Cholesterol is a waxy substance the body uses to make cells and hormones. High-density lipoprotein (HDL) and low-density lipoprotein (LDL) are two different kinds of cholesterol.
LDL can be a “bad” type of cholesterol because it can accumulate on the inner lining of blood vessels, forming plaque. As plaque progresses, it can narrow blood vessels, reducing how much blood the vessels can carry. Plaque buildup is especially dangerous when it forms in arteries supplying vital organs such as the brain or heart. Narrowed arteries also increase the risk of a blood clot or other substances becoming stuck in them. This can increase the risk of heart attack and stroke.
HDL can be a “good” type
of cholesterol. It absorbs circulating cholesterol and returns it to the liver
for excretion.
To stay healthful, most
people need to limit or reduce their levels of LDL and increase their HDL
levels. This helps ensure they have enough HDL circulating to keep LDL levels
in check.
Many different types of
drinks contain compounds that may help reduce cholesterol levels or healthfully
maintain them. These include:
1. Green tea
Green tea contains
catechins and other antioxidant compounds that seem to help lower “bad” LDL and
total cholesterol levels.
Black tea can also have
a positive impact on cholesterol, but to a lesser extent than its green
variant. This is mainly because different amounts of catechins in the teas mean
that the body absorbs liquid differently.
Additionally, caffeine
can also help raise HDL levels.
2. Soy milk
Soy is low in saturated
fat. Replacing cream or high fat milk products with soy milk or creamers may
help reduce or manage cholesterol levels.
The Food and Drug
Administration (FDA) recommend consuming 25 grams (g) per day of soy protein as
part of a diet low in saturated fat and cholesterol to help reduce the risk of
heart disease.
3. Oat drinks
Oats contain
beta-glucans, which create a gel-like substance in the gut and interact with
bile salts, reducing cholesterol absorption.
For maximum benefit, try
consuming around 3 g per day of beta-glucans, which can lead to a 7% reduction
in LDL. One cup of oat milk can provide up to 1.3 g of beta-glucans.
4. Tomato juice
Tomatoes are rich in a
compound called lycopene, which may improve lipid levels and reduce “bad” LDL
cholesterol. Research suggests processing tomatoes into juice increases
their lycopene content.
Tomato juice is also
rich in cholesterol-reducing fiber and niacin.
5. Berry smoothies
Many berries are rich in
antioxidants and fiber, both of which may help reduce cholesterol levels.
In particular,
anthocyanins, a powerful antioxidant agent in berries, can help improve
cholesterol levels.
6. Drinks containing
sterols and stanols
Sterols and stanols are
plant chemicals similar in shape and size to cholesterol that block the
absorption of some cholesterol. And so some companies are adding these
chemicals to several foods and drinks, including fortified yogurt drinks, milk
and fruit juices to achieve this purpose.
7. Cocoa drinks
Cocoa is the main
ingredient in dark chocolate. It contains antioxidants called flavanols that
may improve cholesterol levels.
Cocoa also contains high
levels of monounsaturated fatty acids, which can also help improve cholesterol
levels.
8. Alcohol
Some research has found
that low-to-moderate alcohol consumption, depending on age and sex, could be more
beneficial in terms of heart health than not drinking at all.
Moderate alcohol
consumption seems to increase “good” HDL cholesterol levels. Moderate
consumption involves drinking up to 1 alcoholic drink per day for females and
up to 2 for males.
However, heavy drinking
increases cholesterol, and consuming alcohol carries so many health risks that
its negative effects may outweigh its benefits.
In addition, some behavioral changes or habits can help lower cholesterol levels such as getting at least 2 hours and 30 minutes of moderate-to-intense exercise per week, eating healthful foods and quitting smoking.
