    Yams are grown in tropical regions and have a creamy flesh and may or may not be sweet.  The flesh is drier than sweet potatoes.  They come in different colors such as purple, white, red.   They have a rough, scaly skin.  Real yams are nothing like what we in the USA call "yams."  That came about because some (imported) yams were confused with American grown white potatoes.

    Sweet potatoes have smooth, thin skin, yellow or orange flesh (one variety is purple) and are sweet and moist.


    I haven't looked into the nutritional difference, but I can find out if anyone is interested.

    Nutritional Comparison between Yams and Sweet Potatoes

    Vitamin A

    Sweet Potatoes contain more Vitamin A, than yams.

    Vitamin A is known to fight cancer, builds our immune system, and is considered critical in maintaining proper eye health.

    Sweet potatoes are loaded with massive amounts of vitamin A, a nutrient considered critical in maintaining proper eye health. In fact, one sweet potato contains nearly eight times an adult's daily need of this important vitamin, and, because vitamin A is fat-soluble rather than water-soluble, the body can store it for later use.

    Yams contain vitamin A but in significantly less amount than sweet potatoes (yam - 122 IU, sweet potato - 19217 IU).

    So, when it comes to vitamin A, sweet potatoes are better than yams.

    Calcium, Iron, Vitamin E, and Protein

    Sweet potatoes contain significantly higher amounts of calcium, iron, and vitamin E, and twice as much protein per serving, than yams.

    Sweet potatoes also contain several other vitamins and minerals in amounts not found in the yams.

    Although yams also contain calcium, iron, vitamin E, protein, several other vitamins and minerals, they are in lesser amounts per serving, than sweet potatoes.

    So, when it comes to calcium, iron, vitamin E and protein contents, sweet potatoes are better than yams.


    ------------------------------------------------ ♥♥♥ ------------------------------------------------


    Omega-3 and Omega-6 Fatty Acids

    Sweet potatoes contain less omega-3, and more omega-6 fatty acids, than yams.

    Omega-3 fatty acids have received significant news coverage in recent times owing to their ability to do everything from prevent heart disease to increase brain stamina.

    Omega-6 fatty acids are known to inhibit the body's ability to make use of the omega-3's.

    Although both the yam and the sweet potato are low-fat foods, the ratio of essential fatty acids is preferable in the yam.

    Sweet potatoes contain less omega-3 fats than yams, and have nearly twice as much omega-6 fats.

    So, when it comes to fatty acids, yams are better than sweet potatoes.


    ------------------------------------------------ ♥♥♥ ------------------------------------------------


    Anti-inflammatory Nutrients

    Anti-inflammatory compounds are very important in the health of people with irritable bowel syndrome (IBS), arthritis, gout, and other inflammation-related diseases.

    Sweet potatoes contain massive amounts of these anti-inflammatory nutrients; yams don't.

    Yams, not only lack these anti-inflammatory nutrients, but actually contain a number of compounds that aggravate inflammations.

    So, when it comes to anti-inflammatory nutrients, sweet potatoes is the big winner.


    ------------------------------------------------ ♥♥♥ ------------------------------------------------


    Potassium, Magnesium, Phosphorous and other Minerals

    Both yam and sweet potato are both loaded with potassium, magnesium, and phosphorous, as well as several so-called trace minerals: selenium, zinc, and copper.

    However, although both sweet potato and yam seem to have similar high concentrations of key minerals, sweet potatoes have just a little more.

    So, when it comes to minerals, sweet potatoes are a little bit better than yams.


    ------------------------------------------------ ♥♥♥ ------------------------------------------------


    Which is better for people with Diabetes?

    Both the sweet potato and yam offer special health benefits to people with diabetes. Both have very low glycemic indexes: sweet potato weighing in at 17, and yam weighing in at 16. However, sweet potatoes might actually help to fight against diabetes.

    Although final reports have not yet been published, preliminary researches show that long-term consumption of sweet potatoes can actually help to fight against diabetes symptoms.
