For most young, healthy adults, caffeine doesn't appear to noticeably affect blood sugar (glucose) levels, and having up to 400 milligrams a day appears to be safe.
Caffeine raises levels of certain stress hormones, like epinephrine (also called adrenaline). Epinephrine can prevent your cells from processing as much sugar. It may also keep your body from making as much insulin. It blocks a protein called adenosine.
Plain coffee does not seem to directly increase levels of blood sugar, or blood glucose. This is good news for people with diabetes who like black coffee. However, some research suggests that the caffeine in coffee could impair insulin sensitivity, which is not ideal for people with diabetes.
Barley or jau water is high in insoluble fibre, which makes it good for diabetics. It is recommended for diabetics as it helps stabilise blood glucose levels. Make sure you drink unsweetened barley water to get effective results. The antioxidant properties of barley water also helps keep many diseases at bay.
Drinking water regularly may rehydrate the blood, lower blood sugar levels, and reduce diabetes risk ( 20 , 21 ). Keep in mind that water and other zero-calorie drinks are best. Avoid sugar-sweetened options, as these can raise blood glucose, drive weight gain, and increase diabetes risk ( 22 , 23 ).
A: Drinking apple cider vinegar at bedtime can help diabetic people control their blood glucose levels. A diabetic patient should take one teaspoon of apple cider vinegar in warm water before sleep. It can also aid in the regulation of fasting blood sugar levels in the morning.
Our data suggest that individuals who ingest moderate amounts of caffeine may develop hypoglycemic symptoms if plasma glucose levels fall into the "low-normal" range, as might occur in the late postprandial period after ingestion of a large carbohydrate load.
"Put simply, our blood sugar control is impaired when the first thing our bodies come into contact with is coffee especially after a night of disrupted sleep. We might improve this by eating first and then drinking coffee later if we feel we still feel the need it.
Blood sugar below 55 mg/dL is considered severely low.
Treatment—The "15-15 Rule"
The 15-15 rule—have 15 grams of carbohydrate to raise your blood glucose and check it after 15 minutes. If it's still below 70 mg/dL, have another serving. Repeat these steps until your blood glucose is at least 70 mg/dL.
If a person experiencing hypoglycemia becomes unconscious, a person should call 911. Then they should turn the affected person on their side and deliver a glucagon shot. According to the ADA, the person should come around within 15 minutes. They will need immediate medical attention if they do not.
Indeed, according to experts, drinking coffee on an empty stomach right after waking up can interfere with your cortisol levels and actually leave you feeling even more tired later on in the day.
Morning brew found to impair blood sugar response by 50 per cent when consumed on empty stomach.

The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia. It usually happens between 4 a.m. and 8 a.m.
What should your blood sugar be when you wake up? Whenever possible, aim to keep your glucose levels in range between 70 and 130 mg/dL in the morning before you eat breakfast, and between 70 and 180 mg/dL at other times.

By delaying his caffeine 90 minutes to 2 hours after waking, Huberman wards off a late afternoon, or even early afternoon, crash after the caffeine wears off. And the delay allows for cortisol to follow its regular pattern.
Hu said that moderate coffee intake—about 2–5 cups a day—is linked to a lower likelihood of type 2 diabetes, heart disease, liver and endometrial cancers, Parkinson's disease, and depression. It's even possible that people who drink coffee can reduce their risk of early death.
“Have coffee when the body is producing less cortisol, about three to four hours after waking,” Cipullo says. In other words, if you wake up between 6. a.m. and 8 a.m, have your coffee between 9 a.m. and 11 a.m.
