Safety Features: Porcelain mugs are made from high-quality material and do not contain lead, cadmium or BPA that may cause the release of toxic chemicals into your beverages. This makes porcelain safe and suitable for use in everyday life, especially for those who are conscious of their health and safety.
Glass and ceramic mugs are inert, won't react to heat or acidic liquids, and are among the healthiest drinkware options.
Ceramic and stainless steel is the only safe materials to drink hot liquids from.
For everyday use, ceramic and stainless steel are often considered the best options for their combination of durability, insulation, and taste neutrality. If you're looking for something more eco-friendly, bamboo composites are a good choice, while glass offers a stylish option but with more fragility.
The Healthiest Way to Serve Coffee
The healthiest way to drink your coffee is black, and if you start with a flavorful, high-quality bean, you shouldn't need to add anything. “The reason people started putting milk in coffee during the World War II is because they were drinking terrible coffee,” Arnot says.
The healthiest way to take your coffee is hot-brewed and black. One cup has virtually no calories or carbs, no fat, and is low in sodium. Black coffee also has micronutrients, including potassium, magnesium, and niacin.
If ceramics are baked for long enough at hot enough temperatures, they may still be safe, but if not, the lead can leach into food and cause lead poisoning. Acidic food or drink is especially likely to cause lead to leach out of ceramics, unfortunately for coffee drinkers with favorite earthenware mugs.
The most common materials used for coffee cups are plastic, metal, glass or ceramic. Plastic cups will retain flavors in time, which will take away from your coffee experience. Metals like stainless steel will be the most durable and do well in the way of heat retention.
Porcelain holds temperature better than regular ceramic, but it's also non-porous and easier to keep clean of coffee stains.
Mugs made of stainless steel with a double wall will retain heat for the longest time. That said, if you're sipping your coffee at home, you can get away with a stoneware or ceramic vessel, with thick walls that will keep your sip hot for a decent amount of time.
Glass is the safest water bottle type and offers the purity of taste, but stainless steel offers insulation benefits that keep your beverages hot or cold. Don't forget about a filter!
Similar to the French Press, The Pour Over is made of glass, making the method a non-toxic way to brew coffee. Using a metal filter preserves the oils in the coffee and makes it a healthy cup of joe.
Starbucks paper cups have two main components, a paper layer and a polyethylene layer. The paper layer consists of 90% virgin paper board and 10% post-consumer paper (Luna 8). Starbuck's paper cup manufacturer, International Paper, actually has a patent to have 10% post-consumer fiber in a polyethylene paper cup.
Use alternatives to plastic for food and drink storage.
The safest container materials include glass (ex. Pyrex), stainless steel, and lead-free ceramic.
Daily Caffeine Consumption for Most Adults
For most adults, the FDA has cited 400 milligrams* a day — that's about two to three 12-fluid-ounce cups of coffee — as an amount not generally associated with negative effects.
The size of your cup is important as it should match the amount of coffee you like to drink. For espresso lovers, a small cup is ideal, while those who prefer longer coffees may opt for a mug. The choice of material can influence the flavor and temperature of your coffee.
Choosing the right size.
Or is it one cup after another? If one cup is all you need, a standard coffee cup that holds 8 to 12 ounces of liquid is sufficient. If you just can't have enough of coffee, you may want to consider a larger cup that holds 24 to 36 ounces.
Always check the labels
Be sure to check the items for labels warning whether they are or aren't safe to use with food or drinks. The FDA requires that unsafe ceramic pieces have a conspicuous stick-on label or permanent statement that warns consumers about it.
Look for a warning label. If the pottery was manufactured for use only as a decorative item, it may have a warning stamped onto the clay bottom such as “Not for Food Use—May Poison Food.” Do not use items with this type of warning for cooking, serving, or storing food or drinks.
Alliance alleges that 10 Strawberry manufactured and distributed and offered for sale in the State of California mugs containing Lead, and that such sales have not included warnings pursuant to the Safe Drinking Water and Toxic Enforcement Act of 1986, California Health & Safety Code sections 25249.6 et seq.
“Cold brew coffee has less acidity due to the cold steeping process and can be a more attractive choice for those with a sensitive stomach,” she notes. Of course, if you find that caffeine, in general, causes your tummy troubles, it's also worth switching to a decaf blend.
Established studies have also shown that caffeine is good for your gut, stimulating the colon and leading to regular bowel movements. One 1990 study showed that people who drank coffee tended to need the loo 30 minutes after drinking a cup. In so many ways, the gut appears to love a cup of joe.
Caffeine may cause a brief rise in your blood pressure, even if you don't have high blood pressure. This short-term spike in blood pressure happens mainly in people who don't drink caffeine often, rather than in those who do. Still, the blood pressure response to caffeine differs from person to person.
