When you have anxiety or nervousness, what food should help if there are no medicines available at the moment?

Stay away from caffeine…that’s all I know. That’s what Mr Dr. Told me.

Kristina’s right - no caffeine. Also, avoid additives, e numbers and artificial sweeteners. Eat regularly; potatoes, bananas and turkey are good. make sure you get enough protein as well as carbs.

1. Go Nuts

Nuts, especially Brazil nuts, are high in the mineral selenium. And you don’t need a whole lot of them; a handful of mixed nuts, or just two Brazil nuts, a day will be enough to keep you out of crankiness.
Substitutes: Shitake mushrooms, tuna, cod, salmon also contain excellent amount of selenium, though not nearly half as much as nuts.

2. Eat like Popeye
Eat this: Magnesium helps to keep our nerves and muscles relaxed. Spinach happens to be a magnesium powerhouse, and it’s also a good source of vitamin A, C, iron and folate. Aim for one cup of fresh spinach or half a cup of cooked spinach a day.
Substitutes: Other foods high in magnesium include halibut, pumpkin seeds and peppermint.

3. Heal with Herbs
Eat this: Basil is a good source of magnesium, which helps muscles and blood vessels to relax. Enrich the taste of your food by adding a handful of basil leaves and you get a boost of iron, calcium, potassium and vitamin C.
Substitutes: Lemon balm and chamomile are also popular herbs that can melt stress and reduce anxiety.

4. Give in to Your ‘Dark Side’
Eat this: Tryptophan is an essential amino acid which is used by the body to create serotonin, a neuro-chemical that relaxes the brain. Dark chocolate, aside from its heart-boosting antioxidants, is one food that is rich in tryptophan. When buying, choose one that is high in cocoa solid but low in sugar to get the maximum goodness without the sugar crash later.
Substitutes: Tryptophan occurs naturally in nearly all foods that contain proteins, like almonds, sunflower seeds, sesame seeds, nuts, legumes and red meat.

5. Take Your Oats
Eat this: Complex carbohydrates enhance the absorption of tryptophan, which is in turn used to manufacture serotonin — nature’s Prozac. To get the soothing effect from oats, eat them together with some proteins such as nuts, seeds or dark chocolate.
Substitutes: Brown rice, unrefined grains and legumes are also good sources of complex carbs you can choose from.

6. Say Moo for Milkilicious
Eat this: Is it any surprise that milk has calming effects? Just recall those nights when Mum used to tuck you in with a glass of warm milk. Milk works because it contains the protein tryptophan, which is converted to serotonin. This neurotransmitter not only helps you to relax, but also makes you sleep more soundly.
Substitutes: If you are lactose-intolerant, there’s always plant-based milk to fall back on, like soy and rice milk.

7. Relish the Taste of Ocean

Eat this: Shrimps may be small, but in terms of their nutritious value, they are anything but. These small sea creatures are excellent sources of tryptophan and selenium, which are essential for staying cool. They also contain good amount of omega-3 fatty acids, vitamin D and B12.

Substitutes: Close relative of shrimps, lobsters, as well as fish are viable options that will ensure variety in your meals.

8. Binge on Florets

Eat this: Low potassium levels can cause muscle tiredness, feelings of fatigue and make you irritable and anxious. But good thing we’ve broccoli which packs a generous dose of natural potassium in a nice bouquet of florets. Broccoli is also rich in beta-carotene and vitamins C and E that strengthen immune system.

Substitutes: Alternative sources of potassium include avocado, banana, kale, Brussel sprouts, cabbage, winter squash, eggplant and tomatoes.

9. Start the Day with T
Eat this: L-theanine is an amino acid mainly found in tea leaves and is found to reduce stress, promote relaxation and enhance mood by stimulating the production of alpha brain waves. Our usual awaken state is associated with beta brain waves, while the calmer and more relaxed state is alpha. Green tea is rich in L-theanine and a host of other compounds that make it sounds like the Superman of plant kingdom. It lowers risk of cardiovascular disease and cancer, reduces blood pressure and prevents hypertension, and promotes weight loss, single-handedly. Wow.

Substitutes: Black tea and oolong tea are sidekicks that pack quite a punch on their own. They also contain L-theanine and anti-oxidizing properties found in green tea.

10. Take off with Kiwi
Eat this: Our brain needs adequate amount of vitamin C to convert tryptophan into serotonin. In fact, the brain has a special vitamin C “pump” that draws extra vitamin C out of the blood and concentrates it in the brain. Kiwi fruit is one vitamin C factory that will satisfy your recommended daily intake of vitamin C with just one fruit.

Substitutes: If the sight of kiwifruit makes you shudder, there are plenty of other vitamin C-rich fruits you can choose from. Strawberries, papaya, orange, grapefruit and guava are just some.

Hope this helps.
