Comments (15)While there's some evidence that grapefruit might have cancer-fighting properties, a recently published study found that grapefruit actually increased the risk of breast cancer in some women: "Women in the highest intake categoryÂ60 grams or more per day, equal to slightly more than one-quarter grapefruit per day or half a grapefruit every other dayÂhad a relative risk (RR) of breast cancer 30% higher than women who ate no grapefruit (RR = 1.30). The trend of increasing risk with increasing consumption was significant (P = 0.015) after adjusting for weight, exercise, use of postmenopausal hormone therapy, family history of breast cancer, and other factors that could impact risk. The same association was evident for women who had never used postmenopausal hormone therapy (RR = 1.44; P = 0.038) and for those with a body mass index below 25, the cutoff for overweight (RR = 1.32; P = 0.011). Although risk also increased for women who were current or past users of hormone therapy (either estrogen-only or estrogen-progestin combination therapy) and for those with a higher body mass index, the differences were not statistically significant. This finding suggests grapefruit's effect on estrogen is greatest in women whose baseline levels are lower to begin with, Monroe says. The results are consistent with a biological effect of grapefruit on estrogen metabolism. At least 2 previous studies have found higher estrogen levels in women consuming grapefruit or grapefruit juice, the authors note, and grapefruit is known to elevate serum concentrations of many drugs, including hormone replacement therapies. The US Food and Drug Administration requires hormone replacement products to carry warning labels stating that grapefruit juice may increase plasma concentrations of estrogen. More study will be needed before this possible link to breast cancer can be confirmed. We do know that grapefruit affects metabolism of a number of drugs, so checking with your doctor before adding a grapefruit seed extract product is a good idea....See MoreIndoor Grapefruit Never Blooms
Comments (19)Has anyone tried the breeder's trick with citruse from seeds? Well the trick is to graft a budwood from a seedling tree unto an old fruiting compatible citrus cultivar. This will shave off significant number of years of waiting for a citrus seedling to fruit. And yes, this trick is the other way around and has worked very well for pome and stone fruits. In order to save time to know the type of fruit a newly hybridized seed will have, instead of growing it and waiting for it to fruit, they graft it unto fruiting trees of the same type. The resulting interaction has been proven to significantly reduce the number of years of wait time for a new hybdridized seedling to bear fruit. I was wondering if this could be true for citrus. In the specific case of the grocery grapefruit, most likely it would be nucellar and so is the exact clone of the parent, so why not use the budwood from the original parent and graft unto the seedling instead? However, if the seedling is suspected to be a hybrid, for sure it will have different character and particular mix of the parents, and now that it is twenty years old, grafting buds from this tree unto a fruiting grapefruit should shorten the wait time, but the probability that it is a hybrid is not on the good side. However for those who have been hybridizing citruses and wanting to know the type of resulting fruit you have, you might do the trick of grafting the seedling unto a fruiting mature tree....See MoreApple Grapefruit Jam or Marmalade
Comments (1)The pith of grapefruit is quite bitter. You can cut away about half of teh thickness of the white part and use the yellow part in the marmalade. A blend of different citrus can also be done. Citrus, with regular pectins can take a month r longer to set. Using Pomona pectin, the results are much faster. Pomona is a citrus based pectin, so it may even set with very little added calcium. As mentioned in other recent threads, regarding Pomona, I use a blender to dissolve the Pomona powder in some of the liquid, or water. Then, its poured into the boiling mixture and will quickly dissolve. Lastly, the calcium water is added....See MoreQuestion about Thyroid and interaction with certain foods.
Comments (9)Lydia, that was really interestingÂthanks! I had no idea soy was a possible culprit. It doesn't seem to bother me, and thank heavens for that because I consume soy in many forms. My DH used to manufacture tofu commercially, and I still love itÂalong with soy milk, tempeh, edamame, etc. I learned about the thyroid-cabbage link about a year ago when I got the bright idea to make up a large batch of coleslaw with fruit and a yogurt-based dressing, and reach for that whenever I wanted to snack. I was eating a lot of coleslaw! But I thought that was fine because what could be healthier than raw cabbage? After a while I began to feel wretched....zero energy, difficulty concentrating, thoughts drifting away, hair falling out, etc. A health-savvy friend asked if I happened to be eating much cabbage. I certainly was! She explained the connection. I got back on track by taking kelp (and giving up the coleslaw)....See More- last year
