XXI. Practical tips for including group B vitamins in your diet
Here are a few practical tips to include group B vitamins in your diet:
- Use a diverse and balanced diet rich in products containing B vitamins B.
- Include animal products in your diet, such as meat, poultry, fish, eggs and dairy products.
- Use many green leafy vegetables, legumes, nuts and seeds.
- Choose whole grain products instead of processed grain products.
- Consider the possibility of taking B vitamins, if you have a shortage or increased need.
- Consult with your doctor to determine the optimal doses and use of group B vitamins for your individual needs.
XXII. The debunking of common misconceptions about group B vitamins
- Treatment: More vitamins of group B are better.
- Reality: Reception of very large doses of some vitamins of group B can cause side effects. It is important to adhere to the recommended doses.
- Treatment: B vitamins can cure everything.
- Reality: B vitamins are important for health, but they are not a miraculous cure for all diseases.
- Treatment: B vitamins are necessary only for older people.
- Reality: B vitamins are necessary for everyone at any age.
- Treatment: You can get all the necessary B vitamins from enriched products.
- Reality: Although enriched products can be a good source of B vitamins, they should not be the only source. It is important to use a diverse and balanced diet.
XXIII. The role of genetics in the impact on vitamin B status
Genetics plays a significant role in metabolism and the use of group B vitamins. Genetic variations can affect the absorption, transport and transformation of these vitamins into their active forms. For example, polymorphisms in the MTHFR gene (methylentetrahydrofolateredocutase) can affect the body’s ability to turn folic acid into its active form, 5-methylhetetrahydropulat (5-mthf). This can lead to a deficiency of a folate, even if the consumption of folic acid is adequate. Similarly, genetic variations can affect the absorption and transport of vitamin B12. Understanding the genetic predisposition of a person can help adapt dietary and additional recommendations on optimizing the status of vitamins of group B.
XXIV. B vitamins and oxidative stress
Oxidative stress, an imbalance between the production of free radicals and antioxidant protection of the body, plays a role in many chronic diseases. Some B vitamins have antioxidant properties and can help protect the cells from damage caused by oxidative stress. Riboflavin (B2), for example, acts as a cofactor of enzymes involved in the restoration of glutathione, a key antioxidant in the body. Niacin (B3) is involved in the production of NADPH, molecules necessary for antioxidant reactions. Maintaining the adequate status of group B vitamins can help maintain antioxidant protection of the body and reduce the risk of chronic diseases.
XXV. The effect of cooking on the content of B vitamins
The water -soluble nature of B vitamins makes them susceptible to losses during cooking. Boiling vegetables can lead to a significant loss of B vitamins, since they are lered into water for cooking. Steaming methods, frying and microwave oven can help save more vitamins of group B. In addition, reducing the time of cooking and using the minimum amount of water can also minimize the loss of vitamins. Storage of products in a cool, dark place can also help maintain their content of vitamins of group B.
XXVI. B vitamins and drug interactions
Some drugs can interact with group B vitamins, affecting their absorption, metabolism or excretion. For example, metformin, usually used to treat type 2 diabetes, may violate the absorption of vitamin B12, which leads to deficiency over time. Proton pump inhibitors (IPP) used to reduce acid production in the stomach can also reduce the absorption of vitamin B12. Certain antibiotics can affect the production of vitamin B12 bacteria in the intestines. It is important to know about potential medicinal interactions and consult a doctor or pharmacist to evaluate and solve any fears.
XXVII. The role of the intestines in the status of B vitamins
Microbia intestinal plays an important role in the synthesis and assimilation of certain B vitamins B. Some intestinal bacteria can produce vitamins, such as biotin (B7) and vitamin B12. However, the number of vitamins of group B produced by intestinal bacteria can be insufficient to meet the needs of the body, especially in the case of vitamin B12, which is produced only by some bacteria, and may not be absorbed effectively in the intestines. Maintaining a healthy intestinal microbioma by means of a diet rich in fiber, and probiotics can support the production of group B vitamins and general health.
XXVIII. B vitamins and sports results
B vitamins are necessary for the production of energy and sports results. They participate in the metabolism of carbohydrates, fats and proteins, providing fuel necessary for physical activity. Tiamin (B1), Riboflavin (B2) and Niacin (B3) play a key role in energy generation, while vitamin B6 is involved in the metabolism of amino acids and the synthesis of hemoglobin, which transports oxygen to the muscles. Athletes may need more B vitamins due to their increased energy consumption and losses with later. However, taking additives with group B vitamins does not necessarily improve the results if there is no deficit. For athletes, it is important to consume a balanced diet rich in products containing group B vitamins in order to satisfy their needs.
XXIX. B vitamins and mental health
B vitamins play an important role in the function of the brain and mental health. They participate in the synthesis of neurotransmitters, such as serotonin, dopamine and norepinephrine, which regulate mood, sleep and cognitive functions. The deficiency of group B vitamins, especially folic acid (B9) and vitamin B12, was associated with an increased risk of depression, anxiety and other disorders of mental health. Addresses with group B vitamins can be useful to alleviate the symptoms of depression in people with deficiency, but they should not be used as a replacement for the traditional le
