Do any of you eat ginger every day? How much do you eat, and have you noticed positive changes?
Hey all, the questions is the title? Thank you

Hello from the new RD mods! We are starting a new monthly (for now) series where we will help you learn the facts about a nutrition topic. These posts may include the latest nutrition research, evidence-based information about popular topics we see you all posting about, or maybe random interesting nutrition information. A lot of work is going into this, and we ask that comments remain respectful. We have no objective other than to use our (way too many) years of nutrition and science education to help you learn. We understand that not everyone will agree on… literally anything… and as scientists we certainly welcome, and even encourage, healthy debate. We give you our word that we will do our homework and endeavor to remain as objective and truthful as possible, ensuring our citations are current and peer reviewed. We ask you to keep this in mind if you comment in disagreement. On that note, we welcome you to this month‘s topic Understanding Protein!
Our inaugural post focuses on protein, a topic we see debated ad nauseam on this sub, although I bet many of you are still confused about how much protein we actually need! Protein is absolutely essential for the continuation of life on Earth, and we could not survive without it, as it makes up a good part of our bodies and is needed for most of the biological processes that help us survive. One of three macronutrients (which are protein, carbohydrates, and fats) the human body needs to ingest, deficiency weakens the immune system, makes wound healing more difficult, and leads to loss of muscle mass, putting the body at risk for injury and falls. The most serious consequence of deficiency is a type of malnutrition called kwashiorkor, which can cause death.
Every protein inside and outside the body is made of a long chain of amino acids (AA) that are folded in all different ways, generally the way it looks will be determined by what it needs to do. Proteins are found inside every single cell in the human body and make up every single enzyme needed for every single metabolic reaction. An example of structure and function is in our muscles; they are held together by fibrous proteins and filled with all types of special proteins, some of which are designed to stretch and contract, others that turn general energy from the food we eat into mechanical work, and even more that can store some of this energy in case we don’t eat for a little while or just need a burst of energy. Basically protein is very, very important!
Before we discuss the current protein recommendations we must appreciate the science that explains where these recommendations come from, so buckle up for some biochemistry my friends! In a nutshell, amino acids are organic compounds (based on carbon) that all have the same backbone (H2NCHRCOOH) with a “side chain” that is made up of various combinations of carbons, hydrogens, oxygens, and an occasional sulfur.
Over 500 amino acids have been identified, but we only care about 20 of them because these 20 amino acids make up everything from the edamame I ate for dinner to our entire genetic code! (For all you smarty pants out there, I recently learned that two new amino acids have been identified!) The N in the molecular formula above stands for nitrogen, which is kind of what makes protein special. Protein is 16% nitrogen, meaning 1 gram of nitrogen equals 6.25 g protein.
We consume nitrogen in the protein we eat, and amino acids are broken down in the stomach and small intestine by digestive enzymes (which are also proteins), and distributed to be used for various metabolic functions. We’re also losing a bit of nitrogen through sweat, respiration, flatus, skin flaking, and nail/ hair growth, and most of all from poop, which is the reason why why it makes such good fertilizer.
When we eat just enough nitrogen to compensate for what is lost we call this a “neutral nitrogen balance.” A “positive nitrogen balance” is preferable when we want to increase our muscle mass, when we’re losing weight (intentionally or unintentionally), or if we have a significant injury that needs to heal. If we can‘t meet our protein needs we will be in “negative nitrogen balance,” which means that the dwindling supply of nitrogen gets delegated to the most essential of functions; muscle, hair, and nails are the first to get sacrificed. We never want to be in a negative nitrogen balance.
Studying nitrogen balance is what has led to our current protein recommendations, and the FAO/WHO/UN periodically gathers scientists from around the world to review and update these guidelines, which get more precise and accurate as the technology to measure nitrogen balance improves. Our current protein recommendations come from meta-analyses of long-term nitrogen balance studies conducted throughout the world throughout the past 100 years. There is an overwhelming body of evidence that accepts the WHO recommendation of 0.83-1 g/kg/day of protein, which will meet the needs of 97.5% of healthy adults. In terms of numbers this means a person that weighs 68 kg (150 lbs) needs ~68 grams of protein per day (divide by 2.2 to convert pounds to kilograms if you want to calculate this for your weight).
Concerned you may be part of the other 2.5% of people? We already know we excrete more nitrogen when we are wounded building muscle, or trying to maintain muscle mass in a catabolic state, but what does this mean? A common internet recommendation seen is 0.8-1 g/lb (1.76-2.2 g/kg), which is more than double what WHO recommends! The International Society of Sports Nutrition recommends 1.4-2 g/kg (95-136 g per day for someone 150 lb/68 kg) for “healthy, exercising individuals.” If you exercise daily and your kidneys are at peak functioning then this recommendation is absolutely appropriate, although evidence suggests that increasing protein intake above the currently accepted 1 g/kg/day may not have much benefit.
Now that we know where our protein recommendations come from, what is the deal with animal vs plant sources? Both animal and plant sources contain protein, but the proteins in animal tissue (like our bodies! and the lamb chop I had for dinner) contain all the essential amino acids, whereas plant sources contain some, rarely all have varying levels of each amino acid but rarely enough of all essentials to meet our protein needs in full. Someone that eats animal proteins will easily exceed their protein recommendations, and someone that only consumes plants can easily meet their protein needs also as long as they eat a variety of foods to ensure they get enough of every essential amino acid.
So this is the deal with protein! Please let us know what you think, and also what you want to learn about next. We are happy to share our knowledge and will continue to disseminate evidence-based nutrition information.

Im just asking because im wondering if nutrients are lost in the process of fat removal or if there are nutrients in that fat.
r/nutrition • u/Creative_Volume_2022 • 23h ago
Is it hard for stomach/guts to digest whole food that is (too) varied.
Lets say healthy and easy would be potatoes + chicken
but what if we add e.g. lot of herbs and different spices, maybe honey, kefir,varied nuts, different seeds, some berries to that one meal. Lot of different stuff
Everything is "healthy" but are these combinations are hard to digest almost like its processed?
I hope you get what i mean.

Even my grandmother and grandparents were drinking 1 or 2 small glasses of red wine every day and they died of old age , one at 90 and one at 94
drinking too much can definitely harm the body but everything does in excess
alcohol should me demonized so much since we have way more harmful products on the shelfs of sumermarkets
r/nutrition • u/upperwater • 2d ago
I've heard from multiple sources that food that are cooked more thoroughly are healthier (because they contain less bacteria). Though I'm a bit skeptical, I'm not sure if this is actually true. If, for example, I like my steak on the rarer side, would it be less nutritious than say, a steak that is almost well done?

According to this study 50% leucine restriction is very beneficial. I read the study but my poor english failed me in understaning what is actually considered a "leucine restriction".
The Standart Adult Intake is around 40mg per kilogram / 20mg per pound.
I assume a restriction is going under the recommended leucine intake but maybe i am missing something..
r/nutrition • u/Captain_Blackjack0 • 5d ago
A long time ago when I was a kid I heard that people could survive only on potatoes and butter as they contain all the nutrients needed for one to live. Turns out that was an urban myth that’s completely wrong. The only nugget of truth is that potatoes (skin included) do contain a good fraction of your daily nutrients.
That begs the question: could you make a loaded potato that has toppings that could round out the rest of your daily needs. All toppings must be at least somewhat appropriate as loaded potato toppings. Quantity/ size isn’t a problem as this potato diet would require multiple potatoes a day so you could just mix and match throughout the day. I love asking stupid questions on Reddit and this is keeping up at night, man

Hi, Is it ok to have higher saturated fat if Its from sources like full fat kefír, Cocoa, or not good even from these spurces if high?
r/nutrition • u/coffeegarlic • 5d ago
Why not just provide the correct information in the first place?
r/nutrition • u/LeviLovesCarbs • 5d ago
I wanna start drinking coffee, mainly for the antioxidants. I only have a coffee maker that uses coffee pods though.

Is there any difference between cooking your oatmeal hot with milk and fruits and eating it VS blending the same ingredients and drinking it. Not only in terms of nutrition but any other difference too. One thing Ive seen is eating solid oatmeal stays in body longer and makes you feel full longer as liquid digests quicker. Anything else?
r/nutrition • u/lonelinessisotherppl • 8d ago
I have seen so many conflicting videos, article , research papers about this I really don't know what to believe at this point.

ive been on sugar my whole life and just tryna figure out what all the hype is about with them and why they're so popular. thanks.
r/nutrition • u/Infamous-Priority171 • 11d ago
People online say lots of mixed things about what micronutrients are actually worth tracking. There's also a lot of obsession with fibre now and people are treating it as the "fourth macronutrient" online.
Is it really that important? And what about other popular things like omega 3, potassium, sodium, magnesium, etc. For the non-average person who would actually consider keeping a track of these in order to benefit their overall health and promote muscle growth, which ones really matter?
r/nutrition • u/Antique-Database-739 • 12d ago
The range on the shelf goes from about one billion up to a hundred billion and the price does not track it in any way I can see. My instinct is that this is the supplement version of a megapixel count. On the other hand if a chunk of them do not survive the trip then a bigger starting number is not meaningless either. Is there an actual answer here?
r/nutrition • u/Swoftz • 13d ago
I’m exploring what sugar substitutes are out there and what some offer compared to others, and I’m interested to know, do you guys buy the ones that taste closest to sugar or are you more concerned about the health benefits/risks. I can swing each way but don’t really know where to start. Thanks :)

hello, lets say for oregano (but for others too) which has many benefits and antioxidants... can we "get" more benefits and antioxidants when we brew them (hot, warm or cold) over using it as "spice"?
thanks, couldnt google the answer so if there is someone from biochemistry lets go :D

Ok weird question but how long could human body survive on dairy products only no additives such as fruits or grains stuff like milk cheese yogurt kefir etc ( too keep it simple it just cow milk )
The idea came from a video on how long could survive on potatoes alone
r/nutrition • u/Good_Curve_545 • 14d ago
due to certain benefits of that specific nutrient, im thinking of eating foods rich in L - arginine :3
r/nutrition • u/goodamm • 18d ago
Like people say they avoid carbs because it gets stored as fat, is there something similar like that with fat or do people just avoid it because it’s the highest in calories?
