Vitamin C helps:
- protect your body against cell and tissue damage,
- your body absorb iron better,
- your body produce collagen – the protein which holds your skin, bones and body together, and
- support brain health by producing serotonin, a hormone that affects our sleep cycle, moods, and experiences of stress and pain.

One medium-sized banana provides approximately 13% of your daily manganese needs. Manganese helps your body make collagen and protects your skin and other cells against free radical damage.
4. Potassium in bananas is good for your heart health and blood pressure
A medium-sized banana will provide around 320-400 mg of potassium, which meets about 10% of your daily potassium needs.
Potassium helps your body maintain a healthy heart and blood pressure. In addition, bananas are low in sodium. The low sodium and high potassium combination helps to control high blood pressure.
5. Bananas can aid digestion and help beat gastrointestinal issues
A medium banana will provide about 10-12% of your daily fibre needs. Singapore’s Health Promotion Board recommends a daily dietary fibre intake of 20g for women and 26g for men.
Soluble and insoluble fibres play an important role in your health. Soluble fibre helps your body control your blood sugar level and get rid of fatty substances such as cholesterol. Insoluble fibre adds weight and softness to stools, making it easier for you to have regular bowel movements. This helps to keep your gut healthy and safe from harmful bacteria.

- constipation,
- stomach ulcers, and
- heartburn
