This tongue-in-cheek article is on the very serious subject of Immunonutrition. A little- used word in the general public, it is an international concept used by millions of medical professionals for at least the past 8 years. We at “The MD, PhD is In” would like to see that you know about it.

Just for about 3 minutes, let’s pretend it’s the dead heat of summer and you just went to a swimming pool party and saw a huge carved watermelon.
On ice.

Is it just ‘water’ in a huge ball?


Hey! Let's Eat Watermelon!

1. Immunonutrition. 
Immune System (fights cancer and infections)   +   Good Nutrition (anti-oxidant, anti-inflammatory

2. Botanics. Watermelon is from the botanical family,  Cucurbitaceae: includes cantalope & honeydew.

3. “Nutrient dense.” It has a higher amount of minerals, vitamins, & anti-oxidants in great “trade” for the low calories

4. Hydrates. Watermelon is 92% water, so make sure that Mamacita abierta (Grandma) gets some, too, in that hot sun!

5. Live longer. It decreases obesity & death rate: as natural diuretic (i.e., you pee more than you drink ~ without losing potassium)

6. Low calorie. Watermelon is free of fat & cholesterol.

7. Potassium-Rich.  It’s good for your blood pressure & can prevent kidney stones.

8. Vitamin CB-carotene Rich. These anti-oxidants can decrease heart disease (#1 killer in the USA), cancer, chronic metabolic syndrome and diabetes.

9. Lycopene- Rich. Watermelon can decrease the risk of these cancers: breast, colon, lung, prostate, & endometrial.

10. Improve nerve conduction. Enhances impulses to optimize memory, learning, sleep, and muscle movement.

11. It absorbs fat.

12. It has the amino acid L-citrulline. Can decrease muscle soreness and recovery time in athletes.

13. Skin care. Watermelon makes your skin & hair healthier “From the INSIDE Out!”

14. High in Vitamin C.  It builds & maintains the matrix of the skin and hair through collagen production.

…So EAT WATERMELON to decrease FINE LINES & WRINKLES from the INSIDE out! 

15. High in Vitamin A.  Watermelon improves hair and skin, aids sebum production, prevents macular degeneration and blindness.

Hey! Let's Eat Watermelon!

Image 2. Vitamin A Function, Sources, and Deficiency. Watermelons are not the only good source of Vitamin A. Other good sources are: carrots, kale, sweet potatoes, squash, dried apricots, spinach, chard, mango, cantalope, and more.

Vitamin A deficiency is the #1 cause of childhood blindness. Liver damage can occur if too much Vitamin A is taken, so eat Vitamin A -rich foods, not supplements. Most would say to buy to grow your own from non-pesticide noncommercial seeds or buy organic only, avoiding pesticides.

Because watermelon contributes so much to so many good things about your mind & body, next time you see it, try to say:

“Please Pass the Watermelon!”
