peach, raspberry and other fruit flavors. It is a popular summertime drink in many cultures around the world.
Is drinking iced tea good for you?
Drinking iced tea can be very healthy as long as it is unsweetened or only lightly sweetened. Tea contains antioxidants called polyphenols that can help protect against heart disease, cancer, diabetes and other diseases. Black tea and green tea have different types of polyphenols. Black tea is rich in theaflavins and thearubigins while green tea contains more catechins. All provide health benefits.
Tea also contains caffeine, which gives an energizing effect. Black tea tends to have more caffeine than green tea. Tea has less caffeine than coffee but more than soda. An 8 ounce serving of iced tea has about 47 mg of caffeine compared to 58 mg in the same amount of cola.
The hydrating properties of the water in tea make it a good choice when you need to rehydrate on a hot day. One study found that drinking iced tea hydrated people just as well as plain water.
So unsweetened iced tea can provide antioxidants and hydration in a flavorful low calorie drink. Just be mindful of caffeine intake if you are sensitive.
Are there any downsides to drinking iced tea?
There are a few potential downsides to be aware of:
– Added sugars – While plain iced tea is sugar-free, many commercial bottled teas contain added sugar or high fructose corn syrup. These added sugars bring extra calories and no nutritional benefit. The American Heart Association recommends limiting added sugar to no more than 100 calories per day for women and 150 for men. Just one 12 ounce bottle of store bought sweet tea can contain up to 46 grams or more of sugar – well over this daily limit. If you buy bottled tea, check the label for added sugars. Or better yet, brew your own unsweetened tea at home.
– Acidic for teeth – Like other acidic drinks, unsweetened iced tea can wear down tooth enamel over time when consumed frequently. This can lead to cavities or discoloration. Rinsing your mouth with plain water after drinking iced tea can help neutralize the acid.
– Caffeine sensitivity – Those with caffeine sensitivity may need to moderate their intake of iced tea due to the caffeine content. Too much caffeine can cause jitteriness, headaches, trouble sleeping and other effects in sensitive individuals.
– Kidney stones – One study found a modest link between consumption of tea, including iced tea, and kidney stones in men. The oxalate content of tea may contribute to stone formation in those already prone to this condition. But more research is needed to confirm this risk.
– Interactions with medications – The caffeine in iced tea may interact with some medications including lithium, clozapine, diabetes medications and diuretics. Check with your doctor if you take medications and have concerns about drinking tea.
So while iced tea is generally healthy, there are a few precautions to be aware of regarding sugar content, dental health, caffeine sensitivity and medication interactions. Moderation is key.
How much iced tea is safe to drink per day?
There are no official guidelines for how much iced tea an adult should drink per day. A moderate intake is likely safe for most healthy people. Here are some general recommendations based on the caffeine and sugar content:
– Caffeine – Up to 400mg of caffeine per day appears safe for most healthy adults. This would equal about 8 cups of home-brewed black iced tea. People with anxiety disorders or sleep issues may want a lower limit.
– Sugar – The American Heart Association advises no more than about 25 grams of added sugar per day for women and 36 grams for men. Commercial bottled sweet tea often far exceeds this limit in just one serving.
– Hydration – Up to 8 cups (64oz) of total beverage per day from a combination of water, iced tea and other drinks may help meet fluid needs for women. Men can aim for around 12 cups (96oz). But this can vary based on physical activity level and climate.
– Teeth – Minimize acidic drinks to meal times and limit sipping throughout the day to help protect tooth enamel. Wait at least 30 minutes before brushing after consuming acidic drinks as well.
The safest bet is to brew tea at home without sugar. This gives you control over ingredients and portions. Those with medical conditions or on medications should check with a doctor about specific precautions relating to caffeine, fluids and insulin management. But for most people, enjoying several servings of unsweetened home-brewed iced tea per day can be healthy. Just listen to your body.
Does iced tea have as much caffeine as coffee?
Iced tea contains less caffeine than coffee for typical serving sizes. Here’s a comparison of the caffeine content of these popular caffeinated beverages:
– 8oz brewed coffee – 95-165mg caffeine
– 8oz brewed black tea – 47-80mg caffeine
– 8oz brewed green tea – 29-45 mg caffeine
So an average cup of coffee has about 95mg of caffeine compared to 55mg for a cup of black iced tea and 35mg for green iced tea. However, the actual amounts can vary based on factors like brewing time, tea leaf or coffee bean variety and serving size. Longer steeping makes a stronger tea with more caffeine. Tea leaves also contain more caffeine than herbal tea blends.
The caffeine content of store-bought iced teas in bottles and cans can differ quite a bit from homemade brewed tea. For example:
– 8oz Lipton Pure Leaf black iced tea – 28mg caffeine
– 8oz Nestea lemon iced tea – 26mg caffeine
– 8oz Gold Peak sweet tea – 47mg caffeine
Tea bags result in a more concentrated tea with more caffeine compared to bottles which are diluted with water. So while iced tea has caffeine, coffee almost always contains significantly more. One exception would be a strong cold brew tea which could potentially approach coffee levels.
Does iced tea cause kidney stones?
Several large studies have found a modest correlation between higher tea consumption, including iced tea, and increased risk of kidney stones in men but not women. Researchers believe the oxalate content of tea may contribute to kidney stone formation in those already prone to the condition.
Oxalate is a naturally occurring compound in many plant foods like tea leaves. It can bind with calcium to form crystals that may grow into painful kidney stones in susceptible people. While tea does contain high amounts of oxalate, the evidence is unclear whether the levels in tea are high enough to cause problems on their own.
Researchers suggest a few reasons why tea may impact men’s kidney stone risk more than women’s:
– Estrogen may help women better regulate oxalate levels.
– Women may be less prone to calcium oxalate stones than men overal.
– Men on average drink more tea than women, leading to higher overall oxalate consumption.
For those already experiencing kidney stones, doctors sometimes recommend limiting or avoiding foods high in oxalate like tea, rhubarb, beets, spinach and almonds. But for most people, moderate tea consumption is considered safe and healthy. Drinking plenty of fluids helps dilute oxalates and flush them out. If you have a history of recurrent kidney stones, talk to your doctor about dietary changes that can help reduce your risk.
Does iced tea stain your teeth?
Yes, drinking iced tea, especially unsweetened varieties, can stain your teeth over time due to the dark pigments. Tea contains tannins, which are naturally occurring compounds in many plants that give tea its color and slight bitterness. Tannins may bind to minerals on your teeth leading to both staining and erosion.
The longer you steep tea and the darker the tea variety, the more tannins it will contain. Black teas tend to have more tannins than lighter green or white teas. Herbal blends without actual tea leaves generally will not stain teeth.
Sugary varieties of iced tea may also stain and damage teeth due to bacteria feeding on the sugars. This bacteria produces acids that erode tooth enamel.
You can help minimize staining and erosion from iced tea by:
– Using a straw to prevent contact with your teeth
– Swishing with plain water after drinking tea
– Brushing before bed if you consumed tea that day
– Choosing lighter teas like white or green varietals
– Drinking iced tea in moderation as part of mealtimes rather than constant sipping
Significant staining or erosion may require professional teeth cleaning to restore your smile. But for most people, enjoying iced tea in moderation with proper oral hygiene should not pose major tooth problems. Just be diligent about regular brushing, flossing and cleanings.
Is homemade or store-bought iced tea healthier?
Homemade iced tea is often healthier than store-bought due to less sugar and control over ingredients. Here’s a comparison:
| Homemade | Store-bought |
|---|---|

The convenience of bottled tea makes it popular, especially on the go. But with a little planning, you can brew a pitcher of tea at home to last a few days. This gives you the best flavor and nutritional benefit at the lowest cost.
Some alternatives for healthy store-bought tea are:
– Unsweetened bottled tea
– Low-sugar kombucha tea drinks
– Cold-brewed tea bags to take on the go
– Sparkling unsweetened tea blends
Reading labels to check sugar content is important when purchasing any bottled tea. But enjoying tea you brew at home using fresh ingredients is a great way to reap the most benefits of this classic beverage. The variety of flavors from fruits, herbs and spices you can add makes homemade tea endlessly customizable to your tastes as well.
What is the healthiest type of iced tea?
All non-sweetened iced teas made from true tea leaves (green, black, white, oolong) have excellent health benefits. But here are some varieties particularly high in protective plant nutrients:
– **Green tea** – Rich in antioxidants called EGCG that may help prevent heart disease, Alzheimer’s disease, cancer and other conditions. Has 35-45mg caffeine per 8oz serving.
– **White tea** – Made from young tea buds and leaves. Contains the same EGCG antioxidants as green tea. Very low in caffeine at just 15-25mg per 8oz serving.
– **Hibiscus tea** – Made from the hibiscus flower. Provides antioxidants like anthocyanins that may help lower blood pressure. Naturally caffeine free.
– **Rooibos tea** – Herbal tea high in flavonoids like quercetin. May boost heart health. Naturally caffeine free.
– **Mint tea** – Fresh mint provides antioxidants like rosmarinic acid and menthol. Also helps soothe digestion. Caffeine free.
– **Ginger tea** – Fresh ginger root is anti-inflammatory and aids digestion. Good source of gingerol antioxidants. Caffeine free.
Any of these iced teas can be enjoyed straight up or flavored with fruits, herbs or a splash of juice. The healthiest preparation is to brew your own at home using filtered water, high quality tea and fresh ingredients. This avoids the extra sugars and preservatives added to most store-bought varieties.
Is it safe to drink iced tea when pregnant?
Most healthy pregnant women can safely consume moderate amounts of iced tea. Black, green and herbal teas have all been studied and appear to have minimal risks during pregnancy when consumed in normal food amounts. Here are some guidelines for drinking iced tea while pregnant:
– **Caffeine** – Limit to less than 200mg daily. Caffeine passes through the placenta to the baby. Too much may result in low birth weight. An 8oz serving of black iced tea has about 40mg caffeine.
– **Sugar** – Avoid bottled sweet teas high in added sugars which provide empty calories. Better to sweeten minimally with honey, if at all.
– **Herbal teas** – Most are safe including ginger, peppermint and hibiscus when consumed occasionally in moderation. Avoid hibiscus late in pregnancy due to potential uterine stimulation.
– **Foodborne illness** – Use freshly boiled water when brewing tea to avoid any rare toxins from bacteria. This goes for all foods and drinks during pregnancy.
– **Interactions** – The caffeine in tea may exacerbate nausea, heartburn or anxiety from pregnancy hormones in some women. Discuss your symptoms with your doctor.
Moderate intake of up to 2-3 cups of iced tea per day appears safe for most healthy pregnancies. But it’s always wise to check with your doctor about your specific health status. And be sure to choose varieties low in added sugar and high in nutrients.
Can children drink iced tea?
Children can drink moderate amounts of iced tea on occasion but there are some considerations regarding caffeine content and tooth decay. Here are some guidelines:
– **Toddlers** – Avoid tea due to potential fluoride binding effect on developing teeth. Water or milk are better choices.
– **Ages 4-7** – Limit to 4 ounces diluted with water due to caffeine.
– **Older children** – Allow no more than 8 ounces per day. Use caution with dark varieties high in tannins that can stain teeth.
– **Added sugars** – Skip presweetened bottled tea which contributes empty calories and dental decay.
– **Caffeine sensitivity** – Avoid tea in the evenings which may impair sleep. Monitor for jitteriness.
– **Hydration** – Tea can help with hydration but shouldn’t replace water as the primary beverage.
– **Teeth** – Choose lighter teas and limit acidic drinks to mealtimes. Emphasize good oral hygiene.
– **Age 10+** – Healthy children can have moderate amounts of unsweetened tea. But limit if having trouble sleeping or anxious.
Tea offers some nutritional benefits but water and milk are still the healthiest choices for hydration in childhood. Lightly sweetened or diluted iced tea in moderation is a nice occasional treat for most kids starting around age 4. Just take care to minimize sugars, acidity and caffeine. Check with your pediatrician if you have questions about serving tea.
Conclusion
For most healthy people, enjoying iced tea in moderation is safe as part of a balanced diet. The best approach is to brew your own using quality tea leaves, filtered water and added lemon, herbs or fruit to taste. Just go easy on sweeteners. The antioxidants, hydration and small amount of caffeine in an unsweetened glass of fresh iced tea make it a nutritious beverage for warm weather. Those with sensitivities to caffeine or certain medications should be mindful of tea’s caffeine content and consult a doctor. But for most, a daily glass of home-brewed iced tea is a refreshing way to stay hydrated and healthy.
