Triglycerides are a type of fat found in your blood.
After you eat, your body converts the calories that you don't need into triglycerides and stores them in your fat cells to be used for energy later.
While you do need triglycerides to supply your body with energy, having too many triglycerides in your blood can increase your risk of heart disease (1).
About 25% of adults in the US have elevated blood triglycerides, which is classified as having levels over 200 mg/dL (2.26 mmol/L). Obesity, uncontrolled diabetes, regular alcohol use and a high-calorie diet can all contribute to high blood triglyceride levels.
This article explores 13 ways to naturally reduce your blood triglycerides.
Whenever you eat more calories than you need, your body turns those calories into triglycerides and stores them in fat cells.
That's why losing weight is an effective way to lower your blood triglyceride levels.
In fact, research has shown that losing even a modest 5–10% of your body weight can decrease blood triglycerides by 40 mg/dL (0.45 mmol/L) (2).
While the goal is to sustain weight loss in the long term, studies have found that weight loss can have a lasting effect on blood triglyceride levels, even if you regain some of the weight.
One study focused on participants who had dropped out of a weight management program. Even though they had regained the weight they had lost nine months before, their blood triglyceride levels remained 24–26% lower (3).
Summary: Losing at least 5% of your body weight has been shown to have a lasting effect on reducing blood triglyceride levels.
Added sugar is a big part of many people's diets.
While the American Heart Association recommends consuming no more than 6–9 teaspoons of added sugar per day, in 2008 the average American was eating about 19 teaspoons daily (4).
Hidden sugar commonly lurks in sweets, soft drinks and fruit juice.
Extra sugar in your diet is turned into triglycerides, which can lead to an increase in blood triglyceride levels, along with other heart disease risk factors.
One 15-year study showed that those who consumed at least 25% of calories from sugar were twice as likely to die from heart disease as those who consumed less than 10% of calories from sugar (5).
Another study found that consuming added sugar is associated with higher blood triglyceride levels in children (6).
Even replacing sugar-sweetened beverages with water could decrease triglycerides by almost 29 mg/dL (0.33 mmol/L) (10).
Summary: Minimizing added sugar in your diet from soda, juice and sweets can reduce blood triglyceride levels.
Much like added sugar, extra carbs in your diet are converted into triglycerides and stored in fat cells.
Not surprisingly, low-carb diets have been linked to lower blood triglyceride levels.
One 2006 study looked at how various carb intakes affected triglycerides.
Those who were given a low-carb diet providing about 26% of calories from carbs had greater drops in blood triglyceride levels than those given higher-carb diets providing up to 54% of calories from carbs (8).
Another study looked at the effects of low and high-carb diets over a one-year period. Not only did the low-carb group lose more weight, but they also had greater reductions in blood triglycerides (7).
Finally, a 2003 study compared low-fat and low-carb diets. After six months, researchers found that blood triglycerides had dropped 38 mg/dL (0.43 mmol/L) in the low-carb group and only 7 mg/dL (0.08 mmol/L) in the low-fat group (9).
Summary: Following a low-carb diet can lead to a significant reduction in blood triglyceride levels, especially when compared to a low-fat diet.
Fiber is found in fruits, vegetables and whole grains.
Other good sources of fiber include nuts, cereals and legumes.
In one study, researchers showed that supplementing with rice bran fiber decreased blood triglycerides by 7–8% among people with diabetes (12).
Another study looked at how high and low-fiber diets affected blood triglyceride levels. The low-fiber diet caused triglycerides to jump 45% in just six days, but during the high-fiber phase, triglycerides dipped back below baseline levels (13).
Summary: Adding fiber to your diet from fruits, vegetables and whole grains can reduce blood triglycerides.
"Good" HDL cholesterol has an inverse relationship with blood triglycerides, meaning that high levels of HDL cholesterol can help lower triglycerides.
Aerobic exercise can increase levels of HDL cholesterol in your blood, which can then lower blood triglycerides.
When paired with weight loss, studies show that aerobic exercise is especially effective at decreasing triglycerides (14).
Examples of aerobic exercise include walking, jogging, bicycling and swimming.
Regarding amount, the American Heart Association recommends getting at least 30 minutes of exercise five days per week.
The benefits of exercise on triglycerides are most apparent in long-term exercise regimens. One study showed that jogging for two hours per week over four months led to a significant decline in blood triglycerides (15).
Other research has found that exercising at a higher intensity for a shorter amount of time is more effective than exercising at a moderate intensity for longer (16).
Summary: A regular workout regimen with high-intensity aerobic exercise can increase "good" HDL cholesterol and decrease blood triglycerides.
Artificial trans fats are a type of fat added to processed foods to increase their shelf life.
Trans fats are commonly found in commercially fried foods and baked goods made with partially hydrogenated oils.
Eating trans fats can also increase your blood triglyceride levels.
One study showed that triglyceride levels were significantly higher when participants followed a diet with high or moderate amounts of trans fats, compared to a diet high in unsaturated oleic acid (20).
Another study found similar results. Following a three-week diet high in trans fats resulted in higher triglyceride levels than a diet high in unsaturated fat (21).
Summary: A diet high in trans fats can increase both blood triglycerides and the risk of heart disease. Limit your consumption of processed, baked and fried foods to minimize your trans fat intake.
Fatty fish is well known for its benefits on heart health and ability to lower blood triglycerides.
This is mostly due to its content of omega-3 fatty acids, a type of polyunsaturated fatty acid that is considered essential, meaning you need to get it through your diet.
Both the Dietary Guidelines for Americans and American Heart Association recommend eating two servings of fatty fish per week.
In fact, doing so can decrease the risk of death from heart disease by 36% (22).
A 2016 study showed that eating salmon twice a week significantly decreased blood triglyceride concentrations (23).
Salmon, herring, sardines, tuna and mackerel are a few types of fish that are especially high in omega-3 fatty acids.
Summary: Fatty fish is high in omega-3 fatty acids. Eating two servings per week can decrease the risk of heart disease and reduce triglyceride levels.
Studies show that monounsaturated and polyunsaturated fats can reduce blood triglyceride levels, especially when they are replacing other types of fat.
Monounsaturated fats are found in foods like olive oil, nuts and avocados. Polyunsaturated fats are present in vegetable oils and fatty fish.
One study analyzed what 452 adults had eaten over the past 24 hours, focusing on several types of saturated and polyunsaturated fats.
Researchers found that saturated fat intake was associated with increased blood triglycerides, while polyunsaturated fat intake was associated with lower blood triglycerides (24).
Another study gave elderly participants four tablespoons of extra virgin olive oil daily for six weeks. For the duration of the study, this was the only source of added fat in their diets.
The results showed a significant decline in triglyceride levels, as well as total cholesterol and LDL cholesterol levels, compared to the control group (25).
To maximize the triglyceride-lowering benefits of unsaturated fats, pick a healthy fat like olive oil and use it to replace other types of fat in your diet, such as trans fats or highly processed vegetable oils (21).
Summary: Monounsaturated and polyunsaturated fats can decrease blood triglyceride levels, especially when they are consumed in place of other fats.
Insulin resistance is another factor that can cause high blood triglycerides.
After you eat a meal, the cells in your pancreas send a signal to release insulin into the bloodstream. Insulin is then responsible for transporting glucose to your cells to be used for energy.
If you have too much insulin in your blood, your body can become resistant to it, making it difficult for insulin to be used effectively. This can lead to a build-up of both glucose and triglycerides in the blood.
Fortunately, setting a regular eating pattern can help prevent insulin resistance and high triglycerides.
However, the evidence is mixed when it comes to meal frequency.
A 2013 study demonstrated that eating three meals per day significantly decreased triglycerides, compared to eating six meals per day (28).
On the other hand, another study showed that eating six meals per day led to a greater increase in insulin sensitivity than eating three meals per day (29).
Regardless of how many meals you're eating daily, eating regularly can improve insulin sensitivity and lower blood triglyceride levels.
Summary: While research is unclear on how meal frequency affects blood triglyceride levels, studies show that setting a regular meal pattern can decrease many heart disease risk factors and prevent insulin resistance.
Alcohol is high in sugar and calories.
If these calories remain unused, they can be converted into triglycerides and stored in fat cells.
Although a variety of factors come into play, some studies show that moderate alcohol consumption can increase blood triglycerides by up to 53%, even if your triglyceride levels are normal to begin with (30).
Summary: Some studies suggest that limiting your alcohol intake can help lower blood triglyceride levels.
Particularly, soy protein has been shown to reduce blood triglyceride levels.
A 2004 study compared how soy and animal proteins affected triglycerides. After six weeks, soy protein was found to decrease triglyceride levels by 12.4% more than animal protein (37).
Similarly, an analysis of 23 studies found that soy protein was associated with a 7.3% decline in triglycerides (38).
Soy protein can be found in foods like soybeans, tofu, edamame and soy milk.
Summary: Soy contains compounds associated with several health benefits. Eating soy protein in place of animal protein can reduce blood triglycerides.
Tree nuts provide a concentrated dose of fiber, omega-3 fatty acids and unsaturated fats, all of which work together to lower blood triglycerides.
One analysis of 61 studies showed that each serving of tree nuts decreased triglycerides by 2.2 mg/dL (0.02 mmol/L) (39).
Another analysis including 2,226 participants had similar findings, showing that eating tree nuts is associated with a modest decrease in blood triglycerides (40).
Tree nuts include:
- Brazil nuts
- Macadamia nuts
Keep in mind that nuts are high in calories. A single serving of almonds, or about 23 almonds, contains 163 calories, so moderation is key.
Summary: Nuts contain many heart-healthy nutrients, including fiber, omega-3 fatty acids and unsaturated fats. Studies suggest that eating between 3–7 servings of tree nuts per week can decrease blood triglycerides.
Several natural supplements could have the potential to lower blood triglycerides.
Below are a few of the main supplements that have been studied:
- Fish oil: Well known for its potent effects on heart health, one study found that taking fish oil supplements reduced triglycerides by 48% (44).
- Fenugreek: Though traditionally used to stimulate milk production, fenugreek seeds have also been shown to be effective at reducing blood triglycerides (45).
- Garlic extract: Several animal studies have shown that garlic extract can reduce triglyceride levels, thanks to its anti-inflammatory properties (46, 47, 48).
- Guggul: This herbal supplement has shown promise in decreasing triglyceride levels when used with nutrition therapy in patients with high cholesterol (49).
- Curcumin: A 2012 study found that supplementing with a low dose of curcumin can cause a significant drop in blood triglycerides (50).
Summary: Several supplements have been studied for their ability to lower triglyceride levels, including fish oil, fenugreek, garlic extract, guggul and curcumin.
