Nutrients affecting Digestive Health
We need a healthy digestive system to assimilate the food we eat; but little do we know that these nutrients are also needed to keep the digestive system healthy. From A to D, essential vitamins play key roles in maintaining digestive health. In most cases you can get these nutrients from the daily diet; but those with certain gastrointestinal diseases may need supplements, however always consult a doctor first. Read on to learn which vitamins are the most important for healthy digestion and how to incorporate them into your eating habits.
B Vitamins
These vitamins are found in proteins such as fish, poultry, meat, and dairy products, whole grain cereals, pulses, fruits like bananas, green vegetables and eggs. B vitamins are water-soluble, thus you cannot store them to use later; they need to be a regular part of your diet.
Essential B vitamins for the digestive system include:
- B1: helps the body change the carbohydrates in diet into energy.
- B3: is important for many digestive tract functions, including the breakdown of carbohydrates, fats, and alcohol.
- B6: is very important in helping digestive system process the protein in the diet.
- Biotin:This B vitamin helps the digestive system produce cholesterol and process proteins, carbohydrates, and fatty acids.
- B12: plays a role in the nervous system, the production of blood cells, and the body's use of folic acid and carbohydrates.
Vitamin C
Because it is an antioxidant, many people associate vitamin C with the immune system and preventing colds, but it also aids in digestion by supporting healthy teeth and gums and helping the body absorb iron. Food sources include: Citrus fruits (oranges, lemon, mausmi), berries (e.g. amla), tomatoes, peppers, broccoli.
Vitamin D
Vitamin D helps the body in absorbing calcium and plays a key role in how the nerves, muscles, and immune system function. Also healthy levels of vitamin D are associated with a reduced risk for colon cancer. There are three ways you can get vitamin D: Sun exposure, Vitamin D-rich foods, such as egg yolks, saltwater fish, liver, and fortified milk and cereal and supplements.
If you are not getting enough vitamin D from sunlight and food, talk to your doctor about a supplement. Keep in mind that you may already be taking a supplement that contains vitamin D. e.g. many calcium supplements also contain vitamin D.
Vitamin A
Vitamin A is involved primarily in boosting vision, bone, and reproductive health, as well as helping the immune system. Sources of vitamin A include liver, whole milk and its products, cod liver oil, kidney, egg, fish, meat and some fortified food products; colourful fruits and vegetables (yellow, orange and dark green leafy ones like carrot, papaya, tomato, capsicum, mango, apricot, spinach, fenugreek, etc. Although vitamin A is not directly involved in digestion, some gastrointestinal diseases can leave you vulnerable to a vitamin A deficiency.
So follow the mantra: Eat healthy to keep your digestive system healthy.
