Limonoids best help to fight cancers of the mouth, skin, lungs, breasts, stomach, and colon. What makes limonoids so great and natural anti-carcinogens is that the body can readily absorb and utilize them for long periods of time.
Anti-carcinogen phenols in green tea and chocolate remain active in the body just for four to six hours after consumption but the limonoids in grapefruit remain active for a whopping 24 hours after consumption.

Although grapefruit is low in calories and packed with vitamins and minerals, the consumption of grapefruit can be deadly when mixed with medications. Be careful and find out more about this unfortunate combination here. Try out a few recipes!
Keep in mind that oranges do have a bit more vitamin C to spare but no reason to completely shun its fellow citrus fruits. You must be logged in to post a comment.

However, grapefruits do contain a much higher level of vitamin A. Both fruits contain a similar amount of vitamin B5 and completely lack vitamin D, vitamin K, vitamin B12 and vitamin B9 folic acid. Oranges are higher in most minerals as well. They contain higher concentrations of iron, calcium and potassium. Grapefruits, on the other hand, are richer in phosphorus.
Several epidemiological studies demonstrate a relationship between the intake of flavonoid-rich foods and the reduction of cardiovascular risk factors and mortality. Flavonoids can lower the risk of cardiovascular diseases , such as myocardial infarction, dyslipidemia and coronary artery pathology. The potential explanation may have to do with intracellular pathways involved in direct cardiovascular and cardiometabolic effects mediated by naringenin, hesperetin and eriodictyol or their glycosylated derivatives, though the mechanisms of action overall remain unclear 3.
However one study concluded that orange and grapefruit juice, though rich in polyphenols, do not demonstrate the ability to inhibit platelet aggregation, as opposed to the juice of another fruit rich in polyphenols; grape juice 4.
Platelet aggregation plays a large role in atherosclerotic disease development, increasing the risk of cardiovascular related mortality and morbidity cases. Another compound that both fruits are naturally rich in is vitamin C. A significant association has been found between high vitamin C intake and protection against cardiovascular mortality , as well as an inverse relationship with markers of inflammation 5. Diet supplemented with fresh red grapefruit positively influences serum lipid levels of all fractions, especially triglycerides, along with supporting plasma antioxidant activity.
The addition of fresh red grapefruit to generally accepted diets could be beneficial for hyperlipidemic, especially hypertriglyceridemic, patients suffering from coronary atherosclerosis. Additionally, fresh red grapefruit contains higher quantities of bioactive compounds and has significantly higher antioxidant potential than blond grapefruit 6. Orange juice intake with a high fat, high carbohydrate meal prevented meal-induced oxidative and inflammatory stress, including the increase in endotoxin and toll-like receptor TLR expression.
This may help explain the mechanisms underlying postprandial oxidative stress and inflammation, pathogenesis of insulin resistance, and atherosclerosis 7 and what role orange juice can play in it.
The consumption of citrus fruits may also protect against cerebrovascular diseases , such as ischemic stroke and intracerebral hemorrhage 8. Oranges and grapefruits both classify as low glycemic index foods. Grapefruits particularly have a low glycemic index of Including fruit, especially high in fiber and water, in diets can also play a significant role for people with metabolic syndrome, trying to manage weight gain. One study demonstrated a significantly greater weight loss in the group consuming grapefruit, grapefruit capsule, and grapefruit juice compared with groups taking placebo.
There was also a significant reduction in 2-hour post-glucose insulin level in the grapefruit group compared with placebo. Half of a fresh grapefruit eaten before meals was associated with significant weight loss. In metabolic syndrome patients the effect was also seen with grapefruit products.
Insulin resistance was improved with fresh grapefruit. Although the mechanism of this weight loss is unknown it would appear reasonable to include grapefruit in a weight reduction diet 9. One study suggests that grapefruit juice and orange juice play a good role in controlling the glucose levels of experimental animals and can be applied clinically on patients with diabetes and can lower cholesterol level.
Diabetic animals treated with orange and grapefruit had a reduced blood glucose concentration when compared to the diabetic control animals. The main compound found in citrus fruits responsible for this effect is said to be naringenin , as well as vitamin C, that has been reported to produce hypoglycemic and hypocholesterolemic effects due to their strong antioxidant properties. All antioxidants may produce a synergistic effect which may provide strengthening to the B-cells of pancreas to release more insulin Both naringenin and vitamin C have been studied for their antidiabetic, antihyperglycemic and antioxidant effects in streptozotocin induced diabetes mellitus in rats Add Grapefruit to calories calculator.
