Sodium in Coffee & Tea

Article by Diet Bites

Salt Content Found in Coffee

Coffee is just one beverage that can be processed a myriad of ways and the nutritional values will be impacted depending upon which process is used.

Almost all the methods used for processing coffee end up with a brew that is greatly lacking in numerous vitamins and minerals. Zero Vitamin C, no thiamin or riboflavin. Generally there will be niacin to be found.

And on that note, did you know that at one time many of those in the field of medicine discouraged consumers from buying bread that contained niacin? They were confusing the word niacin with nicotine - when may seem a bit wacky, but keep in mind that the scientific name for niacin is Nicotinamide which sounds a bit like nicotine.

It is also known as Vitamin B3.

Coffee does contain scant amounts of calcium, iron, phosphorus, potassium, zinc - and yes, salt. One cup of coffee that has been brewed using purified water contains about 5 milligrams of sodium - and if it is of decaffeinated form, that doesn't mean that it is free of caffeine. One cup will still hold about 2 mg's. Instant coffee contains far more as does a regular brew. One cup of instant contains 47 mg's of caffeine while one cup of regular contains almost double that amount at 95 mg's along with 5 mg's of sodium.

Let's look closer at the nutrition facts for coffee before we address tea below.

Tea & Other Foods Containing Tannin

Many teas contain tannin which can produce a bitter taste to the tongue. If you've ever over-steeped your tea then you're probably very familiar with that extremely bitter flavor.

Other foods that also contain amounts of tannin include coffee, pomegranates, persimmons, cranberries, strawberries, blueberries, acorns, peanuts, hazelnuts, walnuts, pecans, almonds, areca nut, cloves, tarragon, cumin, thyme (and numerous other herbs), vanilla, cinnamon, legumes such as chickpeas, chocolate liquor and also woods that are commonly used to smoke fish and other foods - such as cherry wood, mesquite and oak.

The health effect surrounding tannins is still being studied by the science world so at this time. A significant intake of tannin can result in irritation of the following areas of the human body: digestive system, kidneys, trachea and stomach. It can potentially damage the liver.

Tannins can interfere with the absorption of iron absorption. Foods containing Vitamin C can assist in neutralizing the impact as well as consuming tea (as well as coffee) in between meals rather than alongside of them. The amount of tannin contained in tea depends greatly upon the leaves used for brewing. The black leaves generally contain more than green leaves.

Salt Content Found in Tea

Black tea brewed with tap water contains about 7 mg's of sodium per one cup serving. One Tablespoon of instant tea powder contains about 1 mg of sodium while herbal teas contain about 2 mg's per cup.
