Q & A
What are vitamins and why are they essential for our body?
-Vitamins are organic molecules that are essential micronutrients for our body. They are crucial for metabolism and cannot be synthesized by the body, hence must be obtained through diet. They play a vital role in various bodily functions such as aiding in wound healing, improving immunity, and maintaining nervous system function.
What are the two main types of vitamins and how do they differ in terms of solubility and storage in the body?
-The two main types of vitamins are fat-soluble and water-soluble. Fat-soluble vitamins, which include vitamins A, D, E, and K, are dissolved in fats and can be stored in the liver and adipose tissue. Water-soluble vitamins, such as the B vitamins and vitamin C, dissolve in water, are not stored in the body, and require regular intake.
What is the primary function of vitamin C in the body?
-Vitamin C is central to iron absorption and collagen synthesis. It aids in wound healing, bone formation, and improves the immune function. A deficiency in vitamin C can lead to scurvy.
Which foods are known to be rich sources of vitamin C?
-Citrus fruits are the main sources of vitamin C, but it is also found in vegetables like peppers, broccoli, and cabbage, as well as in fruits like guava, papaya, watermelon, kiwi, strawberries, melon, and blueberries. Some herbs and spices, and certain juices like grapefruit and tomato, also contain vitamin C.
What is the role of vitamin B1 (Thiamine) in the body and what are its deficiency diseases?
-Vitamin B1 helps to release energy from food, maintaining the nervous system function and stamina. Deficiency in vitamin B1 can lead to diseases such as beriberi and ranky korsakoff syndrome.
Which foods are good sources of vitamin B1?

-Vitamin B2 promotes good vision, improves eyesight, and supports healthy and glowing skin. It is also important in converting the amino acid tryptophan into niacin. Deficiency diseases associated with vitamin B2 include ariboflavinosis, glossitis, and angular stomatitis.
How does vitamin B3 (Niacin) contribute to digestion and what are the signs of its deficiency?
-Vitamin B3 aids in digestion, improves metabolism, and supports normal enzyme function. It also promotes healthy skin and nerves. Signs of deficiency include poor concentration, memory, headache, fatigue, sore mouth, digestive problems, and skin problems.
What are the functions of vitamin B5 (Pantothenic Acid) and what are the common signs of its deficiency?
-Vitamin B5 aids in metabolism and the formation of hormones, participating in the hormonal process in the body. Deficiency signs include fatigue, lethargy, burning feet, stress, anxiety, and respiratory infections.
What is the role of vitamin B6 in protein metabolism and what are the deficiency diseases associated with it?
-Vitamin B6 aids in protein metabolism and the production of red blood cells, insulin, and hemoglobin. It also purifies blood. Deficiency diseases caused by vitamin B6 include anemia and peripheral neuropathy.
How does vitamin B7 (Biotin) contribute to energy release and what are its food sources?
-Vitamin B7 helps release energy from carbohydrates and aids in the metabolism of fats, proteins, and carbohydrates from food. Sources of biotin include peanuts, oats, hazelnuts, egg yolks, lentils, walnuts, soybeans, and carrots.
What are the functions of vitamin B9 (Folic Acid) and what are the deficiency diseases caused by it?
-Vitamin B9 aids in protein metabolism and red blood cell formation. It also reduces the risk of neural tube birth defects. Deficiency diseases caused by folic acid include megaloblastic anemia and birth defects.
What is the primary role of vitamin B12 (Cobalamin) and what are its food sources?
-Vitamin B12 aids in the production of normal red blood cells and maintains and stimulates the nervous system. It also coordinates activities in the brain. Food sources rich in vitamin B12 include burgers, yogurt, milk, lamb liver, mozzarella, lobsters, eggs, crabs, chicken, trout, salmon, and beef.
How does vitamin A contribute to bone and vision health and what are its deficiency diseases?
-Vitamin A is integral to bone and tooth formation and improves eyesight, contributing to immune and cellular function. Deficiency diseases due to lack of vitamin A include night blindness and hyperkeratosis.
What are the functions of vitamin D and what are the deficiency diseases associated with it?
-Vitamin D aids in the development of teeth and bones by encouraging the absorption and metabolism of phosphorus and calcium. Deficiency diseases caused by lack of vitamin D are osteomalacia and rickets.
What is the role of vitamin E as an antioxidant and what are the food sources of vitamin E?
-Vitamin E acts as an antioxidant that helps fight infectious diseases and keeps red blood cells healthy. Food sources of vitamin E include vegetables like broccoli and spinach, fruits like avocado and mango, cooking oils, and nuts and seeds.
How is vitamin K important for blood clotting and bone health, and what are the deficiency diseases caused by it?

π Introduction to Vitamins and Their Types
The video begins by welcoming viewers to the FoodTech Journey channel and immediately delves into the topic of vitamins. It explains that vitamins are organic molecules essential for metabolism and cannot be synthesized by the body, hence must be obtained from the diet. The paragraph introduces the concept of vitamers, which are related molecules that constitute a vitamin. It then distinguishes between two types of vitamins: fat-soluble and water-soluble. Fat-soluble vitamins, including Vitamins D, K, A, and E, are stored in the liver and adipose tissue, while water-soluble vitamins, such as Vitamins B and C, are not stored and require regular intake. The paragraph concludes by focusing on water-soluble vitamins, starting with Vitamin C, which plays a central role in iron absorption, collagen synthesis, wound healing, and immune function, with deficiency leading to scurvy. The food sources of Vitamin C are also listed, including citrus fruits, vegetables, and herbs.
π₯ Exploring the Roles and Food Sources of Water-Soluble Vitamins
This paragraph continues the discussion on water-soluble vitamins, focusing on the B-complex vitamins and their roles in the body. It covers Vitamin B1 (Thiamine), which is crucial for energy release from food and maintaining the nervous system, with deficiency leading to diseases like Beriberi. The paragraph then moves on to Vitamin B2 (Riboflavin), which is important for vision, skin health, and amino acid conversion, with deficiency diseases such as Ariboflavinosis. Vitamin B3 (Niacin) is next, highlighting its role in digestion, metabolism, and enzyme function, with deficiency signs including poor concentration and skin problems. The paragraph also discusses Vitamin B5 (Pantothenic Acid), which aids in metabolism and hormone production, and whose deficiency can lead to Paresthesia. Vitamin B6 (Pyridoxine) is introduced for its role in protein metabolism and red blood cell production, with deficiency causing anemia and neuropathy. The paragraph concludes with Vitamin B7 (Biotin) and Vitamin B9 (Folic Acid), detailing their roles in energy release, metabolism, and red blood cell formation, and the consequences of their deficiency, including anemia and birth defects. Food sources for each vitamin are provided, emphasizing the importance of a balanced diet.
π Fat-Soluble Vitamins: Storage, Functions, and Deficiencies
The third paragraph shifts the focus to fat-soluble vitamins, explaining that they are stored in the body and absorbed by fat globules. It starts with Vitamin A, which is vital for bone and tooth formation, vision, and immune function, with deficiency leading to night blindness and hyperkeratosis. The paragraph then discusses Vitamin D, which is synthesized in the skin with sunlight exposure and is essential for bone and teeth development by aiding the absorption of calcium and phosphorus, with deficiency causing osteomalacia and rickets. Vitamin E, an antioxidant, is covered next, protecting against infections and maintaining red blood cell health, with rare deficiencies potentially leading to hemolytic anemia. Lastly, Vitamin K is introduced for its importance in blood clotting and bone health, with a deficiency resulting in bleeding diathesis. The paragraph concludes by listing food sources for each fat-soluble vitamin, including vegetables, fruits, oils, and organ meats.
