Watermelon is considered a mildly acidic fruit (pH around 5.2-5.6) but has properties that help promote alkaline effects in the body due to its high water content and mineral profile, making it a good choice for people managing acid reflux or aiming for a more alkaline diet. While technically acidic by pH, its overall impact is often described as beneficial for balancing body pH because it helps neutralize stomach acid.
Melons are alkaline, and high in water content, which helps neutralize and dilute the acid in your stomach. Cantaloupe and honeydew are the least acidic melons. Watermelon is another great option that is also very high in water. Avocados are also low acid fruits.
Top Alkaline Foods
Watermelon is a nutrient-dense fruit with many beneficial compounds for health. Regular consumption during pregnancy can help reduce the risk of developing preeclampsia, constipation, or hemorrhoids. Its high water content can also help reduce the risk of poor fetal development, premature birth, and birth defects.
What we know is that the pH scale ranges from 0-14 with anything less than 7 considered acidic and 7 and above alkaline. Watermelon (seedless or not is unknown) has a pH range of 5.18-5.60 and is a lower acidic fruit than other options.
Eating too much watermelon may cause bloating, stomach pain, or diarrhea due to its high amount of hard-to-digest sugar. People with IBS, IBD, kidney disease, diabetes, or fructose intolerance should be cautious with watermelon intake.
Top Low Acid Fruits
The best time to eat watermelon for hydration, digestion, or weight loss is almost any time of day. The high water content, fiber, antioxidants, and vitamins in watermelon make it a good addition to meals or as a snack for supporting overall health.
Watermelon offers cooling and hydrating effects due to its high water content and nutrient profile, making it beneficial for temperature regulation, organ function, and contributing to a well-balanced diet.
Researchers often refer to the umeboshi as 'the king of alkaline foods' for its alkalizing and invigorating qualities. The organic acids of umeboshi help remove lactic and pyruvic acid from our blood that accumulate from taking refined sugar, refined grain, overly processed foods, alcohol, and red meat.
You need to have five–to–eight servings of fruits and vegetables daily, especially leafy greens and low-sugar fruits such as berries, avocados, and citrus fruits. Interestingly, even though lemons, limes, and tomatoes are all high-acid fruits, they actually help to make your body more alkaline.
Avocado is a delicious and versatile fruit and an excellent choice for pH balance. It contains healthy monounsaturated fats, fiber, and essential nutrients. Add sliced avocado to salads, use it as a spread on whole-grain toast, or incorporate it into smoothies for a creamy texture.
Urine tests measure the level of acid in the body. Optimal pH levels are between 6.5 and 7.5. When the pH level is lower than 6.5, the body is considered acidic; when the pH level is higher than 7.5, the body is considered alkaline.
Watermelon helps the liver process ammonia (waste from protein digestion) which eases strain on the kidneys while getting rid of excess fluids. Rich in potassium, watermelon is a great natural electrolyte and helps regulate the action of nerves and muscles in the body.
Remedy Your Acidity with Alkaline Foods
These foods include: Most vegetables (green or otherwise), including spinach, fenugreek, okra, cucumber, beetroot, carrot, broccoli, cabbage, coriander, cauliflower, sweet potato, eggplant, onion, peas, pumpkin and radish.
The "two-finger rule" for picking a ripe watermelon involves checking the dark green stripes on the rind: hold two fingers (index and middle) together lengthwise and place them on a dark green stripe; if the stripe is about the width of your two fingers, it's a good sign of ripeness, indicating the melon had enough time to mature, but also check for a large yellow "field spot" and a dull (not shiny) rind for best results.
Taste: Even if the exterior looks okay, there's a chance that the fruit could have gone bad. If you bit into a piece of watermelon that looked and smelled fine but its tastes sour or has a fizzy sensation on your tongue, throw it out. Feel: A slimy or slippery feel is another indication that something is amiss.
Acidic Fruits: Avoid combining melons with highly acidic fruits like oranges, lemons, or grapefruits, as this may cause digestive upset or acid reflux in some individuals. Carbonated Drinks: Carbonated beverages can cause bloating and discomfort when combined with melons due to the gas they produce in the stomach.
Certain nutrients, such as vitamins A, C, and E, folic acid tablets, omega-3 fatty acids, and antioxidants, are particularly beneficial for promoting healthy skin development and fair complexion for the baby during pregnancy.
Juices that are fresh-squeezed and sold by the glass, such as at farmer's markets, at roadside stands, or in some juice bars, may not be pasteurized, or otherwise treated to ensure their safety. Warning labels are not required on these products. Pregnant women and young children should avoid these juices.
10 Foods That Support a Healthy Pregnancy
While there's no single "number one," blueberries are widely considered top contenders for the healthiest fruit due to their high antioxidants (anthocyanins) that boost brain, heart health, and reduce inflammation, with other berries, avocados, and oranges also ranking high for vitamins and healthy fats. The best approach is a varied intake of fruits, with berries, citrus, and nutrient-dense options like avocado providing broad benefits.
