What are the symptoms of a B2 deficiency?

vitamin B2 deficiency symptoms

Vitamin B2, also known as riboflavin, consists of an isoalloxazine ring connected to ribitol. Riboflavin is resistant to heat, but light can be broken down by light.

This vitamin has two coenzyme forms: FMN (flavin mononucleotide) and FAD (flavin adenine dinucleotide). FAD and FMN are involved in oxidation-reduction reactions and act as electron carriers. Enzymes that contain FAD or FMN are referred to as flavoproteins. Flavoproteins, such as alpha-amino acid oxidase, xanthine oxidase, succinate dehydrogenase, and dihydrolipoyl dehydrogenase, are enzymes involved in various biological processes. Yeast, liver, and kidney are rich in this vitamin.

Nuts are a good source of dietary fiber, which can help prevent and relieve constipation. However, nuts can also be hard to digest if you don’t chew them well or eat too many of them. Therefore, the answer to your question(do nuts cause constipation) is: it depends. Some factors that may affect how nuts influence your bowel movements: The type and amount of nuts you eat : Some nuts, such as almonds, pistachios, and walnuts, have more fiber than others, such as cashews, macadamias, and pecans. Eating a moderate amount of nuts (about a handful) can provide enough fiber to stimulate your gut, but eating too many nuts (more than 1/4 cup) can cause bloating, gas, and indigestion. The way you prepare and eat nuts : Raw nuts may have more nutrients and antioxidants than roasted nuts, but they may also contain anti-nutrients, such as phytic acid and tannins, that can interfere with digestion and absorption of minerals. Soaking, sprouting, or roasting nuts can reduce these anti-nutrie...

Can high blood pressure during pregnancy harm baby and mother?

Yes , high blood pressure during pregnancy can harm your baby . High blood pressure during pregnancy can have serious consequences for both the mother and the fetus. If this condition is not diagnosed in a timely manner, both the mother and the fetus are at risk of serious complications. High blood pressure during pregnancy can damage the paired arteries, which can cause decreased blood and oxygen supply to the fetus and slow down its growth. Sometimes, high blood pressure during pregnancy is uncontrollable, and doctors are forced to terminate the pregnancy and deliver the premature fetus. These infants are at risk, as some of their organs, such as the lungs and digestive system, are not yet fully developed, and as a result, they may be vulnerable to injury. To complete the development of their organs, they must be kept in the neonatal intensive care unit. The presence of the fetus in the neonatal intensive care unit in such cases is often long-term and sometimes lasts up to 20...

Do potatoes cause constipation?

Image
  Short answer: the answer to whether potatoes cause constipation is not straightforward. However, potatoes don’t usually cause constipation. Potatoes are starchy vegetables with many health benefits, such as vitamin C, potassium, and fiber. Fiber is essential for preventing and relieving constipation, as it helps soften the stool and make it easier to pass. Therefore, potatoes do not cause constipation when eaten in moderation and as part of a balanced diet. However, some factors may affect how potatoes impact your bowel movements. For example, preparing and cooking potatoes can change their fiber content and nutritional value. Fried potatoes, such as french fries or chips, may have more fat and salt than baked or boiled potatoes, slowing digestion and worsening constipation. Also, peeling potatoes can reduce their fiber content, as most fiber is in the skin. Another factor to consider is how potatoes interact with other foods in your diet. Some people may have fo...
