7 foods to avoid when drinking coffee

Drinking coffee can affect the absorption of certain nutrients, reducing or increasing the effects of certain foods.

Coffee is one of the most popular drinks with energy-boosting properties. However, coffee can interact with certain foods, such as inhibiting the absorption of many essential vitamins and minerals such as calcium, iron, and zinc.

The acidity of coffee can also negatively impact digestion, especially when combined with acidic foods like citrus fruits. Its effects on blood pressure and cholesterol levels can also exacerbate the negative effects of fried and high-sodium foods.

Certain foods such as citrus foods, dairy products, fried foods, and fortified cereals should be avoided with coffee.

1. Do not drink coffee at the same time as citrus fruits.

Do not drink coffee with citrus fruits.

Drinking coffee while eating citrus fruits can cause indigestion because coffee is naturally acidic. The pH of coffee averages between 4.85 and 5.13 on a scale of 0-14, with lower numbers indicating increased acidity.

Citrus fruits and their juices are highly acidic and can trigger gastroesophageal reflux disease (GERD), which can cause nausea, bloating and heartburn.

Drinking coffee and citrus together can irritate the lining of your stomach and worsen these symptoms. The flavor of citrus can also alter the taste of the coffee, making it bitter and less enjoyable.

2. Red meat

Research has shown that drinking coffee can affect the absorption of nutrients in the gut, especially iron. Iron plays many important roles in the body, including supporting blood circulation, hormone production, and immune function. Red meat is one of the best sources of heme iron, meaning drinking coffee with a steak may reduce iron absorption.

3. Foods rich in calcium and vitamin D

Some calcium-rich foods such as milk, fresh milk, cheese, yogurt; oily fish, eggs, beef liver (rich in vitamin D) should not be consumed when drinking coffee. The reason is that caffeine can reduce calcium absorption and increase calcium excretion through urine. Although this effect is small for healthy people, for people with underlying diseases or osteoporosis, regular combination may not be beneficial. In addition, coffee can also hinder the absorption of vitamin D from these foods.

Milk is an excellent source of calcium, which is essential for bone health, muscle function, blood clotting, and hormone production. One cup of skim milk provides 23% of the recommended daily value (DV) of calcium for the average healthy adult. However, research shows that combining milk and coffee can reduce calcium absorption. Unabsorbed calcium is excreted in the urine. High levels of urinary calcium have been linked to an increased risk of kidney stones and bone health problems.

People who regularly drink coffee with milk may need to supplement calcium at other times of the day.

4. Fried foods

Regular coffee drinkers may need to limit their intake of fried foods to maintain heart health.

Drinking a lot of coffee may increase your risk of dyslipidemia, or abnormal levels of fat in the blood. Drinking three or more cups of coffee a day may increase low-density lipoprotein (LDL) cholesterol (“bad cholesterol”), which negatively affects heart health. It may also decrease high-density lipoprotein (HDL) cholesterol (“good cholesterol”).

Because frequent consumption of fried foods is associated with an increased risk of cardiovascular disease, people who regularly drink coffee should limit their intake of fried foods to maintain heart health.

5. Fortified breakfast cereals

Many breakfast cereals are fortified with essential vitamins and minerals. For example, breakfast cereals, often fortified with zinc, are a significant source of this essential mineral in many diets.

However, coffee may affect the bioavailability of zinc. While no current studies have analyzed the relationship between coffee consumption and nutrient absorption from fortified breakfast cereals, it is best to keep the two separate.

Research has not established a standardized waiting period between eating cereal and drinking coffee.

6. Foods high in sodium

Coffee contains many bioactive compounds that have a direct effect on blood pressure. Research suggests that drinking 1-3 cups of coffee per day is unlikely to have a negative effect on blood pressure levels. However, consuming too much caffeine can worsen high blood pressure.

Research has repeatedly shown that sodium intake is directly related to blood pressure, so drinking coffee mindfully when eating foods high in sodium may be beneficial. The American Heart Association recommends consuming no more than 2,300 milligrams of sodium.

7. Functional foods

Caffeine can interact with certain medications or reduce the absorption of minerals such as iron, calcium, and magnesium from dietary supplements. If you are taking medication or micronutrient supplements, consult your doctor or pharmacist about the appropriate time to drink coffee.

To enjoy coffee in a healthy way, it is best to drink coffee at least 1-2 hours before meals, especially meals rich in iron or calcium. This helps the body absorb the maximum nutrients from food and limit unwanted side effects.

Consider these ways to maximize the benefits of coffee:

Caffeine can interact with certain medications. People who are taking medications should consult their doctor about spacing out their coffee consumption outside of their prescribed medication.

Consider taking vitamins and minerals like iron, calcium, and zinc with meals. Avoid drinking coffee with meals that prioritize these nutrients, as it can interfere with their absorption.

Coffee should be consumed 3-4.5 hours before meals to reduce the impact of caffeine on the amount of macronutrients in food.

The best time to drink coffee is usually in the morning or early afternoon because coffee can affect sleep.
