10 Proven Health Benefits of Almonds

Almonds are a rich source of nutrients like vitamins, minerals, and healthy fatty acids. 

It does not require much preparation to be included in the daily diet. It has found its prominent place in snacks, cakes, meals, and many other food recipes.

From reducing the wrinkles in the skin to its provisions for a healthy heart, almonds are popular around the world.

1. Rich Source of Vitamin E 

Almonds are an abundant source of vitamin E. An ounce of almonds has 7.3 mg of vitamin E. 100 grams of almonds can offer you 171% of your daily vitamin E requirements.

The vitamin E found in almonds have a positive impact on the levels of cognition among the elderly.

A study that had a follow-up period of over 3 years and 2 months noted that there was a 36% reduction in the rate of decline among subjects with the highest vitamin E consumption as compared with those who had the lowest (1). Cognitive decline reduced noticeably with a higher intake of vitamin E.

Summary: The consumption of vitamin E through foods or supplements is connected with the reduction in cognitive decline. Vitamin E can influence cognition even among the aged group of people.

2. Almonds have Antioxidant properties

The vitamin E in almonds is known to have potent antioxidant properties. These antioxidants protect your cells from oxidative damage, thus slowing down aging and reducing the risk of diseases such as heart disease and cancer.

Almonds have been found to help lower the levels of biomarkers associated with smoking. A 2007 study, using 60 men (18 to 25 years) who smoked 5 to 20 cigarettes a day, noted that intake of almonds decreased oxidative stress pathways among men who smoked. (2) They were given 84 grams of almonds per day for 4 weeks.

Summary: The supplementation of almonds works as a defence and reduces biomarkers of oxidative stress in smokers.

3.  The Effect of Almonds on Cardiovascular Diseases

Did you know that eating almonds not only reduces your bad cholesterol levels, it also increases your response to insulin, thus helping regulate your blood glucose levels?

A study conducted in 2010 evaluated whether including almonds in the diet improved insulin responsiveness and other cardiovascular risk factors among adults who had prediabetes, in comparison to a diet that is almond free (3).

The participants who were given 2 ounces of almonds per day, in the 16-week trial period, showed a decline in insulin resistance and beta-cell function when compared to the nut-free control group.

A significant decline in LDL(bad cholesterol) was also observed in the almond-diet group.

Summary: A diet rich in almonds improves insulin sensitivity in prediabetic people. LDL levels also show a noteworthy decline with almond intake.

4. Appetite Control With Almonds

Snacking forms a major portion of our daily food intake. Almonds are a nutrient-rich and satiating natural food.

A 2013 study examined the effects of almonds as a common snack food item (4). They investigated the influence of almonds on blood glucose after snacking, appetite, short-term body weight, and fasting blood parameters when taken with meals or as a separate snack.

137 participants, with a high risk of type 2 diabetes, took 43 grams of almonds a day, as a morning or afternoon snack or with their meal.

It was noted that their blood glucose levels were lower in postprandial tests compared to those who did not have almonds as snacks. These people also reported reduced levels of hunger and food cravings.

Summary: The study concluded that almonds serve post-ingestive metabolic appetite benefits. The almond snacking did not raise the risk of weight gain. The study indicates that almond snacking is a healthy dietary option.

5. Weight Loss Benefit of Almonds

An experiment was taken up to assess the effects of a high almond (high monounsaturated fat, MUFA) or complex carbs (high carbohydrate) low-calorie diet on anthropometric body compositions and metabolic paraments in a weight reduction initiative. (5)

The experiment lasted for 24 weeks. 65 adults between the ages of 27 to 79 years with a body mass index (BMI) of 27-55 kg/m2 were involved in the experiment. The supplementation was of 84 grams to be taken every day (almond-low calorie diet that had 39% total fat, 25% MUFA and 32% carbs as a percent of dietary energy) or self-selected carbs that had equal calories and protein.

Various anthropometric measurements, body composition and metabolic parameters before, during and after 24 weeks of the dietary supplementation were taken.

There was a significant reduction in weight and BMI (62%), waist circumference (50%), fat mass (56%), total body water and systolic blood pressure in the almond low-calorie diet (LCD) group.

High-density lipoprotein cholesterol increased in the high carb LCD group and decreased in the almond-LCD group. Glucose, insulin, diastolic blood pressure, total cholesterol triglycerides, LDL-cholesterol and the ratio of LDL-C to HDL-C reduced appreciably in both dietary trials.

It was also noted that the ketone (energy that is produced by the liver when the body has insufficient insulin to convert sugar/glucose from food to energy)  levels increased in the almond group.

Over time it was noticed that the homeostasis model analysis of insulin resistance reduced in both the study groups. Those who had type 2 diabetes, medication for the condition was constant or reduced in higher proportion in the almond group compared to the carb group participants.

Both the tests demonstrated that dietary interventions were effective in reducing body weight much further to the weight loss achieved through medical treatment.

Summary: The almond group had a consistent weight-reducing effect in the 24-week trial. The supplementation of almonds with a formula based low-calorie diet is an unconventional potential method to decrease the health implications of obesity.

6. Almond Influences Gut Health

Almonds have been found to benefit the health of the gut. A 2019 published article in ‘Current Development in Nutrition’ published the details of a trial held with the participation of college students who were assigned to snacks of almonds or graham crackers. (6)

The 8 weeks trail had 73 college freshmen. 41 women and 32 men in the age group of 18 to 19 years with a BMI of 18-41kg/m2 with no cardiometabolic disorders were selected. 38 of them were given 56.7 grams of almonds to be consumed every day that had 364-kilo calories while 35 volunteers consumed 77.5 grams per day of graham crackers that had 338 kilocalories.

Stool samples collected before and after 8 weeks of supplementation to evaluate the main microbiome outcomes. It was observed that the almond group had a decline in the amounts of a pathogenic bacterium. There was a 3% higher quantitative microbial diversity in the almond group.

Summary: The study indicated that there was an improved microbial diversity due to the almond snacking. A pathogenic bacterium significantly reduced. The composition and diversity of gut microbiome were enhanced by the morning snacking of college freshmen who were known to skip breakfast.

7. Nuts May Prevent Gallstone Formation

Medical leaders in gallstone research at Harvard Medical School brought into focus the effects of eating habits in the formation of gallstones. They came up with studies having searched the large scale Health Professional Follow-up and the Nurses Health Study.

The extra bile made by the liver is held in the gallbladder. If it has high cholesterol it would crystallize and create gallstones. A study was published in late 2004 that showed that the consumption of nuts (approximately 5 ounces a week) lowered the risk of gallstones by 30% when compared to low consumption (less than one ounce per month). (7)

This information was picked up for the Health Professionals Follow-up Study. It had 51, 529 male American dentists, optometrists, osteopathic physicians, podiatrists, and veterinarians.

The unsaturated fats in nuts keep the low-density lipoprotein cholesterol in check and reduce the total cholesterol amounts in the bile. Nuts have lots of fiber just like plants. It may prevent gallstone formation by decreasing the re-circulation of acids in the bile in the intestine. Magnesium may also have a contributory role. 

Summary: Almonds showed that it not only reduced cholesterol in the bile but also prevented the formation of gallstones. Almonds contain magnesium that supports this benefit.

8. Almonds Are Good For The Skin

Good fats as contained in almonds are beneficial for skin health. They are rich in antioxidants too. A randomized study in 2019 was done with the objective to examine the effects of almond intake on facial sebum (light yellow oily secretion of the sebaceous gland in the skin, protecting it from external factors) production and wrinkles. (8)

The participants were healthy postmenopausal women who undertook the 16-week study during which they had to consume 20% of their daily energy requirements from almonds or a calorie-matching snack. Facial photographs and image analysis systems were used to acquire standardized snaps and information on the width of wrinkles and their severity.

These measurements were noted at 0, 8 and 16 weeks. Measurements of transepidermal loss of water and sebum production were also noted in those weeks.

31 participants had taken up the trial and 28 completed it. It was observed that the almond group of women had reduced wrinkle severity and width compared to the control group. There was no adverse effect on the intake of the supplements.

Summary: The study showed a positive outcome for the daily intake of almonds. The measurements of wrinkles had reduced and it can be safely said that almonds deliver anti-aging benefits.

9. Almonds May Reduce The Risk Of Pancreatic Cancer 

A study that involved 75, 680 women in the Nurses’ Health Study investigated the association of nut consumption and pancreatic cancer in women. None of the women who participated had a history of cancer. The consumption was measured before and recorded every 2 to 4 years. (9)

There were 466 pancreatic cases. After the adjustment of age, smoking status, height, physical activity, and total energy intake it was observed that women who took one ounce or 28 grams of nuts more than 2 or equal to 2 times a week had a significantly lower risk of pancreatic cancer as compared to those who did not take nuts during the same period.

This association of a nut diet continued with strata defined by body mass index, physical activity, red meat consumption, vegetables and fruits, and smoking status.

Summary: Repeated nut consumption is inversely related to the risk of pancreatic cancer. This study did not take into consideration other factors that cause the disease. More research and study are required to standardize and optimize this health benefit.

10. Daily Intake Of Almonds And Dietary Health

A study evaluated the long-term supplementation of almonds in 43 healthy men and healthy women for a period of 6 months. This study was noted in the British Journal of Nutrition. They were between the ages of 25 to 70 years. (10)

All the participants were followed-up for a period of one year. In the first six months, they followed their own diets and in the second 6 months, the subjects added almonds to their diets. Seven random 24-hour telephone diet recalls were undertaken for each diet period. On average, the almond supplementation was 52 grams each day.

They were not given any other instructions. By the end of the study period, many beneficial changes were noted to have naturally occurred due to the intake of almonds.

The healthy fats which are monounsaturated and polyunsaturated fats increased by 42 and 24 percent. Fiber, vegetable protein, and vitamin increased by 12, 19 and 66% while copper and magnesium significantly increased by 15 and 23%.

It was further observed that trans fat intake, animal protein had notably reduced by 14 and 9 percent. Sodium, cholesterol, and sugars decreased by 21, 17 and 13%. These sets of changes were similar to dietary recommendations known to prevent cardiovascular and other long-term diseases.

Summary: The intake of almonds proved to have increased all the beneficial compounds in the body and reduced the amounts of those compounds that do not have good health provisions.

The Side Effects Of Almonds

Small quantities of almonds do not pose any side effects. However, overeating this nutritious nut create mild to moderate gastrointestinal problems. Allergies to almonds can be more dangerous, so practice caution when trying out the first time.

Nausea, diarrhea, constipation, and abdominal pain are some of the side effects associated with almond overeating. You will gain weight if you do not rpractice moderation.

About 10 to 15 almonds a day are ideal to experience the benefits without worrying about side effects.
