Yellow unripe Banana vs Black spotted ripe Banana

posted in: Science & Facts | 0


Everyone loves to eat them. They have a ton of good qualities and delicious taste. Bananas contain a fair amount of fiber, as well as several antioxidants. One medium-sized banana (118 grams) also contains:

  • Potassium: 9% of the RDI.
  • Vitamin B6: 33% of the RDI.
  • Vitamin C: 11% of the RDI.
  • Magnesium: 8% of the RDI.
  • Copper: 10% of the RDI.
  • Manganese: 14% of the RDI.
  • Net carbs: 24 grams.
  • Fiber: 3.1 grams.
  • Protein: 1.3 grams.
  • Fat: 0.4 grams.

*RDI – Reference Daily Intake

Each banana contains only about 105 calories, and consists almost exclusively of water and carbs. Bananas contain very little protein and almost no fat. The carbs in unripe (green) bananas consist mostly of starch and resistant starch, but as the banana ripens, the starch turns into sugar (glucose, fructose and sucrose).

Eating bananas with black spots instead of when they are yellow-green and unripe could mean a world of difference in terms of how they benefit the body. The fact is, is that the riper the banana, the better anti-cancer qualities they possess.

Surprised!! The fact is that any fruit at its peak ripe stage contains highest concentration of vitamins, minerals and crucial cancer-fighting phyto-nutrients. Fully ripe fruit also helps in digestion. Un-ripe fruit, if you have ever noticed, causes stomach issues like heart burn, bloating, gas, indigestion etc. If you eat mostly raw vegan diet, then you have experienced what I’m talking about. Unripe fruit should not be eaten. Always eat ripe fruits, folks!!

Okay, so back to bananas. Japanese researchers have proven that ripe bananas fight cancer. The dark spots on ripe yellow bananas signal that your banana contains high levels of a substance called Tumor Necrosis Factor (TNF), which destroys cancerous tumours. If you let your bananas sit on the counter and ripen fully, they will have higher antioxidant levels, which means better immune-strengthening effects, and a higher white blood cell count. In fact, yellow-skinned bananas with dark spots were found to be 8 times more effective at enhancing the cancer-fighting properties of white blood cells than their just yellow skinned or green-skinned counterparts.

Tumor Necrosis Factor (TNF-α) and Cancer

TNF-α is a cytokine (cell-signalling protein), involved in systemic inflammation and is produced chiefly by macrophages (a type of white blood cell that digests foreign substances and dead cells). The primary role of TNF is in the regulation of immune cells, and directing cell movement toward inflammation and infection sites in the body. It helps prevent the growth and spread of tumour cells and triggers apoptosis (cell death). Studies have found that the levels of TNF-α increased significantly with dark spots on the skin, before the entire banana peel turned brown. The study conducted by Japanese researchers found that the activity of dark-spotted bananas was comparable to that of Lentinan, a chemical immuno-stimulant that is intravenously administered as an anti-cancer agent to stimulate white blood cell production. Eating ripe bananas not only improves your chance of fighting cancerous cells, but it also means better digestion, moods, stronger bones, and better blood pressure.

Yellow V/S Green Banana

Both yellow and green bananas are high in fiber, potassium, vitamin B6, and vitamin C. No matter the hue, bananas nourish your gastrointestinal track and aid in digestion. Green bananas do have the benefit of being less sugary, however. When a banana ripens, its starch content consists of mainly simple, easy-to-digest sugars that elevate blood sugar levels. Insulin resistant or diabetic individuals should monitor their intake of sugary ripe bananas. As the cancer-fighting properties of ripe bananas increase, their micronutrient profile (vitamin and mineral content) does take a dip down. The solution? Mix up your fruit bowl with both fully ripe and green-tinted bananas.
