Chapter 1
This isn't a recipe book
This is not a recipe book. It takes mechanisms such as iron absorption, the timing of calcium, how to spread protein, and fiber and gut bacteria, and sets them onto a week of Chinese-style meals. Every meal says why it is put together this way, so you can apply the same reasoning to other meals.
It does not give gram-precise recipes (that is one-to-one work for a dietitian), it does not ask you to follow it to the letter, and it does not promise that eating this way will make you lose weight, build muscle or lower your blood lipids.
A few principles run through the week: protein at every meal, spread across the three meals; vegetables or fruit at every meal; part of the staple food swapped for whole grains, beans or tubers; better cooking oils; plant iron paired with vitamin C; high-calcium and high-iron meals kept apart; more carbohydrate on training days; and a lighter dinner, but not a skipped one.

In practice · Eight principles for the whole week
Each of the eight principles has a mechanism behind it:1. Protein at every meal: 20-40 g per meal, spread over three meals, supports muscle building better than eating it all at once. In some short laboratory studies, about 2.5-3 g of leucine at a meal (roughly 25-40 g of good-quality protein) came close to the maximum muscle-building response for that meal; this is an approximation, not a hard ceiling.
2. Vegetables or fruit at every meal: aim for a range of colors, and fiber and polyphenols come along.
3. Choose staple foods for quality: swap part of the white rice and white flour for whole grains, beans and tubers.
4. Use good fats: olive oil, rapeseed oil, nuts and fish; less animal fat and palm oil.
5. Pair iron with vitamin C: iron from plant foods is absorbed better when eaten with fruit or vegetables rich in vitamin C.
6. Keep calcium and iron apart: calcium in the same meal holds back iron absorption, so high-calcium and high-iron meals are not put together.
7. More carbohydrate on training days: a little less on rest days, with the calorie difference coming mainly out of carbohydrate.
8. A lighter dinner: but do not skip it. Foods with tryptophan, magnesium and a little complex carbohydrate at dinner may help with falling asleep in terms of mechanism; the evidence for the real-world effect is limited.
Chapter 2
How to build breakfast
Breakfast is the meal people neglect most, and the easiest to tune using mechanisms.
Why it deserves attention: after a night's sleep you have gone more than ten hours without food. A good share of the glycogen in your liver has been used, and in muscle the balance has tipped toward breakdown: more protein is being taken apart for fuel than put back. Breakfast does three things: protein restarts muscle building, carbohydrate refills liver glycogen, and vitamins and minerals stock the cofactors the day's metabolic enzymes need.
How to build it: protein (20-30 g), plus complex carbohydrate, plus a food with vitamin C or iron, plus a little good fat. The seven examples for the week each give the reason for the combination.
One practical reminder: if you are taking iron, do not have milk, yogurt or coffee at the same breakfast, because calcium and polyphenols both hold back iron absorption. Keep iron supplements or iron-rich foods 2 hours away from milk and coffee.

In practice · Seven breakfasts and why they work
Monday: oat porridge (40 g oats, 250 ml milk, 2 walnuts, a handful of blueberries)Mechanism: oat beta-glucan helps lower (low-density lipoprotein cholesterol; a health claim authorized by EFSA, the European Food Safety Authority); the milk brings 8 g of protein; walnuts provide alpha-linolenic acid (); blueberries provide anthocyanins.
Tuesday: 2 slices of whole-wheat toast, 2 boiled eggs, a few slices of tomato or avocado, 1 kiwi
Mechanism: eggs are a complete protein, with about 0.5 g of leucine per egg; avocado supplies monounsaturated fat; the kiwi's vitamin C helps absorb non-heme iron (the iron in plants).
Wednesday: mixed-grain congee (adzuki beans, mung beans, millet, brown rice), 50 g dried tofu, dressed spinach (sesame oil and vinegar), 1 orange
Mechanism: the beans supply resistant starch and fiber; dried tofu is concentrated plant protein; the non-heme iron in spinach is absorbed better with the orange's vitamin C; vinegar may make this meal's blood glucose rise more slowly.
Thursday: 200 g Greek yogurt, 10 g chia seeds, strawberries or raspberries, 10 almonds
Mechanism: Greek yogurt has about 10 g of protein per 100 g; chia seeds provide alpha-linolenic acid and fiber; almonds provide vitamin E and magnesium.
Friday: 300 ml soy milk, 1 vegetable-and-meat bun, 1 boiled egg, 5 cherry tomatoes
Mechanism: soy milk provides soy isoflavones and protein; the bun supplies carbohydrate; lycopene from tomatoes is fat-soluble and is absorbed better with the fat in the egg.
Saturday (training day): oats, 1 scoop of whey protein, 1 banana, 1 spoon of peanut butter, milk
Mechanism: a carbohydrate-plus-protein combination before training; the banana brings potassium and fast-absorbed carbohydrate; the fat in peanut butter slows stomach emptying.
Sunday: tofu pudding (light on sauce and salt), half a whole-wheat sesame flatbread, 1 egg, cucumber salad
Mechanism: tofu pudding set with gypsum (calcium sulfate) supplies calcium and protein; cucumber adds water and fiber; watch the sodium and go easy on the sauce.
Chapter 3
Spreading protein over lunch and dinner
The heart of lunch and dinner is not which dishes you eat but how protein is spread out and how iron and calcium are kept apart.
Spreading protein: the muscle building that one meal can drive has a rough upper limit. In some short laboratory studies, about 2.5-3 g of leucine at a meal (roughly 25-40 g of good-quality protein) came close to the maximum response for that meal, and eating more added limited extra benefit for that meal; this is an approximation, not a hard ceiling. So 100 g of protein over three meals beats 80 g at one meal and 10 g at each of the other two.
Keeping iron and calcium apart: calcium in the same meal holds back iron absorption. Non-heme iron from plants is hit hardest, and heme iron from meat may be lowered somewhat too; the exact mechanism is not fully worked out. The effect is clear in single-meal trials and usually shrinks within a varied everyday diet. So lunch carries the iron-rich foods (red meat, animal liver, blood products, or spinach with vitamin C), and dinner carries the calcium-rich foods (tofu, dairy, small dried fish, sesame).
A week of lunch and dinner examples follows, each labeled with the reasoning behind the combination.

In practice · Fourteen lunches and dinners
Built on a Chinese family table:Monday lunch: brown rice, tomato and scrambled egg, steamed sea bass, garlic broccoli
Sea bass supplies the omega-3 fatty acids and ; broccoli has vitamin K and sulforaphane; lycopene is absorbed better with the egg's fat.Monday dinner: mixed-grain rice, mapo tofu (with a little minced beef), kelp salad, seaweed and egg soup
Tofu supplies calcium and protein; kelp has iodine and fucoidan; nori has a little B12 and minerals.
Tuesday lunch: buckwheat noodles, cold noodles with shredded chicken and cucumber, 1 soy-braised egg, edamame
Buckwheat has rutin; the chicken supplies protein; edamame are young soybeans, whose protein has a fairly complete amino-acid profile.Tuesday dinner: millet congee, steamed salmon, spinach stir-fried with garlic, steamed pumpkin
Salmon has omega-3; spinach has iron and folate; pumpkin has beta-carotene.
Wednesday lunch: rice, stir-fried shredded pork with green pepper (lean pork), tomato and egg soup, stir-fried water spinach
Lean pork has heme iron and zinc; the vitamin C in green pepper helps iron absorption.Wednesday dinner: sweet potato, shrimp and tofu casserole, Wood Ear Mushroom mushroom salad, stir-fried romaine lettuce
Sweet potato has beta-carotene and fiber; shrimp supply zinc and protein; Wood Ear Mushroom mushroom has soluble fiber.
Thursday lunch (training day): beef rice bowl (thin-sliced beef, onion, rice), miso soup, avocado salad
Beef has creatine, heme iron and zinc; carbohydrate plus protein after training.Thursday dinner: whole-wheat pasta, chicken breast, tomato sauce, Parmesan, lettuce salad
Chicken breast supplies protein; tomato has lycopene; the cheese supplies calcium.
Friday lunch: 15-20 dumplings (pork and napa cabbage, or chive and egg), a cold side dish
Dumplings wrap carbohydrate, protein and fat together; go easy on salt in the dipping sauce.Friday dinner: purple-rice congee, clear-stewed pork ribs (fat skimmed off), stir-fried zucchini, dried-tofu salad
The ribs supply protein and minerals (the broth holds little nutrition; eat the meat); purple rice has anthocyanins.
Saturday lunch: chicken curry (chicken thigh, potato, carrot, onion, curry powder, a little coconut milk), brown rice
Curry contains curcumin, and piperine from black pepper can raise its absorption. The often-quoted 20-fold increase comes from a pharmacokinetic study that measured blood levels after 2 g of purified curcumin with 20 mg of piperine, not a clinical benefit; a plate of curry contains far less. Chicken thigh supplies protein and iron.Saturday dinner: steamed cod, lotus-root and pork-rib soup (fat skimmed), stir-fried Chinese broccoli, mixed-grain rice
Cod has the omega-3 fatty acid DHA; Chinese broccoli has calcium and vitamin K; lotus root supplies fiber.
Sunday lunch: hot pot (clear broth), lean beef slices, fish fillet, tofu, plenty of vegetables, a few glass noodles
Hot pot can be very healthy: choose a clear broth, plenty of vegetables and protein, few processed balls; use vinegar and crushed garlic for dipping and less sesame paste.Sunday dinner: vegetable congee, steamed egg custard, cucumber salad, a little soy-braised beef
A light dinner; the egg custard's protein is easy to digest; the braised beef supplies protein and iron.
Chapter 4
Snacks & timing
Snacks are not required. They help in four situations: around training, when meals are more than 5 hours apart, when the day's total protein falls short, and when you need help getting to sleep.
Around training: 1-2 hours before training, eat carbohydrate with a little protein, and keep fat and fiber low so your stomach is not full while you exercise. The famous 30-minute window after training is a myth; what matters more is not leaving too long between the meals before and after training, and getting enough protein over the day. If it is convenient, 20-30 g of protein plus carbohydrate within 1-2 hours after training helps recovery.
The bedtime snack's mechanism is worth spelling out: tryptophan is the raw material for serotonin and melatonin, but to reach the brain it must compete with several other amino acids for the same transporter, and usually it loses. A little carbohydrate triggers a little insulin, insulin moves those competitors into muscle, and tryptophan's path clears. That is why the classic combination is warm milk with two whole-wheat crackers, not milk on its own. The mechanism makes sense; how much it actually helps sleep is less well supported. Magnesium and glycine work by another route, helping the nerves settle.

In practice · What to eat at each time of day
Before training (1-2 hours): carbohydrate with a little protein, and not much fat or fiber (to avoid an upset stomach)1 banana and 1 boiled egg1 slice of whole-wheat bread with peanut butterA low-sugar oat energy bar
After training (within an hour or two): 20-30 g of protein plus carbohydrate. The window is not the fabled 30 minutes, but refueling within 1-2 hours after training does help recovery
1 scoop of whey protein and a bananaChocolate milk (carbohydrate to protein roughly 3:1 to 4:1)A chicken breast sandwich
Afternoon snack (if you are hungry):
A small handful of nuts (20-30 g, mixed walnuts, almonds and cashews)Greek yogurt with blueberriesAn apple with peanut butterEdamame1-2 boiled eggs
Bedtime snack (if you need one):
200 ml warm milk with 2 whole-wheat crackers (the classic tryptophan-plus-carbohydrate combination)Chamomile tea and a small handful of almonds (almonds contain magnesium; chamomile is mildly calming)2 kiwis: in a small study in Taiwan, Lin 2011 had 24 adults with sleep problems eat 2 kiwis 1 hour before bed for 4 weeks, and their sleep onset and sleep quality improved; but there was no control group and the sample was small, so treat it as a lead only.Tart cherry juice (a natural source of melatonin; weak evidence)

In practice · When to take creatine and iron
If you take creatine: 3-5 g a day, and the timing does not matter much (on an empty stomach or with meals); taking it with carbohydrate may slightly increase how much creatine muscle stores (insulin helps creatine into muscle). A loading phase is not necessary, but loading (20 g a day for 5 days) fills the muscle's creatine stores faster.Iron supplements: if a doctor has prescribed iron, it is usually taken in the morning on an empty stomach. Moretti 2015 measured this in young women with low iron stores: a single dose of 60 mg or more raised hepcidin, a hormone that shuts the gut's door for iron, for about 24 hours, and cut absorption of the next day's dose by 35-45%. The authors concluded that taking it every other day may be better, and that the long-term effects still need study. Take iron with vitamin C (a 100 mg tablet or a glass of orange juice), and keep it 2 hours away from calcium tablets, coffee, tea and milk. If it upsets your stomach, you can take it with a little food: less is absorbed, but it is easier to keep up.

Chinese-table specifics
Chinese eating has its own strengths and traps, and a Western template cannot simply be laid over it.
The strengths are real: far more variety and quantity of vegetables than in Western diets; plenty of soy foods (tofu, soy milk, dried tofu, tofu skin); steaming, boiling, stewing and stir-frying are all common, not just deep-frying; and congee and soups supply water and fiber.
The traps are real too; the four biggest are:
1. Too much white rice and white flour: a bowl of rice is about 200 kcal, almost all refined carbohydrate, and raises blood glucose quickly. Swapping 1/3 to 1/2 of it for mixed grains is the simplest improvement.
2. Too much sodium: soy sauce, oyster sauce, chili bean paste, pickles and cured meat can put 1000 mg of sodium into a single dish.
3. Too much cooking oil: a tablespoon of oil is about 120 kcal; the Chinese Dietary Guidelines recommend 25-30 g of cooking oil a day, and many people use more.
4. The soup myth: bone broth holds very little calcium (in one analysis, a whole serving held only about 15 to 40 mg, under 5% of daily needs), and milky-white soup is emulsified fat; the nutrition is in the meat, not the soup.
One safety reminder: ingredients in medicinal soups and traditional Chinese medicine can interact with Western drugs or supplements (ginseng with glucose-lowering drugs, ginkgo with anticoagulants, for example). If you are on medication, do not add remedies on your own.

In practice · Eight traps and simple swaps
Strengths of Chinese eating:Far more variety and quantity of vegetables than Western diets (leafy greens, nightshades, mushrooms, roots)Plenty of soy foods (tofu, soy milk, dried tofu, tofu skin, fermented tofu)Varied cooking methods (steaming, boiling, stir-frying, stewing), not just deep-fryingBoth individual plates and shared dishes, which is flexibleCongee, soups and thick broths supply water and fiber
Traps in Chinese eating:
1. Too much white rice and white flour: a bowl of rice is about 200 kcal of refined carbohydrate with a high glycemic index (, how fast a food raises blood glucose). Swapping 1/3 to 1/2 for mixed grains (brown rice, millet, adzuki beans, oats) is the simplest improvement.
2. Too much sodium: soy sauce, oyster sauce, chili bean paste, , pickles and cured meat can put 1000 mg of sodium into a single dish. The US Dietary Guidelines set an upper limit of < 2300 mg of sodium a day; the Chinese Dietary Guidelines 2022 advise no more than 5 g of salt a day (about 2000 mg of sodium); people with high blood pressure are often advised to go lower, for example 1500 mg. Use vinegar, lemon, garlic, ginger and spices in place of some of the salt and soy sauce.
3. Too much cooking oil: a tablespoon of oil is about 120 kcal. The Chinese Dietary Guidelines 2022 (core recommendation five) advise 25-30 g of cooking oil a day (about 2-3 tablespoons), but many people use more. Use an oil sprayer and a non-stick pan, and switch some stir-fries to steaming and boiling.
4. Over-refined breakfasts: white congee, steamed buns and pickles raise blood glucose quickly, are high in sodium and low in protein. Add eggs, milk or soy.
5. The soup myth: bone broth holds very little calcium (in one analysis, a whole serving held only about 15 to 40 mg, under 5% of daily needs) but plenty of purines and fat; eat the meat rather than drinking the soup. Milky-white soup is emulsified fat, not nutrition.
6. Eating an organ to nourish the same organ: there is no scientific basis. Eating kidney does not strengthen your kidneys, and eating brain does not feed your brain (pork brain is in fact very high in cholesterol).
7. Medicinal soups and tonics: many Chinese herbs interact with Western drugs and supplements (ginseng with glucose-lowering drugs, ginkgo with anticoagulants, for example); do not add remedies on your own.
8. Banquets and takeout: oil, salt and sugar all run high. At banquets, eat more vegetables and protein and less soup and sauce; for takeout, choose steamed or boiled dishes and eat only half the rice.
Snack swaps:
Cookies and cake: swap for nuts, fruit or yogurtMilk tea: swap for unsweetened tea, black coffee or sparkling waterPotato chips: swap for edamame, roasted seaweed or baked sweet potatoHam sausage and cured meat: swap for boiled eggs, chicken breast or dried tofu
Takeout tips:
Steamed, boiled and stewed first, stir-fried second, deep-fried lastAsk for less oil and less saltEat only 2/3 of the riceAdd a side of blanched greensDo not drink the noodle broth (most of the sodium is in it)

Chapter 6
Eating on training and rest days
Eating does not need to be the same every day. On training days and rest days the body needs different things.
Why: strength training digs a hole in the glycogen stored in muscle and leaves a batch of small injuries in the muscle fibers to repair. Glycogen is refilled with carbohydrate, and repair is done with amino acids. So the extra 200-400 kcal on a training day should come mainly from carbohydrate, not from fat or more protein. Protein just stays steady every day; it is not something only training days need.
Rest days are the reverse: carbohydrate comes down and protein does not. Muscle is repaired over the day or two after training, so rest days are exactly when the building work happens.
During a fat-loss phase the most important thing is not protein but training intensity. In an energy deficit, the first way to keep muscle is to keep lifting close to your usual weights; eating a bit more protein is the second layer of insurance.

Numbers · How much to eat in each phase
Training days (strength training or high-intensity intervals):Calories: 200-400 kcal more than on rest days, mainly from carbohydrateCarbohydrate: 4-6 g/kg (300-460 g for a 77 kg person), concentrated around trainingProtein: 1.6-2.2 g/kg (125-170 g for a 77 kg person), over 3-4 mealsFat: 0.8-1 g/kg, relatively low1-2 hours before training: carbohydrate plus protein, low in fat and fiber1-2 hours after training: 25-40 g of protein and 0.5-1 g/kg of carbohydrateCreatine: 3-5 g (every day, not only on training days)
Rest days:
Calories: maintenance, or a small deficit (if you are losing fat)Carbohydrate: 2-3 g/kg, mainly from whole grains, tubers and legumesProtein: keep to 1.6-2.0 g/kg (rest days still need protein for repair)Fat: 1-1.2 g/kg
During a fat-loss phase:
A deficit of 300-500 kcal a day (no more than 700)Raise protein to 2.0-2.4 g/kg to help keep muscleKeep training intensity up (this is the first thing that preserves muscle, not protein)Do not let carbohydrate drop too low (< 100 g a day often drags down hard training) (beta-hydroxy-beta-methylbutyrate, a breakdown product of leucine) at 3 g a day: the International Society of Sports Nutrition (ISSN) position stand of 2013 (Wilson 2013) mainly says it can reduce muscle damage from training and aid recovery, and advises taking it around workouts; it does not make HMB a standard part of keeping muscle during fat loss, and several of its authors report industry funding.Keep taking creatine as usual (3-5 g a day)
During a muscle-gain phase:
A surplus of 200-400 kcal a day (do not go above 500 in a dirty bulk; too much fat comes with it)Protein 1.6-2.2 g/kg (eating more protein does not automatically build more muscle)Carbohydrate 5-7 g/kg (fuel for training)Sleep 7-9 hours (much of the repair and muscle building that training sets off happens during rest and sleep afterwards)
An example of spreading training and rest days over a week:
Train Monday, Wednesday and Friday: higher carbohydrate on those daysLight activity Tuesday, Thursday and Saturday: moderate carbohydrateRest on Sunday: lower carbohydrateProtein stays the same every day
Remember: supplements are the third layer. Get training intensity, total protein, sleep and total calories right, and then supplements can matter; the other way round, supplements cannot make up for too little training or too little sleep.
Chapter 7
Supplements in your day
If you take supplements, this chapter is about fitting them sensibly into your day.
Why timing matters comes down to three principles:
Fat-soluble ones travel with fat: vitamin , and fish oil are fat-soluble and are absorbed better with a meal that contains fat.Separate the ones that hold each other back: calcium taken at the same time holds back iron absorption, so calcium goes with dinner and iron in the morning on an empty stomach; the polyphenols in tea and coffee also hold back iron, so keep them apart too.For anything that affects alertness, look at how long it lasts: caffeine's half-life is about 5 hours (it varies a lot between people), so a cup late in the afternoon eats into that night's deep sleep; B vitamins go in the morning; sleep aids go before bed.
Three firm reminders: fill gaps first, then add things for specific goals; supplements cannot replace diet, training and sleep; if you have a medical condition or take medication, ask a doctor or pharmacist before adding any supplement; pregnant and breastfeeding women and children should take supplements only under medical guidance.

In practice · A daily supplement timetable
Morning (with breakfast):Vitamin , 2000-4000 (absorbed better with a meal containing fat; 4000 IU is the adult tolerable upper intake level, , so do not go higher)Vitamin (), 100-200 mcg (often taken with D3; it helps some proteins in bone bind calcium, but steering calcium into bone is a mechanistic claim, not a trial result)B-complex (if you take it, in the morning with food; B vitamins can affect sleep)Fish oil, 1-2 g of plus (with food, which means fewer fishy burps)
30-60 minutes before training:
Caffeine, 3-6 mg/kg (230-460 mg for a 77 kg person). A 240 ml cup of ordinary brewed coffee has about 95 mg of caffeine, so this equals two and a half to five cups, which is already a lot for many people; if you get palpitations, feel anxious or sleep badly, stay at the low endBeta-alanine (if you do high-intensity intervals of 1-4 minutes): 4-6 g a day in total, split into doses of about 1.6 g, ideally with meals, so it need not go before training; like creatine, it has to be taken for weeks (at least 2 to 4) to work
After training or with a meal:
Creatine, 3-5 g (any time; slightly better with carbohydrate)
Between meals or on an empty stomach:
Iron supplement (if needed): in the morning on an empty stomach, possibly every other day, with vitamin C, and 2 hours away from calcium, coffee and tea
With dinner:
Calcium, 500 mg (if your diet falls short; dinner suits it because it keeps calcium away from iron)Magnesium, 200-400 mg (glycinate or threonate, at dinner or before bed). Note: for adults, the tolerable upper intake level (UL) for magnesium from supplements is 350 mg a day, and magnesium from food does not count; above 350 mg you are past the UL and diarrhea becomes likely, so use higher doses under medical guidance, and check with a doctor first if your kidneys do not work well
30-60 minutes before bed:
Glycine, 3 g (in a small trial by Yamadera 2007, participants rated their sleep quality as better)Ashwagandha KSM-66, 600 mg a day (if you are under a lot of stress): Chandrasekhar 2012 was a single-center randomized double-blind trial in 64 adults with chronic stress, taking 300 mg twice a day for 60 days, whose stress-scale scores fell more than with placeboMelatonin, 0.5-1 mg (for jet lag or trouble falling asleep; start low, as a higher dose is not necessarily better)
Myth · Supplements not worth taking every day
Not recommended every day:Multivitamins (most people with a balanced diet do not need them; multivitamin trials have not shown lower death from all causes)Vitamin C (more than 100 mg a day is easy to get from food; supplements do not prevent colds and may shorten them very slightly)Branched-chain amino acids () (redundant once you eat enough protein)Glutamine (no extra benefit for healthy people who train)Fat burners (the only ingredient that works is caffeine; just drink coffee)
Key principles:
1. Fill gaps first (if you really are short of vitamin D, omega-3 or magnesium), then add things for specific goals
2. Supplements cannot replace diet, training and sleep
3. If you have a medical condition or take medication, ask a doctor or pharmacist before adding any supplement
4. Pregnant and breastfeeding women and children should take supplements only under medical guidance

What this story wants to give you is not a menu but the ability to read a menu: once you understand the mechanisms, you can make better choices in any restaurant, any supermarket and your own kitchen.

Safety · Who should check with a doctor first
In the situations below, think one step further before copying general dietary advice:People with diabetes, kidney disease, liver disease, cardiovascular disease, digestive disease or another chronic illness must discuss dietary changes with a doctor or registered dietitian first.Pregnant and breastfeeding women, children, teenagers and older adults have different nutritional needs and need individual guidance.People with food allergies or intolerances (lactose intolerance, celiac disease, sensitivity to , the short-chain carbohydrates that some people digest poorly, and so on) should decide what to cut out with a doctor or dietitian.The supplement suggestions here are general information, not medical advice; people taking medication should pay particular attention to interactions between drugs and supplements.Weight goals (building muscle or losing fat) should be adjusted with your training plan and your body's feedback; do not chase numbers blindly.
Know what to do and why: once you understand the mechanism behind each meal, you can put together a sensible meal yourself in a different restaurant, a different season or with different ingredients.

Pharmacokinetic study, not a clinical-outcome trial (kind changed from rct to mechanism on 2026-09-24). Rats: curcumin 2 g/kg with piperine 20 mg/kg raised bioavailability by 154%. Healthy human volunteers: 2 g curcumin alone gave undetectable or very low serum levels; adding 20 mg piperine produced much higher concentrations from 0.25 to 1 h after the dose, a 2000% increase in bioavailability, with no adverse effects. The abstract gives neither the number of volunteers nor whether the human comparison was randomized (abstract, PMID 9619120). 10.1055/s-2006-957450

Journal of the International Society of Sports Nutrition, 14, 18. Position stand: short- and long-term creatine supplementation, up to 30 g/day for 5 years, is safe and well tolerated in healthy individuals and in a number of patient populations from infants to the elderly; the stand adds that significant health benefits may come from ensuring a habitual low-dose creatine intake (e.g., 3 g/day) throughout the lifespan (abstract, PMID 28615996). 10.1186/s12970-017-0173-z

Blood, 126(17), 1981–1989. 54 nonanemic young women with plasma ferritin <= 20 µg/L, isotope-labelled ferrous sulfate 40-240 mg at 8:00 fasting. 24 h after doses >= 60 mg, hepcidin was raised and fractional absorption of the next dose fell by 35-45%. A sixfold dose increase (40-240 mg) gave only a threefold rise in iron absorbed (6.7-18.1 mg). Three 60 mg doses (2 mornings and an afternoon) were not significantly better absorbed in total than 2 morning doses. Authors: lower doses (40-80 mg) and avoiding twice-daily dosing maximize fractional absorption; the hepcidin time course supports alternate-day dosing, whose longer-term effects need study (abstract, PMID 26289639). 10.1182/blood-2015-05-642223

Journal of the International Society of Sports Nutrition, 10, 6. Position points: HMB can enhance recovery by attenuating exercise-induced muscle damage; take it close to the workout, ideally for 2 weeks before an exercise bout; 38 mg/kg body mass daily; HMB-FA may raise plasma HMB more than HMB-Ca, but research is too limited to say one form is superior; chronic use is safe. The text puts dietary sources in perspective: over 600 g of protein would be needed to supply the 60 g of leucine that yields the typical 3 g/day HMB dose. Equivalent doses of HMB-FA (0.8 g) vs HMB-Ca (1.0 g) gave double the peak plasma level in a quarter of the time (30 vs 120 min); suggested timing 30-60 min before exercise for HMB-FA and 60-120 min for HMB-Ca. Its two tables summarise HMB studies only; there is no table ranking supplements. Several authors report industry funding (abstract, PMID 23374455; full text, PMC3568064). 10.1186/1550-2783-10-6
