Health Benefits of Fruits and Vegetables
You know vegetables are good for you, but why is this true? Those who eat vegetables as part of their daily diet, can have a reduced risk of developing many chronic diseases. Nutritionists agree that making half of your plate up with vegetables, is a wise health choice.
Vegetables play an important role in healthy eating and provide a wide variety of nutrients. These include fibre, folate, antioxidants, vitamins A, E and C, and potassium. Vegetables like broccoli, spinach, tomato, garlic and onion provide additional benefits, hailing them as a superfood.
Health benefits of vegetables include:
- The potassium found in many vegetables such as green leafy vegetables may help to maintain healthy blood pressure levels;
- The fibre found in vegetables, especially when the skin is left on, helps maintain a healthy gut and digestive system. Fibre also helps to reduce blood cholesterol levels and may lower the risk of developing heart disease;
- Folate or folic acid helps to form healthy red blood cells in the body. Pregnant women or those planning on conceiving need adequate folate in order to reduce the risk of neural tube defects and spina bifida during foetal development.
What the studies suggest:
- An increased vegetable consumption may reduce your risk of high blood pressure; 
- Consuming an increased amount of vegetables protects against cancer of the stomach and pancreas as well as colorectal, prostate, and bladder cancers. Lung cancer risk may be lowered for smokers who eat their vegetables;
- Eating more vegetables including the fibre, can help you to lose weight;
- The risk for developing Alzheimer’s as well as diabetes, may be lowered with higher vegetable consumption;
- Consumption of vegetables, especially leafy green vegetables and those with vitamin C, appears to be have a protective effect against coronary heart disease.p, Vitamin C is present in vegetables such as tomatoes, capsicum, broccoli as well as green leafy vegetables.
