Grapes are a great source for numerous nutrients. But this is not all important nutrients are also contained also in the grapes seeds (tannic substances, lecithin, phlobaphene and fatty oil), grape skin (tannic substances and oils) and even the grape leaves (sugar, carotene, tannic substances, potassium, sodium, silicon and iron).The health benefits of grapes can help treat constipation, indigestion, fatigue, kidney disorders, macular degeneration and prevention of cataract. Grapes are one of the most delicious fruits and are rich sources of vitamins A, C, B6 and folate in addition to essential minerals like potassium, calcium, iron, phosphorus, magnesium and selenium. Grapes contain flavonoids that are powerful antioxidants, which can reduce the damage caused by free radicals and aging. I love having grapes on the table for when my kids come home from school. Another great trick to keep those grapes all week long, do what the Guncles do…freeze them. I buy green, red and purple to make a colorful container. Rinse and take them off the stem and store.
