What About Watermelon Juice

While watermelon juice made fresh at home isnt taboo, do keep in mind the amount of fruit thats going into a serving. You may be better off eating a small serving of the whole fruit instead of strained juice, which has less fiber and will deliver more calories and sugar without your realizing it. Fruit juices are naturally high in sugar. About 8 oz of natural fruit juice with no added sugar could contain as much sugar as 8 oz of some sodas!10

The American Diabetes Association cautions against drinking highly sugared concentrated fruit juices or fruit flavored drinks. So be sure that you have your juice fresh if you must and perhaps combine it with fiber-rich fruits or vegetables that are low in carbs and sugar.11

Potential Risks Of Eating Grapefruit

Okay, so it’s pretty obvious that eating grapefruit on the reg is hugely beneficial to the body. However, there’s a catch. Grapefruit can interfere with an enzyme that metabolizes a wide variety of drugs, allowing more of the drug to make its way into the bloodstream and increasing the risk of side effects and even overdose. This isn’t a niche issue a 2012 study found that 85 medications ranging from OTC antihistamines to prescription blood pressure medications could be affected by grapefruit. “Taking one tablet with a glass of grapefruit juice is like taking five tablets with water,” a pharmacologist told NPR in 2012.

This is not to make you freak out about eating grapefruit. But people who regularly eat the fruit should definitely raise it with their doctor any time they’re prescribed medication to ensure that the citrus won’t cause a potentially dangerous interaction.

Citrulline Content Helps Fitness

Continuing the topic of its high citrulline content, and how our kidneys can synthesize it into arginine, there might be athletic advantages from that, too.

Since lifting weights requires increased blood flow to the muscle, nitric oxide supplements are fairly popular with bodybuilders and some athletes. The possible side effects from them and questions of their efficacy does leave a lot of doubters.

As an alternative, it seems like L-arginine supplements would be a good option . Though some research suggests that using the precursor citrulline from watermelon actually results in higher and longer plasma levels of arginine versus taking the supplements .

Citrulline supplements have been found to enhance anaerobic performance and reduce muscle fatigue . As far as the natural citrulline in watermelon juice, theres only one study which was published in 2016 which looked at this topic .

After 2 weeks of using the juice, they did conclude that it boosted nitric oxide bioavailability, but there wasnt sufficient evidence that exercise performance was improved. That study only involved 8 men and they were described as recreationally-active which is not exactly what you would call fitness buffs or serious athletes.

More research needs to be done, but if citrulline supplements work, logically it seems that potent natural food sources should also have an effect. So not only may there be the erectile dysfunction benefit for this compound, but also athletic enhancement.

Tips For Preparing And Cooking

Tips for Preparing Grapefruit

Grapefruits should be rinsed under cool water before consuming, even though you will probably not be eating the peel, since cutting into an unwashed fruit may transfer dirt or bacteria that may reside on the skin’s surface to the edible flesh.

Grapefruits are usually eaten fresh by slicing the fruit horizontally and scooping out sections of the halves with a spoon. To separate the flesh from the membrane you can either cut it with a sharp knife, a special curved-blade grapefruit knife, or a serrated grapefruit spoon. If there are seeds, you can remove them with your spoon before you eat the grapefruit.

Grapefruits can also be eaten like oranges. You can peel them with your hands or with a knife. If choosing the latter method, starting at the top, make a vertical incision that runs downward and then back up to the top on the other side and then repeat so that there will be four sections of similar size.

Be careful to only cut through skin and not into the membrane. The skin can then be peeled back with your hands or with the knife. The membranes can be separated, as you would do to an orange eaten in this manner.

Another way to serve grapefruit is to peel and slice them.
