The foods consumed before a date could play a significant role in romantic encounters, according to nutritionist Victoria Strandlund. A review of scientific studies suggests that diet can affect various factors, including skin tone, body odor, facial redness, and even pupil size, all of which can influence first impressions.

Foods to Enhance Appeal

Certain foods may help individuals appear and feel their best. Eating more fruits and vegetables, such as carrots, tomatoes, sweet potatoes, and leafy greens, has been linked to changes in skin color, contributing to a natural "glow." One study found that increasing fruit and vegetable intake to approximately 3.3 portions a day was associated with a perceptible increase in skin attractiveness.

Spicy foods, like chili peppers containing capsaicin, can induce facial redness, which some studies suggest can make individuals appear more attractive. However, the aim should be comfort and confidence, not manufactured blushing.

Caffeine, found in coffee, may have a subtle effect on the eyes by increasing pupil size under low-light conditions, though direct evidence of attractiveness boost is lacking. Surprisingly, garlic, despite its reputation for causing bad breath, has been found to positively influence body odor. Research indicated that women rated the body odor of men who consumed more garlic as more pleasant, attractive, and less intense. Strandlund notes that garlic may affect body odor differently from breath odor, advising individuals to be comfortable with potential breath effects.

Foods to Approach With Caution

Several foods are recommended for caution before a date. Red meat has been associated with less attractive body odor in some studies. Fizzy drinks, beans, and lentils can cause bloating and excess gas in sensitive individuals.

While beans and lentils are nutritious, their timing and personal tolerance are key. The advice is to avoid foods that cause bloating or discomfort, especially if trying new options before a date. Sugar-free gums and mints, often used for breath freshening, may also lead to digestive issues due to sugar alcohols.

Strandlund concludes that the most sensible approach is to focus on a varied, balanced diet and choose familiar foods that are known to be well-tolerated.
