3 Quick Reasons To Eat Grapes

Tasty and versatile, grapes make a delicious snack and salad addition. But their pungent acidic powers offer so much more than snackability. We’re covering three quick reasons below before diving deeper into the details:

  • Resveratrol — This antioxidant appeared years ago as a supreme skincare ingredient. Eat a handful of grapes and you’ll reap the advantages linked to anti-aging and cancer prevention.
  • Low glycemic index — Scoring a 43-53 on the index, they’re a good choice for diabetics. Diabetics should avoid foods scoring above 55. They’re also a smart snack choice for those monitoring their blood sugar levels.
  • Improved cognitive function —We’ll dive deeper into this later, but grapes have been shown to protect your central nervous system. This means your brain and spinal cord. The protection comes from flavonoids that can prevent memory loss and amplify brain function.

Are Grapes Acidic Compared To Other Foods?

Grapes Acidic

As mentioned in the quick answer, almost all fruit is acidic. Grapes are no exception with a pH that ranges between 3.5 and 4.5. Check out the table below based on research from Clemson University to see how the pH of different varieties of grapes compares to other fruits. Remember, the lower the pH, the more acidic it is.

*The data shown in the table above reflects the highest recorded pH values of common foods. pH values vary among different types of each food shown above. Time and temperature can also contribute to varying pH values.

The table above indicates grapes fall somewhere in the middle between the least acidic and the most acidic fruits.

Why Does The Acidity Of Grapes Matter?

Grapes Acidic

As noted earlier, grapes contain acids that make them a vital source of antioxidants, metabolites, and nutrients. This makes grapes a powerful tool in combating viral infections such as the common cold and the flu. The acids can also prevent chronic diseases such as diabetes, and even cancer. Grapes are plentiful in

  • Vitamin B
  • Vitamin C
  • Vitamin K
  • Manganese
  • Fiber
  • Beta-carotene
  • Flavonoids
  • Resveratrol

What are the benefits of the list above? Let’s dig in with five key points from Dr. Axe’s article:

  1. Combat heart disease — Research indicates that vitamins can help you avoid heart disease. While these vitamins can’t be expected to act alone against heart attacks, they can help in the battle. Notable heart warriors include vitamins B, C, E, and K, which can decrease stiffness and hardening of your arteries.
  2. Oxidative stress prevention — Grapes are strong defenders against oxidative stress, resveratrol, and beta-carotene. They’re also full of metabolites known as flavonoids, which can do the same. Combined, these phytonutrients and metabolites are a dynamic duo fit for heart protection.
  3. Inflammation reduction — The flavonoids in grapes also act as an anti-inflammatory. This means they can help prevent chronic inflammation without the need for medication in many cases.
  4. Improved cognition — These same inflammation-reducing flavonoids can help contribute to better cognition. This means grapes can potentially help prevent brain fog, memory decline, and more.
  5. Improved cognition — These same inflammation-reducing flavonoids can help contribute to better cognition. This means grapes can pote of the low-glycemic index we mentioned early on. Grapes were also reported to have a positive effect on blood sugar levels.

The benefits of grapes cannot be understated. While we gave a high-level overview above, you don’t just have to take our word for it! There’s a reason grapes are constantly admired by scholars.

When It Comes To Grapes, Sharing Is Caring. So We’re Sharing 5 Tips.

Grapes Acidic

When it comes to purchasing and storing grapes, we suggest the following

  1. Go organic — Grapes are no stranger to the dirty dozen list, so choosing organic is more than a suggestion. This helps you avoid pesticide exposure while supporting eco-friendly farming.
  2. Look for consistency — The best grapes should be uniform in color and still on the stem. Green grapes should appear slightly yellow, while red and black grapes shouldn’t have any visible greenness.
  3. Avoid washing — Many recommend not washing grapes before storing to prolong their lifespan. Moisture can heighten their decay, which means they won’t last as long. Rinse them right before you eat them for the best results.
  4. Keep the bag — Most grapes come in bags with holes that promote airflow. This is ideal for grape storage, so don’t move them to Tupperware.
  5. Refrigerate them — Like most food, grapes stay fresher in the fridge. Although safe to consume at room temperature, they won’t last as long.
