According to this article, it is noted that the best time to drink milk is at night.

In this discussion, dr. Sjoekri Rini replied that the milk contains the amino acid tryptophan, a precursor to the neurotransmitter serotonin which is useful. The nature of this alone is calming neurotransmitter that helps the sleep process more quickly.

Meanwhile, according to nutritionists Stikes Husada Banjarbaru Borneo, Nor Hasanah, adding that the calcium in milk is one of the best nutrients for maintaining bone health as calcium is more readily absorbed. So that, for the most milk should be consumed at night. In the evening, osteoclasts, or cells of the bone destruction does not work. In addition, our activities in the evening is also limited so that the calcium of milk will be absorbed optimally.

1 Answer 1

The research whether the best time to drink milk is at night is inconclusive since human trials for this hasn't been yet observed or reported.

The functional foods promoting sleep in human beings are barley grass powder, whole grains, maca, panax, Lingzhi, asparagus powder, lettuce, cherry, kiwifruits, walnut, schisandra wine, and milk; Barley grass powder with higher GABA and calcium, as well as potassium. However, the sleep duration for modern humans is associated with food structure of ancient humans.

Tryptophan can increase the production of niacin, serotonin and melatonin. Tryptophan is not only a precursor of the neurotransmitter serotonin and the neurosecretory hormone melatonin for sleep/wake but it is also metabolized in the brain along different pathways to serotonin, melatonin and niacin and is partly used as a source of protein synthesis. The dietary tryptophan through the blood-brain barrier is favored by competing large neutral amino acids and carbohydrates; 5-hydroxytryptophan is converted to serotonin by aromatic L-amino acid decarboxylase and pyridoxine, however, serotonin is converted to melatonin by arylalkylamine-N-acetyltransferase and n-3 fatty acids.

The study by Milagres MP et. al 'Night milking adds value to cow's milk' in 2014 aimed to evaluate the melatonin concentration in milk collected by milking during the night and evaluating its effect, with or without tryptophan supplementation was done to measure the sleep quality of adult Wistar rats. The conclusion of the study was "Combining the techniques of night milking with tryptophan supplementation resulted in production of milk that improves sleep quality in rats."

While interesting, most of the answer is irrelevant to the question. The only relevant point is the statement "The research whether the best time to drink milk is at night is inconclusive since human trials for this are not yet performed." which needs a reference. –  Sklivvz Jul 10 at 13:26
The answer provides evidence that milk is a functional food promoting sleep. In the absence of research evidence for the question 'whether the best time to drink milk is at night', it's imperative to assume that the timing of drinking milk in humans is not yet scientifically researched or the effects reported for publishing. The answer also talks about the action of Tryptophan in promoting sleep which is mentioned in the attached paper. The question talks about night milking research which until now is done in only adult Wistar rats for sleep quality which is mentioned in the answer. –  pericles316 Jul 11 at 7:34
You still need to reference the absence of research. How did you get to such a conclusion? –  Sklivvz Jul 11 at 7:37
@pericles316: "The absence of published research" - this is begging the question. What makes you say there is an absence of research. Can you quote an expert making such a claim? –  Oddthinking Jul 11 at 7:43
I don't find it very relevant to the OP question, but that's not my major concern. The concern is that you are answering the question ("inconclusive") without reference. As it stands, it's simply your opinion. –  Sklivvz Jul 11 at 7:47
