Which is more nutritious, black sesame seeds or white sesame seeds? Calcium, iron, fatty acids, and consumption guidelines.

Black and white sesame seeds are very common "garnish ingredients" on the dining table—sprinkled on white rice to enhance the aroma, mixed into sweet and sour pork ribs and blanched vegetables to add layers of flavor, or added a touch of fragrance to desserts. However, sesame seeds themselves are actually...The nutrient density is quite high.This food contains dietary fiber, minerals, and a variety of active ingredients in just a small spoonful.

Because of its popularity, there are many claims about sesame: "Black sesame is a good source of calcium," "White sesame has a higher protein content," "One tablespoon of black sesame powder provides half of your daily calcium requirement," "The main fatty acid in sesame is linoleic acid," and so on.The direction is correct, but the numbers are exaggerated.Some areName misspelledThis article will use verifiable data to compare black sesame seeds with white sesame seeds.item by itemAnd examine each of the common sayings circulating in the public.

First, let's clarify the scope: This article only discusses the role of black and white sesame seeds in a balanced diet.Nutritional differences and ways of eating，This does not constitute advice for the diagnosis, treatment, or prevention of any disease.If you have a history of chronic illness or allergies, please follow the advice of your doctor and registered dietitian.

Are black sesame and white sesame the same plant?

Let's first clarify a fundamental point that is often overlooked:Black sesame and white sesame are actually the same plant.Sesamum indicum Different varieties of L. (Pedalaceae family)The main difference lies in the color and composition of the seed coat, not in the two different plants. Sesame seeds, flax seeds, chia seeds, etc., are all "seeds," not woody nuts—this is especially important for people with allergies (see "What to Note When Eating" below).

但The same plant, sold in different forms, can have vastly different nutritional profiles.This is the key to understanding black and white sesame seeds:

• Black sesamegenerallyWhole seeds with seed coat (with shell) soldThe seed coat is the main concentration of calcium, iron, dietary fiber, and antioxidants.
• White sesame seedsMost commercially available areShelled kernels(decorticated) The seed coat is worn away, resulting in a significant decrease in mineral content.

In other words, the common saying that "black sesame seeds are better for calcium than white sesame seeds" is not based on the idea that "black is better," but rather...The difference between shelled and shelledThe data table in the next section will list the differences in detail—the difference in calcium content between the two.More than ten times。

To understand the role of sesame in the overall diet (it belongs to the "Oil & Nut & Seed" category), please refer to the information on this website.Six food groups and a balanced diet〉。

Why is sesame considered a food with high nutrient density?

The nutritional characteristics of sesame can be summarized in one sentence:Small in portion size, high in calories and fat, but also rich in minerals and active ingredients.。

• High in fat100 grams of sesame seeds in their shells contain about 49.7 grams of fat, while 100 grams of shelled sesame seeds contain about 61.2 grams. They are high in fat, so portion control is very important.
• Mainly unsaturated fatsFat is mostly composed of monounsaturated and polyunsaturated fatty acids, with saturated fat accounting for a relatively low proportion.
• Mineral concentration: sesame seeds with shells are a good source of calcium, iron, magnesium, copper, zinc and manganese; after shelling, they are mainly composed of magnesium, zinc and copper, while calcium levels drop significantly.
• Rich in dietary fiberIt contains approximately 11.8 grams (with shell) / 11.6 grams (without shell) per 100 grams, making it a high-fiber food.
• Active ingredients such as lignansSesamin, sesamolin, and sesamol are among the most studied components of sesame (see below).

A comprehensive review also indicates that sesame seeds are rich in protein and lipids, and contain lignans, an active ingredient, which has been the subject of numerous studies on antioxidant and lipid-regulating effects (Wei et al., 2022).PMID 36235731However, it needs to break even:These are mostly "research directions" rather than "established efficacy".For details, please see the Evidence section below.

Nutritional comparison of black sesame seeds and white sesame seeds (with data table)

The figures in the table below are taken from the USDA FoodData Central and are all per 100 grams. Since the database does not have separate entries for "black sesame" and "white sesame," this article uses..."Whole, dried sesame seeds (FDC ID 170150)" corresponds to regular black sesame seeds.,by"Sesame seed kernels, dried (decorated), FDC ID 169412" corresponds to regular white sesame seeds.The actual figures may vary depending on the commercially available varieties and degree of baking. This table is for informational purposes only.Relative comparisonFor use.

Nutrients (per 100 grams)	Whole seeds with shells (usually black sesame seeds)	Shelled sesame seeds (usually white sesame seeds)	Compare
calorific value	573 kcal	631 kcal	High shelling
protein	17.7 grams	20.5 grams	Approximately 151 TP4T after shelling
Fat	49.7 grams	61.2 grams	High shelling
carbohydrate	23.5 grams	11.7 grams	High shell
Dietary fiber	11.8 grams	11.6 grams	Roughly the same
鈣	975 mg	60 mg	Approximately 16 times larger with shell
鐵	14.6 mg	6.4 mg	Approximately 2.3 times larger with shell
鎂	351 mg	345 mg	Roughly the same
鋅	7.8 mg	6.7 mg	Roughly the same
銅	4.1 mg	1.4 mg	Approximately 2.9 times larger with shell.
folate	97 micrograms	115 micrograms	Shelling slightly higher
choline	25.6 mg	25.6 mg	same
Vitamin E (alpha-tocopherol)	0.25 mg	1.68 mg	High shelling
Vitamin K.	0 micrograms	0 micrograms	Both are extremely low
Saturated fat	7.0 grams	9.1 grams	High shelling
Monounsaturated fats	18.8 grams	23.9 grams	High shelling
Polyunsaturated fats	21.8 grams	25.5 grams	High shelling

Several points to pay special attention to:

• The biggest difference is in calcium.Black sesame seeds contain approximately 975 mg of calcium with the shell on, but only 60 mg without the shell, a difference of about 16 times. This is because calcium is mainly concentrated in the seed coat—black sesame seeds are mostly eaten with the shell on, while white sesame seeds are mostly peeled off. This is the true source of the calcium in black sesame seeds.
• Fat and protein are slightly better when shelled.After the husk is removed, the weight of the seed coat is reduced, and the proportion of fat and protein naturally increases. Therefore, the statement that "white sesame seeds are higher in protein and fat" is correct, but the difference is only about 10%, which cannot be described as "more prominent".
• The statement "Black sesame seeds are rich in Vitamin E" needs to be corrected.According to the USDA database, whole seeds with shells contain only about 0.25 mg of α-tocopherol, while shelled kernels contain about 1.68 mg. Looking at this alone...Neither black nor white sesame seeds are particularly outstanding sources of Vitamin E.The antioxidant component of sesame that has been truly studied is lignan (see next section).
• Vitamin K content is almost zero.Both are 0 micrograms. Therefore, people taking the blood thinner (warfarin)There's no need to specifically limit sesame seeds because of Vitamin K.—The foods you should really pay attention to for vitamin K are dark green leafy vegetables, broccoli, etc.

Examining common sayings item by item

Statement 1: "The main fatty acid in sesame seeds is linoleic acid."

This isName misspelledThis is also the most common type of confusion. The main fatty acids in sesame seeds are...Linoleic acid (an omega-6 fatty acid)It accounts for about 40% of fat;Alpha-linolenic acid (an omega-3 fatty acid)It is present in very low amounts in sesame seeds. The two words differ by only one character in Chinese, but they are completely different substances.

One more point: Linoleic acid and linolenic acidBoth are essential fatty acids for the human body.(That is, the body cannot synthesize them on its own and must obtain them from food), so the statement "essential fatty acids are important" is correct, but sesame mainly provides linoleic acid (ω-6), not alpha-linolenic acid (ω-3).If you want to supplement your omega-3 intake, flaxseed, chia seeds, walnuts, and deep-sea fish are the main sources.It's not sesame seeds.

Claim 2: "A cup of milk with a tablespoon of black sesame powder can provide 501 TP4T of calcium daily."

This numberIt was exaggerated by about five times.Let's calculate it using verifiable figures:

• 100 grams of sesame seeds in their shells contain approximately [amount missing] calcium. 975 mgThe U.S. Department of Agriculture listedOne tablespoon is approximately equal to 9 grams.。
• Therefore, one tablespoon (9 grams) of sesame seeds in their shells contains approximately [amount missing] calcium. 88 mg。
• The recommended daily calcium intake for adults (191 TP 1T 50 years old) is approximately 1,000 mg(NIH Office of Dietary Supplements, USA).
• 88 ÷ 1,000 ≈ 9%。

In other words,One tablespoon of black sesame powder provides approximately 91 TP4T of the daily calcium requirement.Not 50%. To achieve a daily intake of 50% (approximately 500 mg) solely from black sesame seeds, you would need to consume approximately... 51 grams(Approximately 5 to 6 tablespoons), while also consuming approximately 25 grams of fatThis is close to a large portion of the recommended daily fat intake for adults, which is impractical.

Furthermore, the statement "sesame seeds have extremely high calcium absorption rates" needs to be revised. Sesame seeds also contain calcium in addition to...Oxalate and phytic acidThese components will bind with calcium,Reduce the rate of calcium absorptionTherefore, although sesame seeds have a high calcium content on paper, their actual absorption efficiency is not as high as that of dairy products. Sesame seeds can be used as a source of calcium in the diet.One sourceHowever, it should not be claimed that it can replace dairy products or other sources of calcium with high absorption rates.

Claim 3: "Black sesame seeds can make hair thick and black, while white sesame seeds can nourish the lungs."

This belongs tofolk beliefsA more straightforward way to put it is:Food cannot directly "turn gray hair black" or "nourish the lungs".Hair color depends on the melanin cells in the hair follicles and genetics, and has nothing to do with the color of the food you eat. A long-term lack of nutrients such as protein, iron, and zinc may indeed affect hair health, but that is the overall effect of "balanced nutrition," not a unique effect of sesame.

It should be noted that: ifPersistent hair loss, sudden graying of hair, or accompanied by fatigue and weight changesIn cases like these, one should seek medical attention to find the cause, rather than trying to treat it by eating sesame seeds.

Claim 4: "The oil content of sesame seeds can be as high as 60%."

This numberTo look at the shapeWhole seeds with shells yield approximately 49.71 TP4T, while shelled kernels yield approximately 61.21 TP4T (USDA). Therefore, "up to 601 TP4T" does not refer to...Shelled kernelsThis is generally true; however, stating in general terms that "sesame has the highest oil content of 601 TP4T" easily leads people to underestimate its calorie content. In any case,Sesame seeds are a high-fat food, so portion control is key.。

Statement 5: "Sesame belongs to the nut category."

No. Sesame is...seedThey are not woody nuts (such as almonds, cashews, and walnuts). Nutritionally, both belong to the "Fats and Nuts/Seeds" category, but...Food allergiesFrom the perspective of sesame and woody nutsDifferent allergensPeople who are allergic to nuts are not necessarily allergic to sesame seeds, and vice versa. Therefore, this distinction is not an academic matter, but is directly related to safety.

Claim 6: "White sesame seeds are rich in zinc, which can repair cardiovascular inflammation and delay atherosclerosis."

The general direction is correct, but the conclusion needs revision. Zinc is indeed an essential trace element for the human body, and sesame seeds are a good source of zinc, magnesium, and copper (approximately 6.7 to 7.8 mg of zinc per 100 grams); however, the claim that "zinc can repair cardiovascular inflammation and delay atherosclerosis" is incorrect.OverstretchingThe focus of cardiovascular research is actually on sesame seeds.Unsaturated fats and lignansInstead of looking solely at zinc (see the evidence summary in the next section).

Claim 7: "Water-soluble nutrients are lost during the oil extraction process."

The statement is inaccurate. The truth is:Sesame oil contains only fat and fat-soluble components (such as vitamin E and phytosterols).Dietary fiber, protein, and most minerals (especially calcium) are all...It will not enter the oil.Instead, the nutrients are retained in the sesame meal after oil extraction. Therefore, relying solely on sesame oil cannot provide the most valuable calcium and dietary fiber from sesame itself—which is why this article recommends "consuming whole sesame seeds or in powder form".

Active components of sesame: lignans and sesamin

The most studied component of sesame seeds is not vitamin E, but...LignansThe main lignans in sesame include:

• Sesamin與SesamolinThe lignans unique to sesame are the core components of antioxidant and related research on sesame oil.
• SesamolIts related derivatives: mainly found in sesame oil.
• γ-TocopherolThe vitamin E components in sesame seeds are mainly gamma-tocopherol, which is different from the commonly discussed alpha-tocopherol.

Lignans are not unique to sesame seeds—flaxseeds, pumpkin seeds, soybeans, and some berries also contain lignans (Das et al., 2026).PMID 41596934A comprehensive review indicates that lignans are considered to have antioxidant activity and have been the subject of numerous studies in areas such as cardiovascular health, blood sugar, and weight management.The details of most mechanisms still require further research and confirmation.。

Another review summarized that lignan intervention studies were associated with lower total cholesterol and low-density lipoprotein cholesterol, among which...Studies on sesamin supplementation may show a link between lowering blood lipids and lowering blood pressure.However, the overall connection has not yet been established (Peterson et al., 2010).PMID 20883417）。

Sesame seeds and blood lipids/blood pressure: What research says

These are the two things that sesame seeds are most often expected to excel in. Below are some verifiable human studies, along with their limitations:

Blood lipids: There is support from a small clinical trial.

A randomized study recruited 38 patients with high cholesterol. The intervention group had a daily dietary intake of...40 grams of white sesame seedsThe intervention lasted for 60 days, during which approximately 240 kcal of energy was deducted from the diet. Results showed that the intervention group...Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and the total cholesterol/high-density lipoprotein ratio decreased significantly.Oxidative stress index (TBARS) decreased, and the activity of antioxidant enzymes (GPX, SOD) increased, whileThere was no significant change in weight or BMI.(Alipoor et al., 2012,PMID 22263599）。

Two points should be noted: First, the research uses...40 grams dailyThe amount of sesame seeds consumed was significantly higher than the average person's daily intake of 10 to 15 grams; secondly, the study also included calorie substitution, so the effect cannot be entirely attributed to sesame seeds themselves.Dietary adjustments (especially replacing saturated fats with unsaturated fats) are often more helpful for blood lipids than a single food.

Blood pressure: The meta-analysis showed a positive trend, but with high heterogeneity.

A meta-analysis of eight controlled trials involving 843 participants found that sesame intake could reduce systolic blood pressure (average -7.83 mmHg) and diastolic blood pressure (average -5.83 mmHg), but the heterogeneity among the studies was extremely high; whenOnly four trials with high methodological quality were included.At that time, the systolic blood pressure drop narrowed to approximately -3.23 mmHgThe decrease in diastolic blood pressureNot statistically significantThe authors concluded that sesame seeds may help lower blood pressure, but...Larger sample sizes and better-designed studies are still needed to confirm this.(Khosravi-Boroujeni et al., 2017)PMID 28387047）。

Compared to a recent inclusion 10 randomized controlled trials, 441 participantsThe meta-analysis also yielded similar results: sesame supplementation andDecreased systolic and diastolic blood pressureRelated to this, and improvements were observed in glycemic control indicators such as fasting blood glucose (Kuo et al., 2026,PMID 41799776）。

Balanced Summary:Sesame seeds have benefits in terms of blood lipids and blood pressure.Positive but inconsistentThe evidence from human studies is noteworthy, and the research direction is worth paying attention to. However, these studies generally have small sample sizes, high doses, and high heterogeneity.Sesame seeds cannot replace medication, nor can they replace a balanced diet and exercise.If you have high blood pressure or high cholesterol, you should still follow your doctor's instructions for follow-up appointments and medication.

How can you eat sesame seeds to maximize nutrient absorption?

Since the value of sesame mainly lies in the minerals and lignans in the seed coat,How you eat directly determines how much nutrition you can get.。

• Mainly consumed in whole grains or powder formTo obtain both calcium and dietary fiber, you should eat...Roasted sesame seeds or sesame powderInstead of just consuming sesame oil, you should consume other foods. Sesame oil only provides fat and fat-soluble components.
• Grind or chew thoroughlyWhole sesame seeds have a hard outer skin; if not chewed open, they are easily ingested whole and excreted, limiting nutrient absorption. They are suitable for people with poor teeth.Sesame powderAt home, you can use a grinder to grind roasted sesame seeds into powder.
• Black sesame seeds should be roasted until fragrant before being ground into powder.Black sesame seeds have a thicker seed coat. Roasting them before grinding them enhances their aroma and makes them easier to absorb.
• PairingAdd to milk, soy milk, cheese, or oatmeal; mix with rice, noodles, or salads; or make into sesame paste. If buying ready-made sesame paste, please note...Add sugarContent – Sugar content is often more noteworthy than sesame seeds themselves.
• If you want to supplement calcium, you should look at the combination of different foods.The calcium absorption rate of sesame seeds is not high due to the influence of oxalate and phytic acid. For daily calcium supplementation, it is still advisable to use other calcium-rich foods.Dairy products and substitutes (low-fat milk, calcium-fortified soy milk, cheese, yogurt)Sesame is the primary source, with sesame as an additional source (Centers for Health Protection <Dairy products and substitutes〉）。

How much should you eat each day? Portion sizes and calories.

Sesame seeds are rich in nutrients, butIt's a high-fat food; the key is "moderation."。

• General recommendation: approximately 10 to 15 grams daily.(Approximately 1 to 2 tablespoons of sesame powder). Some sources recommend 2 tablespoons daily as...upper limitThe understanding is quite appropriate.
• Calorie conversionBased on 573 kcal per 100 grams of whole seeds with shell, 10 grams provides approximately 57 kcal and 15 grams provides approximately 86 kcal, while also providing approximately 5 grams and 7.5 grams of fat respectively.
• To be included in daily total fatSesame seeds are classified as "oils and nuts/seeds" in nutritional terms, similar to nuts and cooking oils. If you have already eaten a lot of nuts or fried foods on the same day, you should reduce the amount of sesame seeds accordingly.
• The original manuscript's "one teaspoon" and "two tablespoons" are inconsistent.One teaspoon is about 3 grams, and one tablespoon is about 8 to 9 grams, a difference of nearly three times. This article will consistently use the phrase "about 10 to 15 grams (1 to 2 tablespoons) per day" to avoid confusion.

What precautions should be taken when consuming it?

1. Sesame allergy: The one that needs to be taken seriously the most.

Sesame isGlobally important food allergensAccording to statistics, sesame allergy affects approximately [number missing] people. North American population: 0.1%In the Middle East, it is one of the leading causes of anaphylactic shock, and in Israel, it is the third most common food allergen (Adatia et al., 2017).PMID 28490893Allergy UK also points out that sesame seeds are...It is one of the fourteen major allergens and has become one of the top ten causes of food allergies.Furthermore, sesame seeds are a "strong allergen" that can cause severe allergic reactions (anaphylactic shock).

Several key points that are easily overlooked:

• Sesame oil may still cause allergies.Unlike peanut oil, which is refined and has almost completely removed allergenic proteins, sesame oil is mostly refined...Cold-pressed, unrefinedIt retains most of its allergenic properties, so people with allergies should also avoid it.
• Many hidden sourcesSesame may be found in tahini, halvah, hummus, bread and baked goods, biscuits, noodles, dips, soups, salad dressings, sausages and processed meats, mixed spices, candy bars, etc.
• Dining out carries higher risksSesame seeds or sesame oil are often added to stir-fries, curries, risotto, etc., but this may not be listed on the menu.

The situation in Hong Kong requires special attention:The current list of legally recognized allergens under Hong Kong's Food and Drugs (Composition and Labelling) Regulation (Chapter 132W) includes gluten-containing cereals, crustaceans, eggs, fish, dairy products, peanuts, soybeans, woody nuts, and sulfites.Sesame seeds are not included.(Center for Food Safety)Read food labels to reduce the risk of food allergies> (July 2025). This meansWhen purchasing pre-packaged foods locally, it is not mandatory for the packaging to indicate the presence of sesame seeds.Those allergic to sesame should carefully read the ingredient list; if a severe allergic reaction has occurred, they should carry a doctor-prescribed adrenaline auto-injector with them and consult with an allergist.

II. Oxalate and Kidney Stones

Sesame seeds contain oxalate. For most people, the daily amount of sesame seeds is not a problem; however...People who have had calcium oxalate kidney stonesDoctors may recommend moderately controlling the intake of foods high in oxalate.The most important thing in preventing kidney stones is always to drink enough water.Instead of simply avoiding a particular food, people with a history of kidney stones should consult a doctor or nutritionist before adjusting their diet.

III. High Fat and Digestive Health

Sesame seeds are high in oil, and excessive consumption may cause bloating or discomfort in the stomach and intestines, especially...People with weak digestive function, prone to diarrhea, or suffering from irritable bowel syndromePeople with sensitive constitutions should start with small portions. From a Traditional Chinese Medicine perspective, sesame is often listed as a "laxative" food, and those with a weak constitution or prone to diarrhea should not eat too much at once—this is within the framework of Traditional Chinese Medicine theory and is for reference only.

IV. People taking medication

Sesame seeds have extremely low vitamin K content (USDA data shows close to 0 micrograms), thereforeFoods that do not require vitamin K restriction for people taking blood thinning medicationHowever, if you intend toSignificantly increase the intake of sesame seeds or sesame supplements.(For example, high-dose sesamin products) Because sesame components may affect platelets or drug metabolism, it is advisable to consult a doctor or pharmacist first and not to make significant adjustments on your own.

V. Infants and the Elderly

Whole sesame seeds pose a choking risk to young children.For children under 3 years old, it is recommended to mix sesame powder into their food. The same applies to older adults with poor teeth; powdered sesame powder is also recommended to ensure they receive the necessary nutrients.

When should you consult a doctor or nutritionist?

Sesame seeds are a common food, and moderate consumption is safe for most people. However, in the following situations, it is advisable to consult a doctor or registered dietitian before adjusting your diet:

• Known or suspected sesame allergyThose who have experienced symptoms such as rashes, swelling of the face or tongue, wheezing, or difficulty breathing should consult an allergist for diagnosis and treatment. Do not attempt to taste the product on your own.
• A history of kidney stones (especially calcium oxalate stones)Follow your doctor's advice to control oxalate intake and ensure adequate hydration.
• Taking anticoagulants or other prescription medicationsBefore significantly increasing your intake of sesame seeds or sesame supplements, it is advisable to consult a doctor first.
• Patients with chronic diseases such as hyperlipidemia, hypertension, and diabetesSesame seeds can be part of a balanced diet, but...It cannot replace medication and regular treatment.Please follow your doctor's instructions for a follow-up appointment.
• Pregnant women, breastfeeding women, the elderly, infants and young children, and those with weak gastrointestinal functionIt is advisable to use an appropriate amount and to keep it in powder form and cooked thoroughly; be aware of the risk of choking in infants and young children.

If you experience persistent discomfort, suspect an allergy, or your symptoms worsen, please seek medical attention as soon as possible.In case of an emergency (such as difficulty breathing or confusion), please call 999 immediately.。

Frequently Asked Questions

Are black sesame and white sesame two different plants?

No. They belong to the same plant family.Sesamum indicum The difference between different varieties of L. lies in the seed coat color. The real cause of the nutritional differences is...With shell and without shellBlack sesame seeds are mostly sold whole with the seed coat attached, while white sesame seeds sold in the market are mostly shelled kernels.

Why is black sesame seeds so much higher in calcium than white sesame seeds?

Because calcium is mainly concentrated in the seed coat. According to data from the U.S. Department of Agriculture, 100 grams of whole, shelled black sesame seeds contain approximately 975 milligrams of calcium, while shelled seeds contain only about 60 milligrams, a difference of about 16 times. Therefore, the real reason why "black sesame seeds are good for calcium supplementation" is not their color, but rather...Did the seed coat remain?。

How much calcium can one tablespoon of black sesame powder provide?

約 88 mg(One tablespoon of sesame seeds in their shells is approximately 9 grams × 975 mg per 100 grams), which is equivalent to the recommended daily intake for adults (approximately 1,000 mg).Approximately 9%It is not the 50% that is commonly referred to. Moreover, sesame contains oxalate and phytic acid, and its actual absorption rate is not as high as that of dairy products. For daily calcium supplementation, dairy products and their substitutes should still be the main sources.

Can black sesame seeds really make hair black?

It's not something you can directly change. Hair color depends on the melanin cells in the hair follicles and genetics, not the color of your food. While a long-term deficiency in nutrients like protein, iron, and zinc can indeed affect hair health, that's the overall effect of a balanced diet. If you experience persistent hair loss or sudden graying, you should consult a doctor to find the cause.

Are sesame seeds considered nuts? Can people with nut allergies eat them?

Sesame isseedSesame seeds are not woody nuts; nutritionally, both belong to the "oils and nuts/seeds" category. However, from an allergy perspective, sesame seeds and woody nuts are different allergens—being allergic to nuts does not mean being allergic to sesame seeds, and vice versa. However, some people allergic to sesame seeds are also allergic to peanuts or woody nuts, so those with suspected allergies should be evaluated by an allergist.

Can sesame oil replace sesame seeds themselves?

No. Sesame oil contains only fat and fat-soluble components (such as vitamin E and phytosterols). Dietary fiber, protein, and most minerals (especially calcium) remain in the sesame meal after oil extraction. To obtain the calcium and fiber from sesame, you should eat roasted sesame seeds or sesame powder. Furthermore, cold-pressed sesame oil still retains its allergenic properties, so people with allergies should avoid it.

How many sesame seeds should you eat each day?

It is generally recommended to make approximately [number] per day. 10 to 15 grams(Approximately 1 to 2 tablespoons of sesame powder). Sesame is a high-fat food; 15 grams provides about 86 kcal and 7.5 grams of fat, which should be included in your daily total fat and calorie intake. Those with weak digestion or prone to diarrhea should start with a small portion.

Is sesame allergy common? What should I be aware of when buying food in Hong Kong?

Sesame allergy affects approximately 0.11 TP4T in the North American population, is a leading cause of anaphylactic shock in the Middle East, and is classified as one of the fourteen major allergens in the UK. Special attention should be paid to the situation in Hong Kong: the current list of legally recognized allergens under the Food and Drugs (Composition and Labelling) Regulation...Excluding sesame seedsTherefore, local pre-packaged foods are not necessarily required to list sesame seeds. People with allergies should carefully read the ingredient list and pay attention to hidden sources such as sesame oil, sesame paste, dipping sauces, baked goods and processed meats.

Can sesame seeds really lower cholesterol and blood pressure?

There is positive but inconsistent evidence from human studies. In one small study, patients with hyperlipidemia who ate 40 grams of white sesame seeds daily for 60 days experienced a significant decrease in total cholesterol and LDL-C. Another meta-analysis showed that sesame seeds were associated with a decrease in systolic blood pressure (approximately -3.23 mmHg in high-quality trials), but this was highly heterogeneous and the sample size was small.Sesame seeds cannot replace medication, nor can they replace a balanced diet and exercise.The research direction is worth noting, but one should not have excessive expectations.

Can people with kidney stones or thyroid problems eat sesame seeds?

Regular serving sizes are generally fine, but the situations differ between the two groups. For those with a history of calcium oxalate kidney stones, doctors may recommend moderately limiting high-oxalate foods (sesame seeds are one example), while...Staying adequately hydrated is the most important step in preventing kidney stones.Regarding the thyroid, sesame seeds are not a cruciferous vegetable, so concerns about iodine are not applicable. If you have thyroid disease, the focus should remain on following up with your doctor on treatment and iodine intake. Any long-term patient should consult a doctor or nutritionist before adjusting their diet.
