Given that cardiovascular disease (CVD) is a leading cause of death worldwide, the risk reduction provided by garlic’s nutritional and phytochemical components is significant. Through the synergistic effects of these components, garlic can substantially decrease the risk of conditions like atherosclerosis, hypertension, diabetes, hyperlipidemia, myocardial infarction, and ischemic stroke.
Furthermore, garlic has shown potential as an antimicrobial agent, with evidence suggesting its efficacy against pathogenic viruses, bacteria, yeast, and fungi.
It is, however, crucial to keep in mind that garlic can interact with certain medications, and consuming excessive amounts of raw garlic may lead to undesirable side effects, such as bad breath, heartburn, and stomach issues. Therefore, it is generally advised to limit consumption to 1-2 garlic cloves daily.
Consumption of Raw Garlic
Eating raw garlic may provide additional health benefits as compared to cooked garlic because some beneficial compounds in garlic, such as allicin, are sensitive to heat. Therefore, consuming garlic raw can help maintain these compounds. Despite this, there is a common belief that consuming garlic on an empty stomach may improve its health benefits. However, more research is needed to establish whether this claim holds any weight.
There are no official recommendations for the dosage of garlic. Nonetheless, most studies suggest that consuming around 1-2 cloves per day could be beneficial. In supplement form, doses of up to 3,600 mg of aged garlic extract have been shown to be effective. It is important to consult your doctor before using garlic supplements, especially if you have any underlying health conditions or are on medications.
Certain studies have indicated that regular consumption of raw garlic may help with conditions such as chronic hepatitis and nonalcoholic fatty liver disease (NAFLD). In patients with NAFLD, garlic powder consumption has been shown to reduce body weight and fat mass.
In addition to eating raw or cooked, garlic can also be taken as a supplement. This can serve as an alternative method of consumption for those who may not prefer the taste of raw or cooked garlic.
