Knowing these different levels helps each person to make their decision. What is known is that the health risks related to alcohol consumption over the lifetime increase with the quantity consumed... There isn't a clear level of consumption that allows one to definitively health risks over their lifetime. Nonetheless, experts of Public Health France and the National Cancer Institute attempted to define acceptable risks and proposed a single value for both sexes, expressed in standard drinks.

10 Low-risk is not no-risk. Even when drinking within low-risk limits, a range of factors can affect your level of risk, including the rate of drinking, your body type or genetic makeup, your gender, existing health problems and if you are young or an older person. There are times and circumstances when you should not drink alcohol. It's advisable not to drink if you: are pregnant or planning to get pregnant; are on medication that interacts with alcohol; have a condition made worse by drinking alcohol; feel unwell, depressed, tired or cold as alcohol could make things worse; are about to operate machinery or a vehicle or do anything that is risky or requires skill. 
For children and young people under 18 years, not drinking alcohol is the safest option. Those under 15 years of age are at the greatest risk of harm from drinking alcohol and not drinking in this age group is especially important. 
For young people aged 15 to 17 years, the safest option is to delay drinking for as long as possible. If 15 to 17 year olds do drink alcohol, they should be supervised, drink infrequently and at levels usually below and never exceeding the adult daily limits.

Avoid consuming alcoholic beverages. Be informed about the effects of excessive alcohol consumption. Avoid making alcohol an essential part of family and social gatherings. If you consume alcohol, do so in moderation, with friends and people you trust.

Wine can be beneficial for health, but it is harmful when consumed quickly and in large quantities. Do not drink on an empty stomach, eat something while drinking alcohol. If you are taking medications, do not drink alcohol. Alcohol can intensify the effect of many medicines and can interact with others, making them ineffective or dangerous.
Philippines Food and Nutrition Research Institute, Nutritional Guidelines for Filipinos (2012) 
Myths and truths about alcohol (2008)
24 g/day 12 g/day 12 Nutritional Guidelines (2012): Limit alcohol drinking to one drink per day for women and two drinks for men is also advised. One alcoholic drink is equivalent to one and half ounce distilled beverage such as gin or 12 ounces or a bottle of beer or four ounces wine or half glass wine or an ounce of 100 proof whiskey.

Myths and Truths (2008): Authorities have defined moderation as not more than two drinks a day for the average-sized man, and not more than one drink a day for the average-sized woman. But, still the exact amount of moderate alcohol intake per day cannot be defined because people have different tolerances to alcohol. Thus, the amount a person can drink safely is highly individualized, depending on genetics, health conditions, sex, weight, age, and family history. In addition, the liver can process about half ounce ethanol per hour (the amount in a typical drink), depending on the person's body size, previous drinking experience, food intake, and general health.

Romania Ministry of Health, Healthy Eating Guidelines 2006 32-40 g/day 15-20 g/day [none] Rule 8 (of 9) for healthy eating: Consume alcohol in moderation or not at all. While modest quantities of alcohol are not detrimental to most people and can even have beneficial effects in certain circumstances, regular consumption of excessive amounts carries substantial risks.
Russia National Medical Research Center for Preventive Medicine of the Ministry of Healthcare, prevention information materials (2019) 20 g/day 30 g/day 10 Abstain for two days a week. These limits dscribe low-risk drinking in quantitaitve terms. Alcohol consumption of even these seemingly low portions can lead to problems if the drinking takes place at the wrong time or in the wrong place. This concept applies not only to the amount of alcohol consumed, but mainly to where and when it happens and how it affects the behavior of the drinker and others. In addition, there are situations when any use of alcohol is extremely undesirable, for example, when driving, pregnancy, etc.

United Kingdom Department of Health, UK Chief Medical Officers’ Low Risk Drinking Guidelines 2016 

National Health Service, Alcohol Misuse
up to 112 g/week up to 112 g/week 8 This applies to adults who drink regularly or frequently i.e. most weeks. The Chief Medical Officers’ guideline for both men and women is that: 
• To keep health risks from alcohol to a low level it is safest not to drink more than 14 units a week on a regular basis. 
• If you regularly drink as much as 14 units per week, it is best to spread your drinking evenly over 3 or more days. If you have one or two heavy drinking episodes a week, you increase your risks of death from long term illness and from accidents and injuries. 
• The risk of developing a range of health problems (including cancers of the mouth, throat and breast) increases the more you drink on a regular basis. 
• If you wish to cut down the amount you drink, a good way to help achieve this is to have several drink-free days each week. 
This applies to drinking on any single occasion (not regular drinking, which is covered by the
weekly guideline). The Chief Medical Officers’ advice for men and women who wish to keep their short term health risks from single occasion drinking episodes to a low level is to reduce
them by: limiting the total amount of alcohol you drink on any single occasion, drinking more slowly, drinking with food, and alternating with water, and planning ahead to avoid problems e.g. by making sure you can get home safely or that you have people you trust with you. 
The sorts of things that are more likely to happen if you do not understand and judge correctly the risks of drinking too much on a single occasion can include: accidents resulting in injury, causing death in some cases, misjudging risky situations, and losing self-control (e.g. engaging in unprotected sex). The risks of injury to a person who has been drinking recently have been found to rise between two and five times when 5-7 units (40-56 g) are drunk in a 3-6 hour period. 
Some groups of people are more likely to be affected by alcohol and should be more careful of their level of drinking on any one occasion for example those at risk of falls, those on medication that may interact with alcohol or where it may exacerbate pre-existing physical and mental health problems.
If you are a regular weekly drinker and you wish to keep both your short- and longterm health risks from drinking low, this single episode drinking advice is also relevant for you.

14 Dietary Guidelines for Americans (2015-2020):
If alcohol is consumed, it should be in moderation—up to one drink per day for women and up to two drinks per day for men—and only by adults of legal drinking age. … if alcohol is consumed, the calories from alcohol should be accounted for so that the limits on calories for other uses and total calories are not exceeded... 
High-risk drinking: 56g or more on any day or 112g/week or more for women and 70g or more on any day or 210g/week or more for men. Binge drinking: consumption within about 2 hours of 56g or more for women and 70g or more for men.
Excessive alcohol consumption: includes binge drinking, heavy drinking (112g/week or more for women and 210g/week or more for men), and any drinking by pregnant women or those under 21 years of age 
Many individuals should not consume alcohol, including individuals who are taking certain over-the-counter or prescription medications or who have certain medical conditions, those who are recovering from alcoholism or are unable to control the amount they drink, and anyone younger than age 21 years. Individuals should not drink if they are driving, planning to drive, or are participating in other activities requiring skill, coordination, and alertness. 

These guidelines are specifically for low risk of developing alcohol use disorders. 
If you have a health problem or take certain medications, you may need to drink less or not at all.

Drinking is never completely safe, but if you decide to do it, try to reduce risks as much as possible. To do so you can calculate your units and keep in mind the limits. 
Do not exceed these limits. If you are accustomed to drinking, avoid alcohol for at least two days each week. 
Children and pregnant women should not drink alcohol.
