Hey, any med student or practitioner here? Just want to ask why milk is not recommended for adults, why does people say it makes the bone brittle, on contrary I have read passages about how calcium strengthens bone? Tbh, I've read several professional books but I still haven't got any evidence on it. I first heard this with our professor but he didn't explain further, but once I had a chance I asked one of our professor which is a doctor and our professor said that in adults especially in elderly, calcium is really needed, but it was contrary to what our previous prof said, and tbh I'm more inclined with that statement that calcium makes the bone stronger. I was actually searching for the principle and mechanism of how excess calcium or milk can make the bones brittle but I haven't seen any trusted source of it yet. I just want to listen to other POV, and to expand my knowledge of course since I actually saw a post recently that debates this topic, but their comments are just a sentence of 2 so it didn't really explain anything properly. PS. You may ask why I'm asking when I already asked our prof. It's not like I don't believe or something but I was just curious on it's principle and mechanism since neither of them really explained it throughly.
Lactose is a normal part of a human diet up to about age 3. It's the main sugar in milk, including human breast milk. To digest it, you have to make an enzyme called lactase; almost everyone has this as a baby and toddler (and if you don't, that indicates a problem.) Some people, though, lose the ability to produce lactase when they get older; some retain it. That doesn't address the deeper health issues involved, but "lactose is terrible for human consumption" - ehh, it depends. It's fine for babies. It's at least digestible for some adults. If you can't digest it properly, well yeah, you should avoid it. Beyond that, nutritional science and recommendations are a mess. It's impossible to do double-blind studies for long periods of time when it comes to diet and sometimes you can't even do short-term ones, depending on what you're measuring. So nutritional studies are usually just observations. They can show that milk consumption correlates to early death (if that's true) but can't show that milk CAUSES it. Only that they often come together, statistically speaking. It could be that people who are already ill tend to choose milk more often, in an attempt to be healthier. It could be that drinking milk makes some people think that since they drink natural beverages they think are healthy, they don't have to monitor their diets as carefully. It could be that milk isn't the problem, but some foods commonly consumed with milk are harmful (cereal, cookies, generous amounts of vodka and Kahlua... maybe that last one is just me...) Or any of several other possibilities. A simple correlation won't differentiate between any of those explanations and "milk is bad." There's very little in nutrition that's settled science. Almost everyone agrees that vegetables are good for you and processed junk food shouldn't be a dietary staple. Beyond that, it's hard to be sure - correlations are all over the place. Shorter version: nobody really knows. Nutrition is an area of research that is notorious for flipping its recommendations frequently and having different scientists come to different conclusions. Part of this is because it's very difficult to tease out all the possible explanations for what you see.
Calcium strengthens bones There is no anti-calcium in milk if anti-calcium is a thing I’m not an expert but I don’t think there is an explanation for it being deeper than it having calcium
I heard of lactose intolerant people but what you are talking about might be a sham to encourage people to not consume animal products and more consume vegetable based products, you should probably check if your prof is a vegan or not before pondering much about that matter
If I believed every recommendation on food I got from the so called latest research, the only danger I would be in would be of starvation. These guys keep flipping their suggestions faster than I can flip my omelette.
I just want to share the rebutals on this that I have read to that prior debate which really don't explain anything. Allegedly this is their defence (NOT MINE!) 1. It has to do with lactic acidosis. 2. Excess calcium actually extract the existing calcium on the bones when Vit D is lacking. (I felt dumb with this statement tbh, cause I can't really connect the dots with it. But, I'm not sure either if it was just too advance or it was just a myth) Well, I maybe biased with pro Calcium but I won't rebut them either. But believing and counter research in another thing .
I believe the issue is with calcium, not lactose. You can't just get rid of excess calcium through urination. Kids need it to grow brones and the excess is store there. When you're an adult you stop growing so you don't need a lot of calcium unless you're pregnant. Too much calcium will made the bones stiff and brittle, and/or make you grow a bone spur (mostly for old people).
I am not a medical professional, but I am a specialist at petting cats! It has already been mentioned of milk and lactose and lactase. As for calcium, I think it is a matter of cofactors. I remember long ago hearing a story how too much calcium pretty much made a dog immobile due to their bones. And after feeding them I think phosphorus? The dog got better? It has been a story from long ago and my memory regarding anything not related to cats isn't that good... end of the day, calcium alone is bad without the cofactors with it.
The thing about most pro-milk studies published is that they are funded by the dairy industry. What you need to find is studies on the long term effect of lactose on lactose intolerant people. As 70% of the world is just that. If you aren't 100% from European decent, you're most likely intolerant in some capacity. If you are totally white, good chance you can disregard this. For me(half Asian, half Brit), as a person who gets diarrhea from milk, I'd say I absorb very little of the calcium, as I'm on the can 30 minutes later. I'm far more likely to get calcium from food that stays in me. Like from tofu, kale, and various seeds and nuts I like to eat. One must consider what their body can handle before worrying about questionable studies. Also remember, humans around the world are just fine not having milk for millennia , it's the filler snacks with no nutrition that are screwing with people imo.
I think i remember this in college. Too much calcium makes the bone, brittle. Its like adding more cement to a foundation when its already been set-up. You need to get a specialist to do some test if your body have enough calcium or your overloaded with it.
Me, who is 100% of European descent and has the DNA results to prove it and was recently proven to have become lactose intolerant: …
It's healthy, milk does help with calcium and is usually fortified with vitamin D to help with calcium absorption. It dose help with building more dense bones when you are young then to preserve them when you are older. According to this study 68% of the world population has trouble digesting lactose. Though it is mainly for those in Africa and parts of Asia where milk was historically difficult to get, so it was rarely consumed. I mention this because researchers have a fair amount of evidence that for at least part of those who have trouble digesting lactose, it could be from a mother not drinking milk during pregnancy or not drinking milk consistently as they get older that could cause the lactose malabsorption. This study also found that exposed to terms was good for babies as it builds their immune system and avoiding giving children foods for fear of an allergy (peanuts) could result in a development of a peanut allergy ( the study emphasize that this is not the case for everyone and for some, you were just going to be allergic to peanuts no matter what). If you have a condition that makes you absorb too much calcium, then yes, it will make your bones brittle. It's usually caused by a problem in your thyroid, but for the most people you will just pee out the extra calcium. Though most people don't even get enough calcium in the regular diet for this to even be a concern. Sum it up: possible yes, likely? No.
If you drink too much milk your skeleton will become too powerful and escape your body. Never drink milk. Supress the skeleton army.
Sorry to say I think it's the opposite. The more "pure" or " less diversified " you are genetically, the more likely you are to have food allergies are allergies in general, as well as other medical conditions.
Nonsense. Ai-chan, Waiwai and Iris drank breast milk regularly. Nothing happens to us. Except being horny, but that's not because of breast milk.
