Is a banana a vegetable? No. A banana is a fruit, and that answer comes from botany, not from the produce aisle. A fruit is the part of a flowering plant that develops from the flower’s ovary and holds the seeds. A banana forms exactly that way, so it is a fruit by definition. The … Read more
PCR primers are short, single-stranded DNA sequences — usually 18 to 25 nucleotides long — that flank the specific region of DNA you want to copy. You can find ready-made primers in published databases or commercial catalogs, or you can design your own using free software that checks for melting temperature, GC content, and unwanted … Read more
Millet is not a low-carb food. Cooked millet contains roughly 23 grams of carbohydrate per 100 grams, and even the lowest-carb varieties land close to 65 grams of carbs per 100 grams dry. That makes millet a poor fit for a strict keto diet, which typically caps daily carbs around 20 to 50 grams total. … Read more

Humans sit at the very top of the shrimp food chain. We are apex predators in that system — no other animal regularly eats us in the context of shrimp ecology. When you eat shrimp, you are taking energy that passed through algae, tiny animals, and the shrimp itself before reaching your plate. That position … Read more
Irritable bowel syndrome is diagnosed by exclusion, not by a single test. There is no blood test, scan, or biopsy that confirms IBS. Instead, clinicians identify a pattern of symptoms that fits established diagnostic criteria and then rule out other conditions that can produce similar problems. That two-part process — symptom pattern plus reasonable exclusion … Read more
Prunes are dried plums, and they are best known for one thing: helping you poop. That reputation is earned. But it undersells what prunes actually do. They deliver fiber, potassium, vitamin K, and a group of plant compounds called polyphenols in a small, shelf-stable package. Some of the strongest evidence for prunes centers on bowel … Read more
People with no legs, or with legs that no longer function, use the bathroom in whatever way matches their body, their home, and their level of independence. For many, that means transferring from a wheelchair onto a toilet using upper body strength and a transfer board. For others, it means a commode chair, a ceiling … Read more
Dopamine is a chemical messenger in your brain that helps control movement, motivation, reward, and mood. When people talk about “stabilizing” dopamine, they usually mean keeping it from swinging too high or too low — and the most reliable ways to do that are not supplements or detoxes. They are sleep, regular physical activity, protein-rich … Read more
